when heating valve for sweat connec-
tions to avoid damaging internal rubber
and plastic components in valve.
1. Install rough piping and valve body as shown.
Do not use PEX or CPVC CTS piping from
valve to tub spout, as the reduced ID re-
sults in too much back pressure for valve
to function properly. When facing valve, HOT
“H” is on left and COLD “C” is on right. Tub
port “T” should face down and shower port “S”
should face upward. The ears on the valve at
the 5 o’clock and 11 o’clock positions may be
used to attach the valve to framing of wall if
necessary.
