Sump pumps are one of the most boring parts of home ownership. Until that one storm comes and suddenly they’re interesting.
After losing power one time this summer, I got paranoid and decided to build a battery backup. Home Depot had the basement watchdog systems, but they seemed high maintenance and I wanted something that would let me be lazier. I went with a LifePo4 battery system, that will (hopefully) get me 10 to 15 years. The battery charger has a float/storage mode so it can stay on 24/7. Doing some test runs, I think I can get about 400 cycles out of the battery before it hits 0%. I added some additional safety features (DC circuit breaker, GFCI with auto-on, Lithium fire extinguiser, etc), and added some battery powered lights and a basket of hand tools, so in the event the power goes out in the dead of night, something goes wrong, and I have to get my feet wet, everything is there ready to go.
Or ya know, a siphon jet back up. Maybe not an option if you are on a well pump. But a much cleaner fix for power failure AND main pump failure. Its a good thing you can maintain the pumps yourself because ain’t nobody gonna touch that.
I mentioned in another comment but I have two pumps and an alternator that swaps between them, so I’m not overtly concerned with pump failure, more-so power failure.
The siphon’s are dope but yes wasn’t an option. I was a professional plumber in a previous life, so yea, I’ll be maintain this thing lol.
This is the first time I’ve heard of siphon jet backup pumps. That looks like a really great option and I wish I had known about those years ago when I put in my own battery backup.
