Will,I agree with the factory about thermal expansion and a closed system, but a T&P valve is still considered a safety relief valve by most and should be treated as such(old school in me). While thermal expansion could be the culprit for a weeping T&P valve, Jacks comment about released pressure caused me to speculate/assume beyond a simple weep or drip ,mainly because of his shortage of hot water.
Your post did get me thinking why Keystone, as well as all mfgs, don't just go ahead and install a thermal expansion device as a necessary part of the hot water system(IBC code on a stick house) and where in the heck is the check valve on the Monty's fresh water system that makes this a closed system.

The city water inlet ordinarily has a check in it. I've wanted to check the pressure on the water system in the RV to see how much it rises due to thermal expansion. I've often wondered if we might be wasting our time with a regulator on the inlet if the "closed" system builds up much pressure. It does seem we get a sudden burst of pressure, especially when we first turn the shower on. We're dealing with a new water heater in this thread, but, I know ours performs a lot better after I flushed it out the other day. At two years, the anode looked like a coat hanger wire.
