Using big bottles

I have 2 100# lp bottles I want to put in the back of my truck. Can you fill and use them laying on their side? Or do they need to be upright?

Unless they are bottles made for laying down, normal 100 lb. bottles will not work correctly except standing upright.

IF they are intended to sit upright, then they must be filled, used and stored UPRIGHT. Otherwise they simply do not work properly and what's worse are dangerous

One of the safety devies (you can see this) is an excess pressure relief valve. it is part of the valve assembley. If the pressure in the tank goes too high it vents GAS, not liquid, propane.

lay it on it's side nad it will vent LIQUID propane.

Way way way more dangerous.

They absolutely need to be used upright. If liquid propane gets into the regulator it can cause serious problems.

As an aside, a certified propane tech told me how to do an emergency fill on my built in tank by inverting a 100# on a truck bed and running a hose to the fill adapter on the MH tank. The gas pressure in the 100 will pump the liquid until the pressures come close to equalizing. He emphasized that this is an emergency procedure only and should not be used regularly.

Many times I have taken them up to get filled and layed them down in my truck (filled) until I got them home. Are you saying that this practice is dangerous?

With the bottle laying horizontal and near full, the over pressure valve is covered with liquid propane. It is designed to relieve vapor state propane. So transporting on the side can be dangerous....

The Oregon State Police say yes. I agree.

No true. The Oregon State Police document referenced above describes the OPD as follows:

HOW THE OPD WORKS

During the refilling process the valve automatically closes when the DOT Cylinder has received the correct volume of propane (filling to approximently 80% of the maximum capacity of the cylinder).

The OPD is not a safety valve which will be opened by excessive pressure. I don't believe there is a problem with transporting cylinders on their side, just a problem with using them on their side due to potential damage to the regulator.

The OPd on a tank also has a thermal release. I do not think much of lawyers that try to write laws that over-ride good engineering practice.

According to Propane 101 , 100# cylinders are exempt from OPD rules.

I have 2 100# that i use at home and used to fill them at the local tru Value because it was the cheapest place around. Went one day to pick them up and the guy had a fit and wouldn't let me take them because they would be laid down. Had to go back the next day to get them. i never went back after that. I usually put them in the back of the Grand Cheorkee no ropblem to go the mile

I have ran into the problem of filler not allowing me to lay them down-mine are in the back of the truck so transport them out of site and then lay them down.Mine do not have the port like the 20/30 lb bottles have,just got it recertified.
