There is a screeching sound at the end of the toilet bowl flooding? What the reason

There is a screeching sound at the end of the toilet bowl filling the water, which is the sound of creating air currents in a small gap. The water pressure is high, and when the float valve is about to be closed, it is enough to close the toilet inlet valve by half to reduce the water pressure.

Routine maintenance of the toilet:

The user cleans the toilet bowl at least once a week.

If the water source in the user's location is hard water, it is necessary to keep the outlet hole clean.

Frequent flipping of the toilet seat can cause the fastening gasket to loosen, tighten the seat nut.

Do not knock or step on the pottery sanitary ware.

Close the toilet seat and do not slam it.

When the detergent is poured into the toilet, do not turn it off immediately, but turn it off after rinsing it with water.

Do not use high-temperature water to scald the sanitary ware.

The inlet water pressure is too large, and there is a large friction with the four walls of the pipeline, resulting in a large noise.

Solution: You can close the inlet valves to reduce the pressure.

The inlet hose is so twisted that there is a lot of friction between the water and the pipe wall, resulting in a loud noise.

Solution: Straighten the hose to reduce friction.

There is a foreign object blocking in the water ingress fittings.

There are small holes in the copper water inlet fittings, which cause howling.

It should be the sound caused by the valve closing and the water flow becoming rapid.

The sound of turning off the water may be broken inside.
