If I use this foam in a sump pump do I need to drain the well first?
Invade Bio Foam in a poly foamer.can be applied to a sump pump and you would not need to drain the well but you can. You should treat over multiple days with the foam and it will eat the "gunk" in the cracks which should eliminate the breeding locations.
