Prove the loss under stable conditions with a bucket test and 24-hour measurement before calling a leak specialist.
- ✕Do not call for pressure testing before confirming the loss is real with a bucket test
- ✕Do not start digging or excavation before the leak specialist has pressure-tested
- ✕Do not pressure-test buried lines before isolating equipment-pad leaks first
24-hour water level drop / Valve map and zone isolation results
Pressure Testing Handoff
Prepare the measurements, photos, valve map, and isolation notes a leak specialist needs before pressure testing begins.
Prove the loss under stable conditions
The handoff starts with a real number, not a feeling that the level is lower.
Capture the pad and visible hydraulics
The leak tech needs the equipment context before any line is pressure-tested.
Isolate likely zones one at a time
Zone isolation narrows the work before the specialist brings pressure equipment.
- Write the result of each isolation test immediately so the sequence is still trustworthy when the specialist arrives.
Package the visit
Give the tech the facts they would otherwise spend a visit collecting.
Know the stop conditions
The handoff ends when the work would cross into invasive or unsafe territory.

Leak detection and water loss
Use the broader leak workflow when you still need to prove whether the loss is real before a pressure test is worth it.
Owner vs pro boundaries
Use the escalation guide when the next step would move from documentation into invasive testing or excavation.
Pumps and hydraulics
Use the hydraulic guide when pump-on versus pump-off behavior is part of the leak isolation work.
Equipment pad labeling and handoff
Use the pad-labeling guide to build the valve map and shutdown notes that make leak visits cheaper.
Water loss decision tree
Use the decision tree when you still need to classify the loss before pressure testing is worth it.
Pressure Test Boundary
Owner-safe leak work is evidence gathering. Pressure testing buried plumbing or chasing hidden structural failures belongs to the specialist when the simple checks are exhausted.
- ✓ Measure water loss, compare pump-on and pump-off behavior, and photograph the pad and visible plumbing.
- ✓ Label valves, record the current filter pressure, and keep the measurement sequence organized for the visit.
- ✓ Disable obvious masking factors like autofill when you are trying to understand the actual loss pattern.
- ★ Pressure-test buried plumbing, isolate hidden lines under decking, or excavate to chase underground failures.
- ★ Use sonic, hydrostatic, or other advanced leak-detection equipment when the simple owner-safe checks are exhausted.
- ★ Decide whether structural movement, shell cracks, or hidden plumbing under hardscape needs specialist repair.
- ⚠ Water loss is threatening pump prime, skimmer operation, or heater flow.
- ⚠ Soil is washing out, decking is moving, or the next step would be blind digging.
- ⚠ You are about to open live electrical equipment or pressure-test without a defined isolation plan.
