The Number One Reason for In-Ground Pool Leaks

Finding Leaks

• There are a number of ways to track down a leak within the pool or in the plumbing. Most can be accomplished without the aid of a professional and materials are available from a pool specialty retailer. A pressure test will help identify leaks in the plumbing or pool structure. This is one process where the help of a professional is preferred, as it requires use of a specialized pressure tester. This test is applied to the whole system if a structural leak is suspected, or to a targeted area of the plumbing to narrow down a source. Sonic location will locate a leak create a bubbling sound, the result of air escaping the leak. A dye test requires a few drops of food coloring be applied to an area where a leak is suspected. If the dye is pulled out of the water, it is evidence of a leak. This is most effective for structural cracks, or leaks around lighting or other fittings. Vinyl liners are prone to leaks, and visual inspection is one way to track and repair the problem. Modern electronic vinyl leak detectors are a relatively new option which will locate any sized tear in vinyl lining much more quickly than looking by hand.

Fittings and Accessories

• Swimming pools are designed to be watertight, but associated sealants and accessories will begin to break down and wear out long before the pool itself. Any plumbing piece or accessories- - including light fixtures, hoses, drains filters and pool cleaners- - are a potential source of leaking and are the primary cause of water loss, particularly in older swimming pools. Pool owners should spend time resealing each of these devices with an appropriate water proof sealant. These products, which will vary depending on the specific use and location of the device, are available from most pool specialty or home improvement stores.

Cracks

• Cracks, primarily in the body of the pool, are another source of leaking. Cracks within the pool plaster itself are fairly uncommon, but have the potential to cause serious problems. This is a condition which is most present in very old swimming pools, or those located in poorly filled soil or an area prone to earthquakes and other disasters. The treatment for such a problem varies depending on the severity of the damage and the cause of the cracks. Aging swimming pools might require full replacement or simply a new coat of plaster, while back filling problems will need to be addressed by a landscaping professional.

Evaporation

• Water evaporation, though not technically a leak, is responsible for large amounts of water loss in a swimming pool. This process has the potential to remove several hundred gallons of water from a pool each month, which could severely affect water bills. The surface are of the pool, air and water temperature, humidity and wind are all factors which contribute to water loss from evaporation. The larger a swimming pool, the larger the surface area and the more water will be lost. Evaporation rates increase dramatically during warmer months, as evaporation is more prevalent when the difference between air and water temperature is greatest. Covering the pool with a cover when not in use is the best way to prevent or reduce evaporation.
