Can the tap water plastic pipe connect with the old water pipe?
SureYou can buy one with a convertible head.NamelyOne end is PPR or PVC and the other end is stainless steel.You go to the hardware store and ask the boss. Say to water transfer head (specific size look at do). Say "PPR" or "PVC" to your boss. The other end is made of stainless steelBut you have to make sure. Stainless steel part. Is it an inner tooth or an external tooth?. Otherwise, I bought the wrong one.. Either end is an outer tooth or both are internal teeth. It can't be answered. It's like a screw and a screw cap.
The tap water plastic pipe can be connected with the old water pipe.Plastic water pipes and iron pipes need to be connected with external thread. Buy a double headed nut (with the same thread specifications) hose short connection, the nuts are screwed in the plastic water pipe and iron pipe at both ends, you can complete the connection work. Convenient and easy to save and easy to use.
