G'day,

Should we add a step to the GMC Fire Guide on the Eastern States Website to pressure test the relief valves on the LPG tank in our
GMC's?

They are all over 30 years old!

If the consensus is yes we need to figger out how to do it safely; would it be safe to pressurize it installed in the tank or not?

If it is OK to leave it installed is it OK to use compressed air.

IIRC if you open the propane tank is allowed to fill with air it must be purged with propane or evacuated and backfilled with
propane to get all the air out.

Regards,
Rob M.
