Pressure Testing & Plumbing Line Inspection

Pressure testing is the definitive diagnostic method for determining whether underground or in-wall pool plumbing is the source of water loss in a Canoga Park swimming pool. The process involves capping each plumbing line at the pool wall and at the equipment pad, then pressurizing each circuit independently with air or water and monitoring the gauge for pressure drop over a measured time interval. A stable gauge reading confirms the line is intact; a dropping reading confirms a breach somewhere in that circuit. Joseph's Canoga Park Pool Repair & Replaster performs systematic pressure testing as either a standalone service or as part of a comprehensive leak detection call.

Pressure testing is particularly valuable when water loss continues even after visible cracks and equipment pad leaks have been repaired — it confirms whether the remaining loss is attributable to underground plumbing and exactly which circuit is involved, preventing unnecessary excavation of sound pipes. We test return lines, main suction lines, main drain lines, cleaner lines, and spa jets separately to give you a complete circuit-by-circuit picture of your plumbing system's integrity. Each test result is documented and provided to you in writing along with a clear explanation of what it means for your repair scope and budget.

If a line fails the pressure test and physical repair or replacement is recommended, we transition immediately to repair planning rather than requiring a second appointment. Our goal is to give Canoga Park homeowners a complete, actionable answer in a single visit whenever possible.
