Why Is Replaced Moen 1222 Cartridge Leaking?
Your replaced Moen 1222 Cartridge could be leaking again for quite a few reasons. We can name a few very common ones-
First of all, it can be a possibility that the reinstalled Moen 1222 Cartridge is faulty too. This might cause the leak.
Corrosive Brass Body
Calcium and other minerals in the water are responsible for making it corrosive. Water can chip away at flaws in the brass body of the faucet over time.
Brass may wear away at little bumps and soft areas. This enables the formation of rivulets in the brass. It’s ideal to use abrasive cleaners to wash the body.
A ceramic, brass, or rubber seat may be installed in the faucet to seal the cartridge hole. With usage, the seal can get damaged to the point that allows water to leak.
It’s also possible that the O-ring will fracture and produce a leak. It’s best if you replace the elements inside the faucet alongside for the o-ring to seal properly.
Solution for Moen 1222 Cartridge Leaking Again
As stated before, if the Moen 1222 cartridge is leaking, replace all the elements at once as needed. The good thing is Moen gives a lifetime guarantee. If you contact them, they’ll send you a free replacement.
Now, let’s get into the step-by-step process of replacing the Moen 1222 cartridge-
Step 1: Take Necessary Precaution
Closing the handle firmly might add to the problem. That way the valve may be harmed in the process.
You can put any cloth underneath the tub or faucet to avoid damage to the floor. This will help collect any small parts that may fall during the process.
It’s ideal to turn off the water supply before turning on the shower valve. Make sure your main shut-off valve is turned off the water.
Step 2: Unscrew the Escutcheon Plate
Pull the rubber cover off the top of the control valve with a Phillips screwdriver. Then release the screw in the knob’s center. Unscrew the two screws that attach the escutcheon plate to the wall and discard it.
If required, gently pry it open with a flat-bladed screwdriver. Keep hold not to scrape the surface.
Remember to match the screwdriver with the screws. In order to do that you can select a screwdriver from below-
Step 3: Remove the Cartridge Clip
Using pliers, remove the U-shaped cartridge retaining clip from the valve body. Remove the little spacer washer from the shaft with the retainer clip and set it aside.
Lift the stop tube straight out of the cartridge and slide it off.
Step 4: Remove the Cartridge
The replacement cartridge should come with a white plastic nut-like tool. Slip this plastic nut tool over the shaft and into the cartridge to secure it. Then, using pliers, move it back and forth to separate the cartridge from the valve body.
Loosen the nut, then grab the cartridge’s stem with pliers and yank it directly out of the valve body.
Step 5: Place the New Cartridge
Until the new replacement cartridge seats, push it directly into the valve body. Insert the plastic nut tool into the cartridge. Then align the cartridge’s ears with the valve body’s top and bottom edges.
Snap the U-shaped retention clip back into place on the valve body. The cartridge is not placed correctly in the valve body if the retention clip does not click into place properly. Adjust it with the plastic nut tool.
Step 6: Restart the Water Supply
Now restart the water supply. Install the faucet knob on the shaft for the time being. Turn on the hot water and ensure that you get hot water at the faucet. The water may take some time to heat up, so keep an eye on it.
If the water does not heat up, re-adjust the cartridge with the plastic nut tool.
Step 7: Finishing of Replacement
Reinstall the tiny spacer washer on the shaft. Reattach the stop tube to the valve body. Now, replace the escutcheon plate and tighten the two screws on it clockwise until it is secure.
Replace the plastic knob, screw it in place, and conceal the screw with the cover plate.
Before you replace the valve, clean it with sandpaper lightly on the inside of the valve body. That way, you’re ensuring you’re not placing a faulty valve.
Well, now you know how you can fix this issue. You may face such problems with Moen as well as Glacier. Knowing how to fix it will help you in this case.
