ok so when the bottle was filled the bottle heater would warm up to 900-950 in a heart beat, im wondering if te bottle may be empty, because 1) the pressure wont go above 600 and 2) when i purge it wont make te cloud like it used to, so im thinking there maybe oxygen, but no nitrous....what do you guys think?

 

1. full bottles generally heat up quicker
2. weigh the bottle and compare with the sticker stating the empty/full weights --best way--
3. hot or humid days you wont always see the spray plum on a purge
4. --last resort-- hold the bottle AWAY from you horizontally, with the opening facing up, now tilt it down 45 deg and crack it open a bit, if you dont see spray it's all air coming out first


give that a whirl and let us know; then we either solved ur prob or we can start from there and trace back
good luck

 

It's usually opposite for me. When it's about empty I can hardly get any pressure out of it
