Doc, mine actually has a 5 HP motor, but it’s on a 2 HP model DC (very long story). I meant to mention that in the info, sorry. Just a comment on the grounding….it might help with personal comfort (not getting your butt kicked if you touch the pipe) but otherwise has no value. I grounded my first system years ago, and quickly found out that it was mildly expensive, but more importantly a colossal PITA everytime I made a change to the system. I scrapped it fairly quickly.
