Bad Acme Nut Pigtails

I guess there's a check valve in these thst get stuck. I've had 2 of them go bad on me now out 9 the blue over 7 years. Last night, one of my tanks ran out and they did not swap to the other tank... and it got a bit chilly for May in Georgia (low 40s ).

I though the switch over valve was bad, but went through the process of elimination and found a pig tail was not letting gas through. I picked up another at CW and all is well. 2nd time this has happend.

Is there anything that causes this or can do to stop it from happening? Can the pigtails be fixed when this happens?

Unfortunitaly no they are not repairable. You could go back to the POL style pigtails but there are issues with those (tools to change tank)

I have my undocumented opinion why they stick.
I had one seem to go bad but the cause was that I opened my propane bottle too fast and forced fluid or gas into the line which jammed or stuck the valve closed.

I would shut off the tank and disconnect the line and see if tapping it would open it back up. Then reinstall and slowly open the tank valve and see if that works.
Can't help in trying it or even tapping the line after disconnected with a handle of a screw driver to see if that help dislodge it from closed..
Good luck

These pigtails are actually a "hose within a hose" so to speak. Brake lines on auto's are built the same way. The inner hose is made to withstand the gas, or brake fluid, and the outer hose is made to withstand the pressure(s) the inner hose deals with. That said--the inner hose of these pigtails will collapse at some opportune time making them useless. My local propane dealer has a display on the counter that he made to show a collapsed inner hose. My dealer also has told me not to open the gas valve on the bottle fast/suddenly. Just crack it open until the system is full then open it as Iggy stated.

My 2014 2318G was setting off the CO/Propane alarm when using the heater. Found a gas leak where the pigtail connects to the regulator. Fixed that, and the heater worked w/ no alarm, but left tank started making a "pinging" sound, as if being tapped with a small hammer. I placed my fingers on the pigtail and could feel a very sharp vibration in sync with the pinging sound. I replaced the pigtail and all is working properly now.
