Shurflo and freezing

[maplestudent]

It's the two-stage Inkbird I have linked further up in the thread. My new box is ready to go. Now I can't find anyone with an old PC tower kicking around their basement! All I find in the e-waste piles are laptops and LCD tvs. Maybe I should go to an antique shop or, *gulp* buy one.

I had some power adapters that I forgot to bring back when returned several cable boxes to the cable company several years ago. I use one to power my 4008.

I've been using cheap little Shurflow type pumps for a few years now.... and a cheap temperature control, to turn on at thaw and off at freeze... No valves or heaters, etc. etc.... and I just leave it out there. Have never had a pump freeze, that I'm aware of... I suppose there's a possibility that it starts up when froze and thaws itself out...
But bottom line.... It has been working just fine to leave it out. Haven't had to replace a pump yet.
