1. Installation steps
When installing the 304 stainless steel red and blue wheel angle valve for home user, follow the installation diagram or operation video provided with the product purchase step by step. Generally, 304 stainless steel red and blue wheel angle valves for home user include the following installation steps:
① Close the water valve at the front end where the angle valve is installed, and clean up the dirt and residual water at the interface.
② Clean the 304 stainless steel red and blue wheel angle valve for home user, keep the inside and outside of the angle valve clean, wrap the water inlet end of the angle valve with raw material tape layer by layer, and wrap as many times as possible under the condition of size permitting.
③ Align the wound angle valve with the installation port of the water inlet angle valve (usually set on the wall), and slowly screw it into the wall with the aid of hands or tools, so that the base of the inlet end is flat or parallel to the wall. And make sure the orientation of the handle and water outlet is correct and without deviation.
④ Connect the water pipe to the water outlet, open the water valve, check whether the 304 stainless steel red and blue wheel angle valve for home user is leaking, and how sensitive the adjustment is. If there is a problem, close the water valve for inspection and adjustment.

2. Overhaul and maintenance
During use, the 304 stainless steel red and blue wheel angle valve for home user may also fail. The failure of the angle valve is generally manifested as water leakage, difficult adjustment, etc., usually due to the long service time and material stress failure, and it should be repaired in time.
In case of water leakage, first close the valve, take out the 304 stainless steel red and blue wheel angle valve for home user, and check whether there are cracks or damage in the water inlet joint. If not, on the one hand, it may be caused by the wear of the raw material belt, and you can try to wind it a few more times at the joint; on the other hand, it may be other places, such as the problem at the handle/spool. At this time, the leaking point is usually near the handle. , you can consider replacing the new valve core, and then open the water valve for testing. Of course, direct replacement is also possible.
