I recently bought my first home, and the first thing we noticed is that the dynamic hot water pressure is pretty low compared to the cold water pressure. I purchased a water pressure gauge and found that the static hot water pressure is identical to the cold water static water pressure (about 95 PSI). When I turn on a cold tap, the dynamic cold water pressure reads at about 85 PSI, which is totally cool. When I do the same for the hot water, it drops waaay waaay lower.
When I attached a hose to my water heater to try to flush it, the water pressure was amazing, and the water was perfectly clear. So it doesnt appear to have a sediment problem.
Basically this results in a low hot water flow rate for the entire house. The water heater (probably near the end of life) is a 40 gallon gas heater. Any idea what might be causing this? Anyway I can try to fix this with out having to buy a new water heater or call a plumber?
