Connecting Up Pump to Wet/Dry

Hello everyone - I would appreciate some input on connecting a pump to a new wet/dry filter.

I need to drill a hole in my new wet/dry acrylic filter and install a bulkhead to connect the suction line to my new Little Giant external pump.

Are there any tips you all can provide? Do I want the pump to set on the cabinet bottom, or should it be attached to a peice of wood or anything? Should it be raised any?

Also, if I route the discharge line BELOW the water level, would a checkvalve prevent a siphoning back of the entire water level during a power outage, or should it be located above the water line...?

Should I use all rigid PVC, or flex?

I know, a lot of question, LOL.

All input greatly appreciated...I have never done this before.

Thanks,
Mitch

Thnaks for the reply. I was planning on allowing enough reserve capacity in the wet/dry filter to allow for the pump to shut down.

I will have to test everything before hand - and your advice is most helpful.

Thanks!
