How to repair a washerless bathroom sink drip?

Question

I have a drip in my bathroom sink. The faucet is washerless.

Answer 1

You have to ream the seat. You can get the tool for about $5.00 at most hardware stores, and they are very easy to use.

Answer 2

First off, if it's a washerless faucet it doesn't have a seat. And make no mistake, the difference between having a simple washer and being washerless, is that the washerless system uses SEALS instead of washers. They still need to be replaced occasionally, especially if you live in an area of high calcium or lime, or rust content in the water. You don't mention the make of the faucet ,but the majority of them, if it's not a Moen, have two small round seals, setting on two small round springs, in recessed slots on the side of a round cavity in which a ball rotates up and down and side to side, (if it's a single arm), or a plastic stem rotates around, if it's a two handle system. You should be able to buy replacement seal and ball or stem kits in your local hardware or home center. If you ask one of the attendants may be able to give you some help with how to disassemble the particular unit. If you do decide to tackle the project, use some petroleum jelly, (vaseline), on the springs and new seals when reinstalling them. They'll go in easier and last longer.
