Hi,

What a really great group and folks.

Sr. Citizen now, so bear with me a bit if I don't explain
my problem all that well.

Our bathroom sink has a leak.
The faucet has the very typical separate hot and cold
valves, and a center spout.

The center spout, right behind it, has the rod for opening and closing
the sink drain by pulling up and down on it.

When the water is running, a substantial drip develops on the
rod (under the counter), which I believe is called the "lift rod".

Not the horiz. piece where it enters the drain pipe, but coming right
down the vertical lift rod itself.

The ball fitting and gasket where the horiz piece enters the drain is
where I thought initially the problem was, but not so.

The drip is really coming right down the lift rod.

Hard for me to understand, therefore, where it is initially originating
from, and/or what causes.
How can water be getting from either faucet to this vertical rod ?

Any thoughts on this, or how to repair would be appreciated.

Hopefully don't want to replace the whole faucet assembly.

Much thanks,
Bob
