Table of Contents

Replacing a Moen cartridge may seem intimidating, but with a few simple steps, it can be done quickly and easily. With the proper instructions, even those with little experience in bathroom construction projects can confidently handle this task. By following our step-by-step guide, replacing your Moen cartridge will feel like a breeze – in no time, you’ll be admiring your newly replaced fixture with pride. So don’t be discouraged – let’s make this job something to look forward to!

Preparation

  • To start off on the right foot, gather your supplies before you begin, such as a plumber’s grease, an adjustable wrench or basin wrench, and a flexible bit. Then make sure to turn off the water first by closing the shutoff valves at either end of the sink or tub before disassembling anything.

Hofen tips

  • If you need a replacement cartridge for your Moen faucet, it’s wise to choose one from the original manufacturer. This will ensure that it is properly installed and compatible with your model. You can also purchase aftermarket replacement parts from reliable second-hand suppliers if they are specifically designed for your faucet. This may be the only option for older models, as some manufacturers no longer produce matching replacement parts.

Shut off the Water

Shut off the Water

This will differ from house to house but generally involves either turning off the water main near your hot water tank or shutting off valves near the faucet.

The main point is that both hot and cold must be turned off.

Simply locate the shutoff valves on your wall or underneath the sink for bathroom fixtures. Turn these handles until they are crosswise to your pipes, and that should shut off any remaining water flow. After you have done this, double-check that there is no more water flowing! Now you’re ready to start replacing your Moen Cartridge.

Remove the Handle

Remove the Handle

Replacing a Moen cartridge can be easy, but first, remove the handle. This might sound daunting, but it can be a breeze with the right tools and knowledge!

First, identify your Moen handle type: Is it a single-handle or double-handle faucet? Then determine how to remove it. For some models, use an Allen wrench to loosen the set screw at the base of the handle.

On other models, unscrew the hex nut on top of the handle with a wrench or use an adapter kit for hard-to-reach locations.

Once you’ve got that part figured out, turn off the water supply shutoff valves and switch your faucet from hot to cold several times before unscrewing so you don’t get a surprise when you go to open your sink later (now would also be an excellent time to put down some towels).

Remove the Faucet Clip

Remove the Faucet Clip
  • Firstly, grab a pair of pliers and clamp down on the tip of the clip. You should press firmly towards the base of the faucet so that your grip is secure and it would come off quickly without breaking.
  • Secondly, examine carefully where precisely the portion of the clip connects to the sink base, which would look like slits or notches. Now insert one end of your flathead screwdriver into one slit. Make sure you do this gently to avoid any scratches and breakage on the surface!
  • Then rotate this slightly clockwise until it pops open with ease… Et voila! This magical technique should work for various types of models, including rubber washer-style clips, wire cone clips, and C-clips。

Extract the Cartridge

Extract the Cartridge
  • If you try to extract the cartridge with pliers, it is possible but difficult. Utilizing a cartridge puller would make this process much more straightforward and efficient.
  • Connect the cartridge puller to the end of your cartridge, and screw its center into the hollow threaded area at the stem’s conclusion. Make sure you fit it tightly within a slot on the branch.
  • Now, rotate the puller left and right multiple times to unstuck the cartridge. After that, withdraw the tool to remove it altogether. It could come out at once, or you may have to keep turning and pulling until it eventually comes off.

Replace the Cartridge

Replace the Cartridge
  1. To ensure a secure fit, apply a tiny amount of plumber’s grease to the rubber o-rings on your new cartridge before inserting and aligning it into the faucet body. Be sure to line up accurately – any misalignment can prevent you from installing the retaining clip successfully!
  2. If you’re changing out the faucet cartridges, there’s often a plastic piece that will assist in lining up the cartridge for proper installation. If yours didn’t come with one of these helpful pieces, don’t worry! You can use a case puller or a simple wrench and nut to move the magazine from side to side until it snaps into place without any trouble.
  3. Moen has an extensive assortment of faucets and cartridges, ranging from single handles to double-handle designs. Before replacing the cartridge, however, make sure you accurately identify which type it is; a misidentification could result in an incompatible fit!

Reassemble the Faucet

Reassemble the Faucet
  • Step one is making sure all your parts are there. Get out all the items that were removed during disassembly and line them up in their respective order of removal; this will help immensely once everything is back together.
  • Once your parts have been laid out, look at them carefully; check for wear and tear and any damage that could have occurred before or during disassembly. This can range from rust and corrosion to creaking sounds when moving components. Taking a few minutes here will save time later, so be thorough!
  • After running through a visual inspection, ensure each part is functioning correctly. This way, when it comes to assembly, things will stay intact because of faulty pieces. Last but certainly not least, start assembling your faucet!
  • Each piece should fit like puzzle pieces, so all you need do is follow what was done while taking apart the original unit, followed by connecting relevant pipes and hoses, test each connection one by one with some pliers before securing them tightly with nuts/bolts if needed just as an added safeguard.

And voila! Congratulations, you now boast a perfectly reassembled faucet!
