Query: Easy install!

Everything about the install was very easy. One thing that I had a problem with was the rubber O-ring that is supposed to be set over the drain threads was too thick and it did not leave me enough threads to thread the pump on to the laundry sink. I did not use the O-ring, I just used a good amount of teflon tape and tightened it until it was snug. I had no leaks so apparently the O-ring is not necessary. My only suggestion for anyone who is installing it is to make sure you use the ball valve that is supplied with the pump so you can throttle the amount of waste water that is being pumped through the discharge pipe(the directions supplied show how to pipe in the pump with the ball valve and check valve). If you do not throttle the ball valve the pump will continuously cycle on and off. Once I made all of my adjustments the pump has worked great!!
