interlinking sumps

cool thanks, i shall do that then

i dont want to sound dim but how do i use a bulkhead? how exactly does it work?

Thanks
Matt

The bulkhead has a rubber gasket on one side. The gasket is the water seal and should be on the water side of the tank. The other part of the bulkhead is a threaded nut that clamps/squeezes the rubber seal to the glass. The nut should be on the dry side of the glass/acrylic.
FYI: Bulkheads are usually sold with information on the size hole that needs to be drilled and also the size of the bulkhead. So if you wanted a 1" bulkhead it may need 1 7/8" hole size.

Go with the largest size hole you can fit. I have two sumps with a pump in each. The sumps are connected with a 1" bulkhead and that's fine to keep the water level the same but if a pump fails then one sump will over flow and the other will dun dry. The capacity of my 1" bulkhead is just to small to keep up. If I could do it over again I would of gone with a 2" bulkhead!

When you order the bulkhead the site will say how large to drill the hole. I just installed the 1" so I remember. A 2" bulkhead could be, and most likely is, different. It might be 3" or 3 1/4? I just wanted to give you an idea how much larger a hole will need to be. I thought for sure when I cut the hole I would have enough flow but after the bulkhead was installed the hole looked a lot smaller - not good in this situation

Also bulkheads have different thicknesses. a 1" Schedule 40 is thinner (smaller hole) than a 1" schedule 80. I always get the threaded bulkhead and do to the stress of tightly threading my plumbing to the bulkhead I like to go with the heaver schedule 80 bulkheads. If your going to glue pvc directly to your bulkhead then you can go with the cheaper, thinner, schedule 40 stuff.

Yes

Will you be having one sump on top of the other or side by side?
Sorry I didn't see this anywhere going through the posts

You could do something like I have and put one in the right side of the stand higher up than the sump in the left side. Run the hard PVC under the shelf in the middle and you would not even know it was there?
