Thanks Gresh, yesturday I installed union valves on the flap valve (I thought of the same thing a little late), yes the mini ball valves are for equipment, should I run a separate pump in the sump for the equipment and not be apart of the central system? This is some very cool advice thank you, I've been waiting to glue everything together forever. The thing about the flap valve is that I have zero verticle space or that would be ideal.
Thanks again, anything else you see?
