Hi my name is Gary, I will do my best to help solve your problem
Are you on city water?
Hi there are
Most likely cause is there was a water main break or repair up stream of you and it will clear up in less then 24 hours
or they are flushing the water hydrants which will cause the same thing
and that to will clear up
None of my neighbors are having this problem and it is only the hot water
Is it rusty looking or more like black sludge and or black pieces
and does it smell
have you had any work done lately on your water system?
what type of water piping do you have? Galvanized steel(grey metal) copper, or plastic?
I'm not sure...I know it is not copper
Its probably galvanized steel which is the only material that would cause this
Its only on the hot water
If you have galvanized steel this piping it corrodes, and you are probably seeing some of this in the water, the only solution is to replace the piping, with a more up to date material such as copper or plastic
This is one of the reasons we do not use this material anymore
how old is your house?
12 years old
I would think if it is the pipes it would be dirty in hot and cold
Then you have copper or plastic cpvc, or pex. Your house is to new to have galvanized steel and thats not the problem
When you say dirty? fill a glass of water and what color is it and see if you can see any type of material or debris in the water and describe it
It seems you are offline let me know the result and we can go from there Thanks Gary
