I have 2 Moen lavatory faucets that are hard to lift and open for water.
I have cleaned them and re-applied a plumbing grease on the insides
around the O rings but they are still very difficult to lift.
Do I need to replace the O rings, or is there a special Moen lubricant
Maybe you over tightened the ring ? Back it off some.
Its a common problem in plumming. You let any nut
drip some then tighten by hand until the leak stops.
Replace the O rings if you have a black substance left
on your fingers after handling. Vaseline is fine as a lubricant.
Many here would prefer KY jelly, but is dissolves in water.
Totally false. The petroleum in vaseline can damage the neoprene
O-ring in less than 24 hrs. You must use a non-petroleum lubricant, preferrably
a clear silicone paste.
John, it sounds like your having problems with the old style brass (#1200)
control. It was never intended to be taken apart by homeowners and lubricated.
Do yourself a favor and replace the old Moen control with the current composite
(#1225) control. If they get hard to operate they are easily lubricated.
Doug and others:
Tnx for your info. I did some more investigating and found that the two
small O rings inside the stem had swollen from age and thereby making it
hard to lift. After much searching I found that the proper size O
rings to use is a 7/16" OD X 1/4" ID X 3/32" thick ring, often referred
to as a size #78 by Danco. I found the O rings for $.25 each. This,
including a small dab of silicone grease did the job. Incidentally, the
same 3 items sell for about $3.50 at Home Depot, under the Moen item
#117, if one can find it.
Ok Doug, you are right on Vaseline, but I used it on my own
Valley made faucets. They still work fine !?
Hmmmmm that was a couple years ago. Could be Plummers
On over tightening.....I hire it seems ' relations' all are over 200 Lbs
and 6'4'' they are a bit strong. If they put in a electric outlet, the
home owner often complains they need a screwdriver with
channel locks to unscrew the screws.....
I HATE leaks from someone over tightening anything. Its a real time
I myself never had a leak in my whole life !
