How to solve the problem of gas water heater automatically starting once after the automatic flushin

Turn down the pressure of the faucet in the toilet flush. My boiler will automatically start at the beginning, and the hydropower master and boiler staff can't find any problems, so they can adjust the vacancy themselves.

Installing a check valve at the inlet pipe of the water heater solves the problem.

I found the reason!! There are 2 ports for the water inlet of the water heater, the return water must be equipped with a one-way DU valve here, and the cold water inlet must also be equipped with a one-way valve DAO

That's it, because the pressure fluctuation of the toilet pump causes the water heater to think that there is a water flow action, so the toilet starts as soon as the water heater is pumped. To sum up: the port where the cold water comes out (not the end of the water heater that enters the cold water, but the end of the cold water switch valve) is equipped with a check valve.
