Did you use slip/slip or threaded?

Everything outside the tank except for the caps on the top of the down pipes is slip/slip. Inside the tank the elbows are threaded as well as the locline. I used unions to make sure I can disassemble as needed.

The check valve I got has no metal so nothing to rust and fail. I also have a screen on the pump intake which should prevent any critters from getting in there. Plus, I do have room in the sump in case it did fail and the tank siphoned down to the return level. I was maybe a little paranoid and tried to double up safety features where I could.
