Yes, easily! Simply replace the hot and cold washer parts using a genuine Symmons TA-9 Washer Repair Kit. It has everything you’ll need, including installation instructions. Don’t forget to shut off the water first!

In this case, the pressure-balancing piston that moves inside the main TA-10 spindle has become jammed with some sort of debris, like minerals or pieces of dirt or solder. A good first step is to open the valve to the halfway position, remove the handle, and firmly tap end of spindle with a plastic or wooden hammer.

If the issue remains, shut the water off and remove the spindle assembly from valve, and then tap the handle end against a solid object to free the piston. Then, shake the spindle–you should hear the distinct “click-clack” of the piston moving freely.

If the piston appears to be blocked by minerals, soak the entire piston assembly in household white vinegar. If possible, flush or clean the inside of the valve body before reassembly.

If these steps do not solve the problem, replace the spindle with a new TA-10 spindle.

*Turn off the water to the valve before proceeding!

**Before removing the handle, open the valve as if you were going to take a normal shower (approximately half a turn).

CAUTION: Failure to open the valve before removing the cap assembly (TA-12A) will result in damage to the cap and spindle.

Removing valve trim

1. Remove the plug button (T-33) from the temperature control handle (T-31).
2. Remove the handle screw (T-32) and remove the temperature control handle.
3. Remove the two escutcheon screws (T-28). Remove the dial [T-29(A,B,C)] and escutcheon (T-27).
4. Remove the dome cover (T-19/20) by unscrewing in a counter-clockwise direction.

Opening valve

1. Remove the cap assembly by using a wrench and turning in a counter-clockwise direction, the spindle assembly will come out with it. Separate the cap from the spindle by unscrewing the cap in a counter-clockwise direction.
   Replacing washers or spindle
2. At this point you can rebuild or replace the spindle. To rebuild use the TA-9 washer kit. Hint: Place the handle on the spindle so that you can hold it stationary. Remove the hot washer screw (T-5) and the hot washer (T-6). Remove the cold washer (T-8) by using adjustable pliers turning counter-clockwise on the cold washer retainer (T-7).
   Reverse the above steps to reassemble the spindle with the new parts.

Replacing seats

1. To replace the seats you will need to use the seat removal tools (T-35A/B) and TA-4 seat kit. Insert the larger seat tool (T-35A) into the valve until it engages in the notches of larger cold seat near top of valve. CAUTION: Use extreme care to make sure the wrench is engaged into the notches in order to prevent stripping of the notches. Remove by unthreading in a counter-clockwise direction.
2. Next insert the smaller tool (T-35B) until it engages in the small hot seat located at the back of the valve. Remove by unthreading in a counter-clockwise direction.
3. Reassemble with new seats from TA-4 kit, reversing steps 9-8.
4. Tighten both seats to 15 foot-pounds of torque.
5. Reverse the above steps 5-1 to reassemble your valve and trim. Be sure the spindle assembly is drawn close to the cap before screwing the cap back into the valve. CAUTION: Failure to do this will cause damage to the cap and spindle.
