Plumbing... Need help

Unless it calls for 1" pipe, you should probably leave it at 1/2" - if you take it up to 1", then your headloss is going to be even greater as there's much more water that the pump has to push up against, so you will get less flow.

i would use 3/4" thats fine.. if you still need the adapters email or call us.

+1. i wouldn't change the diam. of your pump output. bigger pipes are only really beneficial for drains.

It's not like if you go bigger, the pump will pump less. It's just that the amount will flatten out so after a few sizes it's not worthwhile going bigger.

Again, Brass=copper (very bad)

Actually this isn't true even if you increased to 3' Diameter pipe you would still have the same flow believe it or not it is fact.

And same head pressure for the same height. head pressure is a combination of friction loss from length of pipe, and the height the water has to travel. A larger pipe will have less friction loss for a given flow. But that may not make a difference, depending on how much your allready flowing

Oops, I mixed up flow and velocity And to think I studied blood vessels. . .

Bigger diameter pretty much means more flow in almost any circumstance so bigger is usually always better.

1" sounds pretty good for that size pump, you should be able to find a 1" x 1/2" PVC bushing at most hardware stores, pretty common part but any plastic will work fine. Avoid brass as already stated as it's simply a copper and zinc alloy; copper is poisonous to coral.

pvc sch 40 is what you need, corix is the best place for this. however like said before , increasing pipe size is not necessary. increasing pipe size will give you the same volume at a lower psi, make sure you install a check valve. your volume will be determined by your pump.

put some thought in your return layout and sump size to see if you can avoid using a check valve
