Yes but you have to find the main lines going into your shower and switch them, just tell your guest a head of time or switch the hot cold lables

The flow of cold water is extremely low after replacing the Symmons mixing valve?

You may have installed the cartridge incorrectly. That is reverse flow direction. Please check. Please provide model number of the mixer you have used. It might be on this site.

No shower hot water

does the handle rotate from cold to hot....if it does not seem to go all the way to hot it could have a set limiter under handle that has to be reset so handle will rotate to hot...pull handle and check the setting and see if that works...good luck...

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.

    Hot water slows to a trickle when lever turned to hot. Cold water has pressure. All other faucets in house have pressure

    sounds like you have trash in hot side of value or cartridge...shut off water remove cartridge....check for trash....turn on water slowly to clear lines...may take 2 people to do this 1 to turn water on while other sees if water comes out both ports in value....look in cartridge to see if any clog....if you can get a bucket of soapy water before hand and wash cartridge under soapy water...reinstall and check....if water comes out off both ports without cartridge in...when you reinstall after cleaning it still no may need new cartridge,,,good luck

    Low shower pressure

    1. Is there a water saving feature/washer ?
    2. Was there good pressure before ?
    3. Is there an adjustment at the control valve for how much hot/cold water is being balanced ?
    4. Any debris stuck in valve ?

    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
