It needs new washers every few weeks. Replacement units are under $100,

Ceramic cartridges? Something else?

I NEVER want to replace another washer, and appearance is irrelevant.
Is one of these what I want?

Those both sure look like they use washers to me.

But why do you have to replace yours so often. Mine last for 10 years
or more. I think one i use often is still original, 42 years.

I once bought a seat refinisher, but it seemed cheap and I wasn't
convinced it did anything.

Many faucets have replaceable seats. If the seats might be ruining your
washers and you can replace the seats, do that. They unscrew with a
flat-blade screwdriver. Somehow the slot doesn't interfere with the
seat or the hole, clever people these plumbers.


Good point about the seats maybe damaging the washers. There are tools
made to remove removable seats.

You're right. My bad. The tools have square ends. (I even have one of
them) There are no slots** in the seats, just square holes. Ooops, or
hexagonal holes, if they're newer. I don't think my tool does that but
regular tools would, allen wrenches.

**Nope, that's wrong too. Some have 4 notches that look like the ends
of slots, for the square tool.

If Bev looks in the hole and the seats have square holes or just 4
notches for the corners of the tool (or hexagonal holes!), I think that
proves they're removable. And if they are truly round, as opposed to
stripped almost round, they're not.

The seat in the picture has 4 notches and would be removed/installed
with a common tapered square seat wrench. Some newer seats will have a
hexagonal hole in the middle and can be removed with an Allen wrench.

Look closer at your seats for even the hint of the square notches. They
can corrode over and be less visible, but from what I see in your pics,
those are not removable.

For non-removable seats (and even removable ones), there is a
"reseating" tool for faucets that is basically a round grinding disk on
a T handle that can be used to grind down the seat a bit giving you a
new smooth surface. It is possible to grind too much, so you'd do a
little at a time.

Read the whole page above.

BTW, the 2 faucets mentioned above use cartridges, as shown in their
parts diagrams.

You might be right, but I don't see it.

This is the area and it says
RP42096 Stem Unit Assembly, Seat, Spring & Bonnet Nut

But you are right. Googling RP42096 gave.

I didn't know cartridges came that small.

Still, if replacing the seats stops washers from wearing out, it's a lot
less plumbing and wall repair to do since IIUC the plumbing here is in
the wall not under the sink.


BTW had same experience with a seat refinisher. Waste of time and money.
