Depends on the water quality and what type of galvanized piping was used
The drain metal pipes are usually coated and galvanized because of the hard water.
galvanized iron pipes commonly used on water pipe lines, it is dipped into zinc for corrosion protection
May indicate rust from galvanized pipe feed lines or dirt in water supply.
If galvanized piping was uset to plum the house, it may have rusted shut, an easy fix would be to run a new line in copper or PEX from the water heater to the valve
galvanized water lines, cast iron drain lines, sometimes lead pipes, terracotta or clay pipes, and in rare cases wooden pipes.
yes old galv pipe will flake and the iron will start to rust causing rusty water.
Yes it can be used but is not corrosive resistance
if the water in the pipes freezes, it will expand and break the pipes.
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
You have old rust clogged galvanized pipes and someone cut the water on in another outlet. Fixit1
