I have been running mine for less than 2 weeks, around 5bps. This morning the tank gauge shows nearly empty (dropped from around 50psi)! I suspect it could be the gauge at fault as the regulator gauge was still showing 20psi and it was still bubbling away OK. Will find out tonight!
How long do others fire extinguishers last for a given bubble rate?
