Leak Detection and Water Loss
Measure actual loss first, then isolate whether the water is leaving through evaporation, equipment, or underground plumbing.

Establish whether it is a real leak
Many owners start digging mentally before they have even measured the loss.
Compare pump-on and pump-off behavior
This simple split can narrow the problem dramatically.
Inspect the obvious locations
Equipment-pad leaks are cheaper and more common than buried-plumbing fantasies.
Isolate sections before calling for pressure testing
Isolation saves time and money when you need a pro.
Know when to escalate
Pressure testing and advanced leak detection make sense once the simple steps point to a real buried or structural problem.

Owner vs pro boundaries
Use the escalation guide when water-loss work starts moving toward pressure testing, structural assessment, or unsafe excavation assumptions.
Leak Work Boundary
Owner-safe leak work is mostly measurement and visual isolation. Once the task becomes invasive, the cost of being wrong rises quickly.
- ✓ Mark the waterline, run a bucket test, compare pump-on and pump-off loss, and inspect obvious equipment-pad leaks.
- ✓ Use dye testing around accessible fittings, skimmers, and visible cracks when the procedure is straightforward.
- ✓ Document valve positions, measurements, and photos before calling a leak-detection specialist.
- ★ Pressure-test underground plumbing, isolate buried lines, or excavate deck and yard areas.
- ★ Diagnose shell movement, structural cracks, or hidden plumbing failures under decking and hardscape.
- ★ Interpret advanced leak-detection equipment, sonic tools, or hydrostatic-relief interactions.
- ⚠ The water loss is severe enough to threaten pump prime, skimmer operation, or heater flow.
- ⚠ Soil is washing out, decking is moving, or cracks suggest shell or plumbing movement.
- ⚠ You are about to dig, pressure-test, or force valves without a defined leak-isolation plan.
