What Plumbers Do to Detect Leaks

Plumbers use various methods to detect leaks in homes. One common technique is the "Listen Test". When you turn off the main water shut-off valve, locate the hot and cold water shut-offs for your kitchen and bathroom sinks. Open both faucets simultaneously while running a warm bath or shower.

Visual Inspection

Plumbers perform a visual inspection of the pipes and fixtures for signs of leaks. They look for any water spots, stains, or mineral deposits on walls, ceilings, and floors.

Pressure Test

Plumbers use a pressure test to detect leaks in pipes. They attach a pressure meter to the pipe and turn on the water supply, then measure the pressure before and after.
