If the Symmons Control Unit valve leaks when shut off, it's likely due to worn hot and cold washers or foreign matter (like dirt or chips) lodged between the washers and seat surfaces. Replace the washers using the TA-9 washer repair kit and replace the hot and cold seats using the TA-4 hot/cold seat repair kit.
Why does Symmons Temptrol S261BODY Control Unit deliver hot water when initially opened, turning colder when rotating the handle?
This issue occurs because the valve is piped incorrectly. The hot supply is connected to the valve’s cold inlet, and the cold supply is connected to the hot inlet. If the piping is accessible, correct the connections to the valve. If not, order a T-108 reverse seat and tool kit. Older installations may also require replacing the TA-4 hot/cold seat repair kit.
What to do if the Symmons Temptrol S261BODY temperature handle affects water volume?
If the temperature control handle affects water volume, the pressure-balancing piston in the spindle assembly is likely restricted by foreign matter. Open the valve halfway, remove the handle, and tap the spindle with a plastic hammer. Check the water pressure balancing piston in the control spindle (refer to the service instructions). Consider replacing the TA-10 flow control spindle.
Why does Symmons Temptrol S261BODY temperature reduce gradually during use?
The gradual reduction in temperature during use indicates an overdraw on the hot water supply (i.e., running out of hot water). Reduce the maximum flow by using the volume control adjustment on the valve or showerhead. This will allow a longer period of use before overdrawing the hot water supply.
What causes Symmons Temptrol S261BODY Control Unit to deliver little hot water, but sufficient cold, or the reverse?
This issue is caused by an overdraw on the hot water supply (i.e., running out of hot water). Reduce the maximum flow by using the volume control adjustment on the valve or showerhead. This will allow a longer period of use before overdrawing the hot water supply.
Why does Symmons Temptrol S261BODY temperature vary without moving the handle?
The temperature variation without moving the handle indicates an overdraw on the hot water supply (i.e., running out of hot water). Reduce the maximum flow by using the volume control adjustment on the valve or showerhead. This will allow a longer period of use before overdrawing the hot water supply.
How to fix Symmons Temptrol S261BODY that will not pass water?
The valve will not pass water if both the hot and cold water supplies are not turned on. Turn on both supplies, as the valve requires both hot and cold water pressure to operate.
