Before You Begin (cont.)
NOTICE: Use only 1/2" (5/8" OD) copper pipe (type L or M)
between the valve and bath spout. Using other materials may cause
back pressure and result in water flowing from the showerhead and
bath spout at the same time.
NOTICE: Do not force the handle in any direction. Forcing the
handle will damage the valve.
Observe all local plumbing and building codes.
Shut off the main water supply.
