3) a 'weep hole' in a flapper valve that will allow a minimum
amount of
flow to keep the water liquid?
I assumed having enough
antifreeze to handle the cold, but I still don't like the idea of having no flow
for any period of time if the primary pump quits. I thought also about
having a high/low switch, so that there's still some flow rather than just being
off. Then of course I realized that it would be better to just use one of
controllers that Davies Craig sells, and be done with it. I bet you could
run that on one of the pump/evap core combos, and leave the other pump on all
the time.
Maybe I can get around
to testing mine today.
Cheers,
Rusty (now officially
using red)
