Why Is My Toilet Water Brown? 6 Causes
Brown water in the toilet can indicate a plumbing problem that requires serious attention, or it may just be a minor nuisance. Here are 6 reasons why the water in your toilet may appear discoloured.
● Rusty Pipes
Rusty pipes are one of the main reasons why toilet water turns brown. This happens when the inside of the pipes becomes corroded, giving the water a brown or reddish tint.

● Municipal Water Supply Issues
Sometimes, the brown water problem is not with your home’s plumbing but with the water supply from the city. Rusty water mains or maintenance work can cause water discolouration. Contact your water provider to know if there are any known problems with the water supply.
● Sediment Buildup
Sediment accumulation in your toilet tank can cause brown water, which is common if you have hard water containing high mineral levels.
