My kitchen faucet is dripping. It is a single lever Delta faucet.
Sometimes it drips faster sometimes slower, if I push the lever down and
hard sometimes it will stop the drip - until I have to use it again.
Is this something that will require a replacement of the faucet, or
replacement of some parts? I plan to shut off the water supply, there is a
bolt at the base of the lever that I will open up and see. But not sure
what I am looking for. I tried to remove the entire faucet unit but the
"ring" at the base under the counter top is real tight and nothing I have
will free it, I have a wrench large enough but not at the angle where I can
apply any leverage and no room to have any "bite". Is there something I can
do to fix this from the top?
A single handle faucet will typically use a "cartridge" inside that is cheaply
and easily replaced. Normally you would be unscrewing a ring under the handle
(not under the sink) to get at the cartridge.
I doubt this one does. If it's like the single lever Delta I have in my
kitchen, it's easy to fix. There's a 1/8" allen screw at the base of the handle
in the front that you remove first (after turning off the water either under the
sink or the whole house valve and then bleeding off what's left in the line).
Wrap a rag around the chrome that's revealed when the handle is lifted off and
use a large set of channel lock pliers to uncrew the mechanism intact. Do not
mess with the white nylon adjustment nut at the top or any adjustment mechanism
for that matter; it isn't necessary.
What you're looking for is under the brass ball with the short shaft. Inside
the faucet itself you'll see two black rubber seats resting inside two detents.
The seats are sitting on a couple of little springs: note the position so you
can put it back together.
The leak is most likely caused by a nick in one or both of the rubber seats. Go
ahead and replace them both while you're there. Reassemble everything in
reverse order and turn on the water. You're good to go. There's no need for
further disassembly / reassembly. A parts kit from the borg should be under
If water leaks when you swing the faucet to one side or the other then you need
to go ahead and lift off the large chrome spicket and replace the two large
rubber orings underneath. If it's not leaking, then don't bother.

Those little rubber seats are easy to replace, but I should note that
the ball that connects to the handle often wears too, and will require
replacement. While you're at it you may as well replace the thing
under the cap where that ball rides against.
In other words, replace the rubber seats, and if it still drips, get a
complete kit. Or just get the whole kit right away so you dont have
to fix it twice. I am just dealing with a delta two handle tub
faucet. I replaced the rubber seats and it still drips on the cold
side. So now I have to replace the cartridge.
This is just my opinion, but when they came out with these so called
"washerless" faucets, the advertising made it sound like this was a
big improvement in faucets. What it really was, was a way for
manufacturers to make more money. The old washer faucets would
require new washers every 3 to 5 years (50 cents) for average use, and
new brass seats every 10 years or so ($5 for two of them). Now we got
cartridges and rebuild kits, and every brand is different, and they
all cost from $8 up to $30, and some are much harder to work on then
the old washer/seat faucets. I have also found that they last no
longer than washers, and in many cases last shorter.
Plumbers used to be able to carry a box of washers for which there
were about a dozen common sizes, and carry a few dozen of the most
common seats. Now they got to spend a fortune to keep all these
different cartridges in stock. This washerless thing is nothing but a
joke, designed to make more money for themselves.
By the way, Moen has the reputation for quality faucets. I do tend to
agree they are one of the better brands, but when it comes time to buy
a new cartridge, prepare to spend well over half the cost of a new
faucet for the cartridge.
I personally wish they would go back to washer faucets.
Or you can call Moen's toll free number and get a free rebuild kit, or maybe
even a free cartridge, assuming you are the original owner and you have a
lifetime warranty. http://www.moen.com/Consumer/products/warranty.cfm
woah there big fella. No need to boar hog the entire faucet. The
only thing you need is new O rings. Less than a buck at your local
Most single handle faucets have a cap of some sort covering the
handle. They are usually held on by a small screw or just snap on.
Carefully determine how it's held in place and remove the cap.
1. Turn off the hot and cold water from underneath the sink.
2. Cover your drain hole so you don't have anything fall into the
3. Unscrew the bolt holding the faucet handle in place.
4. Remove the assembly containing the rubber O rings and take to your
local hardware store, or even simpler, just remove the O ring and take
it to your local hardware store and buy a replacement. They come in
kits with varying sizes or can be purchased individually for about 10
5. Bring home, install O ring an review installation procedure.
It probably needs more than the o-rings...typically the ball cartridge
wears and no longer seals as well.
It seems as though Delta parts have gotten much more short-lived than
But, this reminds me...I need a kit for the one here as well...maybe I
can now remember when I go to town for the mail after lunch... :)
forgot about the cartridge. Still shouldn't cost much though and is
pretty enough to replace.
You're so right on the Deltas leaking much sooner than before. I
suspect they've outsourced some or all of their parts.
I've had good luck with Delta in my old house. When Imoved here, I had to
replace the rubber parts and cartridges every six month. I cursed Delta and
swore I'd never buy another. After a couple of years I put in a whole house
water filter with a sediment cartridge. I've not had to repair a faucet
since (10 years now). I do replace the filter cartridge every few weeks and
it has a lot of rust in it that was abrading my faucets.
One thing I've noticed is that it seems that Delta for the most part has
gone to plastic whereas you can still (if you look hard) <sometimes>
find metal replacements...these seem to last longer still...
Hard water such as we have is definitely a contributor, too...
And, if there's a hose sprayer involved, spend a couple of bucks more
and replace the "diverter valve" while you've the faucet open, they
usually "go" about the same time as the seals. (Lift the faucet spout
straight up and off after you've got the top cap off to get at the
Oh, and those top caps on the Delta faucets can sometimes be bears to
unscrew. Slip joint pliers work, If you don't care about marring the
nice knurling on them. I've never had any luck wrapping them with
adhesive tape first either, the plier's teeth cut right through the
tape. Much better to use one of those "boa" strap wrenches for that part
of the job. If you don't have one already, they really are the cat's ass
for jobs like that.
Disregard the other replies.
Go to Delta website:
They have excellent repair procedures.
Take handle off.
Loosen big chrome nut under the handle (may be corroded on).
Inside you will find the Delta "ball".
Under the ball are 2 sets of "springs and washers".
Replace ball and spring/washer with Genuine Delta parts; forget
about generic parts.
Get the seal kit too which has the parts on top of the ball.
There is another kit with the O-rings for the spout.
Although you can get Delta parts individually, your first repair is best
done with a rebuild kit, which most home centers sell. Less than ten bucks,
comes with a couple of special little tools you'll need. Put a large towel
over the drain. There's a hex screw you have to remove from the faucet
handle. Gremlins will make it want to go down the drain. Did I mention you
should put a towel over the drain?
Don't forget to put a towel over the drain, by the way.
I second this. GO to any big box hardware store and buy a Delta rebuild kit.
It includes everything needed including the wrench to remove the innards and
instructions. My experience is that you have to replace everything to stop
the leak. Replacing just the ball or just the seals won't do it. You can buy
rebuild kits with plastic balls or metal balls. The metal ones work better.
Plastic balls are cheaper. I've done 4 faucets so far. Piece of cake.
