2, the water pipe is recommended to use the selection of PPR pipe. PPR pipe is non-toxic, lightweight, pressure, corrosion resistance, easy to construct, can be used as both cold and hot water pipe. Due to the interface using heat fusion technology, the pipe is completely fused together, there will be no aging leakage phenomenon, and the price is moderate. But PVC due to its own material will melt away when it meets hot water, absolutely can not be used for hot water pipe.
3, threading pipe should be flame-retardant PVC line pipe, with a foot lightly stepped on the line pipe should not be flat. All kinds of sockets should have, a little more, especially in the living room and bedroom.
