Is the lid needed for suction? - No. The lid is there to keep crap out and I use it to place the lifter someplace
Does the lift need to run 24/7? - No. As 2Q stated, if you submerge the end in the back of the overflow it will create a syphon in the pump and you can turn it off. BUT, there is quite a few bubble build up within the "U" shaped overflow and those bubbles might stop the syphon. I run mine 24/7 just to be sure that the overflow doesnt stop.
Whats the coonection type to the overflow? - Well, the outside of mine is threaded and the tube i used was not going to fit inside the bulkhead. I had to go on the outside of the overflow's bulkhead. Am I going to take it apart and look at the inside? Not right now. When I clean everything again, prolly friday, I will do this. I cant change my tube though as that tube is matched to go into the sump. That hose is larer than the return hose and I would rather have the larger hose. This way, If I change my return pump to get more water moving through the system down there, I wont have to worry about the overflow keeping up.
Don't worry about my feelings, I was late to the party.
Sorry, I wasn't actually recommending that you should take apart your drain to check it. I was merely trying to point out that when in refference to bulkheads that Slip or Thread style refers to the inside of the bulkhead. I'm glad that you joined in this thread as any and everyones opinions are certainly welcome. Our goal as a team is to come up with the best design possible to give Flower a really kick a$$ set-up.
All bulkheads that are used in this hobby are basically threaded on the ouside for installation. I would however, like to mention for Flower's benefit or anyone else who might be following alongs benefit that simply adding a larger hose on the drain won't actually do anything to increase the amount of flow that your overflow is designed to handle. The best way to look at this would be to think of your bulkhead as a bottle neck. If you have a 3/4" and a 1" drain line then you're still only going to get the amount of water draining through there that the 3/4" bulkhead will allow to pass. I would suggest against installing the hose on the outside of the bulkead, if you intend to use a hose clamp you should be careful since those Sch. 40 bulkheads are easy to crack. The slip style is design for installing a pvp pipe in the bottom of them so that you can run a pvc drain or attatch the proper fittings in order to use vinyl.
The best and probably the only way to increase the output of your overflow would be to simply enlarge the drain opening on the overflow in order to step up to the next biggest size bulkhead. Assuming that the back box on the overlow had the room to do so. It would be simple to do and would be a great way to insure that you're actually achieving the maximum amount of drainage that your overflow will give you. You'd have to take into account the actual size of the overflow as well, and how much water the U shaped channel will allow to pass. But I think you could just to the next biggest size bulkhead with no probs. At the very least it's a little extra piece of mind.
