Bathroom faucet cartridge replacement 

Thank you very much for making this video. I'm an 80-year-old woman who's decided that life is too short to depend on others to take fix things, and this was my very first foray into the world of plumbing. Your calm voice and careful photography saved the day. Thank you SO MUCH!

Excellent tutorial! I’m glad you showed it was incorrect and how to correct it. Thank you for no music. I could hear you clearly!

This is just what I was looking for! A tutorial that went slow enough for me to remember and understand what to do! I could do this myself! Thank you

I received some very useful advice when changing the cartridge: First, before inserting the new cartridge, rub silicone grease along the cartridge and inside where it fits. Also, before putting new cartridge in, turn water back on very briefly to flush the faucet. Thanks for the video.

I just replaced the cartridge (1225b) in my bathroom Moen sink faucet. This video made the effort quick and easy! I too encountered the same problem with the hot and cold water after the initial installation. But, thanks to the video, I was able to resolve this issue in no time at all. I doubt this effort would have gone as smooth if I had to rely on the paper instructions that came with the cartridge - which I found lacking specificity. In summary, a great, informative video that saved me $$$ by not having to request assistance from a plumber!

I just watched a video on how to change a single handle Moen cartridge. Please note you don't spin the complete cartridge to change the hot water to the left side, you only spin the center that the handle screws to 180 degrees, thus you can do this without taking the copper U clip back out. Put the screw in it so you can pull center stem to on grab with fingers and spin 180 degrees which amounts to half a turn. Done!

Thanks for your video. It' was clear, close-up and actually shows what to do! I was able to change the 1225 cartridge successfully. I had some difficulty removing 16 year old cartridge, but sprayed 100% vinegar on it and in 5 minutes it slid out!

Thank you for getting down to business without 5 minutes of "broadcast performance for the viewer's entertainment" as an introduction to the task at hand.

You just saved me from having to ask the guy at the hardware store. Now I can walk in like I know what I'm talking lol

Great video. I changed my cartridge. Used a cartridge puller as it was a bit hard to get out. Part of the rubber sleeve broke off and jammed it so the puller helped. Then I had to get the rubber unstuck from the cold water hole. After about ten minutes of trying to tweezer it out just ended up turning on the cold water in short bursts to flush it out. Of course then after putting cartridge back in it was backwards (hot water was on right) so I had to switch it 180. Put a touch of silicone grease on it and now runs perfect. Your video helped me through it all. Thanks!!!

got my new Moen Cartridge yesterday (10.27.14)... had looked at this video several times... it went smooth as silk... I used that plastic cap and got my old one out with no problem at all.. thank's for this video and thanks to Moen....no drips or leaks now...

180 off, thats when I start speaking french

Thanks Mike couldn't have done it without watching your video.

Great video. Really clear both in terms of video quality (closeups) and step by step instructions. Thanks!

Thank you so much for this video. Very helpful. We fixed our leaky bathroom faucet!

Thanks for this post! Great resource.The tip about the 180 rotation was excellent. Bless you!

Thank you so much! This really was helpful. I'm used to fixing the old style cartridges where you just replace the washers. This had me flummoxed! Just wish I had watched the whole video before doing it as I was struggling to get the old cartridge out with a pair of plyers. I could have used that plastic thing, would have been so much easier!

I can't thank you enough for this video - it worked perfectly for me! The only issue I had was a stuck handle screw, but a little WD40 and a quick tap with a hammer fixed that issue. THANK YOU, THANK YOU!!!!!

Thanks for posting. I did this job last weekend and your video helped a lot!

Great step-by-step video, thanks. I like that you "accidently" put the cartridge on backwards, so that you could demonstrate how to (easily) correct the problem.

Followed your video instructions and replaced my moen cartridge today. Worked like a charm...thanks!

This is one of the best You Tube videos on this subject I have seen. Thanks iScaper. As others have said, if you have hard water guaranteed pieces of the rubber on the cartridge will break off and you'll need to spend a LOT of time getting them out. I fashioned a tool out of a coat hanger (small hook at one end and a short 45 degree bend at the other) to help me pry the pieces out of the left and right side holes and drag them up the walls and out. Sort of like one of those arcade games! Also, be sure to get the cartridge puller tool because if you do have hard water, getting an old cartridges out will be impossible without it.

Going to give it a try. Thanks for the DIY info.

Thanks, you saved me $100.00 for the plumber call. Maybe more when the other five valves go. They are 23 years old. Very easy.

Worked perfectly. Saved time and money. Thanks!

buy the Moen cartridge extractor/ stem cartridge wrench FIRST! Do not try to extract the old cartridge with pliers. If it's very old and/or your water is hard, it will break. Then it'll really take a lot of time. I have replaced 2 that were installed in 1986. First one without the extractor, the second one with the cartridge wrench. The best $12 you will ever spend. Without stem wrench the job takes 7 hours due to disassembly and removal of broken cartridge. With the tool it takes about 45 minutes. Good video, BTW.

Thanks for video, helped me fix my faucet.

Very helpful. I would love you to be my teacher. Brilliant. Ty

Great video!!! It really helped me, I had the exact same faucet and you walked me right through it on how the change the cartridge, even getting the part! Lowe's couldn't even help me there! I made 3 trips and was given the wrong part every time!!! Looked at your video a little closer and got the part # and it worked. So happy now

This video was well thought out and very well done . It is very helpful. Thanks for taking the time to make the video.

Thank you so much... you made it look very easy !!!

Thanks! Just did the job myself, though I had to pull with a lot of force to get the cartridge out. Also, it will be easier for people to find this video if you title "Moen 4621 or 46XX Chateau Faucet 1225 Cartridge Replacement" I ended up going through 5-10 videos before I finally found yours. Definitely a big help! My thanks!

Great video! Concise, complete and to the point. So many of the plumbing videos are so talky, that I practically fall asleep halfway through. A lot of gab about nothing. Plus, you obviously had your camera on a tripod. I was watching one the other day where the presenter used a GoPro mounted to his hat. I got motion sickness watching it and had to turn it off. Yours is very, very nicely done. Thanks for the excellent tutorial!

This was PERFECT. Thank you so much for to-the-point and detailed instructions. I followed your steps and it worked like a charm. Also, so glad that you showed how to rectify the incorrect hot/cold installation.

Great video! Very easy to follow. THANK YOU!! I got it done, all it took was a little bit of elbow grease to tease the old cartridge out. I'm a "senior" gal over 70. Just call me Josephine the plumber, lol.

Thanks. You provide a very thorough progression on how to change the cartridge.

Thanks for posting this video. You saved me a lot of money and time. I really appreciate it, I’ve subscribed.

After watching a few different videos on this type of replacement, yours was the best I had found. Thank you for your assistance.

That's not a spacer that slides over the cartridge. It's a small circular washer.

Can someone tell me if Moen cartridges 1225 and 1225b are interchangeable? All the info I see online basically says they are, except that there are 2 types they won't work on, obviously. HELP!!

Here's a quick tip for determining if the cartridge is 180 deg off. Just turn one side on. Hot or cold then check for orientation. One way will have water, one wont. If it corresponds to the side you turned on, you're good, otherwise rotate the cartridge. That way you don't have to wait for the hot water to get to the faucet.

thanks just saved me 120.00 for not calling a plumber which I did for the kitchen faucet easy to follow instructions by the way I am almost 77

be careful! my old faucet had a tiny leak from the hot water side, but the shutoff valve for cold water would NOT shut off. I had to shut off all water to the house and a plumber put in a new 'ball valve' for hot and cold shutoff. and now I can replace the Moen cartridge. Turning off all water in the house is easy.... but if you try to replace valves and anything goes wrong.... good luck getting a plumber! So I hired one just to install 2 new shutoff valves in about 10 minutes and I have 2 more in the adjacent 1/2 bath faucet I can do at my leisure. ... Replacing the Moen faucet cartridge using the small plastic too supplied made replacement a breeze in a couple of minutes ... Rotate the cartridge left and right 5-7 times and then gently pull it all out...

Hi, iScaper1, thanks so much for this nice clear how-to tutorial! If you're still monitoring this video, I have a question for you. My Moen single handle bathroom sink faucet suddenly stopped shutting off all the way - when the handle was in the down (shut off) position, the water would not shut down completely, some continued to flow through the faucet. It's not just a drip, it's a stream of less water than when the handle is in the on position, but still a noticeable stream. So I turned both hot and cold water off at the cut off valves and went looking for answers. When I asked a plumber working in a neighboring condo, he said it sounded like I needed to replace the cartridge, so off I went to you tube and found a number of videos, yours included, on how to do that. Seemed like something I could manage, so I went to the neighborhood hardware store, asked one of the old-timers there, and turned out he agreed with switching out the cartridge, so I got a Moen replacement cartridge for the type of faucet it was, switched out the old for the new...and it did not solve the problem. But what I did find out was that when the change-out was done and the water switched back on, it WOULD shut down completely if I was running the cold water, but if I was running the hot water, it would not. So...any suggestions on why that might be? I'm pretty much resigned to replacing the whole faucet, but I'm still curious as to what mechanism on the hot-water side of the assemblage would cause a problem like this! Thanks for any help you might be able to provide!

What is the purpose of the small spacer right beneath the knob? How necessary is it? Any idea what would happen if I omitted it? Somebody who took the faucet apart in the past must have forgotten to replace it, so I don't have one...

Thanks, worked great...my wife thinks I'm a stud

If hot and cold directions are reversed, I think you can just rotate the center moving part of the cartridge 180°. I don't think you have to rotate the entire cartridge.

Replaced cartridge moen in bathroom sink tap, put back together, turned water back on, but water will not shut off using the tap.

What if the plastic remover tool piece breaks? Cartridge is STUCK

Great job on video, even shows how to reverse hot/cold by rotating the cartridge 180 degrees.

That was great! I fixed my leaky sink!! Thank you

exactly what I was looking for Roy Wells Trenton , ont, Canada

Thanks so much for spending the time to produce and post this very helpful video! Can you please tell me whether if the replacement cartridge used in the video was Moen 1225 One-Handle Bathroom Faucet Cartridge?

I have to do this to my faucet. Glad to know plastic nut comes with replacement cartridge...thanks

This is the best DIY video I have seen. I am the worst DIY guy on the planet. Yet, with this video, I was able to replace the faucet cartridge like a pro. Thank you for this great video.

For the 3rd time, it's a washer! Stop calling it a spacer!

Anyone know part #

If you install it backwards all you have to do is rotate just the brass stem not the whole thing.

No reason at all to put the cartridge in wrong if you know what you’re doing!

great products Moen,,last decades and easy to fix and still carry the parts.

I followed the steps and replaced my Moen small single handle faucet cartridge. Thanks for the video!

Thank you so much this helped exactly what i needed

Awesome tutorial! Followed step by step and worked to a T! Ready to open plumbing shop! (on second thought) Thanks! 😎

Great video very well explained. Love to be able to fix it and no more leaking wasted water 👍🏻😀 thanks Now unto an old none working big time leaking garbage disposal. Yipes 😱

Excellent Video, thanks! I like that you did this replacement job w/o use of the special "cartridge extaction tool" (used by many Pro Plumbers) that most homeowners don't own.

What if you cannot pull the old cartridge loose??

Hi I've done some of the cartridge removal myself. But lately I'm stuck with slow drip even after putting a brand new cartridge. What am I missing ? Maybe the distance of the cartridge (how far down should I push the cartridge when installing it ? just enough or a little bit deeper ?) Could it be something else I'm missing ? Thanks.

What a fantastic video!!!! You did an excellent job showing how to do this procedure step by step so that an inexperienced girl of 65 could do this herself! I also put in the cartridge the wrong way. But thanks to your video I knew how to fix it so hot ran hot and cold ran cold! Thank You Thank You Thank You!!!!!!!!

excellent video. Exactly what I need...just order the replacement cartridges and will try it out...many thanks..

I have a Moen faucet in my bathroom just like that. It's constantly dripping. Which cartridge should I get? My husband and I are on a fixed income and don't want to have to pay a plumber to fix it. Thanks for your help.

Most plumbers will tell you you need a new faucet.

Thank you so much for this video. It is very clear, and actually shows the procedure, and the hot/cold backwards issue. I know nothing about plumbing, and I was able to change my cartridge successfully. I now have a working, not leaking faucet!

Thank you! You were very clear in your instruction and I now have an understanding about cartridges in faucets and what the plumbing supply store is talking about when they talk about needing a new cartridge.

Just did this, Thanks...... Skilled laborers, with RU-vid, are a god-send.

I gather there is no way to tell if you have the cartridge in the right way for hot/cold on the first try?

arghhh... Looks simple enough but I can't get the knob cover off to get at the screw. Oh well, Ill try again tomorrow.

This video, of the several available, is the best by far. EXCELLENT!! Thank you.

Great video and to the point. what was the part number on the cartridge? thanks

Thanks for helping this dummy.

Great video, was that a 1225 cartridge?

Thanks for posting this video. I almost gave up trying to replace the part months ago. I gave up and was just going to replace the faucet but after months of looking at the faucet, I tried one more time because I had bought 2 replacement parts. The rubber gasket at the bottom is very fragile and if it goes in too fast or the wrong way it will tear and you have to buy another one. Needless to say, I fixed it and my wife is happy. 😊

What if the old cartridge is so stuck that it won't come out?

Saved me time and $$. Thanks so much!

Very helpful thanks

Thanks for the great video. Saved me a lot of money for not having to get a plumber, and made me out to be a hero with my wife!

Well explained and easy to understand video. Had no idea what a cartridge was, but with your tutelage was able to replace - and rotate 180° to sort out hot and cold water. Thank you sir!

Great video, thank you!

Thanks for posting. Very clear instructions.

iScraper, this didn't work out so well for me. I think your instructions were spot on but I have an issue with the replacement part. I put it in and got everything back together. When I turned one of the water lines back on, water started to flow despite the handle being pushed all the way in. I took the handle off and believe the cartridge was all the way in, I was able to get the clip to go on fine. One thing I didn't have when I took the old one off was the spacer. Could that have been the issue? Another problem I have now is I tried to take this new one back off and the rubber base at the bottom came apart. I can see part of the bottom rubber down in the water hole, YIKES! Am I going to need to take whole faucet off and somehow clean it out? Should I just get a new faucet to put in there?

Hi awesome video, so is this 1225 cartridge?

Excellent! I have to do this tomorrow!

One mistake. Pull the stem all the way to the top of the cartridge BEFORE inserting into the faucet. If not one damages the bottom seal. I did it twice.

Your welcome, much easier and no danger of tearing a o-ring on the old brass. Good day!

Good video .

No grease or silicone in the bore??

Sir do you know if this is a single hole faucet? I cannot find the answer. I want to replace mine, the hard water got the best of it!

thank you very much for this.

Very helpful video. Thanks

Hi iScaper1, great video! Initial symptoms, there was water trickling just under the handle when on (hot and cold), streaming towards the right back side of the faucet. The old cartridge was removed effortless. The new cartridge was inserted in smoothly, however, the water would not go off. After removing the new cartridge, you can feel two rubbers protruding out on both sides inside the facet where the cartridge goes in. What do you think?

Thank you so much, ..I'm a new DIY'er and appreciate the instruction and mind for small details...I had to go back and make sure the clip was fitted in all the way and put in the small washer underneath the new handle I purchased that was unfinished until I viewed your channel ..You have me feeling accomplished!!!
