Pressure testing

Pipework pressure testing

Buried plumbing fails invisibly: a glue joint lets go under a path, tree roots crush a flexible line, or ground movement shears a pipe at the shell penetration. Pressure testing plugs and pressurises each circuit separately (skimmer line, main drain, returns, solar loop, the balance line to any spa) and watches the gauge. A circuit that will not hold pressure has a fault; the rate of decay hints at its size.

Scope

What this covers

  • Individual isolation and testing of every accessible circuit

  • Gauge-monitored hold tests with results recorded per line

  • Induction of air or tracer where a failed line needs pinpointing along its run

  • Marking of the indicated dig point to keep excavation surgical

  • Advice on rerouting versus repair where a line has failed repeatedly

Timing

When it's needed

Ordered when isolation testing shows the shell holds but the system loses water with equipment running, or when a spa drains to a mysterious level overnight, which classically implicates the balance line or its check valves rather than the spa shell itself.

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 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.
