Help!
I've just got home to find my hot water is brown. It looks too murky to have a bath in, and if I leave it it eventually settles to a fine dust at the bottom.
The cold water is fine, even after heating in the kettle, so it doesn't seem to be a contaminant in the water supply.
The hot water system is thermal store system, less than 4 years old. It's a big vented cylinder with separate boiler and hot water coils. The hot water coil is at mains pressure, so it can't be the cylinder leaking into the tap water - if the coil had failed it would be going the other way and coming out the overflow.
What could it be? The only thing I can think of is the pipes disintegrating from the inside, is that possible?
