    Bathroom shower
    My question is the bath room up stairs shower or tub the water will only get to approx, 100 degrees if I move the lever it gets cold and some times the water goes from warm to cold. It's a Symmons Temptrol valve about six years old and I have replaced the stem already.

    Speedball will be much more informative if it's a valve issue, but have you already checked the temp setting on the water tank? Could be that it's just set too low.

    Hey Pappa,
    Try this.

    What is a handle limit stop and how do I set or adjust it?

    All Symmons pressure-balancing shower valves come equipped with a handle limit stop to set the handle rotation. The limit stop is used to limit the valve handle from being turned to excessively hot water discharge temperatures. CAUTION: Never remove this screw without turning off the hot and cold water supplies.


    To set the shower valve handle limit stop, remove the screw holding on 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 on the valve stem (loose) and open the valve turning the handle until the maximum desired position is reached.
    Turn the screw in a clockwise direction until it seats to set the handle limit stop.
    Shut off the valve and re-attach dome and handle.

    Also it sounds like The pressure-balancing piston housed in the spindle has become blocked from free movement by foreign matter. Open the valve to the half way position, remove the handle and firmly tap end of spindle (TA-10) with a plastic or wooden hammer. If the problem is not solved, remove the spindle assembly (TA-10) from valve. Click here for disassembly instructions. After spindle assembly has been removed from valve, tap the handle end against a solid object to free the piston. Soaking the entire piston assembly in household vinegar will also help free the piston. If this does not solve the problem replace with a new TA-10 spindle.

    If that don't get it click on back. Tom
