Do you have any advice (including which tools I'll need) for changing the rubber washers in a drippy faucet?

The sink has one spout and a separate hot and cold water faucet. It's from the early 1990s. Any advice that you might have will be appreciated.Do you have any advice (including which tools I'll need) for changing the rubber washers in a drippy faucet?
LOOSEN AND REMOVE THE TOP NUTS SO THE STEMS CAN BE UNSCREWED AND REMOVED. USING A FLASHLIGHT-LOOK DOWN INTO THE FAUCET AND CHECK THE VALVE SEATS. IF THEY ARE NOT PERFECT, YOU WILL HAVE TO GET A SEAT WRENCH AND UNSCREW AND REPLACE THEM. TAKE LOOSE PARTS TO HARDWARE AND REPLACE THE BAD PARTS. STOP AT THE BOOK RACK AND LOOK AT ONE OF THE PLUMBING REPAIR BOOKS IF NEED BE. THE SITE I LIST BELOW SHOWS A PRETTY GOOD BREAKDOWN SKETCH, EXCEPT I SEE THEY ARE CALLING THE FAUCET SEAT A ';VALVE';. OTHER THAN THAT IT WILL HELP YOU FINE. YOU WILL NEED A WRENCH TO REMOVE THAT NUT UNDER EACH HANDLE. A SCREWDRIVER TO REMOVE THE HANDLE IF IT IS IN THE WAY WHEN YOU GO TO REMOVE THE NUT. YOU WILL NEED A SEAT WRENCH IF YOU HAVE TO REPLACE ONE OR BOTH SEATS. YOU SHOULDN'T HAVE TO WRENCH TOO HARD ON ANYTHING-DON'T DAMAGE IN THE COURSE OF REPAIRS.Do you have any advice (including which tools I'll need) for changing the rubber washers in a drippy faucet?
not everyone has a cheap faucet...you can replace the o rings all you want...chances are the valves need to be replaced...the cost for the valves o rings included should be under 20 dollars...good money not to do it twice!
Tools, channel- lock pliers, screw driver, crescent wrench. Once you have turned the water off, take the faucets off, take them to the local hardware store and see if they have replacement washer for it. Or if you want to just change out the old ones for some new you you can do that if you don't want to mess with changing the washer. Your call, the second will cost more money of course.
a wrench, a towel, a screwdriver and alot of patience. turn the water off under the sink first!!! take the cap off the handle using your screwdriver, take the handle off using the wrench with the towel between it and the handle to prevent marking the handle. the stem will be the next thing that you see. take the stem out using a wrench. then take the stem to your local plumbing/hardware store and get the correct washers for your faucet.
You should only need a phillips/flat screwdriver and a crescent wrench or a pair or pliers. The phillips/flat screwdriver is needed to remove the handle, and the crescent/pliers are needed to remove the stem. You can then remove and replace the washers with the screwdriver. Hope this has helped.
get the book' how to fix damn near anything'. great instructions and illustrations.
faucets are very cheap to buy...just get a new one and replace it....tools needed...a small pipe wrench...or a small pair of vice grips and some teflon tape
