Installation Instructions
PART# 18.30.061
SHOWER ONLY VALVE
(ALSO USE FOR 78.30.061)
This valve is precision engineered to provide satisfactory performance provided it is installed and operated in accordance
with recommendations contained in these instructions. Please be sure to familiarize yourself with these instructions.
NOTICE: These instructions do not represent step-by-
step directions. They are a product supplement only
to be used by a qualified and licensed plumber.
We recommend all plumbing fixtures be installed
by a professional.
PRIOR TO STARTING:
1. FLUSH lines of debris prior to starting. Debris may clog cartridge.
2. The mud guard represents a typical hole size required to access the integral service stops and the removable
cartridge. The rough valve comes PRE-ASSEMBLED and FACTORY READY TO INSTALL.
3. Be alert that the valve body is not installed upside down. See markings on BACK of valve.
4. The screwdriver service stops should always be in the full-open position with the valve in use. They are not to be used
to restrict flow of either hot or cold inlets. THE HOT AND COLD WATER MUST BE FULLY OPERATIONAL AT THE VALVE INLETS
OR THE UNIT WILL NOT FUNCTION PROPERLY DURING TESTING OR EVEN FLUSHING.
5. When soldering the valve body, it is NOT necessary to remove the cartridge assembly.
6. Shower valve (Part # 18.30.061 or Part # 78.30.061) may be used for shower only or tub only. The unused port
must be capped by plumber during installation.
7. Make sure to flush or raise grouting on a tiled wall surface to prevent seepage behind plate.
ROUGH-IN OF VALVE
1. Rough valve body into wall, connecting piping to 1/2" Female
copper sockets or 1/2" Male I.P. nipples. NOTE "UP AND DOWN" MARKINGS ON BACK OF VALVE.
2. The depth of rough-in should account for thickness of wall materials to be used, combining thickness of wall board
and finished wall materials. It is CRITICAL TO PLACE MUD GUARD FLUSH WITH FINISHED WALL. FIG. 1
3. Anchor installation to bracing between studs. (Ears on the valve body can be used by removing the plastic guard OR by
anchoring the connection piping.)
4. Valve should be pressurized and tested for leaks at the connections.
DO NOT close wall until valve is tested.
5. Mud guard should be left attached to the valve until the finished
wall material is installed.
6. Use only propane or butane gas when soldering. Do not use
oxygen / acetylene as extreme heat may damage internal
components. Do not solder within 4 inches of valve port. Open
stop valves when soldering inlets.
7. FOR TUB/SHOWER INSTALLATIONS: 36" must be allowed between
valve and showerhead to prevent stacking. If PEX is utilized, the
supply line must be oversized to 3/4" for full flow capacity.
