Dye + acoustic methods
Leak detection surveys
Detection is a process of elimination run in a deliberate order. A bucket test first separates genuine loss from evaporation. Isolation tests then split the loss between shell and plumbing. Dye testing traces flow paths at suspect points (skimmer box throats, return fittings, light niches, steps) while acoustic listening picks up escaping water behind the shell that no dye will reach.
Scope
What this covers
Bucket test and measured loss-rate comparison with equipment on and off
Isolation of the shell from the plumbing to attribute the loss
Dye testing around every penetration, fitting and visible crack
Acoustic and hydrophone listening across floor and wall areas
A written findings summary locating the loss before repairs are priced
Timing
When it's needed
Book detection when top-ups exceed the seasonal norm, when the auto-fill runs constantly, when the pump loses prime overnight, or when damp patches and unusually green grass appear near the pool. Chemical consumption creeping upward is the same story told a different way, replacement water dilutes everything.
Never fully drain a pool without a groundwater and hydrostatic assessment, shells can lift out of the ground under external water pressure. Isolate power at the switchboard before anyone touches a pool light or its niche, and keep children away from partially drained pools and open excavations during repairs.
Quote variables
What shapes the scope
Pool construction and finish, which set the applicable detection methods
Whether loss occurs with equipment running, idle, or both
Number of penetrations (lights, jets, skimmers, solar returns) to be cleared
Access to pipe runs between pool, filtration pad and any water features
Pool repairs cross several licensed trades in NSW: plumbing work on pool pipework requires a licensed plumber, electrical work at lights and equipment requires a licensed electrician, and structural or building work above prescribed values requires an appropriately licensed contractor under NSW Fair Trading rules. Ask which licence covers each part of your quote and verify it before work begins.
