Turning off propane question

[CSroo]

Have noticed that when I turn off the propane at the tank it doesn’t completely close. I can turn the stove on and low flame will continue to run indefinitely.

What’s the easiest fix for this? I hand tightened it is much as I could but figured using a wrench would be a bad idea.

It may take awhile to purge all the gas from the lines running from the onboard tank....enough to keep a small flame running for a bit.

Does yours run longer than 5-10 minutes?

The stove can in fact burn for a long time with the residual gas left in the line but, if you do have a leaking valve on the tank have it checked out and replaced asap.
Two things in an rv where I don't cut corners, electric and propane.

Thanks. Ran it for a good 10 but will try again today to ensure no leak

Appreciate it

Are both tanks turned off?

I would make a dish soap and water mixture, remove the hose fitting from the tank on both tanks and drizzle some soap mixture into the valves. If you got bubbles, you have a leak.

Try turning the valve a bit more and see if it stops. If so, then close them harder. If not, use the propane up and have the tank replaced or have the valve replaced based on cost.

You can not build up a dangerous situation with a leaking tank in the open air.

I think there is a check valve in the tank valve that should cut the gas off.
You can remove the hose with the valve on and no gas would flow as the check valve shuts it off therefore you can not tell if the valve is faulty or not. You would have to disconnect the hose downstream from the tank to check this out.

If you do suspect a leaky tank shutoff valve, by all means leave that tank disconnected until you can get it taken care of. Cypressloser is absolutely correct, there's zero tolerance for propane problems.

People....

This is posted under the forum heading of FR3 motorhomes. There is only one propane tank attached to the chassis on motorhomes....unles CSroo posted under the wrong heading.

Propane cylinders can be the disposable green ones for Coleman burners, and even the cylinders found in Travel Trailers and 5th Wheels.

If the valve is leaking through why would he leave the tank disconnected? Doing so allows propane to vent to the atmosphere. Not a good thing.

Shoot, I usually check that too! You mean not everyone has a rig just like mine?

I have a 2015 GT which had a faulty shutoff valve last year. CAUTION, if you disconnect the line you will allow propane to shoot out of the failed tank valve and you'll be unable to stop the flow! Unfortunately, I took it to the dealer to fix. That turned into a nightmare. They took several days to burn off the propane with a vent stand. (Said it was an EPA requirement.) Then they replaced the valve and refilled the tank. The dealer said it took 10 hours but the service contract company said it should have only taken 5 hours. Guess who paid the difference ($300). Lesson learned. Burn off the excess propane by running the furnace(s) then change the valve yourself. Valve is only about $35! Once installed, have the tank purged and refilled. This way, it would have all cost me less than $200, which would have been less than the difference the warranty company wouldn't pay the dealer.

Vince and Charlette,

So... the dealer charged you an hourly rate while a flame burned off the propane? I googled "Releasing propane into the air" and one of the resulting pages stated:

"Propane is non-toxic, non-caustic and will not create an environmental hazard if released as a liquid or vapor into water or soil. If spilled in large quantity, the only environmental damage that may occur is freezing any organism or plant life in the immediate area."

I'd suggest checking with a local propane supplier to see if there's really any EPA requirements.
