Expert News – Your Parts Could exist Free

If your faucet is less than v years old, information technology is still under warranty and Moen will transport you a new cartridge Costless of charge! I didn't fifty-fifty demand to produce a receipt. I contacted Moen by phone (800-289-6636) about the part needed and they informed me that in that location are two unlike models of the Moen Renzo, an older model, and a newer model. The way to tell which you take is to swing the on/off lever all the mode to the left and the right. If it swings a total 180 degrees then you have the older model and need cartridge 1225. If it only swings 110 degrees and so y'all have the newer model and demand cartridge 1255.

Bad News – The Manufacturer Instructions Do Not Assistance Much

The instructions they give you lot do not embrace everything! The instructions I received were very general and tried to cover everything from kitchen sinks to bathroom sinks to showers and didn't do it well. I likewise ran into some tricky issues that were not all covered by the instructions.

Good News – You lot've Found The Missing Instructions

Step i: Close off the water supply to the faucet.

It volition exist in the chiffonier beneath the sink and at that place will be 2 valves. Newer valves volition only crave a quarter plow in the clockwise direction to turn them off (and the handle volition bespeak perpendicular to the pipe) and older valves will crave you to turn the handle more, again in the clockwise direction. If you take the older blazon you may desire to plow the faucet on while you are shutting off the valve so you can make sure to end turning when the water stops flowing because those valves tin can be fragile.

Hot and common cold h2o supply valves (currently in the "ON" position)

Step two: Put in the sink stopper.

Information technology is probably a skilful idea to put in your sink stopper so that you don't accidentally drop ane of the pocket-size parts down the bleed of your sink. There's no betoken in creating more work for yourself!

Step 3: Remove the plastic plug from the faucet handle.

There should be a footling plastic hot/cold plug on the front end lower edge of your faucet handle. Ours used to accept blue paint on half of it indicating the common cold side merely the paint has long ago worn off. I used a knife to pry it out.

Step 4: Completely remove the set-screw from the faucet handle.

To access the fix-screw yous need to elevator upwards (plough on) the faucet handle. Information technology is a hex caput screw and you'll need an allen wrench to remove it. If yous need to purchase an allen wrench set up you can order one from amazon.com hither.

When I first did this repair I was not certain if I only needed to loosen the screw then the handle would slip off or if I needed to remove information technology completely only you lot do demand to remove it completely.

Here is what is going on inside:

Footstep five: Remove the phillips spiral from the top of the faucet handle hinge associates.

If you lot don't have a good set of screwdrivers then you can get a good Stanley ready here. Afterwards removing the spiral you will be able to remove the handle hinge.

Step six: Unscrew the top of the faucet associates.

This is the external chrome (or nickel or whatever stop you accept) meridian of the faucet after the handle is removed. I was able to do this by hand and I would not recommend putting a wrench on information technology or you volition really tear up the finish. Plow it counter-clockwise to remove it.

Step 7: Remove and prepare aside the metal washer.

Step 8: Remove cartridge clip.

Accept a knife or small spiral commuter to become it started. It should slide straight out.

Step 9: Loosen the cartridge for removal.

The replacement cartridge I ordered came with a special "twist tool" for doing this without damaging the cartridge:

Industry'southward "twist tool" for breaking costless the cartridge for removal

Identify the tool down on top of the cartridge and twist it back and forth (~45 degrees each way) with a pliers. If you don't take a good pliers you tin pick 1 upward hither. It did not take much effort to do this for me. I think that if y'all take hard water and a lot of calcium deposits and so this step may be more important for you.

Using the "twist tool" to loosen the cartridge for removal

Step 10: Remove the former cartridge.

Take a pliers and grip the brass post that sticks out the top of the cartridge and pull the cartridge straight up and out.

Pace 11: Clean the faucet barrel.

This step is recommended past the manufacturer and is probably more important if you take a lot of minerals in your water. Utilise an old toothbrush and scrub the within of the barrel to remove whatsoever mineral buildup. Once you take scrubbed the within of the barrel, plough the h2o valve on very slowly to affluent out any material you may accept broken loose when you lot were scrubbing the barrel. Be careful where the water runs when information technology comes out of the barrel–I idea mine would run back into the sink but it did run out on the countertop.

Step 12: Insert the new cartridge into the faucet.

Step xiii: Install the cartridge prune.

You may demand to turn the cartridge to line it up–use the twist tool every bit necessary. The clip should go on either side of the clear plastic lip that sticks upwardly on either side as shown below:

Reinstalling the cartridge clip

Step fourteen: Reinstall the metal washer.

Simply slide it downwardly on the contumely cartridge shaft. I forgot to practise this the beginning fourth dimension–learn from my mistakes. Also take your toothbrush and clean the top border of the faucet while yous have it open.

Stride 15: Set the hot/cold sides.

Depending on the way you orient the brass valve shaft you will determine whether the water puts out hot water when the handle is turned to the left/right. Based on the way our plumbing was piped, to make the faucet menses common cold when the handle is turned to the correct, orient the brass shaft so that the hole is on the front end as seen below:

The way I had to orient my valve to brand cold on the right and hot on the left

Step 16: Reinstall the faucet cap.

Screw it down tight. What happens when you screw down this part is that at 1 signal the white ring inside the cap "catches" and locks into place. In my instance, the white ring "caught" at the incorrect point and locked in backwards. The "channel" should be on the dorsum side once it is screwed down tight as seen below:

If you encounter the trouble I had with the white ring locking into place backwards you can take a spiral driver to hold the band in place every bit you spiral information technology downward like this:

Keeping the white ring from locking in the backwards

Step 17: Reinstall the faucet handle hinge.

This role was a bit tricky for me too. Y'all need to reinstall this swivel with the tab on the back into the groove I fussed about in stride xvi and the "cap" of the hinge down onto the cartridge shaft (without turning the shaft 180 degrees and switching the hot/onetime sides you lot set in step fifteen).

Hinge tab and the groove it must fit into

If the hinge is correctly installed it should swing dorsum and along as seen below:

Once the hinge is installed, reinstall the spiral on top:

Step 18: Reinstall the faucet handle.

Line up the hole and reinstall the hex-head screw with your allen wrench set up.

The handle should not be loose at all when you have reinstalled the screw properly.

Footstep 19: Reinstall the plastic plug.

This is the plug that covers the handle screw.

Stride 20: Test the faucet.

Turn both the hot and cold water supplies on and test out the faucet. If the hot and cold are reversed the follow these steps backwards to step 17 and rotate the brass valve shaft 180 degrees and then follow the steps forward in putting the faucet dorsum together. At present yous should be done!

Your handle should swing from left to right as shown below:
