Where is everyone #5

I love the Manitoba mag wheels but at least he didn't put chrome covers on his nuts.

 

Interesting you should mention that. There are people that make up a 3D printed Battery connector so that you can wire those thiings to take like a Dewalt battery, that's interchangeable. I was looking at it, myself to set those pumps up on 3 separate setups and being able to change/charge the battery was the way I want to go. Something like this, allows you to mount the battery reciever on the pump, and you just insert the battery. There are different makers from simple to complex and different prices that you can search for, using the search term: dewalt 20v battery adapter 3d print ....or another battery type you have. They also make the printing files available if you have your own 3D printer.
This one is available on Amazon in a 3 pack for a use case like mine for about $16.99, prices vary depending on who has it, what it looks like, etc.

 

I agree and I like your method as well if you're able to spend the time and focus on only that and get it done fast, but 19-20 GPH, is nothing to sneeze at either, especially if you want to do other things while waiting, if you're not able to fully focus on only that task for the time you have available. Filling a 5 gallon bucket every 15 minutes gives you time to go get coffee, hit the head or have a smoke break if you're so inclined. Different strokes for different folks. It's just another option, a low cost one as well.
