[Amps] water conductivity and hose length

[Jim Tonne]

The water filter does not need to be "in series
with" the entire flow path.  You can take just a
small amount of the water via a detour and run
that through a small filter.  The object is to
eventually run all the water through the filter
where stuff is trapped.  Perhaps every tenth
pass through the system a given little bit of
water will run through the filter and get cleaned.
I learned this while working on   *big*  shortwave
rigs.

Eventually that filter will have to get flushed or
otherwise cleaned in some manner as K2LB
said.
