Is there a one-to-one correspondence between the water inlet and return water valves of the water distributor?

There is a one-to-one correspondence between the inlet and return valves of the water distributor. The red valve indicates the switch of the water inlet pipe, and the blue valve indicates the switch of the water outlet pipe is on both sides of the pipe, so it can be easily distinguished by color. Common water separator materials on the market include copper, stainless steel and other synthetic materials. The price and heating performance are different, so when choosing a water separator, you should choose the appropriate material for the water separator according to your own heating needs to avoid affecting future use.
