Propane tank (grill) question

[4mydogs]

Got a "new" tank from one of those tank swapping services and hooked it up tight. When I turned the valve on I immediately heard gas hissing. Usually there is just a quick "pft" and then no hissing. This time there was a steady hissing and I could smell the gas. I turned the valve off and disconnected it from the grill, and then tried turning the valve on and the gas came out without being connected to anything. Is the tank bad?

What size tank are you talking about? But regardless of that, if propane is escaping when you turn the valve on, yes, there is something wrong with that valve! Get it serviced immediately for safety sake!

It's a 20 pound grill tank. I turned it in for another and took the new one home, hooked it up and danged if I couldn't hear hissing when I began to fire up the grill. So I shut it off and waited, and then when I turned the valve back on I could hear hissing -- this was with the regulator hose connected. So I just came from the hardware store where I bought a new hose & regulator. Odds that I would have had a bad tank AND a bad regulator? Slim, I think.

If you haven't already, next time put a bit of dish detergent in water and apply to the area where you suspect a leak. You will be able to tell easily where the leak is actually located.

Maybe the faulty tank made the regulator go bad. Anyway, with a new tank and a new regulator all is well. Thanks for the replies.

I've had the pigtail hose crack when I changed tanks before. The old hose was fine until I flexed it to change tanks. Glad you got it fixed.

Always turn tank on before connecting hose that will tell you if its leaking. Turn it back off before connecting. if you know what your doing you can use a small flathead and check that the plunger is seating, you can depress the spring a few times and they will usually seat. The brass around where nippple seals as it pushes plunger down can get buggered up as well or sand/dirt get in and dont let brass nipple seal.
