Leaking Delta bathroom facet

should not be necessary to get behind the shower stall as there should be a hole big enough to remove /replace the facet insert
call a plumber in as it may be corroded in place and may require specialist tools for the job

take the set screw out and repair the plastic washers inside it

the possible cartridges you can replace are listed on this pdf

Sometimes, 'grit' (or something) can get caught in the cartridge... preventing it from closing completely.

Delta's tech support people might be able to talk you through 'flushing' the valve:

DELTA: 1-800-345-3358

If that doesn't fix it, Delta will probably be willing to replace the cartridge for you.

Make sure the area below where you replaced that part is free of scale and is not damaged in any way. Scuffs, scale and dirt will caused your leaking.

Hi,
You can purchase a replacement cartridge for that... most hardware stores or places like Home Depot or Lowe's will have them. Take in the old acrtridge or the model of thefaucet. Some of them need a special puller to get the old cartridge out..

You would have to open up your drywall, cut and re-solder a new single handle faucet. An easier approach could be to shutting off your water supply, draining the lines in your bathroom from someplace below, and then trying to fix the bad soldered joint if you know how to do so.
I hope this helped.

It is possible to fix this yourself, but realize that the valve on the tub/shower is holding back huge amounts of water under high pressure. Make sure you know how to shut off the water to the house, and make sure you do it. You'll need to get the proper parts at a local hardware store and have good understanding of what you're doing.

turn of both water supply under the sink.
there is a small red/blue plastic cap at about 45 degree to the underside of the handle. you need a allen key screw driver to lossen it, then pull up the handle. unscrew the lock cap on top of the facet body. left out the cartirdge and make sure there are two "O" ring at the butom of the cartridge is out of the focet body. install in reverse.

Replace the cartridge even if its new. The vibrating is from the internal workings of the stem. It also effects the volume of water.


good luck, Phil
