Leak Detection & Repair

Pressure Clean Pools is fully equipped to detect leaks in your pool with state of the art Sonic Leak Detection equipment.

Your pool will naturally lose some water to evaporation, some to splash-out and some to backwashing. You may also gain water from rainfall. A good rule of thumb is that if you’re routinely adding more than two inches of water to your pool per week, you may have a leak.  A leak is worth spending some time and money to repair. Too much money can be wasted to continually adding chemicals and more water to the pool.

Pools are meant to be watertight but sealants will deteriorate over time. Other parts of your pool shift and settle, or just plain wear out.  Pools can leak through any of the fittings or accessories, plumbing or even right through the shell.  It is important to repair leaks, not only to save water, heat and chemicals, but also to prevent undermining pool structural components, and washing away fill dirt.

If you suspect a leak, look at the following things and then Contact Us for service:

1. Is the pool leaking only with the equipment on? With the filter pump on, the plumbing on the pressure side is…. Under pressure. This can open small drips into the spraying gushers. One inch of you pool water can equal 500 gallons.

2. Is the pool leaking only with the equipment off? With the filter pump on, the plumbing on the suction side is under vacuum; air can be drawn in through otherwise leaking voids.

3. Does the pool leak all the time? This does not rule out leaks in the plumbing, but turns a suspicious eye on the shell of the pool, generally indicating cracks in the plaster or tears in the vinyl.

4. Are there leaks at the equipment pad? Look closely at the filter, pump, heater and valves.  Check the ground for moisture. Turn the pump on and off, looking closing for spraying water when the pump is turned off.

5. Does the water seem to stabilize at any level? You may be able to close the skimmer valve and allow the water level to drop below the skimmer.  If it keeps going, we can rule out the skimmer (although there can always be more than one leak.) The underwater light is a common leak source.

6. Are there any wet areas around the pool? Take a walk around the pool’s edge, and between the pool and the equipment pad.  Check for wet soil and eroded areas.

7. Is your pool a vinyl liner? If so, there are special considerations. Look for sinkholes where sand under the liner may have washed away. Look for tears or separations around all fittings: skimmer, returns, cleaner line, etc. Does the liner balloon out anywhere or feel squishy to-the-touch?  Pay close attention to steps and corners, where the liner may be stretched more than normal.  If an animal had the misfortunate to fall in your pool, you may notice claw marks (tears) just below the water line. When liners become old, they may have many pinhole leaks. There can always be more than one leak.

8. Unsure of your water loss and evaporation rate? For help with leak detection, try this simple test.

9. Place a bucket of water beside the pool and mark both the water line in the bucket and the water line in the pool.  Run the pump, and after 24 hours, check the loss of both.  Refill the pool, and repeat the test for 24 hours with the pump off.  Have both measurements ready, and call us with your results.

**Many pools leak in more than one area, so monitoring is important after any repair is made.**
