I have a leaking Delta faucet. I bought the repair kit. Replaced 2 0-rings,
washers & springs. Ball seal and cam. Put the whole thing back together
and it leaks whenever the water is on. I've got the thing tightened down pretty
Also, and this may be the problem. I keep seeing references to a pin
that should line up with the slot on the ball.
There is no pin on my faucet, only a tiny hole, where maybe a pin was...
Any ideas on how to stop the leaking?
Jim - thanks, but I replaced the cam and seal as well.
The odd thing is that when this all started, for months this thing had
a slight drip when the water was running. In one day it went from a slight drip
to a heavy leak, which is what prompted me to do the repair. Now
I'm thinking that something internal has failed.
This unit uses a separate spout for the water, and I did see a small
plastic disc (the diverter, I think it's called,) anyway, I wonder if
that is the problem. I didn't see the disc in any of the replacement kits
at the store.
Where is your faucet leaking from? The end of the spigot? Down along where the
faucet pivots from side to side? Out the top where the handle is?
If it's #1, it's one or both of the valve seats. Remove and inspect/replace
them. There should be no nicks or noticeable defects.
If it's #2, it's the one or both of the two big o-rings. This time when you
replace them, consider applying a thin layer of food grade silicon grease to
them before you install them... just enough to make them look wet.
If it's #3, it's the rubber packing just on top of the ball assembly... or it
just needs to be tightened down.
You may have loose scale, sand, small rocks, in the pipes that is working
it's way into the faucet when the water runs.
pull it apart again and see if something is stuck under the new seals or
You may have to flush out the pipes.
Some have a pin others have a slot, you might have to replace the ball too
if it has ANY marks.
If the seals and ball are good you don't have to crank it down, just a bit
over finger tight
But many years ago I knew a plumber who just looked at any delta faucet, and
would only rip them out and replace them with "Moens".
Always said he had too many problems after trying to repair them, as the
housings used to corrode, and they would leak again less than a year later.
Side note: moen supplies new cartridges for free if they EVER start leaking.
