REPLACE
Replace a Damaged Shutoff Valve (Shower, Enclosed Unit System and Early Production
Containerized Shower only)
WARNING
Repair of plumbing requires the use of tools in restricted spaces. Slipping wrenches can
cause serious injury.
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.
NOTE
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.
NOTE
The water system must be thoroughly drained before proceeding. The unsoldering
procedure will not work on pipes with water inside. If necessary, blow compressed air
through the system to remove remaining water.
1. Disconnect union (1) and drain water.
2. Remove valve handle nut and valve handle (2).
3. Remove valve packing nut.
4. Remove valve stem (3).
WARNING
Soldering and unsoldering require the use of an open flame, which can burn skin and
eyes. Keep open flame away from combustible materials. Failure to observe safety
precautions may result in fire or serious injury to personnel.
5. Unsolder damaged or leaking joints by applying a torch to the pipe (4) adjacent to the valve (5).
