Abstract
A reel for installing electrical wiring through the water circulation line of a swimming pool comprising a central housing and a tubular junction fitted to the housing. A spool of line is contained within a watertight chamber defined by the central housing. The other end of the tubular junction is fitted to a hole drilled in the water circulation line of a pool, and water from the circulation line is allowed to fill the chamber of the reel. The spool floats freely within the chamber as line unwinds from it and passes through the tubular junction to the water circulation line and out into the pool. Electrical wiring is then fastened to the end of the line and pulled back through the water circulation line.
