Waterbox 130.4 Replumb

[RoronoaZangetsu]

I am looking to see if anyone has any experience or guidance on how to upgrade the existing 3/4 inch plumbing on a waterbox 130.4. I want to take advantage of a new Vectra M1, but the current pipe sizing would restrict the flow. The goal here is to replace a failing Vectra S2 which is running at 100% all the time with a stronger pumping at 70% power.

I am not sure how to replumb this thing. Help?

Do you need to? A 3/4" pipe is still capable of close to just shy of 1,400 Gph.

idk maybe not, but everywhere I look every pump wants 1 inch or even more. Downstepping the outlet seems like it would add head pressure as well as noise. Thoughts?

I think you’ll be good with a 3/4
I’m running a 3/4 on my 130.5 and it runs great. I know you have a M1 but it’s not that much different.
