In addition, the strength test and sealing test should be carried out on the check valve, and it can be installed and used only after it is confirmed to be qualified.
2、If you want to install the check valve correctly, the installation height of the check valve, the direction of the inlet and outlet of the water flow, etc. must comply with the relevant installation specifications, and the flow direction of the internal medium should be the same as the direction of the arrow marked on the check valve. And the connection position must be tight and firm. 

3、When installing the check valve, first,you should observe the two ends of the check valve in detail, then find out the water inlet port of the check valve, and then connect the water inlet port of the check valve and the water outlet port of the water pipe together. The check valve will operates when water flows from the inlet port of the check valve.
4、The water inlet port of the check valve is usually located at the lower position of the check valve, and the water outlet port of the check valve is generally located at the upper position of the check valve. When the water pressure of the water flowing into the check valve exceeds a certain value, the valve of the check valve will automatically open, and then water will flow out of the water outlet port of the check valve.

5、When the water pressure of the water flowing into the check valve is lower than a certain value, the phenomenon of backflow of water will occur in the check valve, and the valve of the check valve will also be automatically closed, and no water will flow out of the water outlet port. Through the above water flow phenomena, it can be detected whether the check valve is installed correctly.
