lower your thermostats a bit. If your temperature is set to the hottest setting, then chances are no relief valve will do

I believe the problem you had with the pop off valve is a one time thing since you said you just installed the water h eater
The pop off valve is a pressure relief valve that is activated by build up in the tank from excessive pressure either through too much heat or pressure which works by pressing aginst a spring loaded valve
If you go to the whater heater and look at the valve ther is a handle on it take your hand (stand clear of valve opening) and slowly pull it you will see water start to come out
More than likely a new valve could have had a piece of debris in it or was partially open
re
If the heater was overheating the valve would stay open and you would see extremly hot water rushing out
I do not recommend that you replace the valve unless it continues
Good luck to you

It could be back flowing into the hot water heater tank which is not full because of the leak. Even though the valve is closed on the cold water entry side, there is probably no valve on the exit side. That is how it is returning to the tank.

what is the water pressure on the cold side? You may need to install a pressure reducing valve at the water heater inlet to reduce inlet pressure and keep pop off valve from opening when not needed.

Double check that washers inside fittings attached to back of tank, are not wedged or pinched in there restricting flow. Drain tank, relieve water pressure prior, obviously. The other thing is to check that the by-pass is allowing good flow in to tank when in normal operation mode. Have seen those only go half way inside valve, but lever is at wide open setting. If all that checks out, try removing the check valve on tank, and replace it with a 1/2" galvanized pipe nipple, ( or certified plastic/nylon fitting same size) and reconnect water line direct to that, without a check valve. That should do it if nothing else was wrong. Now you have a choice, either change it or leave it out if everything seems ok, but double check that hot water isn't siphoning back to another utility such as toilet if you leave it out and toilet is close. Feeling that cold line (inlet) when water is hot should tell you. I've seen the check valve in both locations, hot (at top of tank) and cold (at bottom of tank -inlet) Not 100% sure why, right from factory that way, but I say, put it on bottom fitting if required at all. Let me know how you make out.
Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.
Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately
Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.
Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.
Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.
Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.
