Don't panic - having a leak isn't necessarily a major problem. There can be many reasons for a leak to develop and below are pointers for sourcing and fixing the most common and simplest of them.

1. Common Causes of Leaks:

If you think you may have a leak there are a few things to check but first confirm that there is one.

a) The simplest way to check is to mark the water level with a piece of tape at the Skimmer and leave for 24 hrs. If the water level has dropped more than ¼“ (0.6 cm is normal evaporation for one day), then you have a leak. 

  • b) Alternatively fill a plastic bucket with Swimming Pool water and a weight, a brick or rock will do, then set it on a step. Ensure that the levels of the water on the outside and the inside of the bucket are the same, mark the inside and outside levels. After 24 hrs if the drop in level is greater on the outside than the inside then it confirms a leak. Do this test once with the pump running and once with the pump off. 

2. Next step is to find the leak:

Look at your plant equipment – Filter, Pump, Pipe Valves and joints etc. Can you see any wet or damp patches around the equipment or the pool? If you have a Liner Swimming Pool then have a good look for any tears or bad joints around any fittings.

If you can’t see anything obvious then turn off the Filter System and see where the water level drops to.

If you have a Liner Swimming Pool then make sure the level does not drop too fast or too low as this can cause damage - if this happens add water and call your Pool Supplier.

If the water level drops to bottom of the Skimmer opening - it is likely to be leaking from the Skimmer or Filter System.

To check your Filtration System – With the Pump running can you see bubbles in the return line? If this is the case then the Filtration System has a leak in the suction side. Make sure that the lid of the Pump Basket is on tight and the ‘O’ ring has lubricant and has not perished.

If the water level drops to the Light - then the leak is most likely to do with the Light fitting/housing

If the water level drops below Light – this could mean the Drain is leaking

If the water level drops continuously whilst the Pump is running – check backwash or waste line as this means that it is leaking on the return side.

3. Skimmer, Liner or Light - if you think the leak is caused by any of these take a close look for tears, gaps, cracks and anything that looks misaligned or odd:

With the Pump off and the water still, place a drop or two of a Leak Detector Dye next to the suspected area and see if it is sucked in; if it is, then there's your leak. 

4. To Fix:

Skimmer – this is often caused by a gap between a Concrete Tiled Swimming Pool and the plastic Skimmer and can usually be fixed with pool putty.

Lights – a more difficult fix as it is often the conduit pipe that has broken, separated or come apart, it can be done with a two part epoxy, putty or silicone.

Liners – use a vinyl repair patch kit, make sure it is suitable for underwater if needed.
