the darn thing won't turn off. I have to keep it pointed in the sink to avoid getting sprayed. it has been sticking for months. recently I took it apart and soak it in vinegar thinking it was calcium buildup. it worked better for a day or two, but now it won't shut off at all.

I'd rather not buy a cheapo replacement as this is a moan brand and rather slick design that matches the rest of the faucet - fairly new.

the plunger (which controls shutoff is plastic with a thin "c" shaped wire/half ring about it. is this something that can be replaced. would I be better off calling moan for a matching replacement. i can't call them until monday. i guess I could use a cheapo replacement to crutch thru the wkend.

thanks in advance for your responses on how to fix.

 

HI uh-oh uh-oh, (i'm beginning to sound like Santa )

-as you probably know, all or most Moen parts are covered by warranty and generally free. (I say gen. as a few older parts are not) Most large plumbing or big box stores, HD for example, have Moen spare parts kits. Those parts are free to customers bringing in the old/broken part.
Try to dismantle and find the problem part and get it replaced.

Do it Right - Do it once.

 

really?! didn't know that. well thanks for the 411. I might be making a trip to the home center. much obliged.

 

It is probably the diverter valve in the faucet, but it may be the sprayer itself. Both can easily be replaced, which is what I would do (especially if you can get one free).
Good Luck!
Mike
