Pools lose water through evaporation, splash out and backwash waste water. They also gain water from rainfall. Under normal circumstances, you only need to add two inches of water to your pool in a week. In case you are adding more than this, it is possible that there is a leak worth spending money and time to fix.
Pools are supposed to be airtight, but the sealants deteriorate over time. Pools might leak through accessories, plumbing, and fittings or even via the shell. Repairing leaks helps save heat, water, and chemicals. It also aids in preserving the structural components of the pool.
Leak detection is a specialized service that is undertaken only by professionals. However, some problems are minor thus the owner can fix them quickly. If you suspect a leak, go through these aspects before hiring a service provider.
Does the pool leak all the time?
If it does, look out for tears in the vinyl or cracks in the plaster. Look carefully at the inside of the skimmer and the tile line. The most common problem in the case is usually a separation between the concrete and the skimmer. The issue can be fixed easily using pool putty. The moment you notice a line of weakness, test using a dye. Apply the dye at the crack with still water in the pool, then examine whether the color is sucked into the crack or not.
Does the pool leak only when the equipment is on?
If yes, it could be an indication of a pressure-side return leak. When the filter pump is on, the plumbing on the pressure side is under a lot of pressure. It might open up small drips into the spurting gushers. Check the backwash and waste line to ensure that the water is flowing consistently. An inch of pool water may total to about 500 gallons. Look out for wet spots in the yard.
Does the pool leak only when equipment is turned off?
If it is the case, it might be an indication of a suction side leak or a leakage in the pipes that draw water from the pool. When the filter pump is working, a vacuum is created in the plumbing at the suction side. Therefore, air could be drawn into the leaking voids. You can tell this when you notice air buildup in the tank or air in the pump basket if the lid is clear.
Does the water stabilize at any given level?
To ascertain this, you should first test the skimmer. You will do so by closing the skimmer valve and allowing water to drop below the skimmer level. In case the water levels keep dropping, you can rule out the possibility of a faulty skimmer.
Once the skimmer is out of the picture, you ought to test for other possibilities. Do this by allowing the water to stabilize at any level and then dye testing. Inspect around the pool carefully at that level. Look out for debris that might have been sucked into the crack. You can never miss detecting a leak when using this technique.
