New plastic pipes
 

In my house inveterate pipe and I would like to change them. Locksmiths recommend me to install, plastic pipe, but I do not really hope their resistance to heat and cold. But Locksmith convinced me Thu they are much stronger than metallic pipe. This is so if someone also used plastic pipes please share opinions

PVC (or CPVC for hot water pipe) plastic water pipes are very common in the US. The way they glue together is a lot easier than threaded metal pipe, they're pretty inexpensive, and they hold up pretty well.

a very big thank you. I have already installed plastic tubes and they work very well, and as you said not expensive cost

PVC is best one...
