Repeated stopping and starting can definitely hurt you, I'd recommend using a 2 float system to establish a zone of control rather than a single float which can cause a motor to chatter.
    I'll take your word for it since 99% of what you said sailed straight over my head.

    The backup pumps are still rated for several hundred to a couple thousand gph. I would expect it to keep up just fine.

    Something like this setup.

    Welp. On closer inspection she seems to have a good quality 1/3rd hp pump. 1 1/4 drain lines seem small to me, but what do I know.
    Then I notice what the pump is sitting in.. a half buried (and I mean barely half) drywall bucket. Maybe fills up with 2 whole gallons of water before triggering the float.
    Oh, and there's no check valve. So the bucket half refills as soon as the pump turns off.

    Fricken genius!

    If it has worked up til now...

    When was the last time we had a flood and power outage at the same time? Back up systems, especially battery based ones seem like wasted money to me.

    Whut?

    That is when we lose power. We don't lose power when it's sunny, 85, and convenient.


    As to "if it works". We have no idea how well or poorly it works. Home is new to her, this is her first spring here. She was pretty upset when she sent me video of the wall "peeing" water into the middle of the room! On 2nd look it doesn't seem quite as bad as the text message indicated. But.. well.. you know.

    My spidey senses tell me that the pump cycles too much. My limited understanding of such things is that many pump cycles => sad pump. Fewer => happier pump. I think I can add a check valve and drop in a larger diameter sump bucket. I think those two upgrades should improve the situation a bunch.

    Mine has been cycling every 10-15 minutes pretty much all week.

    Check valve will be a huge improvement since you won't be dumping half a gallon back into the bucket when the pump shuts off.

    Also, FWIW, my pump moves about 2gal when the float is tripped. Sounds to me like her setup is reasonable with the exception of the check valve.

    I believe a backup system would fall under the category of "I'd rather have it and not need it than need it and not have it".

    Looks like the 12VDC backup pump systems run about $500 all in. Advertising about 10-12 hours of continuous use.. or 24+ if cycling. That seems pretty reasonable to me.

    Although at this point she's telling me she'll just not put anything on the floor in the basement and cross her fingers.
    What about putting a UPS on a stand? You should be able to get her a good deal on one.

    I wanted a UPS to run our Rinnai wall heater during a power outage: it's only about 120 for the fan and igniter. Probably a dozen people said, "You can't do that." Than I learned that Rinnai sells one for just that purpose. We got a whole house genset so didn't need it.

    A friend of mine rigged a boat bilge pump to two batteries as a backup: it's in the same well, a few inches higher than their main pump. But while their ratings sound impressive, low voltage, head height, and flow resistance give most installations only about half their rated capacity. But they're cheap: less than $100.

    You would think I'd be able to score great discounts on UPSes.. but it seems maybe not. Turns out a few of my coworkers have "decommissioned" environmental monitoring hardware in their basements too.. including leak detection rope sensors. Neat stuff.

    In the end it turns out her basement just isn't as bad as I/we thought. The french drains are effective. I unplugged the sump for an hour or two and it filled, but did not flood. I'm feeling this may just be a nuisance we live with.

    A standby generator would be the nuke from orbit approach. Would be nice.
