With cold weather coming it is a good time to get your LP/propane system looked at by a pro so you will have heat and cooking fuel when needed.

Sticky LP problem: Valve not passing gas

by Rick Weston
Here’s a nightmare: It’s a cold day, your rig is freezing and you’re out of LP. So you refill your gas cylinders, hook them back up, and try lighting the furnace — with no success. It’s like you never refilled those cursed LP tanks. What’s the matter?
Gas valves on LP bottles can stick “shut” after refilling, even if the valve handle is opened to full. There are a couple of reasons, and usually it’s a simple fix.
Here’s how to figure out if your tank is acting out of sorts and not passing gas as it should. Assuming that your propane regulator is equipped for two cylinders and automatically switches over to another cylinder when one goes empty, it’s easy to tell if your cylinder isn’t opening as it should.
Leave the regulator lever pointed to the cylinder that still has LP in it and connect your “fresh” cylinder up. Now switch the lever over to the filled cylinder but leave the valve closed. The indicator flag on the regulator should show that cylinder as “empty.” If it stays flagged as “OK,” then light a burner on your stove to draw gas from the cylinders. Now the flag should indicate an “empty” for your recently refilled cylinder.
Slowly open the valve just a tiny bit. Now the indicator flag should show “OK.” Proceed to open the cylinder valve completely. If the flag doesn’t show “OK” when you gently open the valve, most likely the overfill protection device (OPD) safety valve is stuck closed.
To resolve the stuck valve, disconnect the cylinder from your regulator and firmly smack the bottom of the cylinder on the ground, jarring it. There’s no need to be gentle about it — smack it hard. This will generally loosen the stuck OPD valve. Now repeat the hookup process as outlined above. This time the flag on the regulator should indicate “OK.” Open the valve fully, and be sure to switch the regulator lever back to the other cylinder.
Rapidly opening the valve on a fresh cylinder often results in a stuck valve situation and can be prevented by the “slow and gentle” method of cracking the gas valve. If your regulator flag still shows your full cylinder as empty, repeat the “LP Cylinder Smack Down” routine again. If it still fails to respond, you’ll need to lug it back to the LP dealer for help.

About smokeycamping

Well let's see have lived in NY for my whole life, have always loved the outdoors (as long as it is warm out) have always hated the cold, and like a dummy have stayed in NY. But now with my second try my wife, we have been camping now for well over 25 yrs. We currently own a 2010 Cedar creek silverback 35TS and can not wait to get out on the highways and see this great country we all call home. Hope to see every National park before my medical issue becomes too bad to travel. I love my African gray parrot (she is my baby) and have two dogs at the time brother and sister mutts, but love them all the same. Have always been a big Nascar fan, love computers (have a number of certificates to build and work on them) am trying to learn photography, enjoy light hiking, being with good friends and folks. country music, pop music and just being outdoors. So I hope someday to meet some of the great people who like what I like and post out there in some great campground somewhere in the country, till then I will keep posting and I hope you keep liking.
