Replace Mixer Valve (Early Production Containerized Shower only)
NOTE
Early production Containerized Showers have the mixer valve connected by unions into
copper pipes. Later production Containerized Showers are connected by flexible plastic
hoses. Ensure that you know which model you have before proceeding.
1. Ensure circuit breaker No. 2/4/6 is set to the OFF position and that water is turned OFF at pump, and
all pressure had been relieved from the system.
CAUTION
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.
2. Using a pipe wrench, loosen three unions (1, 2).
NOTE
Some Containerized Showers mount the mixer valve to pipe hangers.
3. Remove bolts (3) securing mixer valve (4) to mount (5).

5. Remove mixer valve.
6. Remove discharge union (1) from mixer valve.
7. Install discharge union on new mixer valve.
8. Remove stop valves (7) from mixer valve plumbing.
