GPM vs Line Size
The March 809 pump is rated at 7.5 GPM. This flow requires a 1" line, correct?

I had a handy chart that listed these specs but it has been a while since I've seen it. Just trying to pull it from a memory with corrupted files...

Yea I hear you, most pump ratings are for ideal conditions. Compromise those conditions, and results vary widely!

Found my cheat sheet!

For those interested in line sizing:

1/2" = 2 GPM

3/4" = 5 GPM

1" = 10 GPM

1-1/4 = 20 GPM
