  • How do drainage pumps work?

    drainage pumps

    Drainage pumps are often installed to move waste-water from a range of domestic and industrial sites, including private housing, farmland, and construction sites. They deal in underground dewatering, usually when gravity can't be applied to move the water (in this respect a drainage pump is similar to a sewage pump). What a drainage pump does is effectively ‘what it says on the tin', however, how they do it is a different matter entirely. This article aims to introduce the how's and why's of non-submersible and submersible drainage pumps.  

    Non-Submersible Drainage Pumps

    A non-submersible drainage pump is not placed directly in water; instead, it uses suction hoses and permanent pipework to transport the waste-water from the unwanted location. This type of drainage pump is often used when pumping waste-water from ponds, and other mobile drainage requirements.

    Submersible Drainage Pumps

    The reputable pump manufacturer Grundfos defines the submersible pump as "an enclosed unit with a close coupled pump and motor, due to its construction, the pumps are suitable for submersible installations – designed to be partially or completely immersed in water."

    A submersible drainage pump will collect water from the base of the unit and transport the water up and out of the system and include a no return valve to ensure there is no potentially damaging backflow. To use the ABS Coronada 250W-SX as an example, it is optimised to work when submerged in several ways. Firstly, the unit is encased in corrosion resistant stainless steel which is vital for the products durability – the model is also equipped with thermal sensors in the motor to prevent overheating. The Coronada is also equipped with the previously mentioned no return valve.

    The Calpeda GXRm 11 fits the similar purpose of draining rooms, water extraction, and can also clean water containing solids of up to 10mm in size. Its operating systems differ in various ways from the Coronada, for example in the Calpeda the motor is cooled by the water passing between the motor jacket and external jacket. However, both jackets are similarly corrosion proof – making both these submersible drainage pumps excellent units for domestic use.  

    Submersible Drainage Pumps & Industrial Use

    An industrial site naturally includes different working conditions when compared to the domestic setting – the Trencher T400F automatic submersible drainage pump is an excellent example to consider concerning industrial conditions.

    Whilst this pump is undoubtedly suited to a residential environment, what makes it uniquely suited to industrial sites is its adept handling of water supply from lakes and rivers. The Trencher is excellent when dealing with sediment removal thanks to its high abrasive resistance resin vortex impeller– which is something more common in industrial sites that often handle raw materials, thus this feature is less likely to be needed in a suburban estate.

    Every pump adheres to its specifications and operating systems, they often share a common purpose but when looking at the ‘how', one must look carefully at the detailed specification pdf's that are regularly available to select the correct drainage pump for you.

  • The UK Locations Most At Risk of Flooding

    As global warming continues its march relatively unimpeded, sea levels and the incidence of tumultuous weather will continue to rise. And while many may assume that coastal regions of the UK are far and away the most susceptible to flooding, data collected by the Environment Agency actually shows that the network of rivers and tributaries that wind their way throughout Britain make inland areas just as vulnerable.

    Boston and Skegness

    It is however, a coastal region that is most in dangerous in terms of flooding. Boston and Skegness, both perched precariously on the Lincolnshire coast, are subject to frequent storm surges that plague that particular stretch of the east coast. When deep depressions track across the Atlantic Ocean (resulting in lower pressure and rising sea levels) winds push the surface waters forward as part of a process known as wind drift. When these depressions reach the North Sea, they are forced southwards. Because this water cannot escape through the Dover Strait, it accumulates in this region and causes sea levels to rise dangerously, afflicting the east coast in the process. Just earlier this month, over 3000 residents were forced to evacuate their homes in the face of warnings of gale force winds and high tides.

    Nottingham

    Nottingham is perhaps the most populous area that is perpetually under threat of sustaining damages from flooding. The city has been associated with flooding throughout its history, so much so that indentations marking the height of its historic floods have been engraved into Trent Bridge since 1852, and had been marked into the Hethbeth Bridge before it. The concern over flooding is so dire that £1 million of funds have been invested into flood defences to protect the Mapperley Park region of Nottingham. Everything from flood-resistant doors to storm gullies is under consideration.

    Vale of Clwyd

    The low-lying nature of the Vale of Clwyd puts it in jeopardy of regular flooding. The Welsh region owes this unenviable status not only to how low-lying it is, but also to its proximity to both the River Clwyd and the Irish Sea. Any time flash floods are forecast, more than 137,000 properties are at risk of being enveloped by water. The floods that devastated the region in 2012 are just one example of the area being affected by flooding.

    Windsor

    lowara pumps uk

    The River Thames continually threatens to put the residents of Windsor at risk. The 5000 residents that call the river’s banks their home have experienced severe flooding numerous times over the course of the last decade - the worst of which was the floods of 2012. The majority of residents were affected and train lines were wrought with delays and cancellations.

    If you live in an area that poses a risk of flooding, it is well worth opting to buy from lowara pumps UK. With a wide range of drainage and sump pumps available, a Lowara pump is a dependable ally for anyone who is wary of flooding affecting their home.

  • Keeping your garden pristine in adverse weather

    Maintaining a garden can be a trying undertaking at the best of times. When the weather isn’t quite in your favour, the work involved can be excessive. Fortunately though, there are a number of measures you can take to ensure the garden that you have invested hundreds of hours of work into remains pristine even in adverse weather conditions - from droughts to floods. Solutions range from permanent to temporary; some require a transformative change in your approach to plant cultivation, whilst others require nothing of the sort.

    Rain

    tt pumps

    Floods caused over £1.5 billion worth of damage during the UK floods of late 2015 and early 2016. Rain is essential for the growth of almost every garden plant yet an overly excessive outpouring can derail the health of even the sturdiest garden. Whilst us Brits are more than well accustomed to receiving our fair share of rain, sometimes it can overwhelm and lead to floods - especially if our gardens lack adequate drainage and runoff.

    The only immediate and 100% effective response is to employ a submersible drainage pump. The trencher range of tt pumps is particularly well-equipped to handle water containing sand and silt, which is common with a flooded garden.

    Wind

    As we transition from summer to autumn, the likelihood of stronger winds multiplies. Burgeoning plants are best supported by wooden stakes that help to prevent them from wilting under the pressure of strong winds. A similarly simple and straightforward countermeasure you can take to safeguard your garden is installing a temporary windbreak - plastic screening tied to a couple of posts is probably your best bet.

    More permanent and natural alternatives require a slightly longer-term approach. Interspersing layers of trees and shrubs can generate a natural windbreak. Similarly, electing to keep trees that border a garden can help to protect the plants within from wind damage.

    Drought

    I am sure the suggestion that areas of the UK are likely to experience drought is likely to raise a few eyebrows, but the effect of climate change has already been dramatic, and drought is a very real prospect every time summer comes around. Ways of combatting drought can consist of the complex and exciting (xeriscaping) to the simple and the mundane (adding mulch and compost).

    Xerophytes are organisms that can survive with little to no water, and are therefore more than capable of outlasting a British drought, which is defined as 3 or more weeks where less than a third of the typical volume of precipitation falls. Acclaimed because of their ability to take on a drought, xerophytes are also popular because they require very little maintenance, making them a very strong choice when a lack of rainfall is predicted. They do however; require an overhaul of your garden if you plan on adopting this approach for your garden in its entirety.

    Simply adding mulch and compost are two far faster and cost-effective ways of fighting drought. Mulch can help off-set high temperatures by up to 10°C, ensuring the soil stays cool and the roots of your plants are able to uptake moisture.

  • How to prevent your home flooding

    Unfortunately, as climate change rages on and continues to worsen over time, so too, does the risk of flooding. Over the past few years, we have seen flooding become an increasingly frequent topic on the news, with intense rainfall causing over £1.5 billion worth of damage in late 2015/ early 2016 in the UK. No longer is flooding something to marvel at with a sense of morbid curiosity as it affects other areas across the globe, flooding is now a very real threat at home as well as abroad.

    How then, can you best defend your homes, containing everything and everyone you love, from flooding? The bad news is this - it isn’t going to be a cheap. The good news is that we are here to advise you on the most cost-effective and worthwhile changes you can possibly make to protect your home.

    Covering air bricks

    air brick

    Air bricks are an easily overlooked flaw in any home’s composition. As effective as they are at allowing air in for ventilation purposes, they are also effective at allowing water into your home. The solution to this problem depends on how much money you want to spend. Smart airbricks have water sensitive valves that close when water is detected. Pretty clever? As you’d expect, they are pretty expensive too. The alternative is a vent guard, which can be snapped shut when relentless rain is forecasted. Less expensive, but also less visually appealing.

    Alternatives to sandbags

    sandbags

    Sandbags are the traditional defence against flooding, but they are also the outdated defence too. Absorbent polymers are the new sand. The reason they are so popular is down to the deficiencies of the sandbag - they are tricky to store, not to mention move, owing to their size and weight. The new school of sandbags only increase in size and weight with the arrival of water, and do not leave behind the same melted pile of sand afterwards.

    Regular maintenance

    window sealant

    While you may be tempted to invest in some of the more heavy-duty anti-flood measures like an anti-flood door, these are unsightly as well as expensive. You would be better off ensuring your home is properly maintained. An anti-flood door is redundant if you have gaps in your roof. That is why it is worth the hassle of having a tradesmen round to shore up your home’s first line of defence against the elements. Doors and windows can be sealed off and any gaping flaws in your roof can be addressed and amended.

    Submersible drainage pump

    ksb pumps uk

    All of these precautions are undoubtedly helpful, yet none of them are capable of providing a 100% fool-proof barrier against floodwater. The one thing you can rely on to be effective is a submersible drainage pump. And there is no better manufacturer to buy from than ksb pumps uk. As well as being renowned for their reliability, the sheer range of variations that are available mean that there is bound to be a pump that is tailor-made for you.

  • How the human race is defending itself against flooding

    Although it might not feel like it, the UK is widely expected to suffer a drought in incoming months. And whilst it may seem like the worst time to start preparing for a flood, it is arguably the best. Floods are often so damaging because the defences made to combat them are often a case of too little, too late. And, unlike a waterlogged garden, you can’t just use drainage pumps. Through months, and sometimes years of preparation, areas of the world have been able to successfully defend themselves against floods. Here are some of the most interesting cases.

    Flood barrierdrainage pumps

    The Eastern Scheldt storm surge barrier in the Netherlands is the largest of its kind in the world. Designed and constructed in response to the devastating 1953 North Sea Flood that proved fatal for thousands, the Oosterscheldekering (as it is also known) incorporates 4 kilometres sluice-gate-type doors that are only closed during adverse weather conditions. It has been so successful that (as part of the broader Delta Works project) it has been named one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.

    Hydroelectric dam

    Whilst the Oosterscheldekering is essentially a flood barrier, the Three Gorges Dam in China also doubles as a hydroelectric dam. Because of its 22 cubic km flood storage capacity, the dam is slated to reduce major downstream flooding as an incidence from one in every ten years to one in every hundred years. Alongside its proficiency as an anti-flood measure, the Three Gorges Dam also provides enough electricity to provide for 3% of the national demand.

    Channel modification

     In order to circumvent the pooling of rivers that causes flooding, the river course can be widened, deepened and straightened, to make the speed of flow of the water faster. Channel modification has been carried out on 25% of all the main rivers in England and Wales. While it is clear that channelisation has helped to reduce the risk of flooding, it can also have negative ecological repercussions - the dredging of the Charlton River in northern Missouri in the US caused the number of species present in the modified areas to fall to 13. In the natural areas of the river, 21 different species remained.

    Managed/ ecological flooding

    Ecological flooding is a more recent approach to combatting flooding. Why would you encourage the very thing you are trying to prevent? The answer is that, whilst you are allowing flooding to occur, you are only allowing it to happen in areas that you specify, which prevents it from happening in the highly areas you do not want it to happen. Aside from - diverted floodwaters away from settlements, managed flooding also aids the animal kingdom. An investigation of the ramifications of managed flooding in south-eastern Australia, found that it promoted the diversity of species present.

    Afforestationdrainage pumps

    Afforestation is potentially the most environmentally friendly anti-flood measure. By introducing more greenery, more rainwater is intercepted and used for photosynthesis and consequently prevented from ever reaching the river. The Mississippi River is one notable example of how this approach has paid dividends. As a counter-measure to the 1993 floods, a programme of afforestation was pursued and it has ultimately helped to reduce flooding by reducing the river discharge.

    With global warming making summers drier but winters wetter, do you think we should be doing more to combat the threat of flooding?

  • How major sports teams are leading the energy-saving revolution

    Sports teams have some of the highest energy bills in the world. With upwards of 80,000 fans attending each game, vast amounts of energy have to be harvested in order to accommodate for it all. Thousands and thousands of air miles are clocked up every year by fans and players alike. Food, drinks, and toilets cater for fans, while groundskeepers, in conjunction with an array of machinery and fertilisers, work tirelessly to provide a supreme surface for play. Somewhere amongst all that energy consumption, there must be some room for streamlining, right? Thankfully, these teams are taking steps to remedy this.

    shutterstock_136818503 Allianz Arena

    Bayern Munich - Allianz Arena 

    Metal halide fixtures have traditionally dominated the lighting of major sports stadiums, but LED lighting is slowly but surely turning the tide. Without needing 30 minutes to warm up to full brightness and with far greater energy efficiency, LEDs are saving time and thousands of kilowatts of energy. Bayern Munich has teamed up with electronics giant Phillips to launch an expansive layer of lights that completely covers the outer shell of the Allianz Arena. Energy efficient LED lights result in a 60% energy saving, and 38000 of them combine to form the impressive outer membrane which is capable of reproducing an astonishing 16 million colours.

    San Francisco 49ers - Levi’s Stadium

    The first NFL stadium to achieve the LEED Gold status for new construction, the 49ers’ Levi’s Stadium has a tremendous capability for energy-saving. One such innovation is a geothermal hot water pump that absorbs the energy generated by the sun drenched ground that surrounds the stadium and uses it generate a supply of hot water. Testament to the success of the stadium is the fact that they are able to recycle a startlingly high 85% of their water.

    Melbourne Storm, Melbourne Rebels, Melbourne Victory and Melbourne City - Melbourne Rectangular Stadium

    The Melbourne Rectangular Stadium is certainly the most visually striking piece of architecture on the list. Home to four Melbourne teams across football and rugby, the unique geodesic design allows light to filter through to the pitch whilst covering the spectators. In a similar fashion to the Allianz Arena, the Melbourne Rectangular Stadium is also kitted out with thousands of LED lights on its exterior, giving it the ability to perform ‘light shows.’ Prominent artists have worked with stadium engineers to create specific sequences for different events.

    Forest Green Rovers - New Lawn

    While we appear to be slacking when it comes to energy saving compared to our neighbours across the pond, some teams are still taking a stand. Conference Premier side Forest Green Rovers became the first in the UK to play on an organic football pitch. They believe the higher cost of organic materials is off-set by the savings made from the long-term benefits to the soil. Not content with just that illustrious title, the club has also installed 170 photovoltaic panels and a solar-powered autonomous lawnmower.

    From harnessing solar energy to maximum effect to making use of more efficient lighting fixtures, it is obvious that many sports teams are keen to be more energy efficient. Often blamed for their excessive waste of energy, it is pleasing to see sports teams taking steps to rectify this issue.

  • 6 home modifications to help you save energy

    Money doesn’t grow on trees so we’ve put together six simple modifications you can make to your house and garden that will help you save on energy bills.
    drainage pumps home modifications to help you save energy

    1. Insulate or top up your insulation

    First, insulation. Not very glamorous and in fact hard to see once it’s done, but what a difference it makes. It can turn a draughty old property into a cosy home. It’s estimated that a quarter of the heat in a home is lost through the roof if it’s not properly insulated, and the payback is immediate.

    You may think that your roof has been insulated, but if it was done a few years ago, it’s probably nowhere near the standard of insulation that is now regarded as adequate. If your roof space is not too complex or irregular, you can try doing this as a DIY job. Use mineral wool, which is available in rolls. Start by putting a layer between the joists, and then put the next layer at right angles to cover the joists and achieve a sufficient depth.

    Be aware though that while the house is warmer, the roof space is colder, so any pipes in the roof will need lagging.

     

    2. Double-glaze doors and windows

    As well as making the house much quieter, and which of us wouldn’t welcome that, this will have a major effect on keeping draughts out and heat in. Other advantages include no more rattling window frames if you live in a windy area, so you can enjoy improved sleep and warmer mornings.

     

    3. Consider changing your boiler

    This is a somewhat controversial area, and you need to balance the energy-efficiency of new boilers with their shorter life and higher maintenance costs. With a new boiler coming in at £2,000, it’s not something you want to replace often. Yet some of the new energy-efficient boilers have poor reputations for longevity. And they really need to be on a monthly maintenance plan, which makes them less cost-effective. You need to weigh up your heating needs and consider the size of your house and the region you live in.

     

    4. Invest in a programmable controller for your heating

    One degree down on the thermostat is equal to 3% down on your energy use and therefore on your bill, so take a look at your thermostat. But once you’ve done that, make sure that your programmable controller is reflecting your heating needs and isn’t running when you’re at work. When the clocks change, adjust the heating timer straight away.

     

    5. Replacing drainage pumps

    People who use drainage pumps for ponds or swimming pools need to make sure they’re up to date. The new models are far more energy-efficient and retain suction, so they don’t have to be run for so long.

     

    6. Invest in new appliances

    You may think your freezer is a low-energy appliance, but you have to remember that it is on 24/7, so any reduction in the energy it uses is going to pay a big dividend. It’s worth getting a super-rated fridge and freezer next time, because these both need to operate at maximum efficiency. And keep the freezer filled as far as possible, because an empty freezer is even less efficient.

    Shop our drainage pumps online now. With these provisions in place, you should be sitting smugly when the next lot of winter storms rolls in.

     

  • 5 signs you should call a plumber

    Plumbing problems vary in severity, from a simple dripping tap to more serious flooding requiring drainage pumps. You can tackle some issues yourself; however, other plumbing problems require the expertise of a trained professional. If you encounter any of the following scenarios, it is time to call in a pro!

    drainage pumps

     1. The pipes are frozen solid

    Anyone who has been misfortunate enough to experience frozen pipes knows that it is best to call a plumber immediately. Generally striking during the winter months, frozen pipes can crack or burst, leading to extensive flooding and water damage to your home and possessions.

     

    Rather than taking a chance with a DIY pipe thawing, leave it to the experts. Call the plumber the moment you notice the pipes are frozen, before they rupture, to avoid a mess that might require the use of drainage pumps. See more information on how to prevent frozen pipes.

     

    2. Water pressure is inconsistent

    Many people simply put up with poor water pressure, writing it off as nothing more than a mild inconvenience; however, this can be a symptom of a far bigger problem. If you only experience poor water pressure with a single shower or tap, you may simply need to clear the fixture of a solid mineral accumulation; on the other hand, weak pressure throughout the house could indicate a larger problem with the mains supply line.

     

    Only a trained plumbing professional can diagnose the problem correctly and take the necessary steps to fix your water pressure, enabling you to enjoy strong, refreshing showers again!

     

    3. The taps won’t stop dripping

    Perhaps the most common plumbing issue, dripping taps are equally often dismissed; however, the constant dripping adds up over time, with a leak of one drip every couple of seconds amounting to around 1,500 gallons of water over the course of an entire year. This is bad for the environment and bad for your wallet!

     

    A persistently-dripping tap could also be a symptom of a much larger problem. A professional plumber will be able to uncover the true source of the leak, so don’t hesitate to give them a call.

     

    4. The bath won’t drain without using drainage pumps

    Blocked bath tubs only get worse over time; for this reason, it is best to deal with the obstruction as soon as possible. Not only can a professionally-trained plumber clean out the blockage but also they can make sure this is not part of a larger issue with your pipes and drainage.

     

    Catching the problem early will make it a lot easier to deal with; therefore, it is best to give your plumber a ring when you notice the bath draining slowly (as opposed to a solid blockage).

     

    5. The toilet is blocked - and even a plunger can’t help

    A blocked toilet is a pain at the best of times; however, if it still clogged up after you have had a go with the plunger, you should call your plumber urgently. Depending on the severity of the issue, the problem could go all the way back to the sewage main, which is why your domestic plunger won’t cut it.

     

    Trying to shift the blockage yourself could scratch the porcelain or damage the main; therefore, it is worth consulting a professional who can bring the tools and knowledge to get your toilet flushing again.
