Temptrol Shower Valve Troubleshooting
Why can I get only all hot or all cold water out of the Temptrol shower valve?
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. 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.
