How can I stop a leaky Delta sink faucet?

Question

We have a fairly new Delta faucet, and it has a slow drip that can't be stopped. Sometimes it is even a small steady stream. It has the one lever that goes to the right or left, depending on whether you want hot or cold water. I assume these are all washerless, so I don't know where to start. I haven't taken it apart yet. Would like some answers before I attempt that. A professional licensed plumber installed it. It also has the hand-held faucet part that comes out of the mount and switches to a sprayer. I'd like to fix it myself if possible.

Answer 1

Delta faucets have replaceable parts under the handle



you need to remove the handle, you will need an allen wrench of correct size

pull the handle off

next you need to unscrew the cap surrounding the stem that the handle attaches to

use a wrench(I'd wrap a towel around the cap so you don't scratch the chrome)

under this is a plastic and rubber gasket over a stainless stem

remove these and there will be two black rubber gaskets on springs where the hot & cold water enter

I'd use the allen wrench to pop these out---these are what are causing the leak



you should be able to buy these replacement parts at you local home improvement store or local Delta wholesaler



when installing these new pieces, align them on the allen wrench so you can guide them into there respective holes

they then need to be pressed down so the the rubber caps are tight on the springs and not sticking up to far (check the old ones for reference before removing them)

then install the stainless stem, it will have a slot in the side that must be aligned on a small tit inside the cavity

the plastic and rubber gasket goes on top, this has a plastic tit that must be aligned in a slot where the threads for the cap are

then slowly screw the cap on so as not to turn the stem or plastic piece

tighten with a wrench, reinstall the handle and you should be back in business

Unfortunately there are many types of faucets and depending on the type there are different failure mechanisms. Some can even leak in multiple ways. If you have the will to save money you can how to do it. 1) Shutting off the cold water going to the faucet is the first step. 2) Taking off any decorative cap is the second step. If there is no visible screw, the screw must be under a decorative piece. Use something very thin like a knife blade to get under the decorative piece and very carefully pry the piece off (Use care so you don't break the knife as that could be dangerous. also, don't pry with the tip of the knife. You are almost certain to break or bend it.) If you can get the cap slightly off you can then switch to a screwdriver. You will have to work your way around the parameter of the piece as you pry when you do this. 3) Once off, remove the screw that you will see and then wiggle the decorative valve handle off. 4) once the handle is off you will see a piece that will require a wrench to remove. Screw it counter clockwise until it is off. 5) Pull out the inerds of the valve and inspect all surfaces closely. You may need to do some disassembly of what you have pulled. Try to determine exactly how the valve seals when it closes, and what surface it seals on. Inspect those surfaces closely. I have some valve plugs for older Kohler faucets where once they start leaking, the flowing water cuts a groove in the sealing surface. If you find metal that has been eaten by water flow the best thing to do is replace the part. Homestores carry some parts, but others you may have to order off of the internet, or find a vendor of that valve in your area that sells parts for your specific valve. Good Luck!

Answer 3

There is no excuse for this faucet leaking already, understanding that if you screw it up, the plumber has no liability, here goes. Turn off water ,Allen wrench loosens screw under handle, slide handle off; adjustment nut[plastic nut with cutouts] could be your only problem, tap it clockwise until it seems snug, try faucet. No; loosen adjustment nut, remove serrated metal nut, keep parts in order of replacement; plastic shroud, rubber gasket, Do Not pull on the stem, there is a nipple holding the stem and ball in place, angle the stem sideways to clear the nipple. Two springs and seats[washers] replace. reverse order, making sure not to overtighten metal nut and plastic adjustment.

Answer 4

Delta usually have a warranty if its that new. If it was old I would say you need to change out some of the O-rings in it. Even though its washer-less...it has some O-rings and other rubber parts that wear out. Call the plumber that put it in and tell him its leaking...maybe he'll come out and replace it...that is if he stands behind his work.

Answer 5

It sounds like you have a bad washer or seat inside the valve. Take the model # to store and pick up a repair kit. They come with instuctions and arn't to hard to do. Good Luck
