Jeff5614, I noticed in a post that you run a Sedra 3500 and you said that it was easy to connect. May I ask how you connected it?
I just bought one and I had a hard time getting anything to fit in the input of the venturi. I finally found a PVC connector that just barely fit. Anyway, after connecting it, I tried to test it in a laundry tub. I never really got it pumping. I am just curious what you did.
