Return Fittings

mpatient · Jan 28, 2020

Planning the plumbing for a 90 gallon. (Shadow Overflow, Bean Animal) The drilled return hole fits a 1" bulk head. I am finding most loc line parts are 3/4". I would love to see examples of the fittings used in a 1" return line in to the tank. The tank will not be dependent on the return line for flow, so I am not married to loc line if there is a better option. Thanks!

You could always use a 1" - 3/4" bushing at the bulkhead and then use 3/4" pvc for the return.

This is what i was thinking, but would that cause any flow/pressure issues going from 1" to 3/4" at the point where line enters the tank?

Not enough for you to notice.

Have you looked at the 1” VCA random flow generator? It has been a while since I looked at it but that might be an option.

There is some 1" loc-line out there.
I had a link on my pc, but recently retired it and lost the link.
I'll look for it.
