Checking with the Public Lab community to see if anyone can assist me with some issues I am having with the bucket monitor.
I had a perfect opportunity to pull a grab sample last week, but could not get the Tedlar bag to inflate. I suspect the failure was because I had left the intake port plug off of the monitor, but there are other questions I have, as well:
The intake port plug was replaced. I think its absence prevented the Tedlar bag from inflating.
Does the black valve on the Tedlar bag need to be closed completely?
Also, what is the valve for and what happens if you loosen it?
Does every Tedlar sample require single-use ferrules and a nut?
Is it correct to assume you need a front and back back ferrule, as well as a Swagelok end nut per grab sample?
Should the pump be set to inflate, not deflate?_
Seems like an obvious question, but I want to verify. Thank you!
