I have a roughly 10 year old GE hot water heater. The hot water flow is noticeably lower than the cold water flow. When we bought the house, I didn't like it, so I had the pressure regulator replaced and had the city test the street pressure. They said it was in spec, but wouldn't give me a number. After the regulator, my water pressure is about 60 PSI, which I think is about right (Y/N ?). Neighbors have no similar issues. Can I get a plumber to test and debug my hot water lines? Is it most likely the fill tube on the current heater and I may as well replace the whole thing? I like to know why things are wrong and replacing a hot water heater only to find out that I still have low hot pressure would be a painful learning experience. I'm guessing $700 to $1,000 painful.
