Two pumps with one thru-hull fitting?

Re: Two pumps with one thru-hull fitting?

Your last paragraph, I think you meant putting two in parallel. Putting them in series would allow them to have a small boost in pressure, but little boost in flow. Putting them in parrallel, assuming correct size discharge hose, will allow them to flow just under their combined rated capacity as you said.

Othwise, great explanation. Thanks!

You're absolutely correct. Pressure=series and volume=parallel. After the math (and maybe a beer or three), I just wasn't thinking. Thanks for the correction!
