Pool & Spa Leak Detection in Torrance, CA
Topping off your pool every few days? A pool losing more than a quarter-inch a day beyond normal evaporation almost always has a leak in the shell, plumbing, or equipment pad — and we can tell you exactly which.
The Bucket Test: A Quick First Check
Before scheduling a full inspection, you can get a rough read on whether you have a real leak. Fill a bucket with pool water and set it on a step in the pool so the water levels match. Mark both water lines — the bucket’s and the pool’s — and check again in 24 hours.
If the pool’s water level drops noticeably more than the bucket’s, evaporation isn’t your problem — you likely have an actual leak somewhere in the shell, the plumbing running to and from the equipment pad, or a fitting.
Where Pool Leaks Usually Happen
The Shell or Liner
Cracks in gunite or plaster, or tears in a vinyl liner, let water escape directly through the pool’s structure — often at fittings, lights, or skimmer throats.
Underground Plumbing
The pipes running between the pool and the equipment pad are buried and pressurized whenever the pump runs, making them a common but hard-to-see leak source.
Equipment Pad
Pump seals, filter O-rings, and heater fittings wear out over time and can leak water that never even reaches the pool itself.
How We Find a Pool Leak
- Confirm real water loss with a controlled bucket test and visual inspection
- Pressure test the plumbing lines running to and from the equipment pad
- Dye test suspect areas — skimmers, lights, fittings, and cracks — to visually confirm water movement
- Check the equipment pad itself for pump, filter, and heater leaks that never reach the pool
- Provide a clear diagnosis and repair recommendation before any work begins
Frequently Asked Questions
How much water loss is normal from evaporation?
In Southern California’s warm, dry climate, a quarter-inch to half-inch of evaporation per day is typical, more during hot or windy stretches. Consistent loss beyond that, confirmed with a bucket test, usually points to an actual leak.
How much does pool leak detection cost?
Typically $300 to $600 depending on the pool’s size and how many potential leak points need testing.
Can a small pool leak really cause a big problem?
Yes. Beyond wasted water, a leak in underground plumbing can erode soil beneath the pool deck or nearby foundation over time, and it’s usually far cheaper to fix early than after prolonged undermining.
Do you test spas and hot tubs too?
Yes, the same pressure-testing and dye-testing approach applies to spa plumbing and shells, whether it’s a standalone spa or one attached to a pool system.
Will you need to drain my pool to find the leak?
Not always. Many leaks can be located and diagnosed with the pool full using pressure testing and dye testing. Draining is sometimes necessary only for direct visual inspection of certain shell repairs.
