No charge.

It sounds like the fine threads on the collar are stripped. Either replace the collar, or try some locktite.

Sounds like your spray head on the faucet needs replacing. They do plug up with rust and corrosion every so often. You can take it off and try to clean it but be very careful it may still spray when you put it back together.

Parts for that model can be found at amazon, take a look: Were doing more than just throwing away the key. Have a nice day

This is the exploded view. The cartridge is available at any hardware store. http://www.moen.com/shared/docs/instruction-sheets/ins111a.pdf

With this type of faucet when you push the 2 pieces together there should be a small rubber O ring, if this is not in the correct position there won't be a proper seal. If you have some vasalien rub it on the O ring and it should help it fit better, it also should click when you push it together.

Here's a link to show you how to get the spout off using "strap wrenches" The allow you to get the nut off at the base of the faucet spout without harming the chrome finish.http://blog.trebacz.com/2012/12/how-to-fix-leaking-moen-kitchen-faucet.htmlThere is also a video at the bottom of the blog post showing how I did it.

there might be a allan screw holding it down usually located at the back of the faucet if not there is a chance that there is a screw on escutcheon just above the base of the spout this should screw off with a strap wrench.

You can just replace the o-rings. You have to remove the large nut at the base of the spout. I posted a blog post -and a video about me replacing mine.http://blog.trebacz.com/2012/12/how-to-fix-leaking-moen-kitchen-faucet.htmlThe replacement o-ring and retainer parts were free to me. Hope it helps you.

Moens balancing spool moves back and forth inside the cylinder to regulate flow of water to keep you from getting scalded. If it is not working properly you can get to much of hot or cold water coming out of the spout....or low to no water coming out.

Grab the base of the spout and turn it counter-clockwise.It should come right off.

tighten the lock down nut under the sink , also,, unscrew the cap (at the base of the spout,, and Lube the O ring ( with either plummer grease if you have it, or if not with vasoline) this should cure your problem

It needs to be taken off and lubed. If you don't have plumber lube you can use vegy oil but it will not last like plumbers lube.

Cartridge removal is a simple matter of exposing and pulling out the old cartridge. Before getting started, turn off both water valves underneath the sink and allow the water to run until the line is clear. Using a screwdriver, gently pry off the cap on the lever of the faucet handle to expose the cartridge. Remove the U-shaped retaining clip that holds the cartridge in place and pull the cartridge out. If dirt or residue makes removal difficult, use a Moen cartridge puller to assist you. A cartridge puller fits over the cartridge and gives you greater pulling power.

Soak the dirty cartridge in vinegar for four hours and replace.

If cleaning the cartridge does not work, call the Moen Helpline at 1-800-465-6636 or Customer Service at 1-800-465-6130 to order a free replacement. Locate the part number on the cover page of your instruction manual. If you no longer have the manual, look on the underside of the spout.

They generally are very good about taking care of their productc however be prepared for a extended wait to get through.

If you are talking about the areator you can remove it by turning it to your right . You can remove the screens and brass disc and clean them with soft brush and cleaner like mild C.L.R. and water solution. This will clean lime and mineral scale from them. Do not use this on outside finish. Use softscrub and soft cloth to clean. If the finish is too badly discolored you can get replacements at most hardware stores or for special finishes go to moen.com for location of dealer nearest to you. To install just reverse steps. I hope this helps you. Thanks

the pipes are banging in the wall from water hammering and need to be straped. or a hammer aressetor needs to be installed.

I would use what is called a strap wrench it would be best. That way you do not mess up the finish on your faucet or leave marks on it from a pair of channel lock pliers.
