Gas for Cooking

Have a relatively simple question I believe... using propane for cooking(just have a 100lb cylinder) and it ran out. Gas company delivered, but they want to send a tech to check the line for 40 bucks. Is that necessary? The line is only 3 years old and was running just fine when it ran out a week ago. Is it fine to just turn on the tank and save the 40 bucks?

You could probably test it yourself-just get some pipe fittings including a ball valve (to seal the line), a schrader valve (the kind like you see on a tire), and a cheap pressure gauge. Use a bike pump to put 15 psi or so into the line, close the ball valve, and wait an hour. While you're waiting put some soapy water on all joints to check for bubbles. After an hour if there's been no bubbles and the needle hasn't moved on the pressure gauge, you're good. That's what the $40 tech visit would entail.

I have run out of propone a couple times and my supplier has never suggested that a tech be sent to check the line. Sounds like your supplier might be having a slow week...

I would report them to the Better Business Bureau.

May be a local code, my company told me that if the tank runs empty they're required to pressure test the line before refilling the tank.

Well leaking propane is no joke. Much more dangerous than Nat Gas for instance, but if your nose works you've got a pretty good leak detector right there. The odorant is strong!

So if my gas grill runs out I have to pressure check the line???? I fill my own tanks to run my cook stove....But never heard of such a law to pressure check a line if you run out but I don't know a whole lot anyway....I live in Maine....Got no time for such nonsense.

Unless his usage appeared really high compared to his previous usage, indicating a leak. The smell test should work, although I remember reading about a batch that didn't get the stink installed, thus didn't smell when there was a leak.

We have a 100 lbs tank, but use it only for cooking on the stove, The oven is electric. Just using it for stove cooking, we topped off this fall at about 3 or 4 gallons. It would take us about 5 or more years to run our 100 pounder dry. You may have a leak if your only using it for cooking on the stove.
They should have checked it out when they delivered.
Put some soapy water on each fitting and look for bubbling.

The idea is that if it ran empty then you must have a leak because you had plenty of warning to fill it up. The unexpected depletion of your fuel tank indicates a leak. Pretty crappy if you ask me. Might even be a ploy to sell more gas since you will be calling all the time or setting up auto fill to prevent this "fine".

I'm not a fan of the soapy water test unless you have failed a pressure test. Professionals pressure test and if it holds, then it holds. If pressure loss occurs, you can then try and search it out. They sell premade pressure testing rigs with the schrader valve and gauge at home depot. You can use this rig to test plumbing and gas.

When I nearly ran out last week because the gas company was later delivering, I called and told them I was out. I hadn't actually run out but it was at zero on the gauge. They wanted to schedule a tech to come out and relight the pilots. Told 'em no, I could handle pushing a button.
