1000g propane tank floated out of the ground.

We have a homeowner's association and there is a rule that tanks must be buried or screened. We have been delinquent in getting this done, so I was pretty pleased to not only have a big tank, but to have it out of sight. Thanks much for the links on the bouyancy and the anchors. I think I'm going to do a combination of sloping the earth better around the tank, perforated drain pipe as deep as I can get it, and earth anchors. Pouring concrete would certainly work, but I would like to have the excavator here for a single day. Lift the tank, excavate, drop, anchor, re-bury. We were definitely lucky that the line didn't break. There wasn't any slack on the line when we buried it the first time and that is the reason it rotated as it rose.

With 4,000 lbs of buoyancy (empty tank--assuming the previous commenter's math is right), eight anchors would be holding just 500 lbs each.

I guess it wasn't. The link says a 1000 gallon tank has a buoyancy of 9110 pounds.

Personally, I'd never bury it and I'd be going the screened route instead......Mike

I agree also.
A few 4x4 posts and some of that plastic lattice work in white or brown, a couple attractive shrubs and some annual flowers and you're good to go.

Looking at all that water in that hole, I'd never put it back in there again. Water table's too high.
Lucky it wasn't somebody's granny in coffin! :laughing:

I guess the HOA will not let you paint it like a pig, watermelon etc. I love seeing those. You could make a real easy screen by putting in t-posts and zip tieing the plastic lattice over them. Just watch you dont hit the copper line.

Service station tanks have the same problem. We ballast them with concrete on top of them. 1000 gallons is only 4 tons. Concrete weighs 3600 lbs per cubic yard, so 3 yards would do it. Bury the tank, add sand to isolate the metal from the concrete, tie in enough rebar to keep the concrete from falling apart, and pour.

Aesthetics. You don't have to look at it in your yard. Propane tanks, even when dressed up with lattice or screening plants, are still not the prettiest thing in the yard...

My thoughts exactly, what is the point?

Was this installation done to code? Inspected? Did a contractor do the installation?

Those don't always catch all issues, but should give you some recourse if it was a contracted installation.
