The cold water on my Delta double hand faucet is leaking. I replaced the spring and rubber seat. when I put it back together, i can not turn the water off with the handle. I took the stem assembly out and put it back just like I pulled it out. I also purchased a new stem assembly and that did not fix the problem. I them compared how the stem assemblies for the the cold water and hot water lined up and could not tell a difference. I have to have the alignment wrong. what do I have wrong?

I've installed quite a few of these from the big box stores that leak. There are 2 rubber pieces inside the valve body that act as seats. The seats are what turn the water on and off as you move the handle. These rubbers need to be replaced. You can buy a delta repair kit, which will contain these parts. Where the faucet is new, it might be easier to bring it back

messy ,, but while u had it apart did u turn on the water to see if water would come out at all... we flushed our line and that cleared up the problem.

If it's a Delta-type faucet, disassemble it and make sure that the little rubber "cup" seal is properly seated on the spring and in the seat. It's fairly easy to get one of them in slightly crooked, which will leak like the dickens. If it doesn't want to go into the channel properly, you can use a tiny dab of petroleum jelly (Vaseline) to lubricate it.

Go to delta website, take a picture of faucet with your cell phone and send. They should be able to identify and send you the parts. Meanwhile you'll have to turn water on and off from the emergency shut off valve under the sink. If it looks like the picture, it's probably the rubber seat and spring. If you don't want to wait go to your local "hardware" store. There may be someone there to help you. Bring the stem or cartridge, along with the rubber seat and spring. Don't use cold water while stem is removed. Turn cold off as well to prevent a mishap.

Check outside water pressure to house. Should be 65 - 75 PSI. If good most likely the cartridge. Older faucet, do both sides to prevent future problems. Blade handles? Make sure you get Hot & Cold stems, they turn the opposite way with blade handles. Some cartridges are universal and can be adjusted to work either way. After removing the stem, check with a flashlight in the valve, delta has rubber seats and springs on many of their models. If so, replacement of the rubber seats may do the trick.

Many of these problems develop from poor maintenance on water heaters and high pressure. Water heaters, regulators, safety valves, supply lines, and emergency shut off valves at fixtures should be checked, cleaned and adjusted on an annual basis. Your local expert plumbing contractor should be able to assist you on that.

Hi,
Take the handle off (set screw underneath)
Then turn the top off under the handle....make sure water is off...
then you will find a ball with the handle stem on it....note the position of it and pull it out...
under there are two wets of springs and rubber seats...
pull the right side out and check the hole for a blockage...(dirt or rust)
if none is visible, you may have to unhook the cold water supply hose
and then blow compressed air back through the hole to remove the blockage...
then reassemble...

Here is where to find the manual for your faucet. The only tools you should need are a pair of slip-joint pliars for the main ring and the hex key tool that came with the replacement parts. Remove the handle by loosening the hex screw on the underside. Make sure to turn off the water before you go any further and you will need to turn off both hot and cold.

Remove the dome-shaped cover either by hand or with some pliars.

Pull out the ball with the stem in it and underneath there will be two rubber washers with two springs underneath. Remove the washers and springs and put the new ones in. Put in the new stem (ball with stem) taking care to line up the slot in the side with the nub inside the base. Replace the round washer on top with the triangle hole in it and put the dome shaped cover back on.

Before turning the water on, use the back side of the hex-key tool to tighten the nylon ring that screws down into the dome shaped cover. Put the handle back on and try the faucet, if it moves too hard, loosen the nylon screw a bit, if too loose then tighten it. Once it "feels right" you can reattach the handle and turn the water back on.

I suggest turning on the water slowly and look for leaks. Not as difficult as it sounds.

You will need to remove the cartridge that the screw was attached to and underneath there is a rubber cup washer with a small cone shaped spring. You need to replace the rubber washer which is called a seat and the spring ,then put cartridge and handle back on and you should be good to go. Thank you.

When a Delta Scald Guard will not turn off, more than likely it is because the seats have worn out. Turn off the water supply and open any faucets lower stream of the shower unit. Using an allen key, locate the set c=screw in the handle and back it out. Next,Remove the Phillips screw holding the handle in place.Next turn the retaining ring counter clockwise and pull the catridge out of the faucet.Some catridges have two parts front and back. Behind the back part id two small rubber washers called seats and two springs. Install two new seats and springs and everything else in reverse order.

Not hot water should not exceed 120 degrees. If it does it will continue to melt the seats.

I do believe that Delta guarantees their faucets for life. Go online to get the 800 number and call them, have the model number ready. They actually sent my girlfriend a replacement for her $300 kitchen faucet and also the guts to 2 bathroom faucets. They come with diagrams also. Of course I had to install them, but they stand behind their stuff.
