Question DetailsAsked on 3/6/2016

Brown water from my hot water

I have a boiler and hot water tank. Both are 6 years old. Recently the hot water has been coming out brown/orange with grains in it. It comes from all faucets. I have a whole house filter and the cold is clean. What is the issue? Thanks.

Here are links to several similar questions with answers -

First step would be to drain off about 5 gallons of water from the bottom of the tank to see if it is due to sediment in the bottom of the tank. If keeps coming out dirty to the end of the 5 gallons without clearing up pretty quickly, drain out 50 gallons or so with a hose running through a bucket to see if it keeps coming dirty. If no, then might be OK after shutting the drain off. If you are getting chunks and flakes in the water it probably means heavy scale or iron bacterial buildup is forming in your water pipes, or that the lining of the tank is shot and about to fail. Would have to shut off water and disconnect a couple of pipes to check that out - if interior of pipes are all built up, is iron or manganese buildup or corrosion of the pipes. If pipes look good, would need a fiber optic scope to look into the tank to see if it is corroding, and to see if the corrosion protective anode has eroded away.

Obviously, if not a DIY person, Plumbing is the Search the List category for a tech to check this out.

Oh - you said only hot water is discolored - so incoming water, pump pressure tank, or well could not be the source of the problem, nor could the incoming water from the source (public water or well).
