The water outlet of the solar water heater is at the bottom of the water storage barrel. Generally, there is no sediment inside, so there is no need to drain the wastewater. The outlet pipe of an electric water heater is usually located at the top of the water storage barrel. When using it, the water inlet must be opened to expel hot water. There is sediment inside that is difficult to get out, so the. wastewater should be drained regularly.
Wastewater disposal steps:
1. Unplug the power plug, wrap the plug with leakage protection and place it on the water heater body. Seal the socket. To prevent water from entering.
2. Close the water inlet tap and remove the mixing tap.
3. First place a large bucket under the sewage outlet, remove the red plastic cover outside the water outletnext to the water outlet pipe and use a wrench to remove the waste water outlet nut. At this time, all the water from the water heater flows into the bucket.
4. When I saw that the running water no longer had pressure and the water was starting to change color, I changed the connection on the bucket. It didn't take long for the sewage to flow out and the water in the electric water heater to drain.
5. Pour the cleaning solution directly from the sewage outlet with a syringe or the like, plug in the sewage outlet again, plug in the water outlet, connect the water inlet pipe and add about 3 half buckets Water. And the process of adding water is sometimes full of water and sometimes little water.
6. After about 30 minutes, open the drain outlet to drain the water and add water several times to flush the water heater three times.
7. Reinstall the water heater and replace the cap. Thisconcludes the wastewater cleaning work.
