Install Support Framing (cont.)
NOTE: When installing the K-2975 or K-2976 valve, use 3/4"
nominal copper tubing and fittings throughout this installation.
Smaller diameter piping upstream or downstream of the valve will
reduce performance of the valve.
Determine the desired location for the valve according to the
roughing-in information, and construct suitable stud and support
framing for your configuration and valve.
If the finished wall is drywall, 1/2" (1.3 cm) drywall or thicker
should be used or the finished wall will not be strong enough.
Determine the finished wall thickness. The finished wall should
not extend beyond the outside edge of the plaster guard. The
valve can be mounted with the plaster guard flush with the
finished wall for maximum wall thickness. If the plaster guard is
recessed, the finished wall is too thick. Refer to the diagram
above.
Install water hammer arrestors in the hot and cold water supply
lines.
Determine the desired location for the valve according to the
roughing-in information, and construct suitable stud and support
framing.
