[Amps] water conductivity and hose length

[Herzog]

I recommend that a water filter be installed along the loop.
Get as small a particle collector as you want to afford.  This keeps 
severe crud from electrolysis, chemical interactions, and impure water.
My employer learned this after several thousand dollar's  failures.
I recall a one micron filter; but it did not add much pressure drop.
Probably good to back-flush it every eon or so.  K2LB
