What's stuck? It won't take propane or it leaks it out?

As long as you have it removed, just buy a new one. They are not that expensive. I paid $26.00 in 2008. Get it at a propane supply store. Be sure to use thread sealant approved for propane.

the fill neck actually has 2 valves in it. there is the big ball that you can see from the outside and there is an inner check valve also. if the ball is loose then it's probably the inner valve that is stuck. if the tank is empty you can remove the fill neck and see what is wrong.
been there, got the tee shirt.

Thank you all for your input. I took the fill valve apart as much as I could and shot everything w/penetrating oil. The inner valve that pops open when gas flows in seemed to be a little hesitant to open. I worked with it for awhile. I held it to my mouth and blew into it and the valve popped open with very little pressure(wife says I am windy but most of it is low pressure)I would guess maybe 1/2 pound pressure is all the pressure needed. Will try again to fill tomorrow. Thanks for the tip on sealing tape. I used regular teflon tape, hope that is suitable for propane contact.

There os a teflon tape for gas connections. It usually is yellow colored. The white stuff is for water.

inlet valve for the propane ices up when being filled and "hisses" away when
the supply hose is removed. I leave a 5/16" x 12" wood dowel in the propane
compartment to poke at the valve to blow that little bit of ice out and let
it seal. I always warn the propane attendant about this and none of them has
been concerned, so far.

You cannot expect regular white teflon tape to maintain a seal against leaking propane. Change it. It will eventually leak. As Emery said theres a yellow version of the tape specificaly for use with propane.

I was unable to get the old valve working. I Found a new valve in Heath Ohio. They refer to them as 80/20 valves. I had to check a half dozen places to find one in stock. Price has gone up too. It was $90+. It is not the same dimensions as the old valve. There is a shutoff float attached to it........had to remove float to install...no big deal. I always used the purge valve as an indicator when the tank was full. I don't use much propane but it is nice to have sometimes.
Thanks everyone for your suggestions..and....oh yeah...it came with some pipe thread compound on it...blue stuff.

Sorry to have to tell you this but you didn't need an 80/20 valve. This is also called an OPD valve. ( Overfill Prevention Device).Your tank is already set up to give 20% free space above the liquid propane. You should have been able to buy the correct valve for quite a lot less money. I checked on the Internet and the first place I looked had them for $29.83. I probably could have found them for less. If I recall one should be able to buy it for about $20.

I think that the 1-3/4" Acme thread is an outer thread. Usually this fitting has both inner and outer threads.

isn't the Acme thread the one that the hose attaches to? my tank had a reducer bushing to accept the 3/4" pipe thread. i do recall that it had that red sealer on the threads but i added the pipe dope.

Yes, it is. I had assumed that was what Jim Mills meant by an "outie".
Your guess is as good as mine as to what an "inny" and an "outie" is. Actually at first I thought he was referring to his "belly button".
mills
vapor valve appears to be s standard POL type (maybe it has been changed
before?)
mills
I was referring to the propane fill fitting and the propane withdrawal
fitting.
Emery Stora
You are referring to the tank fill valve as an "inny" and the tank
withdrawal valve as the "outie".
The tank fill valve has threads on the inside which fits some fill
lines and it also has threads on the outside so it can be filled by
the larger Acme threaded fill fitting. That is what i thought you
meant by an "inny" and an "outie" which is why I said it had both.
The tank withdrawal is a standard POL valve.

OK, you got me now. what is a POL valve mean?

The sites I have been surfing looking for a new vapor out valve for my
ASME (frame mounted) tank list two types of valves - POL (old type
valve) and the new type OPD (overfill protection device) currently used
for BBQ (DOT) type propane bottles up to but it seems less than 100#
size.
The POL valves use a vent tube, which you open while filling, that
sputters liquid when liquid level reaches the 90% level.
The OPD valves use a float valve to stop the fill process at the 80%
level.
Here is a site with nice pictures

The POL valve got its name from the company that created it.

The new valve would not take propane either :? I just ordered the one that was linked to on this thread.
Very unusual for me to not be able to get gas.......wife says I usually have an abundant supply...but that is another story.
Emery Stora
that would shut off the valve when you reached the 80% point. The
valve must have been ouunted in the closed position.
Emery Stora
Louie Diamond
probably operator error.....at least I didn't cross thread the thing.....will wait on the new one that is on the way...it looks a lot like the old valve....in the meanwhile the ol microwave will get a workout :d
Louie Diamond
Tell ya what.......I must have killed too many brain cells in the 60's.
I still cannot get that tank to take propane.
I bought and installed a new valve(3rd valve now) that fred v suggested. Maybe I should have put a vacuum pump on the tank to pull out all the air before going to the dealer. :?
The tank will take maybe 3/10 gallon and then the fill slow to a crawl.
Their has to be something goin on here that is too basic or too complicated for me to grasp.

What I know about Propane tanks and ASME tanks. Your tank has been opened. Before you try to put in liquid propane, it must/should be purged at leasr 3 times with propane vapour.
2) is the bleed valve open ? If the bleed valve isn't open it wouldn't surprize me if it would not take liquidm and also how would the person filling the tank know when the tank is full ??
WITIK(What I think I know)
DAVE KING(have replaced a fill valve and then the whole tank)
Louie Diamond
yes! Bleed valve is the first thing opened and much air/gas exiting valve was audible.
How can the tank be purged of air if it will not take propane?
Should I leave the purge valve open until pressure is ambient?
The attendant was able to put in about 1 gal after much waiting and conversation.

Re filling a propane tank that has been opened. A "real" propane service facility, eg a place with propane delivery trucks etc, should know about purging a tank. I don't know if a place used to just filling BBQ tanks or vehicles would know.
The place I went to had a BBQ tank with a hose the hooked to the motorhome tank. A BBQ tank is supposed to output only vapour. I don't know how they knew they had enough vapour in the tank to stop filling and then let the vapour out of the motorhome tank. They did this 3 times, and then filled the MH tank with liquid.
O think this is to ensure the MH tank has only propane in it and not air.
If all is well with the MH tank, it is full when liquid comes out the bleed valve on the MH tank. I don't know where to get officiallly educated on-line to deal with propane.

Next time you may want to consider U-Haul. Their people are trained and certified and the rates are competitive. You can go on line and find the rates ahead of time(the rates will vary between locations).

Yes, please (anybody who's tuned in) have your tank/system
serviced by a real propane service facility. The Kwikee-Mart
down the block with a big propane tank and a guy with a
mullet wearing shorts and a tank top is NOT a propane
service facility.
> I don't know where to get officiallly educated on-line to deal with propane.
Here's a place to start:
There's nobody better in the business. Manchester's folks
are great. I've been to many of their service seminars for
the RV industry, and they know their stuff. Follow as many
links on their Website as you need. By the time you're
finished, you'll have a basic education on propane, systems
and safety.
Propane is serious, fire is final.

Dave- you can go to www.propane101.com for all the info on propane and do a general search on the internet under "purging a propane tank" and there will be several sites with info FYI - I found this on sympatico.ca - I am an RV tech currently living in Toronto- hope this helps!

Just an odd question:
Do you know if the tank is really empty? Do you know what is in the tank? It may not be propane.
The only reason I bring this up is, I have had a BBQ tank half filled with pumping oil. (By a service station with a big propane tank.) When refilling, it wouldn't take very much propane either.
Just a thought.... I have one now and then.

I used the tank with only propane for many a year..It became contaminated with air somehow and would not take liquid propane. I replace the filler valve thinking that it was bad. Once again, opening the tank to air....I will take the mh to a professional propane tank filling establishment....They are knowledgable is such matters.
Apparently, there is a purging process taht must take place before the tank will take liquid propane.

idone, I didn't mean to imply that an opened tank needed to have the air purged in order to be filled with propane, but that if the air isn't purged whatever appliance is used won't work very well, I would also suspect that a place properly trained may know why your tank won't fill. I suggested you visit a propane service facility. Bob deK says Uhaul places should have technician trained on propane. Propane is "cheap" try whatever place is most convenient for you.
I used Superior propane in Maple, near Toronto but I don't see them anymore where I thought they were. BTW, they ALSO had a big BANG many, many years ago.
Following proper procedures and personnel(sp) training is a BIG deal in Ontario because of the SUNRISE explosion 2 years ago.

i don't see that as a problem. i've had mine apart with valves removed and air able to enter but have no problem filling it. my problem is that it leaks out.

Are you taking it to the same place every time to get filled?
Maybe try a different place.
Just thinking it my not be you?
I resealed the valve on my old SOB, emptied the tank, took out the valve, resealed it and refilled it.
When I filled it I figured the air would come out the bleeder valve. worked fine.
The SOB had both a float and the bleeder valve, couldn't over fill it if you wanted to
