1. Install the Support Framing

IMPORTANT! Make sure the valve is mounted at the correct depth

so it will be properly positioned when the ﬁnished wall is installed.

NOTE: Shower only conﬁguration is shown. Adjust the support as

needed for other conﬁgurations.

NOTE: Install a backer board behind the valve for installations on

2x6 studding only.

NOTE: A backer board may not ﬁt behind the valve for installations

on 2x4 studding. Support the pipes directly above and/or below the

valve. This will also provide support for the valve.

NOTE: When installing the K-2972 or K-2973 valve, use 1/2″

nominal copper tubing and ﬁttings throughout this installation.

Smaller diameter piping upstream or downstream of the valve will

reduce performance of the valve.
