Is Your Pool
Actually Leaking?

Pools naturally lose water to evaporation — especially in the warm, dry Bay Area summers. Before calling for service, perform the "Bucket Test" to confirm if yours is a leak or just mother nature.

1
Fill a bucket with pool water and set it on the first pool step
2
Mark the water level inside the bucket and on the pool wall
3
Run the pool normally for 24 hours
4
Compare the water loss in the bucket vs. the pool

Result: If the pool loses significantly more than the bucket (over 1/4 inch per day difference), you have an active leak.

Where Leaks Happen

Underground Plumbing

Lines crack from soil movement or age.

Gunite Shell Cracks

Structural cracks let water seep through the shell.

Fittings & Returns

Gaskets or thread failures at wall penetration points.

Skimmer Bodies

Plastic bodies crack as they age and settle.

Equipment Pad

Unions, valves, and heater connections.

Spa Jet Plumbing

Higher pressure cycling leads to faster failures.

Why Bay Area
Pools Leak More

The expansive clay soil found throughout Santa Clara County is the primary culprit. Clay absorbs water and expands in winter, then contracts in the dry summer. This seasonal movement stresses underground plumbing and pool shell joints far more than stable sandy soil would. hillsides in Saratoga, Los Gatos, and Woodside are also subject to "soil creep," gradually misaligning plumbing.
