What should I do if the toilet wrench switch doesn't return?

If the toilet wrench switch does not return, it may be due to the following reasons:

1. Wrench switch is old: the toilet wrench switch may be worn out after being used for a long time, making it unable to completely return to its original position. At this point, it is necessary to replace a new set of wrench switches to ensure their normal operation.

2. Throttle is blocked: If there is too much garbage and dirt in the throttle, the water gate will not be completely closed. In this case, it is necessary to remove the throttle valve and clean it, and check whether the water gate works normally.

3. Watergate nozzle damage: If the watergate nozzle is damaged, the watergate cannot be completely closed. This will lead to the stop and waste of water flow. In this case, it is necessary to replace the new water gate nozzle to ensure that the problem is solved.

4. Rudder damage: Rudder is an important part of Watergate. If the rudder is damaged, the sluice will not be completely closed. In this case, it is necessary to replace a new rudder to ensure that the problem is solved.

In short, if the toilet wrench switch does not return, be sure to pay attention to safety and check and repair after the water is cut off. If you can't solve the problem yourself, you'd better hire professionals to deal with it, so as to ensure that the problem is completely solved and prevent safety accidents.
