As someone stated, lighting this unknown vapor inside your trailer is not a good thing.
I always pull the pressure relief valve on the tank to fill it and then I know for sure it is full before turning it on.
Never heard of this before but sure is interesting.
This is incorrect, never open the T&P valve to fill, doing so will eliminate the air pocket that you want. The water pump will short cycle if no there is no air and the valve may drip as there is no room for expansion.
Works for me for the last 17 years. Never use the water pump anyway. Would rather do it my way than have gas blowing through my piping.
