I wonder if it might help to drain the water heater completely, then refill it. That way, the air pocket on top will get rebuilt, which should minimize the amount of water coming from the relief valve.
Very short answer: YES.
Somewhat longer answer: That is, in fact, the recommended first thing to try.
Let Water cool, turn off city water and open a faucet to bleed off pressure, Remove drain plug, If WH is a Surburan inspect anode (if so equipped) if Atwood, now is a good time to do a drain mod (Mods posted in other threads).
Open TPR valve using manual lever, Let drain, Use flush wand to flush out any debris in tank,, Close TPR,, Replace anode or plug (Depending on heater model) Re-charge water system.
Restore heat
Job done.
