It could be the simmons valve cartridge. It's happened to us twice over 15 years. Lifetime warranty on the guts of any simmons temptrol, residential use. I called and they just sent it out to me, no questions asked, no cost to me. I'm installing it myself.

It sounds like you have a problem called water hammer. When you shut off a fixture the pipes vibrate loudly or hammer. It is usually associated with one or more fixtures within the home. The easiest way to fix this is to install a water hammer arrester. Check with you local hardware store. If you are not comfortable with soldering copper you may wish to call a local plumber to install the arrester within the existing plumbing system.

Symmons temtrol type A only leaks when water is being used and leaks in the wall. what do i need to do?

If it leaks only when used, the leak is coming from the the lines running to the shower head or faucet (if you have one), or both - the leak will most likely be occurring at a fitting, either where these lines connect to the valve body, or elsewhere along them.

Leaks in the wall space can lead to rot and mold. Best not to use the shower until its fixed. Its a relatively straight-forward repair if you know a bit about plumbing and have an adventurous spirit. If not, I recommend calling a plumber.

How do you internally adjust the hot water setting of a Symmons pressure balancing mixing valve?

  • To set the shower valve handle limit stop, remove the screw holding on to the handle and remove the handle.
  • Remove the round dome cover by turning in a counter-clockwise direction. At this point you will see a small slotted screw head that is visible in the valve cap.
  • Place the handle back on the valve stem (loosely) and open the valve turning the handle until the maximum desired position is reached. This may require turning the limit stop screw (T-34) counter-clockwise (see CAUTION above). To most accurately and safely verify the temperature of the hot water, place a thermometer in a tumbler of water filled from tub outlet.
  • Shut off valve and re-attach dome and handle.

    I have a symmons shower that has barely any hot water and barely any pressure on the hot side?

    Chances are it is a simple blockage.. at least that is the first place to check. In some cases simply removing the handle and tapping on the spindle with a plastic hammer/mallet will dislodge the particle.. or you may need to clean the balancing unit.
    Turn the water supply off.. disasemble the valve and soak in vinegar overnite.. rinse well.. and reasemmble.

    If this doesn't fix it you may need to replace or rebuild the assembly.

    Good luck

    We installed low flow shower heads on a symmons temptrol system and now the showers do not get hot and the temperature flustuates.

    You might want to change out to a different model. The highsierra showerhead company makes a 1.5 gpm showerhead that works well and won't clog. It fits a standard male thread stem so maybe you would need an adaptor.

    Water not warm enough comming from shower. Very hot comming from tap. I think it is a problem with the mixer unit in the shower

    Replace your Tempering valve cartridge.
    Should do the trick.

    This will cost a couple bucks for that cartridge.

    Water not hot at the Symmons Safety Mix valve. Had plenty of hot water before I installed a new hot water heater. Now, it's not as hot. I turned up the temperature to about 130 degrees. Sometimes it is...

    There might have been some sediment that came thru the water line after changing the water heater and got into the mixer valve. You may need to shut off the water and clean out the mixer valve assembly.

    Our shower does not produce hot water. How do I know if the mixing valve is the problem?

    check the anti scold setting if new install is shipped set in cold position if paperwork available will explain how to adjust or their 800 number can explain
