Water heater overflow running
The pressure release valve on my water heater runs almost constantly. The only time it isn't open is if I am using the hot water, and for a few minutes afterwards. The tank is only a year and a half old, as is the expansion tank. Ive turned the temperature, and checked my water pressure (it's somewhere between 60 and 70psi) and the new valve said it was rated for up to 150psi and 200 degrees. Not sure what else I can do to stop this from happening.
Please help!!

You said "new valve"... does that mean you have already tried replacing the valve? You said you checked the water pressure turned down the thermostat but have you checked the water temp? Actually check the water's temp or have you noticed that the hot water is scalding hot?

Yes, I replaced the valve once already. I haven't checked the temperature of the water itself, but I wouldn't say it scalding. Especially after turning it down, it's barely hot. Not I'd say very warm.

The expansion tank may have lost its air cushion, perhaps someone let the air out as a prank, or the pressure tank was not pressurized adequately to begin with.
TUrn off the water, open a hot faucet upstairs, and set the expansion tank to slightly less than the normal water system pressure.
