r/propane

I just checked the tank in anticipation of starting up the fireplace for the season and discovered it was empty as I can no longer see the level indicator. I thought it had a slow leak but a previous check by the propane company didn't discover anything obvious. I'm wondering how to proceed as it will be expensive to have the tank replaced as it would have to be dug out by hand as there is no way to bring in equipment any more to my backyard as they have already tried that once. I'm also thinking about retiring the propane fireplace and installing an electric one in its place so I would then have to retire the tank in place in a safe manner if allowed. Any suggestions appreciated.

We built a house about 2 years ago now and have a 120 gal propane tank. It’s directly outside of the house not even a foot away from the siding and the line runs to our fireplace insert on the complete opposite side of the house. A house blew up the other day in the same county we live in and it’s rumored that the homeowner just had propane delivered the day before the explosion. With that being said, I’m definitely paranoid. Should the tank be farther away from our house? Is having a line run to the opposite end of the house a bad set up? Anything else I should be checking regularly to make sure it’s safe?

I’m doing a startup on a new propane furnace install and I’m getting a major inlet pressure drop when the furnace fires.

The LP conversion kit for the furnace calls for around 11” WC manifold pressure on high fire and 5” WC on low fire.

What I’m seeing:
Propane tank was recently filled.
Brand-new two-stage regulator installed at the tank.
About 75–100 ft total run from the tank to the furnace.
Gas line is 3/4” galvanized pipe.
Roughly 50 ft of the line is underground from the tank toward the house.
Static pressure at the furnace looks normal.
As soon as the furnace fires, inlet pressure at the furnace drops to about 3.5” WC.
The low gas pressure switch then opens and shuts the gas valve off.
If I check pressure directly at the outlet of the propane regulator while the furnace is firing, it only drops to around 11” WC.
So it seems like I have roughly 11” WC leaving the regulator under load, but only about 3.5” WC reaching the furnace.
I’m not a propane expert, but 3/4” pipe seems like it should be large enough for a roughly 60k BTU furnace over this distance.

Does this sound like a restriction somewhere in the underground/house gas piping rather than a regulator sizing issue? Could a partially blocked pipe, valve, fitting, debris, or damaged underground section cause this much pressure drop?
What would you guys check next?

Thinking of applying to be a bobtail bulk driver at Suburban propane. Know a couple guys there already and they say the pay and schedule is good. Any advice on Suburban or what to expect?

I'm in South Florida, the Fort Lauderdale area. I have an aboveground 120 gallon tank that I need to have removed. How can I find a contractor to do this?
