Question Should you overfill lp tanks without a + stamp?

[sharknutz]

Question: Would you overfill lp tanks (85's, 95's, etc) if it didn't have a + stamp?

Let's assume for the sake of the discussion the tank has a burst disk capable of whatever pressure you're filling to.

Edit: pump it up referring to a N FL cave fill of 3k +

You are going to have to define "overfill."

Do you mean to the plus rated pressure (2650) or to a cave fill of 3K+?

ETA: nevermind, I see you have that as an option!

I don't overfill, but remember someone I knew who posted on FB a picture of his spg showing 3800 psi on an LP tank. Way to invalidate any dive insurance bud!

We're talking N FL cave fills 3000+

From a "by the book" interpretation, no. Fill to rated pressure only. In a real world scenario - my lawyers have advised me to not answer the question.

Smart man, I'll caveat this is purely a thought experiment/discussion and by no means advice for anyone to overfill a LP tank beyond it's rated pressure.

I voted for "slightly pumped"...... As for the post above about someone pumping to 3800.......I'd say that's his or her business as long as they have their own compressor, live all alone in the woods, don't have a dog, etc......and never take that tank anywhere near another person unless that person knows about it and is cool with it.

Just curious....... why is overfilling a tank called a "cave fill"?

If it didn’t earn the + rating, I wouldn’t like that.

With the + rating I’ll overfill to normal cave diving pressures and not give it a second thought. Thousands and thousands of tanks are overfilled annually and it’s fine. If this was a problem, it would be known by now.

 

[runsongas]

depends if the tank really missed the criteria for the + or if the hydro shop was just lazy.

3300 - 3600 all day long. Just depends on what dive I'm doing.

The plus rating is only good for 240 psi though? My hydro place did not give me the +, but the papers that I got back clearly show that it could have gotten it. I just didn't ask, and they didn't do.

I just can't imagine a tank would physically pass for 2400psi but fail for 2640?
