Also be aware that directly joining two different types of metals in this case galvanized steel pipe and copper can cause rapid corrosion at the joint called dielectric corrosion.
Galvanized pipe to copper pipe connection.
The rubber or plastic.
Eventually galvanized pipe will have to be replaced and when that happens your choices are to replace it with more galvanized pipe copper pipe or plastic pipe.
It is possible to connect a copper pipe fitting to a galvanized steel pipe.
When water runs through pipes that are made of two different metals it creates an electrical charge that can cause corrosion and leaks in the pipe.
The easiest way to connect the copper and galvanized pipes is to use your wrench and unscrew the galvanized piece from the connecting threads.
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.
The reaction creates scale which will eventually clog the pipe.
This will keep the.
When connecting a copper pipe fitting to a galvanized steel pipe you must use a dielectric fitting.
The problem with galvanized pipe is that it reacts with the minerals in the water supply.
How to connect copper to galvanized plumbing.
Sweat on the copper part of the dielectric fitting which is threaded coat all the threads with tape or pipe compound and.
Next connect copper pipes together until you reach the galvanized pipe threads.
