        The drip is from my pressure relief valve. I replaced it today (new and old one rated as 150 psi) and the new one drips also.
        Possible related facts:
        My house water pressure is 60psi. Also, when I moved in 4 years ago, I had problems with hot water coming out of some of the cold water faucets (those close to the heater) so I installed a device (name escapes me) that prevents hot water from back flowing into the cold water inlet. This fixed that problem.

        What do i do? Can I try a slighly higer rated pressure relief valve or is that dangerous? What other options do I have?

          Do not change to a higher T&P valve. Your system needs to have a thermal expansion tank installed. This compensates for the increased pressure from the heating water.

            Remove the damn NO NAME DEVICE before you rupture your tank.

            You should invest some time reading the ASME section IV code before you blow yourself away
