Hi all

I am messing with TWO Moen "Chateau" single handle faucets with side sprayers,
with what I believe are similar problems. One I bought new at my house, and
was handed it in a box when I went to clean out because "the diverter was bad
and I had a handyman replace it" (as I was told. I was not present to observe
exactly what prompted the replacement.) The other is installed in my friend's
house.

The one that is still installed has had problems with the side sprayer. Based
on the deposits that I see on it, they have hard water. The issue is that the
sprayer does not stop spraying when you release the trigger. I took the
sprayer from the old faucet from my house and installed it on his hose and
that one works better, but it still dribbles water when the trigger is
released, it does not completely shut off. This leads me to believe that the
diverter valve is not functioning on THIS faucet as well. Currently they've
been using it with the sprayer just left hanging in one bowl of the sink, but
that to me is an inelegant solution and I'd like to fix it.

Does this sound reasonable? Both faucets failed quite "young," mine maybe two
years after installation, my friend's less than a year.

I do have both of the side sprayers currently soaking in glasses full of
vinegar right now in an attempt to free them up...

I would suspect the hose end nozzle valves. The diverter valve, as far as I can
tell, just shuts off the water to the spout when the hose valve opens
sufficiently, thereby increasing the pressure at the hose..
