Frequently Asked Questions
Q What is a pump system?
A pump system is the entire system from the source of your water - your well, borehole, or other source, to the point at which it is used - and everything in-between including pipe work, storage tanks, subsequent pumps, filtration, pressure vessels etc.
Q What sort of pump do I need?
For a source pump this depends on two factors. One, the depth of your bore or well and the volumes of water which you expect to need and two, the total amount of lit which is required to bring that water to the surface. If your well or bore is very deep, you will need a more powerful pump, even if your requirements are modest as it takes a lot of energy to lift water vertically. This type of pump is for getting water out of the ground often from great depths and depositing it into a tank or tanks above ground.
Storage tank submersible pumps are generally much smaller. These types of pumps do not need to lift water more than 2-3 meters, but are able to push water over vast distances. It is this type of pump which delivers the water to you for your final use.
Depending on the volumes of water to be moved and the distances involved, single or three phase pumps may be used. In general for most scenarios, single phase pumps ranging from 750 watt to 2 Kw are all that is needed.
Q Do I need a water storage tank and if so, what size?
For most scenarios we always recommend a water storage tank. This tank, or series of tanks may be sited above ground under cover, - in some out building or other enclosure for example, or may be sited in the ground in a purpose built chamber. Tanks above ground which are not under covered will either need to be shielded from frost - or built of a special type which resist's frost.
Installing storage tanks offer distinct advantages over pumping directly from a well or bore. The heart of your system is your bore or well pump. It is often the single most costly item in the system and is beneficial not to have this pump switching on and off every time there is demand. Instead it is better to pump your well or bore water to a tank - a second stage if you will, from which your water is then delivered to your network via a tank pump.
Tank size is calculated as a portion of your water requirements. For example, if you need 2 tonnes a day and your system suddenly develops a problem, you either have to do without water until the system has been repaired, or you must switch back to mains water - if you have mains. A 2 tonne tank means you can continue using your water, and have a day in which to isolate and fix the problem.
Suddenly finding yourself without water may be inconvenient if the water is simply for a home situation, but if your pumping water for commercial use, this could be costly to your business. Having a storage tank which can store a portion of your water needs gives you time. You can continue operating as you effectively have a reserve.
A storage tank buys you time to get any problem fixed, enables you to continue using your water, reduces stress on your bore or well pump system by not have it operating constantly - and in general gives you better control over your entire system.
Q Do I need filtration?
If you asked this question before 2009 then the answer to this question depends on the results of your water analysis tests. However by law you MUST have the minimum filtration which is a UV and sediment system. A drinking water standards regulation was passed in 2009 to safeguard you and anyone who comes into contact with your water supply.
It is your responsibility to ensure your water meets these regulations. We can assist you with all requirements however if you wish to continue using the water without abiding to the regulations we will struggle to help you as it will then lay as our responsabilty.
If you're water test results shows no adverse content whatsoever, we would always install a simple ultra violet filter at the point of use if you intend to drink it so it is effectively futureproof and ensure all bacteria is removed before drinking it. However, if your're pumping directly to an irrigation system for example, usually no filtration is required, though a pH adjustment may be necessary to protect the your irrigation equipment. Other forms of filtration for example, might be if your test results show high levels of iron, manganese, lead, or any one of a host of other metals, or if your water is excessively hard or soft. To read more on testing, look at our water testing FAQs page, and for a comprehensive summary of filtration, look at our Filtration FAQs page.
Q What is a pressure vessel and do I need one?
A pressure vessel is a pressurised cylinder which attempts to maintain equilibrium of even water pressure (Bar) across a system which has several or many points of use. If your storage tank pump is going to deliver water to 3 or more points of delivery, using water at one point may cause a sudden drop in pressure at another point.
This may or may not be a problem depending on what you're using the water for. Some uses may be pressure sensitive or critical whilst others are not affected by drops in pressure. We have all experienced being in a shower, happily lathering yourself, and somebody turns a tap on! Whilst this is far from critical and is simply unpleasant, if you're using equipment which is pressure sensitive or critical, maintaining even system pressure (Bar) across your network may be essential.
