Got a moen château faucet bathrrom facuet that has low pressure. All other water outlets in the house are fine it is just this facuet. Not sure if it is the cartridge. The hot and cold water is fine it is just the pressure that is a problem.

This "bathroom faucet", is it on the tub/shower or the bathroom sink? If it's on the lavatory have you removed the aerator from the spout and checked the screen? Let me know, Tom.

Sorry tub and shower unit. Moen 1 handle unit. You pull to turn on and left to right to adjust the water temp.

Shut the water off to the valve and open it up to the cartridge. Remove the brass horseshoe clip and pull the cartridge. Check the inlet pports on the cartridge for any trash. Now, whild the valve's still open turn the water back on to flush out the supplies. You should have a full stream when you do this. If not click on back and tell me. Reassemble and test.
Good luck, tom

Thanks speedball. I did what you asked but before I break anthing how does the cartridge come out? Does it just pull out once the clip is removed? If so mine is stuck. Any suggestions would be approciated. Thanks

Follow Tom's instruction, I will add the following link to show how to remove and install the cartridge, click on the link once it opens click on the Animation Enhanced when it is down loaded, click start and click next then click on the one handle shower which is #3 from the left and it will show you step by stem you may need Moen cartridge removal tool, good luck.

Thanks guys for the help but the problem seems to be getting worse. I removed the cartridge and flushed the hole where the cartridge goes into. Good pressure, all looked good there. I cleaned the original cartridge and attempted to put it back in the same way it came out. Opened the valve and had zero water pressure. Worst then before. Went to Home Depot and bought a new cartridge and installed per the directions. Same issue. I again removed the cartridge and turned on the water and had good pressure. Amy help would be appriciated.

I'm going to hafta ask. Did you remove the aeriator from the spout and try it then? Let me know, Tom

Tom gave you excellent advice you need to remove the Aerator from the spout see the image, try the water if the flow is good clean and install the Aerator, good luck.

Not sure about the aerator. This is a tub / shower unit.

Hello Dprzislicki,

Sorry for the wrong info I followed Tom and was showing how the Aerator looks like in case you were not familiar with it, my next step would be to remove the shower head try and see if you have water flow id you do clean or replace the shower head, good luck.

John

OK! You are pulling out the hamdle before you turn right or left? Hey! I'm grasping at straws here.
