1225 Cartridge: Moentrol with Integrated Transfer Valve
This article will provide step-by-step instructions on how to replace a 1225 cartridge in a 3320, 3330 and 3350 Moentrol
with an Integrated Transfer Valve shower system. In this two handle shower system, the 1225 cartridge is located
behind the lower handle and controls the flow and temperature of the water.
Preparation:
•The water supply shut off valves must be turned off- see article How to Turn Off the Water Supply to the
Faucet.
• Recommended Tools: Phillips Screwdriver & Pliers
• The following instructions assume the handle and associated handle pieces have been removed. For additional
details, visit Vertical Spa: Moentrol with Integrated Transfer Valve and select the type you are repairing. The
faucet guide will contain specific information on handle assemblies associated with that style of product.
• We recommend covering the drain before beginning so to not loose any parts down the drain.

2. Slide off the escutcheon plate (#5A).
3. Grab ahold of the stop tube (#6A) and pull it forward until it has been
removed.
4. Lift the tab at the top of the U-shaped copper colored retaining clip
(#7A) just enough to grab it with your hand to fully remove. Be
careful not to drop the clip (#7A) behind the wall.
5. Using the plastic twisting tool (see Image A below) provided in the
1225 cartridge kit (#8A), rotate the cartridge (#8A) 1/4 of a turn (90
degrees) in either direction. This will help loosen the cartridge (#8A).
Remove the twisting tool from the top of the cartridge (#8A). Pullout the
stem of the cartridge (#8A) until it stops. Using pliers, grab the stem of
the cartridge (#8A) and pull the cartridge (#8A) out. This may require
some effort. If you are replacing the 92451 service kit, see 92451
Cartridge Service Kit Repair Guide for additional details.Note: It is
highly recommended to clean and flush the valve body (#9A)
before installing the new cartridge (#8A). See Valve Body Cleaning

plastic
tabs on
the
cartridge
(#8A)
must be
centered
on the

the valve
body
(#9A),
which are
located at
the 12 and
6 o'clock
positions.
2. Gently slide the
copper clip (#7A)
back into the brass
valve body (#9A)
on top of the
cartridge (#8A). If
you encounter any
resistance, do not
force the copper
clip (#7A). The
cartridge (#8A)
may not be
properly aligned
(see step 1). If for
any reason the
copper clip (#7A)
cannot be
installed, the
water cannot be
turned back on to
the shower
system until the
copper clip (#7A)
is replaced.

3. Rotate
the stem of the
cartridge (#8A)
so the small
notch is facing
down. The notch
on the stem of
the cartridge
(#2) determines
the hot and cold
location. If the
hot and cold are
reversed, rotate
the stem of the
cartridge (#8A)
180 degrees.
4. Slide the stop tube (#6A) back
onto the valve body (#9A).
5. Position the escutcheon plate
(#5A) with the word "Moen" upright
and slide it onto the valve body
(#9A).
6. Position the upper mounting cup
(#2A) so the screw holes lines up
with the screw holes on the valve
body (#9A). While holding the
upper mounting cup (#2A) in
position, use a phillips screwdriver
to thread the upper mounting cup
screws (#1A) clockwise until tight.
Repeat this step with the lower
mounting cup (#4A) and lower
mounting cup screws (#3A).
