Yellow or rust-colored hot water usually means sediment or rust in the water heater, and it often clears after running. A flush is the first step, and the heater's age decides the rest.
The cause
Sediment and rust at the bottom of the tank color the hot water yellow or orange, especially after the heater has sat. freezing winters and hard water are both common, and older homes often have aging supply lines In Northglenn, older tanks and hard water are the usual cause.
The test
Run the hot water for a few minutes — if it clears, it was a buildup at the tank; if it stays colored, the tank is rusting.
The flush
Flushing the tank removes the sediment, and an annual flush prevents the color from returning.
The tank
Persistent yellow water from an old, rusting tank means replacement, because the tank lining is failing.
The call
Clear the yellow and protect the heater. Call 888-217-3585 and Northglenn Plumber Connect will match you with a Northglenn pro.
