Flow Check?

jasonmh · May 23rd, 2006, 11:25 PM

Hi all,

I have seen the term "flow check" used on here before, but I don't really know exactly what that means. Can someone please descibe it for me?
Is it checking your valves to make sure they are all open?
Thanks.

AIUI a flow check it to go through the valves making sure they are all open, including suit feed, and stage bottles, working from your right to left. This should be done on the surface, and is also (AFAIK) done at the bottom of the shot too.

Yup - and also after valve drills, coming into contact with something overhead or entering/exiting overhead environments.

Any time you might have knocked/rolled valves AIUI.

More specifically, a flow check is to check all your valves in a systematic manner to make sure each valve is the way you expect it to be (your valves are not necessarily all going to be open at the same time). For example, if you have a problem with one of your valves, you might shut it down. After trying to resolve the problem with your buddy, you make a team decision on how to proceed. Before moving on, you should do a flow check to make sure all your valves are in the position you expect them to be in (the one you shut should be closed).
