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

and Flushing for additional details.

body

(#9A). The

plastic

tabs on

the

cartridge

(#8A)

must be

centered

on the

slots on

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).
