I'm looking for a mag 9.5 return pump I have one but whoever had it previous didn't take care of it and even though It works its all rusty and in bad shape. I have an 1800 thats in great shape was new last year that I could trade straight up for it if anyone has one

Ask Jason at easy, he might be able to do something for you if no one else has anything

Why not use the mag 18 and put a ball valve and a bypass on it to divert some flow back to your sump. It would help keep your sump clean of detritus as well.

I'm still trying to figure out how the hell I'm gonna have it all plumbed I've never done it before first sump ever and I'm redoing the one I got. I know I would put the ball valve after the return but what do you mean by a bypass could you give me a photo example?? |

Something like this That's exactly what I mean by a bypass |

So basically putting a T in after the return to push the water to not only the aquarium but somewhere else in the sump?

Exactly, it let's you release the extra water pressure from a larger pump directly back to the sump instead of overwhelming your tank overflow system. Just make sure you are able to regulate the flow through the bypass via a ball valve.

So should i still be able to use 1.25'' PVC or do I need to go bigger?? Also when plumbing the drains can I join them or do they both have to separately go down into the sump? This is the design I think I want to go with it doesn't look too technical and I think it would work for my setup what do you think?  |

That's the basic setup but 1.25 PVC is way too big. The mag 18 only needs 3/4 PVC all the way to achieve the head pressure you need. What size tank do you have again? Your better off joining both drain pipes for the overflows together into one larger pipe. The more pipes you have going to your sump the more cluttered it will be. Both my eshopps 1000 overflows have two 1inch bulkheads each, so I have a total of 4- 1 inch bulkheads total plumbed into a 2 inch drain pipe to my sump and it handles all the flow from a water blaster 10,000 model pump that's pushing 2,600gph in my 75 gallon.

+1 to Ryan's last post.
I have 3 overflows, and each one goes to the sump. It's cluttered, I wish I had plumbed them into a single, larger pipe.
Also, I love the idea of diverting the excess from the pump back into the sump, I currently just valve back the main flow as needed, and putting it back in the sump would have several benefits. It's probably easier on the pump that way also.

So so I need to make them 3/4 from the overflows and once they join adapt to 1 inch or something down to the sump? My other question is can it just flow right through the bulkhead which mine are drilled through the back of my glass or do I need piping right there In the overflow box? |

Your pump pressure line to the top of your tank only needs to be 3/4 PVC for a mag 18. You can make your over flow tubing any size you want as long as it handles the entire flow of your pump. Most standard overflows are done with 1 inch bulkheads so you at least need to start with that and go up from there to accommodate multiple overflows into one pipe to drain back to your sump.
