Hey guys, I have 3/4 tubing for the return line from my pump to my tank and when I cut the pump off I have a bit of siphon from the display that adds to my sump. I am having the hardest time finding 3/4 barbed check valves. Do you all know of anywhere online that sells them? I have only been able to find pvc check valves and I really don't want to buy barbed adapters for all that mess.

IMO Check valves will work for awhile but they are made to fail so I would not depend on a check valve for the long run. You can get them at Amazon but I would try to figure out another long term approach to the problem. Maybe less water in the sump if that is possible or an upgrade to a larger sump.

Installing a check valve is like putting on a condom on a first date and expecting the same condom to work at your 5 year anniversary... It could work - but are you really going to risk it?
Put a loop in your return that comes above the surface of the water and drill a small hole - this will create a siphon break and stop the water coming down.
If you want to do both -- because between the check valve and the siphon break.... only one is going to make sure you don't end up with more kids spilling on your floor
at least order the check valves with the unions on each end. And order several. I use check valves so that I can do maintenance without dropping water levels and for an automated 2 pump back up system. I have one box of extra check valves ready to swap, I have another box soaking in vinegar and I have the ones that are installed on the system.
But if every single check valve fails, I only have about 1.5" of water rise in my sump (it's a 340g sump so 1.5" is some water).
