The size of PPR pipes you choose will vary depending on the type of house. So, during home renovation, how do you select the right PPR pipes?
Common specifications of PPR pipes currently available on the market include: DN15 (4-fen pipe), DN20 (6-fen pipe), DN25 (1-inch pipe), DN32 (1.25-inch pipe), DN40 (1.5-inch pipe), DN50 (2-inch pipe), DN65 (2.5-inch pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), and DN250 (10-inch pipe), among others.
4-inch pipe / 6-inch pipe
In home decoration, the most commonly used PPR pipe diameters are 20 mm and 25 mm (commonly referred to as 4-inch pipe and 6-inch pipe, respectively), with the 4-inch pipe being used more frequently.
Generally, 6-inch pipes are used for the main line, while 4-inch pipes are used for branch lines. The S3.2 and S2.5 hot-water pipes are household hot-water piping systems available in both standard PPR and antibacterial PPR versions. If these pipes are to be used for heating systems, the standard PPR version is sufficient. The S4 and S5 pipes are designed for both cold and hot water (PPR pipes are specifically categorized into cold- and hot-water types, with varying wall thicknesses). Cold-water pipes cannot be used as hot-water pipes. A simple way to distinguish between cold- and hot-water pipes is that the hot-water pipe is marked with a red line. Nowadays, many home renovations opt for using only hot-water pipes throughout the entire system.
Sixth-level management
If your home isn't a villa, a 4-inch water pipe will suffice. Only if your home is a villa with multiple bathrooms or if you live on a high floor in an apartment building—where water pressure might be low—is it worth considering a 6-inch pipe, since water pressure varies. To put it simply, think about the pressure of the water: When you turn on the faucet and feel it with your hand, you’ll notice that the force with which the water hits your hand differs depending on whether you open the faucet halfway or all the way. If the water comes out with considerable force when you turn on the faucet, that indicates high water pressure. On the other hand, if the water flow is weak, it means the water pressure is too low. If only one person in your household uses water, a 4-inch pipe should still work fine. But if several people are using the faucet at the same time, the water supply will definitely fall short. In such cases, you might want to consider upgrading to a 6-inch pipe.
