Go to the hardware store and buy a water pressure gauge. Then go to Tanklets using the link at the top of the topics index. Click on Temperature/Pressure Relief Valve Issus.
Test static pressure to make sure it’s 80 psi or less. If it’s more, you need a pressure reducer. Then do the test for thermal expansion. If you have spikes over 80, you need an expansion tank.
It is entirely possible that the reason your previous tank didn’t have this problem is because the T&P was clogged shut.
