Plumbing pipes such as pex copper and pvc are normally used depending on their application and the location in which they are installed.
Galvanized pipe to copper.
Solder the brass half to the copper pipe thread the steel half onto the galvanized steel pipe with teflon tape then join the two together tightly with the joining nut.
Copper plumbing is lead free making it safer than galvanized pipe.
Copper pipe is available in small diameters for installation in tight spaces.
When connecting a copper pipe fitting to a galvanized steel pipe you must use a dielectric fitting.
Plastic pipes are usually black and clamps should be visible.
Benefits of galvanized pipes.
This eventually causes pipe degradation and leakage.
First you will want to coat the dielectric fitting with pipe tape.
Galvanized steel pipes on the other hand are a steel gray color.
Copper is the material most often used by today s home builders and homeowners when installing plumbing.

Whenever you join copper water lines to galvanized steel pipe you should be concerned about the corrosion caused by joining two dissimilar metals called galvanic corrosion an electrochemical reaction occurs that causes the steel pipe in this case to rust and clog up.
Let s see below the best application for the most common used plumbing pipes.
