The adjustment was meant for the Herbie, not the durso, my mistake.  Thats a good idea for the Sump end of things, the salt creep was terrible when I ran my durso and the noise was unbearable.  Good to see you put the emergency drain in.  I was told I wouldn't need one when I first started in this hobby … boy were they wrong lol
