If you decide to contact us try to have the answers to some of the questions below at hand as this will help us and speed up the leak detection process – Leak location/detection can be easy or it can be like looking for a needle in a hay stack …
With your pool pump running / working check the pool filter backwash / waste line plumbing pvc pipework. Your filter top ( MPV = multiport valve ) maybe leaking internally when it is in the Filter position and dumping pool water out of the backwash / waste plumbing without you being aware. – usually when the pump is working. Check the drain where this backwash/waste pipe ends up if possible – it should be obvious, follow the pipe out of the box/room etc. This may only be a small drip but this adds up after a few hours / days. This only gets worse, get it sorted ASAP. A very common problem usually found on older systems. An easy check and usually our starting point in the process.
1. Is your pool leaking or is it Daily evaporation? if unsure, try the The Bucket Test ( refer short video below ) first, with the pool pump turned off and no rainfall or heavy winds in the forecast. You need dry, calm/stable weather for any kind of accuracy here. Watch the short video below a few times.
2. Is your pump or any other piece of equipment or plumbing in your pump room / box leaking / dripping? is there any water evident on the floor etc? Detective work and diligence is required here. You could miss something very obvious.
3. Do you have any “air bubbles” returning to the pool through the return jets located on the pool shell with the pump running. if you have air present it should be very obvious. Unplug your pool cleaner and remove your vacuum plate from the skimmer box ( if you have 1 installed ) and then check. Obviously ensure that the pool water level is correct at this time. There should be no air bubbles returning to the pool via the return jets if you have done the above and you have an air tight system.
4. Does the pool lose water when the pump is running only? or does it lose water when the pump is OFF or ON? ( either or? ) or both conditions?.
5. Make a mark on the pool shell and try to establish how much water the pool is losing over a 24 hour period. Measure this daily loss around the same time and record in mm. This gives a little indicator of what size leak we are looking for. This may not work in the rainy season of course. Pick a dry time/spell with stable weather conditions i.e not too much wind over the pool surface.
6. You should be asked if your pool shell is … concrete / fibreglass / plastic liner or a.n. other and the approximate age of this pool.

Proper Pressure testing procedures must be followed to avoid injury or damages
When pressure testing swimming pool plumbing for leaks we Always use water only to start with. Once you are sure that the PVC line under pressure is Leaking and not holding pressure we then remove the water supply and inject air into that line. The water under pressure that has escaped through the crack/s usually “pools” around the crack/s and when you inject air into the same pipe the air will get out at the same spot/s and you should/may hear a bubbling sound below the ground where the leak/s are eg. like using a straw and blowing air into a glass of water. It is very seldom that we need to take the injected pressure above 12PSI to establish a leak/s. Monitor the pressure gauge and do not stand in front of or above any pressure plugs or bungs that have been inserted. You could get hurt if they blow out. You need to stay ALERT and pay attention to ensure the Safety of everyone involved.
