Fix Bath/Shower faucet leak

I had a leaky shower valve that needed it's washer replaced. The fixtures are NOT from a major manufacturer as I could not find a manufacturer's name or logo on any part. So, if you have a bath/shower fixture like mine, this might be helpful.

Hope this helps someone out there!!

I have these in 2 baths and 1 shower - 6 valves.

All parts of one valve - removal steps.

The shower only runs hot water no matter where the handle is turned...even on the cold setting.

You need to replace the mixing valve. It's not terribly hard to do, if you have some tools and, if the valve is not stuck in the fixture. Here's a video on how to replace it. Take note of how the tabs on the valve are positioned so you can put it in the same way it came out. If cold and hot water are reversed, you need to take valve back out and rotate 180 deg. and put back in:
This is assuming you have hot water elsewhere in the house and not ot the shower. Check to make sure you have hot water at other faucets.

I want to replace an old single handle builders no-name shower, about 15 years old with a gromhix 34436 unit. My shower is tile. What steps should be expected? Is this practical?

Usually a shower stall will boarder a wall where you can access the fixture by cutting a hole in a boaring wall to get at it. If it boarders a closet or someplace thats not conspicuos, there may already be an access hole. Once you have access to the old fixture, you can remove it and, as long as the new fixture is the same size or larger, it shouldn't be that much of a problem. You may have to make the hole in the tile larger but, you should be able to do that with a 90 deg. grinder. Usually most, if not all, shower valve(single) have pretty much the same configuration. If your pies look to be in good condition, you should be able to work with piecing in the new fixture. If you cannot access the fixture from the back sie, well, thats a different story and, alo of work in redoing tile you probably won't be able to match and, a little bit of drywall work but, if you only cut the hole a sbig a you need it,you use some sort of fired decorative tile to cover the repairs spot. It's up to you.

shower gets too hot the thermostat does not seem to control the heat

On all showers, there is a mixing valve behind the wall. With out knowing which type of faucet I can't give proper details, but generally if has just started on its own to do that, the vavle either needs cleaning or replacement. Most valve manufacturers offer lifetime replacement parts, I know Koehler and American Standard do, so parts shouldn't be an issue. They can also walk you through minor repairs as well. If you need further assistance let me know and if I can get the model number of your fixture, maybe download the schematics, and assist you more.

I have no pressure and no water coming from cold water ( tub) This setup has two handles, one for hot, one for cold. It is not the handle - it's tight. Its in a manufactured home built in 84, and I bet the fixture is original . No brand name on the face of it

Two possibilities come to mind. 1. The shut off valve (in the wall under the fixture) is almost closed. 2. Trash in the valve assembly or a broken seal. Turn off the water at the shut off valve and remove the handle and stem from the fixture. Clean and replace anything broken. You could even open the shut off valve for a second to flush any junk out of the fixture. Reassemble, turn water back on, and test. This should solve your problem.

water flowing through power shower on or off

Sounds like you either have a very leaky washer or the shower cartridge is stuck. You may have to turn off the water to the house since many shower valves do not have separate isolation valves.
