  • How to increase pump motor efficiency

    Motor efficiency is a key factor in making pumps more efficient overall and in saving energy when they’re running. Get this right, and you can save money over the whole life of the pump and its motor - this can add up to a significant cost saving over time. However, it’s difficult to put together a package that will perform at maximum efficiency, so you may want to look at packaged pump systems when you’re considering motor efficiency. With these kinds of systems, every component has been designed to work in harmony with the other components to deliver motor, and therefore pumping, efficiency.

    How to Increase Pump Motor Efficiency: Packages pump systems

    There are four main issues which can have an effect on how efficient a motor is:


    The motor should only be run at below 50% of its capacity for short periods. Because most pumps operate with a variable load, a key method of improving energy-efficiency is to make sure that the variable-load mechanism works effectively. Temperature, pressure, the required flow and a number of other factors may mean that the motor speed needs to be adjusted. There are various ways of doing this, and many of the newer motors can improve energy-efficiency by electronically monitoring and adjusting the load.



    There’s a relationship between the speed of the motor and its efficiency, and it’s not always obvious - lower RPMs can be more efficient than higher RPMs, and the motors can last longer. Standard pumps are either off or on and running at full speed. The new “intelligent” pumps available in some packaged pump systems can control the speed of the motor to match the demand on it.



    Motors that are too big for the job they are doing, and therefore under-loaded, don’t run efficiently. A smaller motor that is being run at a higher load is operating more efficiently than a bigger motor that is running below capacity. The smaller motor therefore uses less energy. The larger the motor, the more it is going to cost to run, so you need to measure how much pump power you actually need. Decreasing hydraulic resistance in the circulation system of a swimming pool, for example, will mean that the pump doesn’t need to work so hard. Pipe and filter size can make a difference here.



    Motors rated as highly energy-efficient tend to run at a slightly higher speed for a given load. These motors take advantage of new materials that are available which can be used in improved designs to deliver greater efficiency. When a motor fails, it is generally more cost-effective to replace it with a high-efficiency model than to repair the existing motor, because the repair itself may reduce the efficiency of the existing motor.


    Packaged Pump Systems - Improved efficiency

    All of these factors interact, so one of the ways of running, say, a more efficient swimming pool pump, is to use a high-efficiency pump with a smaller motor and to run it less frequently.

  • Summer water-saving tips for your garden

    Have you ever considered how much precious water we use to keep our gardens looking green and beautiful? There are several ways in which you can reduce your levels of irrigation and other water usage throughout the summer months. Some alternatives may require a garden water pump to boost water pressure or to circulate it efficiently.

    Summer Water-Saving Tips for Your Garden: Garden Water Pumps


    Don't apply water during the heat of the day, as over 30% may be lost to evaporation. It is best to apply water from 6am to 10am, as this ensures that it has time to infiltrate down through the soil layers to be stored at a safe depth rather than being drawn back up and into the atmosphere. Watering at night can result in the growth of mildew and fungi on your lawn or plants, so it should be avoided.

    Don't overwater your lawn or garden, as this can result in disease. Furthermore, run-off can carry pesticides and fertilizer into nearby streams, where it can cause serious environmental damage. How do you know how much you have watered? Place a rain gauge to measure the amount of water falling from your sprinklers. On average, and depending on the grass variety, you should be applying about 1.3 cm of water twice a week. You can check the uniformity of your sprinklers by placing tins such as empty tuna cans around your laws to see that your sprinklers are doing their job properly.

    Watering infrequently but deeply will encourage root growth so that plants will become stronger and are able to tap into water within the soil when there are dry periods. Don't worry too much about your lawn, as if it is under-watered, such as during a drought, it can go into a state of dormancy for periods of up to two months, depending on the grass variety. So if your lawn isn’t heavily used by children or animals, it will do no harm to leave it without water for a while.

    Don't water the street! Check that your sprinklers and hoses are putting the water where it is needed most and not on the neighbour's garden.


    Garden water pumps

    Try using rain barrels to capture water either directly or through the gutters of the house or greenhouse roof. Water can then be stored till needed, and with a small garden water pump you can hook the water up to your irrigation system. With your own pump you can then apply the right volume of water to the specific part of the garden that you need.


    Garden Care

    Raise your mower blades before you mow the lawn to leave a depth of grass that can easily compete with weeds and moss. In the flower-beds, minimize weeds, as both of these reduce soil water content.



    Pond pumps will move water around your pond, which prevents the build-up of harmful bacteria. Healthy water will attract wildlife to your garden without your having to empty your pond on a regular basis. Ponds that contain fish need to have the water aerated, and a well-fitted pumping system will prevent the need to regularly empty your fish pond.

  • 3 plumbing features to check before buying a new house

    More house buyers are getting the plumbing checked before they buy that dream property. It's a good idea to make sure the inspection takes place before any legally binding agreement is made. If there is a problem with dirty water pumps or the sewers, you want to know about these while you are still in a position to negotiate about repairs.

    plumbing features including dirty water pumps to check before buying a new house

    1. Take a good look at the toilets

    These are necessary yet often overlooked. That leak at the base may appear to be minor, but there could be a whole world of problems involved. No leak is ever a beneficial thing, and they don't tend to repair themselves, so beware. As time goes on, the escaping fluid could make the floor directly underneath the toilet rot. Water could even find its way between the sub-floor and the floor beneath that. Trying to fix this yourself could trap water and cause even greater problems.

    It's important to look for signs of leaking at the toilet base, such as stains or warped flooring. Then check to see if the floor has sustained significant damage by testing whether it is yielding in any way. Do this by applying your body weight via your foot at the base. After that, grab the toilet bowl on both sides and attempt to move it. Hopefully, it will feel firm and secure.


    2. Consider the sewers: Dirty water pumps

    They aren't really a subject close to anyone's heart, but if you are in any doubt about the condition of the sewer connection between the prospective new home and the main municipal sewer, then get it assessed. As the sewers are often many feet below the surface, repairs can be extremely costly. It is possible to use a camera to investigate any possible clogs and to examine the state of the drain. If it is about to collapse, then this is something you should know. Any dirty water pumps might need replacing too. Any drainage problem needs to be investigated fully to prevent a lot of stress further down the line.


    3. How are the water heaters holding up?

    Depending on the quality of the water, maintenance and how much the heater is used, the typical model lasts around a decade. If the unit is heating your home as well as your water, its life could be considerably shorter. Water heaters can suffer from a variety of maladies, so these are another important feature to look at. If something goes wrong, it is not just the heater you have to worry about but the surroundings, too. If the tank leaks, will it ruin expensive hardwood flooring? What about the carpets? The heater may be located in a garage, but if it malfunctions and leaks, any flooring on the same level is vulnerable.

    Although often placed in areas where they are barely noticeable, a leaking water heater will cause damage that will be extremely noticeable. Employ a licensed plumber to check the state and age of the heater, along with whether it is matched to the size of the home and the needs of your family. Sometimes a large water heater has been replaced with a small one that will not be adequate.

    If you engage a professional to look at the plumbing, it is an excellent idea to arrange to be there with them as they conduct the inspection. Ask lots of questions and take notes. Spending a little extra on this procedure could make a big difference between feeling happy with your intended purchase or rethinking whether you really want to buy it at all.

  • How to hide bathroom plumbing

    Some people are happy with exposed pipework when they are renovating their bathroom and giving it a period look; indeed, this can fit with an antiquated scheme. Many of us, however, want a sleek, streamlined look in which pipes are not visible and the shower pump is hidden.

    How to hide bathroom plumbing and shower pumps

    Unfortunately, concrete floors mean that pipework is often exposed after a renovation. Many modern bathroom fittings hide their pipework; however, it is not always possible to buy items that feature hidden utilities and replacing an entire bathroom with newer pieces is expensive.


    Boxing clever with your shower pump

    The classic solution is to box the pipes in; however, if you choose this option, be aware that a loosely-fitted box that is not properly sealed can enable damp to get in, which in turn can encourage the growth of mould. This is particularly true for fittings such as the bathroom shower pump. If you are using MDF for the boxing, make sure that you buy humidity-resistant MDF. Even if you do, it may be a wise precaution to paint the boxing with anti-mould paint.

    As with all concealed pipework, the box will need to be accessible in the event that a plumber needs to fix a leak or find a valve; therefore, use screws that can easily be unscrewed if necessary. Any boxing that is near the floor can act as a low shelf and an effective treatment is to tile the box so that it looks like a bathroom shelf for storing items such as toilet rolls and magazines.


    Wall them up

    A far more finished - but also more expensive - option is to hide pipes in the walls. If you are going to do this, make sure the pipes are firmly secured inside the closure, as you don’t want them to move and start banging when they are under pressure.

    Chasing pipes into walls can cost a lot of money in labour, however, and some people look at this and decide that a cheaper option would be to build a false wall to hide the plumbing, including items such as the shower pump. This is fine if your bathroom is big enough, as it reduces the size of the room - although not by a huge margin. Give the false wall a finish that blends with the rest of the bathroom, such as matching or toning tiles.

    Another way to hide pipes is to replace items such as a hanging sink with a sink sitting on a pedestal. In this way the pipes are hidden inside the pedestal, giving a more professional look.



    The replacement of an item such as an old shower pump with a more effective modern version sometimes necessitates new pipes in the bathroom. If you really don’t want to spend much but are reasonably handy, shelving is a good way to hide pipes that run along the wall. Once the shelves are up, you can use them to stack towels that have enough bulk to conceal the pipes behind them. If any of the pipes are carrying hot water, the towels will be nicely warm when you come to use them.


    Ready-made pipe trunking and retro options

    A number of DIY stores sell ready-made pipe trunking in various finishes; however, if you look at all the hidden pipework options and don’t feel that any of them are for you, there is always the option of turning the pipes into a thing of beauty by fitting antique brass pipe covers and keeping them shining with a weekly polish.
