It can come as quite a surprise just how much water is lost from a swimming pool via evaporation, due to heat, humidity and wind. Even a gentle breeze can more than double the evaporation rate by removing the insulating layer of warm, moist air directly above the pool surface.

Add to these factors a gaggle of splashing swimmers, and it is understandable that large water bills plop onto your doormat every summer.

However, not all water loss is down to evaporation. Even small leaks can significantly raise the cost of your water bill, and be very difficult to locate. If you think you might have a leak, it is worth having it checked out, not only to lighten your water bill, but because those expensive products might be literally going down the plughole!

The first thing a pool specialist will check out is the location of the leak – pool or filtration system. Special test kits can detect leaks in liners and shells, although for concrete pools, the checks can only be carried out by visual inspection. If the suspected leak is in the filtration system, checks on the pipe pressure can confirm or rule this out.

Once confirmed, a flexible inspection camera can snake its way around the inside of the piping, pinpointing layout, and determining breakage, blockage etc. The camera records the findings, and is checked on a screen afterwards, very similar to a colonoscopy!

Identifying and locating a leak can be a long and complicated process, but well worth it in the long run for economy and peace of mind.

  1. Have a bucket of water near pool and this will show the amount of evaporation as the level falls in the bucket . Will assure you whether leak or not in pool . This summer loss in bucket upto 5 centimetres in 24 hours in Fuilla area .
