Abstract
A method of installing a pool purifier is provided in which an existing water pipe in communication with the pool is used as a conduit for an electrical wire. The wire connects the pool purifier to a source of electricity located outside the pool to energize the pool purifier. A reel for installing the electrical wire through the water circulation line is also provided. The reel comprises a central housing and a tubular junction fitted to the housing. A spool of line is contained within a water tight 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. The electrical wire is then fastened to the end of the line and pulled back through the water circulation line.
