We isolate and pressure test pool plumbing lines to determine whether water loss is coming from underground pipework—before pavers or concrete are disturbed.
Each accessible line is isolated, placed under controlled test pressure and monitored. A pressure loss helps identify the affected circuit and separates a plumbing fault from shell, fitting or equipment leaks.
This narrows the repair area and reduces unnecessary excavation based on guesswork.
Review the equipment, pool layout and reported water loss.
Plug and separate accessible plumbing circuits.
Test each line and monitor it for pressure loss.
Explain the affected line and appropriate next step.
