LOL Why do they pick on Bill for? He's a nice guy.
The flow rate data is something that is needed for this site's testing. It would be a nice touch. I got one question from you guru's though. Let's say if PH tested with one pump and then switched pumps. What effect would that have? Now what about different head ratings? How do you regulate the flow? When you regulate the flow does the head rating change with the pump? The pressure the pump will produce will still be the same no matter how you regulate flow? Right? hmm...It takes a certain amount of pressure to produce any given flow rate, so the head rating of the pump doesn't matter much with testing. As long as you have a decent pump to encompass a full range of pumps?
I think im confusing myself which wouldn't be the first time.
