I have a problem with my hot water side low pressure on the hot side cold side is working fine. The house is only 5 years old everything new built 5 years ago. The pressure is gone on the hot side but the cold pressure is working fine. How can I tell if its not the main from the street since we had an ice storm last night. Tips and help please.

Not the main because if it were the main both hot and cold would be the same. Are you having an issue with all fixtures or just one? If all we will be looking at the water heater so be propared to tell us what you have.
