Sequence Reefflo Baracuda

[SuperFudge]

I atleast like to run the first part flex, up to the valve and union.

It best to place a union, then the ball valve on the inlet lines in that order, and vice versa on outputs.

If your pump is oversized (wich is best) then i actually like to run rigid PVC after the unions and valves, that way i can tuck it all up tight or beside stuff rather than in my way.
It also makes for a cleaner job.

On OM`s it depends soley on the version drum you have, that would decide for me what type of pipe to use.
If its version 3 Drum , you will want to use spax flex as much as possible on the outlets...This drum version does not like any back pressure, and on a big pump like the 'cuda its hard not to do.
Version 2 i would use either spa or rigid, whatever you would think is better for your scenario...it better drum for the big pumps.

I run 2 OM 4ways, each getting 6000 gph, version 2 is the only option for me, or i would have to opt for more ports open at a time.
