If you have good pressure EXCEPT your hot water supply it sounds like someone failed to do basic plumbing properly.
A lot of unknowing folks who think they are qualified plumbers mix various metals without any consideration to codes or proper piping conditions.
What you should do is have a licensed Master Plumber or Gas fitter check the piping to and away from the heater and see if someone forgot to install a dielectric fitting like an insulated nipple or dielectric union.
While they are at it let them pull the relief valve and possibly change it as it sounds like a possible corrosion problem do to improper installation
Have a great one
