Hot water pipe rust first as compared to the cold water pipe for the same chemical composition of the water.
Rust popped off inside the pipe and plugged the faucet.
warm water will rust metal faster
Copper can rust
Iron will slowly rust in cold water.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
the heat from hot water will heat the pipe, loosening the bonds between the molecules in the pipe and allowing for more oxygen molecules to enter, creating more rust much faster. cold water will do the opposite; it will make the bonds tighter and allow LESS oxygen in.
mold or rust
It will rust fairly quickly causing brown water and over time will rust through and leak.
Salty water will rust metal the fastest because the presence of salt increases the rate of oxidation, which leads to rust formation. Cold water alone does not promote rusting, but when combined with salt, the process is accelerated.
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
Depending on how old Ur heater is and what type of plumbing u got normality rust a reddish color comes from Ur heater u also get it from old iron pipe
