Re: [AGA-Member] CO2 tank squealing!!

Hi Heather this is Mike. The problem you are experiencing can be caused by a lot of things. How and to what pressure they filled it is usually the problem. You can overfill a tank without its burst disk going (tank safety pressure valve) but the regulators are set lower. I know this personally because I have overfilled a few tanks in my life. By the way how far did you jump or how fast did your heart race when it first occurred. Best bet is to take the tank back and ask them to check it and your regulator because if they did overfill the tank the safety valve on the reg may stay open.

  Subject: [AGA-Member] CO2 tank squealing!!

  Dear  CO2 gurus:
  I have a gas tank question for anybody around tonight.
  I've got one of Troy's Milwaukee regulator/solenoid/bubble counter.
  I've had fairly good luck since I got it going--lots of algae due to 
  fertlizer issues, but tests were finding the pH/GH/CO2 okay.
  The CO2 tank went empty a few days ago.
  I just replaced the 10 lb tank tonight.
  They were storing their tanks outside, and it's been "frost on 
  windshields" weather around here for some time.
  I brought the tank inside, and hadn't had time to work on it until now, 
  since it's warmed up.
  I attached the regulator, filled up the bubble counter and attached the 
  CO2 airline, turned on the solenoid, and tried to open the main tank valve.
  Before any pressure shows on my  the emergency release on it squeals 
  horribly, and shows no signs of stopping after letting it howl for at 
  least a minute about five times.
  I'm thinking this may be an overfilled tank, or a malfunctioning one, or 
  there may be a blockage in the regulator.
  I'm also not sure if this is "dangerously overfilled", get it back out 
  in the garage NOW, or if there's just something blocking the regulator, 
  and what I should try.
  I would like to talk to you first, as Airgas won't be open until 
  tomorrow, and may not understand what I'm trying to do.
  Thanks--any advice welcome!
