looking at running a 4 inch drain for my super sump and tapping into it with uniseals instead of expensive 4" fittings. I'm tapping atleast 16 lines into the 4 inch drain that would be about 200 in fittings vs 40 bucks for the uniseals. not to mention easier instillation. Anyone use em and have any ideas? The pressure on the system will be gravity only no additional water pressure as its an overflow drain.
 
I've heard they are better suited to plastic and rounded tanks such as garbage cans for holding water or filtration. They apparently are hard to put pvc through and with glass it might cause it to crack with the force you have to put to get the pipe through. Though with needing 200 fittings id say order a couple and try it out on a couple ~10gallon tanks and see what happens.

I'm sorry I didn't detail my intentions well enough. The tanks would feature regular bulkheads. I will have a 4" Diameter pipe running along my wall all my tanks that are on the same sump will drain into, I wanted to use these to generate an easier cheaper union between a 1" and 4" pvc where all the tanks tie in. I will need to tap into the drain pipe about 16 times and that will cost me 200 dollars in regular fittings, vs 40 dollars in these uniseal solutions.

See this image, here is what I want to do:

hope this makes sense.

We ran a couple of tests this weekend to make sure we had proper flow on our over flow designs. We did also attempt to test the bulkheads on glass first with our 125's that are already drilled, the tanks were up on the stack so it was impossible to push the pipe through, simply couldn't get the leverage. We can't put them on the put the tank on the stack, it won't have the sliding clearance on the bottom it needs.

We will be attempting to plumb either the return or the drain for the entire super sump next weekend. If we are lucky both. Then you'll see the trail bulkhead use. My dad's birthday surprised me so I kinda lost most of sat on those celebrations.
