Plumbing... Need help

ZachAttack · #1 01-04-2010, 10:56 PM

OK, I'm getting a new tank and adding a sump. I have a pump that is only 1/2" output so I am going to put an adapter on it to go up to 1", giving me more volume and less likely hood of obstruction. I need a Male - male threaded piece, one part goes into the pump and the other threads into the adapter for 1" pvc. However, I can only find the male-male adapter in brass or poly ethylene... Are either of these reef safe?? If not any suggestions on how to change my plumbing from 1/2 to 1"????

Definite NO on the brass.

You should be able to find the PVC piece you need at Corix Water Products. They are located on Golden Dr. in Coquitlam (just off United Blvd). They have everything there.

Why not just leave it 1/2"? Its never caused me any problems. If your pumps suckin up something big enough to clog it... You got other issues to fix.

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. . .
