MOEN Kitchn faucet, single handle with sprayer on deck (right side when facing), think it is model ca87524... when handle pushed right (cold) regular pressure, push handle left (hot) little to none and has been progressively getting worse. Started about 2 months ago, but escalated within last week.

THANK YOU for ANY help!!

It sounds like you have debris in the hot side of the faucet, close both angle valves under the sink and remove the cartridge 4000 open the attachment below and see the image, open the angle valve one at a time put a towel on top of the faucet to catch the water once it is flushed install the cartridge and see if it works, if not call Moen at 800-289-6636 explain your problem the will advice you what to do and if you will need new parts they will send it to free of charge, Good luck.

Thank you John!

Will check your suggestion(s)! I was not aware they would send new parts free of charge, the only problem is that I cannot go without the kitchen sink working for another day... We will check local hardware stores, saw that they suggested Home Depot & Lowe's carrying the cartridges, and hope they have them. I am very lucky to have someone to help me here (my husband, mechanic & great handy man, has sought 'greener EE' pastures)so that I do not have to call a plumber ;)

Again, thank you for the prompt reply! I have never been to this website before, and I thought I had seen them all! LOL!

Hello Maggie,

Yes Home Depot and Lowe's both carry the cartridge, good luck.

John

Thank you!

And so right you were. A piece of debris smaller than a chunk of clumping cat litter. ALL that mess for one little piece... sigh.

Thank you AGAIN!

Maggie

Hi Mggie,

Thanks for the update.
