What should I do if the thread of the plastic bolt at the water heater drain is broken?

The vent of the water heater consists of two parts, one part stainless steel and one part plastic. The plastic part is a manual control switch. Generally, it is not used. So if it's broken, it doesn't need to be dealt with. If manual treatment is required, only one pressure relief valve can be replaced.

The water heater safety valve is suitable for electric water heaters and air energy water heaters, and has the functions of check valve and pressure relief valve, which can prevent the backflow of water entering the electric water heater and discharge the excess pressure when the pressure of the inner tank of the electric water heater is high, so as to ensure the life of the inner tank and avoid the occurrence of bile burst accidents.

It is divided into water inlet cavity, water outlet cavity and safety cavity, the safety cavity has a drainage hole, a check valve core, an external adjusting spring is placed in the water outlet cavity, and the limiting limit is limited by an adjusting limiting sheet, an elastic cushion, a safety valve core and a drainage rod are placed in the safety cavity, a safety pressure regulating spring is placed in the safety cavity, the adjusting cover is screwed into the safety cavity through the drainage rod, and there is a protective cover plate outside, and the drainage lug is connected to the drainage lug at the end of the drainage rod, and the drainage lug is buckled with a protective buckle, and the protective buckle is fixed on the drainage hole seat with a drainage pipe joint.

The pressure relief and exhaust are fully automatic, no manual work is required. If the water heater is coming out of hot water normally. You don't need to replace it. If the hot water does not come out, or if the pressure relief port is leaking, replace it.

If the thread of the plastic bolt at the water heater drain is broken, you can use a drill bit that is slightly thinner than the screw hole to hit it, if the plastic inside the buckle is damaged, it is very easy to get it down. Of course, you need to clean the water in the water heater first.

Water inlet, outlet, sewage outlet, of which the inlet and outlet are mostly 4 points of outer wire. When manufacturers make electric water heaters, there are two ways to connect the inner tank with the water inlet or the water outlet opening: welding and screws.

Therefore, if the outlet or inlet of the electric water heater is broken, the kind of wire that can be unscrewed off is easy to replace, while the inlet and outlet that is welded to the inner tank is difficult to deal with. Usually this kind of problem occurs, we will use winding raw material tape, padded silicone ring to remedy, in addition, if it is a wire mouth problem, you can use a wire puller to deal with it, there is also a good effect.

You can also try the following solutions: 1. Use a movable wrench or a socket wrench of appropriate size to unscrew the plug of the sewage outlet. 2. When unscrewing the sewage plug, it is best to have another person fix the water heater cylinder with both hands next to it, so as to avoid rust due to rust of the sewage plug and the wrench when the wrench is forcefully wrenched, causing deformation and falling off of the hanging plate or expansion bolt behind the water heater, causing damage to the water heater. The force of the wrench should not be too strong or too fast, and it should be used slowly.

After unscrewing the plug of the rising sewage outlet, there will be more water flowing out, pay attention to the water not to spray the other electronic control parts of the water heater, and do not cause damage to other household appliances. 3. After unscrewing the sewage outlet plug to discharge the sewage, it is best to open the water heater tap water inlet aquarium laughing shed pipe valve, and flush the water heater in the gut, which can have a better sewage effect.

Take a 4-point inner and outer joint:

Apply the water pipe sealant, gently screw into the broken water inlet, and use a new thread after curing.
