(1) Because the quality of the solar water outlet pipe is uneven, gloves must be worn during disassembly to ensure that the water outlet pipe will not break. Thick cotton gloves are needed, and then some detergent is applied to the outlet pipe for lubrication.

(2) Then hold the outlet pipe from the lower part of the pipeline by hand, adjust the angle to aim at the hole of the water tank, push it in hard, grasp the strength, feel the progress, then rotate it left and right to lubricate the joint between the two, and then slowly pull it out through rotation until the outlet pipe is pulled out.

(3) In the process of demolition, if the old head is not needed, the method of destruction can be adopted, and the head can be directly sawed with an iron saw.

Extended data:

1, the outlet pipe of solar water heater can be directly pulled out if it is connected with silicone sealing ring. However, it is recommended not to pull it out, because it is very easy to leak after being pulled out and installed.

2. Generally, there are two solar water pipes, one hot water pipe and one overflow pipe. The first one is connected to the indoor water mixing valve, which generally has the functions of supplying water and regulating cold and hot water. The second one should be connected directly from the solar overflow and placed next to the indoor floor drain.

3. Solar water heater is a device that converts solar energy into heat energy and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production.
