You have to open the valve and let the air out first. If you don't it will be full of air.Hi, can anyone offer advice on refilling LPG. Refilling for the 1st time, I understand release valve should be open whilst filling, but should it be hissing and smell gas, not sure if this is safe!! Also does full on the gauge indicate 80% full. Cheers
You always should open the bleeder valve and let the air out before filling. We have been told this by the propane people who have been schooled how to fill these tanks. Some states require a license to fill them.Air shouldn't be able to get in, unless you have a leak. The liquid is under pressure so will fill with liquid and expand into gas as you take it off. I have never opened the valve in 8 years.
Our class C back in the 70's did fill all the way up. This is OK in Winter or a cooler climate area, but I think if we had been in Texas then it would have been dangerous.Possibly more of a problem in hotter climates. Like Texas and Florida. A really hot day here is 30c, I don't think the gas ever gets warm enough to cause a problem.
Our summers are in triple digits. Our generator was a propane generator. We had the AC on all night and ran out of propane because of this. The AC in these temps really suck up the propane. If you have an appliance on board that automatically tries to ignite, that brings air in to the tank. We did not know this and did not know that the AC used so much propane. Everyday is a learning curve in this world for us.Air shouldn't be able to get in, unless you have a leak.
