If the hot and cold tap is opened in the middle position, it actually connects the cold water pipe to the hot water pipe. If the water outlet of the faucet is blocked to prevent water from flowing out, then cold water will flow out. flows through the hot and cold faucet and hot water pipe. Water is added to the solar water tank, but if the water outlet is not blocked, water will generally not be poured into the solar water tank unless the water pressure is very high and the water flow from the water outlet is very low.
I hope to adopt it, thank you
