I redid my plumbing on my tank, since I built a sump from scratch. I finally got it put in this weekend. My drain pipe use to be short. (to the blue line) but I put a longer in because if I didn’t get my filter sock changed out soon enough water would splash out so I made it so it goes into the sump a littler further. Now my water gurgles. The water in my overflow box drains like a toilet and it’s super loud and annoying. Is it because I made the bottom pipe longer? I made the air vent hole on top bigger and also stuck an airline tube down the drain just too see if that made a difference and it hasn’t. I have tried putting more water in the sump to cover the bottom of the pipe in the sump and also took out water so the bottom of the pipe would be exposed too air. Why is it doing this? If I cut the pipe and make it shorter will that really fix the problem. I did switch which hole drained and which returned but I don’t know why that would make a difference. Everything else is the same.
