ppr pipeline specifications, we usually heard that there are 4 branch and branch. 4. Outer diameter of pipe 20mm, 6. Outer diameter of pipe 25mm. In actual use, the water flow of the 6 branch pipe is a little larger than that of the 4 branch pipe. The main pipe is more than 6 pipes, and the branch pipe is more than 4 pipes. Water flow is not the greater the better, otherwise it will cause the waste of water resources
The LAYING OF ppr pipeline should choose water pipe according to the actual situation to go top or go low. The following are some advantages and disadvantages of the comparison: go to the top: the problem is found early, it is also convenient to do the ground waterproof of the bathroom, once there is a leakage situation, it will not affect the downstairs neighbors: but there are also the problem of laborious construction, and maintenance may need to remove the ceiling. Go: save labor, in the work and pipe to save a cost; Leakage is relatively difficult to find, and in the circuit also go to the case may cause circuit failure; It is not easy to find the leakage point during maintenance, which may cause extensive damage; It also tends to cause neighborhood disputes
