With the improvement of living standards, we have higher and higher requirements for hot water comfort, among which the hot water circulation system at home is no longer only a large house, and this function is also valued in ordinary families
1. If you want to use the hot water circulation function in an old house or a house that has been renovated, you can only find the hot and cold water valve interface under the farthest basin and install a check valve between them; When installing a check valve, the arrow on its surface must be directed towards the cold water end. In this way, the cold water pipe is borrowed to temporarily do the hot water return pipe function, which has great drawbacks.
2. In the case of a newly renovated house, if the length of the hot water branch is less than 3 meters, I recommend making the farthest hot water pipe position, connecting a hot water pipe back to the position of the water heater.
On the contrary, you can start from the hot water pipe of the water heater, connect all the hot water points in the home in series, and finally connect a hot water pipe from the farthest hot water point to the water heater.
The above is the installation method of the hot water circulation pipe at home, and we must pay attention to the thermal insulation treatment of the hot water pipe and the circulation pipe; Among them, the old house has increased the way of arranging hot water circulation pipes, and you must pay attention to the quality of its water pipes, otherwise it is easy to burst the pipe, please be cautious.
