Galvanized Piping
Galvanizing is the application of
molten zinc to pre-formed steel pipe. Zinc gives iron a limited, cathodic protection.
Note: Common impurities in
zinc are lead and cadmium.
Modes of failure
Four basic processes, indirectly related,
stimulate interest in corrosion of galvanized pipe.
- General, uniform corrosion
- Release of metals
- Pitting
- Tuberculation
Note: How fast corrosion happens will vary
due to water quality and manufacturing
processes of galvanized pipe.
Symptoms of corrosion
(Noticeable at tap)
- Low volume/pressure
- High level of iron and zinc
- Metallic taste
- Mineral Build up
- Discoloration of water
Other Materials
There are other, often inexpensive, alternatives to copper piping. All are synthetic.

Copper Piping
- Non corrosive
- Non synthetic (copper piping, with proper installation, will not break down)
- Long, consistent history of reliability
- Solder joints are as strong as pipe
- Can outlast the structure in which it is installed
- Carries a 50 yr. manufactures warranty
- Has stood the test of time to earn customer satisfaction
- Copper is 100% recyclable
- Copper is a sustainable material
- Copper, recovered as scrap, is as usable as primary copper refined from ore.
