TL;DR
A soap-bubble leak test is the application of a leak-detection solution to pressurized gas piping joints, fittings, and valve connections, where escaping gas blows visible bubbles. Technicians use it after installing appliances, replacing a gas valve, or pressure-testing a line, brushing the solution on every disturbed joint; commercial fluids are preferred since some dish soaps corrode brass.
What it means
A soap-bubble leak test is the application of a leak-detection solution to pressurized gas piping joints, fittings, and valve connections, where escaping gas blows visible bubbles. Technicians use it after installing appliances, replacing a gas valve, or pressure-testing a line, brushing the solution on every disturbed joint; commercial fluids are preferred since some dish soaps corrode brass. It finds leaks too small to smell, and any bubbling joint gets remade, not just snugged.
