Home decoration PPR pipes are genlly in charge

The main ones used in home decoration are 20mm (PPR is 4 in charge, which is different from galvanized pipe) and 25mm (PPR is 6 in charge, which is different from galvanized pipe). Among them, 20mm is used more. If the economy permits, we recommend using PPR pipes with an outer diameter of 25 mm, especially the cold water pipes for water intake, because modern households are highly concentrated and have more and more water appliances. At the same time, the probability of water consumption is very high. Reduce the trouble of low water pressure and low water flow.
