You need to make sure the tank is never overfilled. When filling, the van
needs to level, the bleeder open and the fill has to stop as soon as any
liquid exists the bleeder. This level will allow for expansion. Another
issue with an overfilled tank is the possibility of liquid exiting the
delivery valve. This is one reason RV are required to have a 2 stage
regulator. The combination of the 2 stages will allow the liquid to expand
and reduce the risk of liquid entering the stove. However, liquid will
carry the mercapton, (odorant). This will leave a gummy reside in the
plumbing and if done often enough will carry into he fridge and stove and
make a real mess.

Subject: propane rebuild and safety

I just fitted my old propane tank with new valves and new regulator.  I'm
ready to hang it back on the van, but I'm a little concerned about safety.
The fill valve is manual in place of the old auto stop valve.  Is this a
safe way to go?  Can this newly valved tank handle expansion of the
propane?  Did the old fill valve and or regulator have some kind of relief
valve for increased pressure?  I read an archived post that seemed to
suggest that this config. could not handle expansion and posed a safety
risk.

Thanks again for you insights!
