Product Questions

I need the 1". it had said that it works with loc line but loc line is only made to 3/4". So does the 1" reduce to 3/4 local line
Question by: Jason Howell on Aug 15, 2017, 11:19 PM
Hey there,
Thanks for getting in touch with us in regards to attaching Loc-line to this eductor. These are not something that is compatible with Loc-line, and will not be able to attach to it. Please let me know if there is anything else that we can assist with. Thanks!

Can the 1" be threaded straight into a 1"bulkhead?
Question by: Luke on Dec 8, 2016, 9:59 PM
Great question! As long as you have a female thread bulkhead, this absolutely can be threaded directly into it. :-)
Answer by: Randy on Dec 9, 2016, 9:49 AM
What is the overall length and width of the 3/4 eductor, and just the length of the threaded portion.


Question by: Adam Kostera on May 11, 2016, 9:27 AM
Great question! The eductor measures as follows: Length: 4.5" Width (at widest point): 2 3/8" Threads (length): 3/4"

how much head pressure will these eductors create? I have a mag 18 currently pushing 12' of head pressure and was wanting more flow without buying a bigger return pump. Also, my return T's off into two outputs,so I would be running two eductors.
Question by: James Kilgore on Apr 21, 2016, 7:37 AM
Great question!
The Eductor will not increase head height as the flow is still allow through them with no restriction. Only increase flow from the return output. Feel free to let us know if you have any further questions!
