The handle must be removed to allow access to the retainer clip, then the cartridge pulls out. You may need a cartridge puller if the faucet is old.
No. Moen cartridges pull right out with a pair of channel locks after you pull the retaining ring out. Turn the water supplies off first
YES, you can use moen 1225 as a replacement cartridge. It works perfect. Sad so hard to find an honest plumber.
The inside part of a Moen faucet / shower body
Yes, you can replace cartridge on any Moen unit
Did you flush out the valve body prior to installing the new cartridge
You can go to Moens website for directions. Instead of cleaning the cartridge, you can take it to a Plumbing or Hardware store and they will replace it for FREE. Moen cartridges are guaranteed for life and the stores CANNOT charge for them as they return them and get another one for free from Moen!!!
According to Moen, there is NO difference between the 1225 and 1225B cartridges. They used to come in different packaging but now even that is the same.
Shut the water supplies off, take the handle off, unscrew the cartridge. The washer will be on the bottom of the stem of the cartridge
if it is a single lever faucet the cartridge needs to be replaced. check the supply valve under the sink first,
The only way to be certain is to remove the bullet with a bullet puller, empty out the powder, and weigh it.
See if the valve has integral stops. These will usually be between the cartridge and the inlets of the water. When you have the cartridge out, open each stop slowly to purge any sediment out. This will also tell you if there is water pressure to that point of the faucet. Don't stand directly in front of it and get soaked, I don't want you blaming me! lol
