Light Leak Tester

Quickly check for pool light leaks using dye with this testing device. When pressed against the pool wall, the one-piece, flexible silicone dome covers the light and forms a water tight seal against the wall.

The dome can be pushed against the light until the "ring seat" makes firm contact with the light lens to stop any further movement of the dome. The user can then squirt a small stream of dye at the opening of the clear tube to watch for movement. If a light housing is leaking behind the dome, the suction from the water loss will cause dye to be drawn into the dome. The dome is approximately 12" wide and will cover many residential pool lights, but is too small for typical vinyl liner pool lights.
