I'm using a small pond pump (L G Sourcing Model MD 170) to operate a
contraption I built to open and close a small sliding wooden door on a
chicken coop on a timer. It pumps water into a jug that has a slow leak
so the door stays open while the pump runs all day (jug stays full),
and then at night (pump off) the water leaves the jug and the door
closes. Worked like a charm since June when I made it, but now that
cold weather is approaching, I need to modify the system. Here's my
question: Does anyone know whether or not this (or any pond pump) will
be damaged if I substitute windshield washer fluid (methanol based) for
the water?

Thanks

========================
The best people to answer that question would be the people who manufactured
the pump in question. I would think the chemicals in the windshield washer
fluid may attack any of the pumps seals they come in contact with.

Right, and thanks. I've contacted the company but haven't heard
anything yet.

How much water is in this system? If it's something fairly small, consider
insulating the jug, and using a small aquarium heater. A 50 watt heater will
use 36 kilowatt-hours a month. assuming you run it all day long, and will
keep 15 gal warm enough to prevent freezing. Just set the heater to the
lowest setting it can be set at, you don't need to keep it warm, just keep
it from freezing.

Thanks. Great idea. Might work.

Well I use various brands of pumps for ponds to pump coolant for my
machine tools and have yet to have a problem, and some of the coolants
I use are much stronger than methanol based fluids........Just use a
mag type pump, so there are no seals involved and I do belive you'll
be all right. I also use a water soluable oil with alchohol added
during extremely colder weather here and its been pumping for over 5
years now............I will say methanol has different reasctions with
some materials than say a petro based product would, but I seriously
doubt windshield washer antifreeze is going to do your pump in.

I doubt highly that the company is gonna giv eyou an answer other
than.....Our pumps are made for use in fresh water in a ponding
environment. Odds are they never tested them in antifreeze or any
other solutioin as it was not what they had in mind when they designed
and made the pump........so they will give a blanket statement as to
its intended uses.......if you ever get a reply.

You run a pump all day just to hold the door
open?!?!?!?

There's gotta be a better way....

Could you go with a light-activated switch to trigger the door operation
at the change of light...like a deer feeder?
