Naturally, the loss of water from your swimming is expected through evaporation, backwash wastewater, and splash-out when people are swimming. Pools are designed in a way that they are watertight. The inlet and outlet systems preserve as much water as possible. However, the regular circulation of the water causes the deterioration or wearing of the sealants, which may lead to leaking. Water can leak through the fittings on the pool or the accessories used to facilitate its functions such as the pump and the filters.

Detecting and repairing leaks in the swimming pool is a specialised area in the industry. Professionals are tasked with detecting and repairing the leaks. However, before you call the professional to begin further diagnosis, here are few ways of detecting leaks in your swimming pool:

Inspect the areas around the pool

Look at the pump and the filter for any wet areas. Examine the joints and the valves linking the pipes for any wetness. Besides the filter and the pump, walk around the pool, checking for wet ground or sunken areas. The wet ground may be a result of water seeping from the pipes circulating water between the pool and the pumps. Alternatively, the water may be coming from the walls of the pool in the ground, causing wetness. In case you detect any of these signs, contact a professional to assess the extent of the problem and initiate repairs.

Using your equipment to identify leaks

You can determine the nature of the leak when the equipment is running and there has been much change in the level of water over a particular period. Switch on the filter pump and check for bubbles in the pump basket. This is possible if the pump's lid is transparent. Another sign is the accumulation of air in the pump. These signs indicate leakage on the suction side (equipment that suck water from the pool back to the pump). The air bubbles show you that water is being lost and there is a vacuum in the channel.

The pressure side, whose role is to supply water from the filter to the pool, accumulates much pressure when the pump is running. Therefore, the plumbing on the pressure side fills with water. You can notice gushes of water from the pipe in case there is any leakage.

Examining the water loss levels

Take some water in a bucket and mark the water level after immersing sinkers in the bucket. Put the bucket on one of the staircases used to enter the pool such that a part of the bucket is exposed. Mark the level of the pool's water on the outer side of the bucket using visible tape. Check the bucket after a certain period, say 24 hours. If the pool's water level has changed more than the water level in the bucket by a significant margin, then there is leakage. It shows that the pool is losing water in other ways besides evaporation.

Contact your pool plumbers for further analysis and repair in case of the above signs.
