Moen One-Handle Kitchen Faucet Leak - Hot Only

Question edited for correct spelling of maker 'Noen' to 'Moen'.

'Fix' as in it is leaking? Or tighten it down because it is wobbly, or something completely different?

The nuts used for capping off the sprayer attachment will bottom out and not seal. Unless there is tape or thread compound on the nut, it can spray a tiny jet up under the faucet when the faucet is activated. If there is clearly water leaking from above that, then the o ring for the spigot may be failing and need replacing. If this is the case, it will only leak when the faucet is activated. There is always the possibility of a crack in the casting of the faucet body; hope not:)

I did the same thing recently, that is replaced the cartridge on my moen kitchen faucet to stop and leak, and I also have the same problem. I called moen back and they sent me another cartridge that was supposed to fit tighter, I suppose. I just put the new one in and it still wont stay up. I'm going to call moen one more time and then I guess I'll have to buy another faucet, but NOT moen!!! Good luck with yours.

This might mean that the diverter in that controls the sprayer needs replacing. It is located behind the valve body underneath the tub spout sleeving

Hot water line connected to left side of faucet? Did you replace tap set, or just cartridge? Cartridge may be out 180 degrees.

turn off water remove handle and check retaining nut remove cartridge and check o-rings for damage or replace replace and tighten cartridge check for leak

cartridge does not stop that type of leak. If it is leaking from around the base of the spout it is o-rings that are the problem that are onthe valve after you pull the spout all the way off.

You have a bad internal o-ring or the sprayer o-ring is leaking, if you look under the sink turn it off and then turn it back on, if you see it leaking out the center shft where the water pipes go into then the faucet may have a broken pipe or loose pipe. check and tell me where it's leaking at. You can buy kits to repiar them they are inexpensive.

wow... I wish you hadn't gone thru the expense of replacing the faucet... it's perfectly good... your problem was the aerator, it unscrews at the tip of the water spout and had collected too much sediment which eventually blocked water flow. Often happens quickly after your water is shut off at the main valve. Aerators cost about 50 cents...

Single or dual lever? A new ball if single lever. Home Depot or Menards will carry them. Teflon tape if dual cartridge. Stay away from moving parts
