Ok I'm going to do a get valve mod this week end to my Octopus NW-200. I got this picture I'm going to use to copy the plumbing layout. My question is the valve is really high. Can I lower it to the sump water level? or just above. My sumps level is only about 6-8" and the vave is about 12-14" in the pic. I dont want all the water comming down creating more bubbles. I wil still run the riser pipe up to the collection cup.
