In the vehicle, it quite easily achieves a kill everything temperature, keeping even an active biological mix reasonably sterile if it doesn't sit too long.
Cooling a spindle motor does not generally reach those temps but the small elevation in heat it does achieve encourages the biological contaminants to grow faster. So I might setup a cron job to run the pump for an hour in the wee hours if lcnc isn't running, and it would be easy enough to dump the return line into a leaky spoon, which if it gets enough flow would activate a micro-switch to tally enough flow, and have the cron job send me a change the filter email if, say 5 minutes before shutdown, the switch isn't closed. Or yell if the switch is closed before the pump starts because the hole is plugged. It probably won't happen, but that is what you get when I let my imagination out to play w/o a chaperone. ;) Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
