Fixture Isolation Dome

Isolate pool fixtures to check for leaks using dye with this device. When pressed against the pool wall the one-piece, flexible silicone dome covers the fixture and forms a watertight seal agaiuns the wall. A small stream of dye can be squirted at the opening of the attached clear tube to watch for movement. If there is a leak behind the dome, the suction from the water loss will cause dye to be drawn into the dome. Great for lights, main drains, and any other fixtures that can be isolated. The dome is approximately 12" wide and will cover many residential pool lights, but is too small for typical vinyl liner pool lights.
