Replace a Shower Valve (Shower, Enclosed Unit System and Early Production Containerized
Always use two pipe wrenches when tightening or loosening a pipe union. Use one pipe
wrench to turn the larger union ring, and another to secure the pipe attachment. Failure
to do so can twist the union on the pipe, damaging both.
The Shower, Enclosed Unit, System and early production Containerized Showers use
copper piping for the internal water lines. Later production Containerized Showers have
been improved to ease field repair, and are fitted with flexible plastic hoses secured with
hose clamps. Ensure that you know which model you have before proceeding.

2. Remove the shave stand water connection cover (1) on the side requiring replacement.
3. Loosen the two unions (2) on each end of the plumbing (four total).
