Propane tank not flowing 100%

Its an old 60 PSI regulator. Its frozen wide arse open and has never been adjusted. Regulator on grill, no idea.

Two tanks, two regulators, same results.

I am not sure if the bleeder valve/screw has anything to do with the tank flow.

I think you need to find a place that sells propane and propane accessories.

adjustment screw that they used to fill the tanks all the way.

This screw is there mainly to ensure the tank is not fully filled with liquid propane. It shouldn't have anything to do with your problem.

Honesly doubt anything wrong with tanks seeing as both are giving you same result. Some trash may have gotten lodged somewhere giving you the trouble. The newer screw on gas connections have a limiter built in that that either may not be giving all you need or have some debris clogging it. I'd remove it from the hose and screw directly into tank and crack the valve to check how good its flowing.n I have also removed the limiter which is just a bearing with a spring before. Think I drilled it out.

Got two of my tanks filled last weekend for a few boils. Neither tank would flow 100% afterwards. We got the pots to boil, barely. I suspected the regulator, but I put both tanks on my grill and they would barely light 3 of the burners.

Are the vales on the BBQ Pit or burner open when you open the bottle? If so, you need to reset both regulators. Hook up the bottle again, open all the valves, close them, then open the butane bottle.

I couldn't get any flow out of my tank after being filled last week. I bled some gas out of the flathead bleeder screw, and that fixed the problem. Possibly tank had too much pressure and the internal valve couldn't open. Maybe on yours it cant open enough when the hose is screwed in. LINK

Weirdly, I had this same problem on my grill this week. I had some people over while I was grilling and the tank ran out. Made a quick trip to Rouses to grab a new one and when I put it on, my grill would only heat up about half way. Still got the job done, but took double the time.

I haven't tried to figure it out yet.

The following is a description of the function of the check valve in the tank:

The check valve is installed to detect hazardous leaks in your propane tank. When the tank hand wheel is turned to open, the liquid propane travels through the check valve and the barbeque grill regulator to fill the hose attaching to the grill manifold. Providing the barbecue grill valves are in the “off” position the propane stops before filling the gas grill burners and the pressure checks back to the valve. If there is a leak in any of the fittings that connect your propane tank to your gas grill, the drop in pressure is noted and the tank goes “into check” which restricts or stops gas flow.

It's the tank, lay it down, sometimes that works
