    I assume that you are talking about the Horseshoe clip taht hold the cartridge in place.

    When you removed the old cartridge did it remove easily and cleanly or did it seperate some of the rubber pieces that go over the waterways of the catridge.

    The valve must be cleared of all debri and must seat all the way in.

    Also, once in place it may be neccessary to turn the cartridge back and forth slightly until the retaining clip is completely lined up with the slots.

    Once you have installed the cartridge and if the hot & cold waters are reversed it is not neccessary to remove the cartridge instead just take hold of the brass part of teh cartridge and rotate 180 degrees and that will reverse the hot & cold water.

    Good luck1

    Hope I have been of assistance.

    What is the model number for the shower body?

    Make sure the valve is seated all the way and is aligned properly, it should slide in with no problems. Diagram.

Make sure that the stem is slightly pulled out or open then use the plastic insertion tool that comes with the new cartridge and a pair of pliers to push cart. all the way in. Try the retaining clip again. If still won't go, partially install the insertion tool and turn cart. back and forth til clip goes in. Hope this helps

Moen 1225 Cartridge for kitchen faucet

I have no experience with modern quarter-turn taps as I prefer the ease and economy of traditional tap washers. I do have lots of experience with O rings of various types.

Most commonly O ring breakage is due to the wrong size being used - diameter and/or section. when machined metal parts are fitted together and sealed with an O ring the clearance between the parts is very small - just enough to allow a sliding fit. The O ring(s) generally locate in a groove, sometimes on the end face but mostly around the diameter.

O ring sizes are chosen to completely fill grooves on the end face without either stretching or compressing the rubber. Grooves around the diameter require similar consideration though some stretching is needed to assemble them; once fitted the rubber should not be under either tension or compression. The chosen section of the ring will allow the groove to be filled when the components are fitted together therefore when they are separated it will seem the O ring is too thin for the groove. If the correct size is used with carefully machined components and suitable lubrication applied during assembly there should be no difficulty.

O rings are available in a number of different materials from soft natural rubbers to fairly hard synthetic materials.

I suggest you carefully measure the components and compare your results with the supplied O rings.

Cannot remove moen sink cartridge removed retaining clip but cannot pull or unscrew cartridge

MOEN cartridges can be EXTREMELY difficult to remove sometimes. Be sure the horse shoe clip is out. Then you can use a crescent wrench and carefully turn the cartridge, once you get the cartridge to turn a little you can try to pull it again. They actualy make a tool to pull these. They run around $10 at your local home improvement store. The tool takes the place of the crescent and puting the handle back on to pull it. Hope this helps.

Moen One-Handle Kitchen Faucet Leak - Hot Only

Moen uses a cartridge on their faucets. You have to remove the handle. You will find the stem and a small U shaped retainer. Pull the retainer out and pull the cargridge straight up. Sometimes the cartridge is in there pretty tight and you have to pull hard. Once you do this, take the cartridge to your local hardware store. Replace it with the one you have because they have 2 different one. Install it back in the same order it was removed. Hope this helps and good luck.

Repair cartridge in Moen Monticello single handle lavatory faucet

After some additional experimenting, contrary to information I was previously able to gather, I discovered that the white plastic retainer doesn't (in this type of Moen faucet) actually screw off but rather is held in place by a spring clip inserted from the rear of the retainer (toward the wall side of the basing). Simply sticking a small screwdriver in the opening (approx. 45 degrees downward) and tipping the screwdriver toward the front of the faucet, snaps the spring clip out through the opening.
The plastic retainer than lifts off. Note: the flat sides on the retainer suggest that a wrench will be needed but such is not the case.
