The aerator is screwed into the faucet assembly. Sometimes lime deposits make this hard to unscrew so you may need large pliers with a lot of tape to protect the finish from scratches.
- remember, left-loosy/righty tighty, but it's upside down, so clockwise to loosen, when viewed from above the faucet.

Look at the back of the drain pipe directly below the sink. There is something that resembles an oversize nut that can be turned; turn it like a nut to loosen it. As soon at it is completely separated from the threads, hold on to the nut and the rod that goes right through the nut. Using one hand to hold onto the nut and rod at the same time, push the rod into the drain and rotate it downward a little. Drop the new drain plug into drain with the tab (with a hole in it on the bottom) facing away from you with the other hand. Now comes the slightly tricky part. Use hand to hold onto the nut and rod and use the other hand to hold onto the new drain plug in the correct orientation. Back off the rod away from the drain a little bit and drop the drain plug a little to align the hole (on the tab) with the rod. Now move the rod back into the drain and ensure that you've inserted the rod onto the new drain plug by rotating the rod up and down. Once everything's in place, tighten the nut back. The nut should be tight, but not too tight or the drain with be hard to open/close. Hand tighten it only, don't use a wrench. A common mistake is to not have the nut aligned properly when you start tightening it, just be sensible about it. An experienced person can do the whole job in under 2 minutes.

Hi trw151,

Here is a webpage with a blowup of the way the parts go together. Don't think it needs explanation: http://www.moen.com/shared/pdf/4621pt.pdf

Take note of the retaining clip and where it fits.

Tip: Put a tiny bit of vegetable oil or vaseline on the new O-ring when you install it. That makes for a good seal.

Hope this helps. If it does, I'd appreciate a 4 thumbs up. Thanks,

Handie Andie

ooops, didn't mean for that to be a request, sorry...It was a solution. Although, if you dont want to deal with Moen, you can get one at your local plumbing suplly store. I recommend taking the old one with you (make sure you shut the water off first!). Again, good luck

First clean out your cabinets under the sink. Second turn turn the cold water valve off, hot water valve as well.
You should be able to locate the sprayer hose as it will have a weight on it, this helps to pull the sprayer back when you are finished with it. Remove the weight by lifting up on the tab should be on the center of the weight.
Then you should see the hose connection.There you should see a button.Push it in and give it a little tug. The hose should be disconnected. Just follow in reverse order to reinstall.
I hope this is information is helpful. Have a blessed day.

Turn supply valves off, turn on tub valves to release pressure, then remove the handle on faulty valve. Check to see if it has a plastic cartridge. If so, it sounds like the rib was broken on the valve and it is out of alignment with ports in valve body. Take the cartridge out and take to your favorite home supply for a replacement. The cartridges have a key rib that fits into a slot so turning the handle turns the stem and not the whole cartridge. You might also find a black washer and spring under cartridge, it's a good idea to replace washer whenever cartridge is replaced also found at home supply

The hose or the counter weight is probably hooked on something under the sink.

I know this probably sounds silly, but are you sure you installed the batteries correctly? Try another set of batteries.
