Repair a Leak in the Internal Piping (Shower, Enclosed Unit System and Early Production
Containerized Shower only)
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.
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.
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. Ensure circuit breaker No. 2/4/6 is set to the OFF position, the water supply has been disconnected
and all pressure relieved from system. Ensure water system has been completely drained before
2. Unsolder the damaged or leaking joints by applying a torch to the pipe (1) adjacent to the fitting (2).
Heated pipe, fittings, and solder are capable of producing serious burns. Wear heat
resistant gloves, and always use pliers to handle work being soldered and unsoldered.
Failure to observe safety precautions may result in serious injury to personnel.
3. When solder is shiny and fluid, use pliers to remove pipe (1) from fitting (2).
4. Allow pipe to cool.
5. Use sandpaper to clean pipe and fitting to be joined.
6. Apply flux to pipe and fitting at joints
7. Join pipe (1) and fitting (2).
8. Apply heat to fitting (2) with torch.
