Hi All, need some advice:
rEvo III, my partners o2 orifice bleed valve is making a buzzing sound - much like a small alarm clock. We have done a number of checks.
Flow rate is fine, IP is within range checked on two independant IP gauges. We got the units in September this year done about 20 - 25 hours, religious with cleaning. The noise coming from the orifice is audible from the next room...it is loud...Anyone had this issue? Any ideas on resolve because carrying an alarm clock on a dive is no fun .
Cheers Helen Grigg
