Please help. My hand is bleeding, I'm tired. I hate pipes. I'll give all the details so hopefully someone will know the fix. I fell asleep in the basement and woke up to the sump pump constantly cycling. I knew this wasn't normal.Then it rained. It was obvious the water was coming in through the discharge pipe and not the intake pipes--and after a rain storm, there was a ton of water and it made me feel like this needed to get fixed right away. Before it rained, the water kept coming back in, but there either wasn't much in the discharge system or it came back slow. After the rain, the basin would backwash very fast. Knowing nothing about plumbing, I did some research. I concluded the problem was the check valve. I identified it and replaced it, which was a pain. Turn the pump on and...same result as before. All the water flows back in the basin. What the hell? The new valve is oriented properly--flow is vertical, going away from the pit. There's another check valve on the back-up system, this is a separate pipe and don't see how that would possibly affect anything. The water is returning to the basin a bit slower than before,--that's something, but it doesn't really do any good in the long-run. Is the new valve defective? Seems unlikely. Did I install it wrong...seems more likely, but it's a slip on, don't know how I'd mess it up. Was the thing I replaced not the check valve, even though it said FLOW and the home depot confirmed it was a check valve? Is the Everbilt compression valve a lemon? I think it's a spring. Is there a piece inside I have to take out or something? Would a slight angle mess it up...I didn't really check, looked straight. Is there some other explanation? Please help, I'm about to take a hammer and destroy the damned system. I took it apart again, thought a re=install might be worth a try. I found after it reaches a certain level very quickly, it fills back up at a drip pace, which is a lot slower than before. I cut pipe a bit to make it more even, it was a bit jagged. I refitted the Everbilt...and it sprayed me in the face with holes in it. It's obviously a piece of garbage. But before that happened, it seemed like it was preventing backflow. Water in it wasn't going down. But before I re-did it, I could hear and feel water flowing through it and down. What gives?

I have a home inspection scheduled for this friday and i dont believe that the setup for the washing draining into sump is up to code please help
