Where is the whooshing coming from? If the tank was leaking it would leak all the time.


The leak is from the valve stem when open, not when closed.

The gas company I just took it to said they could not work on it as it is mounted under the side of my RV. It is no longer leaking and I am running the furnace now to drain some propane and the LiFePo4 batteries before winter storage. I do wish I could find someone to replace the stem or the whole tank. I've made a lot of calls to Rv places and gas places to no avail.

I am surprised that there is no one around to do repairs, especially in a major industrial area like yours. Very strange.

Are they saying that if you take out the tank and bring it in, they will work on it?

I do not think the tank can be 'taken out'. It is permanently mounted under the side of the van. The rv would probably need to be put up on a lift (it is already 9' high). I cannot see how it is attached from underneath.

ASME tank has welded on brackets on top and is bolted in place.

The tank is attached with bolts to a bracket. But, those 6.5 gallon tanks are small and crammed into an even smaller space. So, they may have bolted the tank to the bracket, welded the bracket to the frame and build everything over the tank denying access to the bolts. The typical upgraded replacement is a Manchester 6811 or 6813 tank but you'll have to remove the one you have now. The new ones have side brackets unlike some of the older ones with brackets near the top (easy to build over). You'll do better having an RV tech just replace the valve.

Update:
2 days ago I opened the valve and it was leaking a little. I closed it and opened it to the same result. Yesterday I opened it and left it open thinking that may empty the tank. I went out later and it was not leaking. It didn't leak anytime I checked it even after leaving it open all night. The temp got down to 10 last night. Today I opened it and closed it a few times. No leaking noise. After a few minutes I did notice a slight smell. It seemed to be not leaking when all the way closed or open.
I scraped off some of the flaking paint to show some of the bad rust. I'll try to attach pics. I wish I could get the tank replaced, but no RV or propane business near me will touch it.

For your own safety, and everyone around you, I would highly recommend voiding the tank by running the furnace and HWT until the tank is empty. Then never fill it again.
That thing is a bomb waiting to go off.

This is an ASTM "TANK", manufactured by Manchester Tank

From "camper van hq"

I don't know where this company is located but they sell them and could probably give you good advice on where to go next.

I may be possible to salvage your tank by removing all the fittings, and sand blasting or glass bead blasting the paint and rust off. You can clean it (inside and out), paint it, and replace all the various fittings. 4 new bolts and nuts, along with washers, and you are back in business.
