Ok, I managed to get all the fittings except 1....it was the incorrect size. We went ahead and put it all together, the one fitting needed was from the bushing to the water pump, so needless to say, we don't know if it all works. I went ahead and used the flex tube for now. Will probably change it at some later date to pvc
. I was a little nervous about not being able to shift the sump if I needed to ...silly reason, but such as it is. My big concern now is because i have no experience with sumps, I am not sure if the lines will work. The lines from the overflow INTO the sump, have dips in them and rises to the sump bushings. Does the water flow hard enough to overcome this type of thing? I could not come up with a way to shorten the flex hose.
