Yeah, thought of that and timed the cycling of the pump, it runs for 8-10 seconds every 2 - 2.5 minutes between when the basin fills back up in a fairly heavy rain, so even losing some because of startup I'd still be OK with that, it equates out to between 2-3 hours which is usually more than enough to invoke plan C or the power to come back.

It has saved me during power outages, sump pump failures, more than once.

Thank you - I saw those also and didn't rule them out, it wouldn't be too difficult to tie into the waterline nearby.

I'm gonna do just that, simulate a power outage and see what happens next time we get a decent rain.
My biggest worry is being out at a client site and not here to throw a transfer switch or fire up the generator when the power does go out. Looking for something automated. We got 3.5 inches in about 30 minutes last Sunday night, fared well but lost power for a couple hours and had a mess to clean up. Nothing squeegees fans and dehumidifiers couldn't take care of, but had we not been here the finished area would have been a wreck.
We got off lucky, lots of folks fared far worse.
Thank you all for the input, why I love this place.
