Why shouldn’t you connect galvanized pipe with brass?
- Corrode the pipe: The most important reason you should not connect galvanized pipe with brass is corrosion. You might know that two dissimilar metals will go through galvanic corrosion if they are close. ...
- Reduce durability: We expect the system to be durable when we install water supply pipelines. ...
- Other problems: Other problems can also occur due to connecting these two dissimilar metals. ...
Does galvanized react with brass?
If an installation requires contact between galvanized materials and copper or brass in a moist or humid environment, rapid corrosion of the zinc may occur. Even runoff water from copper or brass surfaces can contain enough dissolved copper to cause rapid corrosion.
Can you put galvanized and brass fittings together?
It is not even a good idea to have galvanized steel in close proximity to copper or brass; runoff water, especially in locations subject to acid rain, can carry enough copper to erode the zinc coating on galvanized steel.
Can you connect brass and steel pipe?
When it comes to stainless steel (301, 304 and 310) and brass, they are only two metals apart, which means they can be safely connected together with minimal risk of galvanic corrosion.
Can you use copper and galvanized pipe together?
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). To limit this problem, make the steel/copper connections with special dielectric unions rather than with a regular coupling.
What fitting is required for copper with galvanized pipe?
We recommend a transition fitting called a dielectric union. This has a threaded steel female pipe fitting on one end, which is threaded onto the male threads of the galvanized steel pipe. The other end has a female copper hub fitting, which slides over onto the copper tubing.
How do you join copper and galvanized pipe?

After that's screwed into place.
What happens when copper pipe touching galvanized pipe?
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.
Does brass and steel react?
As the series suggests, steel and aluminum are relatively compatible, but if brass and steel contact, the steel will corrode because it is more anodic than the brass.
Is brass better than galvanized?
Brass usually lasts longer since galvanized usually corrodes or rusts apart in 10-20 years. It is usually worth playing a little more for brass.
When did they stop using galvanized pipes in homes?
1960Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines. Today, however, we have learned that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside.
Can I use SharkBite fittings on galvanized pipe?
The SharkBite push to connect fittings are not designed to press on galvanized pipe. SharkBite makes a threaded to press fit transition adapter to fit your PEX to galvanized. If you want to rethread your galvanized pipe, you will need to square cut it.
What is the life expectancy of galvanized pipe?
40 to 50 yearsMany plumbing websites say galvanized pipes have a life expectancy of 40 to 50 years, while others say 80 to 100.

Will brass and stainless steel corrode?
If brass and aluminum plates are connected by a passivated 304 stainless steel bolt, both the brass and the aluminum will corrode severely where they touch the stainless steel because they are much more anodic than stainless steel.
Can I connect PEX to galvanized?
Install a threaded transition fitting to go from galvanized pipe/fitting to PEX tubing. Depending on the type of PEX fittings used, a dielectric union might be needed. Connect the PEX tubing to the fitting using a compatible method. Check connection for accuracy.
Can you connect galvanized pipe to stainless steel?
Galvanized steel can be paired with many other metals. Specialized construction and fabrication needs may put galvanized steel in contact with stainless steel, aluminum, copper, and other weathering steel. The juxtaposition of galvanized steel with other metals can result in a condition called galvanic corrosion.
