Why is My Hot Water Black?

Published in Water Discoloration 1 min read

If your hot water is black, one potential cause, according to available information, is rusty pipes.

Potential Cause: Rusty Pipes

Discolored water, specifically appearing black, can be a sign of issues within your plumbing system. Based on the provided reference, rusty pipes can contribute to this problem.

Several types of pipes are susceptible to rust, including:

  • Steel pipes
  • Iron pipes
  • Copper pipes
  • Pipes galvanized with a protective zinc layer

When these pipes corrode internally, the rust can break off and mix with the water flowing through them. If rusty pipes are the cause of your black water, you may also notice hard, misshapen particles present in the discolored water coming from your faucets.

This indicates that the black color is likely due to accumulated rust and sediment from the pipes.

If you observe black water with these characteristics, it's advisable to consult a plumbing professional to inspect your pipes and determine the source of the discoloration.
