dart pump question

[christyf5]

the 6' is vertical but by the time it comes out of the pump and then goes up and tees off to each sea swirl theres a whole lotta elbows.

Second, are you counting each output elbow of the sea swirl as a inline elbow. You should be counting each elbow in the "path" to the tank.

IE: if your return splits into 8 lines and each has an elbow, you really only have 1 elbow between the pump and the tank.

BTW: I had a dart, and now a snapper and I do love those pumps.

wow this was like another language to me. the return was basically splitting into two lines each having a crapload of elbows. Heres an artistic rendition of what I'm talking about. Yes I know my talent is pretty impressive




I will be using 1.5" pipe, I'm thinking spa flex will likely be the way to go anyways as hillegom mentioned, there will be less friction. As for the elbows that are actually part of the sea swirl, I had totally forgotten about those.

Thanks for the help guys, keep it going if you have any other suggestions! I've been living in submersible mag pump land for the past 5 years, its as far as I can think
