How do you repair a leaking bathroom Delta sink faucet?

Answer 1

I would suggest going to Home Depot or Lowe's (Or another similar store) and ask them this question. It would be a good idea to have the particular model of your faucet, as they have changed over the years. They should have replacement parts.

Answer 2

Get an OEM Delta repair kit and also replace the springs under seat washers. This is for a single-handled delta faucet.

1. First, turn off water supply.
2. Next, get hex wrench and loosen hex set screw underside of handle and pull off.
3. You will see a cap with six-sided boss on it. Get adjustable wrench and unscrew.
4. Under this is a plastic cap with tab on one side that will slide in slot on the body. Pull off.
5. Under this is the ball with about 3/4 inch long by 1/8 inch lever on it. Lift out.
6. There will be two black 0-rings at bottom. Get needle-nosed pliers and pull them out.
7. Each will be a small black cap with a spring in it. Take 0-rings with ball to hardware store. If there is no helpful person there, go to faucet repair aisle and look for single-handled delta faucet kit. They will cost about $2-3. Compare what is in the package to what you removed. If there is a handy-man there, let him evaluate the condition of the surface of the ball. Mine was pretty worn, but he said it was OK. A new ball costs $6-8 so you be the judge. Buy small tube of plumber's grease.
8. When you get home, put the small end of the spring in the cup O-ring. Put into the hole. This is kind of delicate work, be kind to the O-ring and it may last longer.
9. Press firmly into place with your thumb. I had to use original springs on first faucet because I could not get both of them in. The springs that I purchased were a little too long.
10. When the O-rings are seated, apply thin-film of grease to ball. You will see a moon-shaped slot on the ball. Orient the ball so this slot fits into the tab on body.
11. Put plastic cap back on with the tab aligned with the slot in the body. Press very firmly as this assemble must be aligned when you put the threaded cap back on. I would grease the threads on the cap.
12. Tighten snugly with wrench.
13. Now, comes the hardest part. Unscrew hex set-screw in the handle completely so you can see thru hole.
14. Put in stopper or place towel in basin so when you drop something it wont go down drain.
15. Put handle back on sliding it onto the ball lever. I had to get flashlight to see that I had gotten the handle on the lever.
16. Place set-screw on end of hex wrench and put back into hole and tighten firmly. If handle rotates properly, good.
17. Turn water supply back on and lift up lever and look for leaks. If there are any take handle off and trouble-shoot. If not, good-job.

Answer 3

This can actually be a very simple task, or complicated depending upon the route you choose based on time and cost efficiency. The most common and simple place to start is replacing the "o" rings. An O shaped washer that is in the faucet. There are lots of how to or DIY videos on the internet and it is very simple. This is quick and very little cost involved. Your second option is to replace your existing hardware. This might be an option if you have a faucet set-up that is old or more dated than you like, and this can be as inexpensive or as costly as your taste in fixtures allows.

Answer 4

Get a Delta shower parts replacement kit from Hardware or Plumbing store and rebuild the faucet. Must get the right kit for the exact faucet.

Answer 5

Often the leak is from the faucet or pipes leading from the sink. Find out where specifically it's dripping from and repair or replace that part.

Answer 6

Either tun off the supply at the main stopcock (which will stop the drip) and or replace the tap washer while the main supply is off (then turn it on again).
