1. If the water heater liner leaks, it is recommended to use a sealing ring to remedy it, which can alleviate the liner leakage. If the coating leak is serious, it is recommended to do this. replace the coating directly.
2. Most of the causes of water leakage in domestic water heaters are sealing problems of the connection between the heating tube and the inner tank, it appears from subsequent maintenance that this is usually caused. to the connection between the heating tube base flange and the inner tank. The sealing ring between the two parts is broken. To solve the leaking problem, the sealing ring must be replaced.
3. When the water heater boils the water, the water will expand due to heat and the expanded water will be discharged from the nozzle, but there is very little water in this part. terms of product structure.
4. If the tank is damaged and causes a leakwater tank, you need to purchase the same model water tank and find a professional installer to reinstall it.
5. Tap water pressure is high. If there is a lot of water at the nozzle when boiling water, you can contact maintenance personnel to check it to avoid possible blockage somewhere in the pipeline.
6. Water is leaking from the small hole in the safety valve. Reason: The tap water pressure is too high, exceeding 0.7 MPa (safety valve pressure relief). The steam pressure in the water heater exceeds the relief pressure of the valve and a small amount of water flows out. It is normal to install a pressure reducer in front of the water heater inlet or to leave the water outlet open.
7. If the silicone pad at the connection point of the heating tube becomes old, it should be replaced.
8. If the water heater safety valve is leaking, first check if it happens when the water heater is at high temperature. If this is the case, the problem is not serious and it is normal, but a water leak when the temperature is low proves that there is a problem with the safety valve itself and that it must be replaced.
9. Carefully check the leak point to see if it is leaking from the water heater body, such as the safety valve, mixing valve, sewage outlet and other groups of valves and connecting pipes. If the inner tank is not leaking, you can replace the affected accessories or increase the tightening torque.
10. Hot water leaks are relatively normal. If cold water is also leaking, the water heater should be inspected.
How to replace the solar heating rod
1. Turn off the water supply and remove the faucet handle.
2. Unscrew the packing nut and remove the sealing ring.
3. Install a new seal ring. If linear sealant is used, wrap it around the valve core several times. If it is a leather pad, just put it on directly.
3. Insert the silicone ring into the insulating bucket. Hold the silicone ring and look at the edge. There is a groove in the middle of the silicone ring. On both sides of the groove, one side should be. be thicker and the outer circle larger. The outer circle should be thinner and smaller. The side with the thinner side and smaller outer circle faces inward when placed at the water tank suction pipe hole. The groove should be completely closed with the stainless steel hole visible at the mouth of the water tank suction pipe.
4. Repeat steps on the top surface of each tube. Next comes intubation. When intubating, wetFirst cover the windshield (usually a black rubber ring between the vacuum tube and the outer wall of the water tank) with clean water and place it on the open top end of the vacuum tube. ?
5. Moisten the installed silicone ring with laundry detergent or expose it to the sun. It can fill the water and let the water flow out of the vacuum tube hole.
6. Hold the tail of the vacuum tube with one hand to protect the end of the tail, and hold 1/3 of the vacuum tube with the other hand. Use uniform force and keep the direction of the force consistent with the direction. Coaxial line of the tube mouth. Insert the vacuum tube into the water tank. At this point you can insert an additional section into the vacuum tube hole. Once the tail of the vacuum tube is aligned with the protective bracket, pull it out. until the vacuum tube and the protective bracket are firmly fixed, then place the windshield ring firmlyis against the exterior wall of the water tank.
There are two types of electric heating rods. They are identical to the incandescent bulbs we use. One is bayonet type and the other is wire type.
Drain the water in the water tank, open the side cover of the water tank, and remove the thermal insulation polyurethane in the lower third of the side cover (the connection point of the electricity). heating wire) (reserve it for filling), usually a hex nut mouth. Use an adjustable wrench to turn it clockwise or counterclockwise. If it is a bayonet nut, it will fall out when you remove it. it's a threaded nut, it's like twisting a screw. Unscrew it, then replace it with a new one (remember to add a silicone gasket, otherwise it will leak), connect the wires and fill in the insulating material you juste fill out. dug
Remember that there are two key points A: 1. Find out if it is an electric heater with a wired port or a bayonet, and remember to Align the sealed silicone gasket 2. When wiring, remember to separate the neutral, live and ground wires. Some electric heaters have leakage protection probes, which must also be well connected.
