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? I've contacted the pump manufacturer
about this but haven't heard back yet.

Thanks

Rather than the washer fluid, I'd consider using RV antifreeze. According
to this web site, it would be safe for your pump.
