Okay so in building my house I was explaining to the plumber how I want piping running from my fish room (in the basement) up through the walls to where the tank will be above for both my return plumbing and my overflow plumbing.
My question is, my Reeflo pump has a 2" outlet...would I be okay if I had the plumber put 1 1/2" piping in the walls? I plan to manifold off some flow from the return before it goes back up to the tank for my equipment in the sump. I figured the 1 1/2" would be all that is needed once I've robbed some flow from the pump through the manifold.
Am I right or should I have 2" still put all the way up. I will be doing two pipes for the return (1 spare for the future if ever the old one got to have issues or got brittle). Once i get to the tank above, the return pipe will be split into a Y of 1" pipe to go as a loop over the eurobrace to the far side of the peninsula. I know that may not make sense by description but if I could draw the picture I would.
