Betcha that there is a O-ring under than 4 bolt flange in a machined groove. Flange is probably a 2-1/32 or 2 bolt circle, same as Rochester junior and senior gauges. Just a wild guess on my part.

This article should explain what purging is and why it is important. It's a bit long winded, but it explains everything.

For some, this shorter version will do:

The key is that purging is done with LP vapor, not the normal liquid fill set-up. Some retail LP outlets will not, or cannot, perform purging.
this is interesting but I have never seen Menards or a Tractor supply store that sells new tanks and fills them at the store perform this procedure, I doubt these kids have been trained or even heard of such a thing.

I'm wondering if by me running the LP tank completely empty ,did I cause the failure of the OPV ?

No... I've run RV tanks dry many times over the years with no difficulties. The OPD is just a float operated valve. When the tank runs dry the only thing that happens to it is the float doesn't float...  ;)

No, I run my add-on tanks dry all the time...usually at 3am.

well, I was completely wrong about these two stores not purging their new tanks, I called both of them and they both do. Only new tanks and, Menards does fill Motorhomes here in Morris, Illinois.
