Backing Up the Well Pump, Furnace, and Sump Pump Automatically
Last verified: September 2026
Water, heat, and a dry basement are the loads that matter most — and an automatic system keeps all three going by itself. Here's how. On a well? My number is (330) 200-8042.
Backing Up the Essentials, at a Glance
Of everything an outage threatens, three loads matter most: water, heat, and a dry basement. An automatic system keeps your well pump, furnace, and sump pump running by itself. The well pump needs a big jolt to start — often several times its running power — so it shapes the whole system; even a gas furnace needs electricity; and the sump pump is the most-forgotten, most-regretted omission. There's a printable 29-page version up top.
Common Questions
1 Can an automatic system run my well pump?
Yes — a properly sized system starts and runs a 240-volt well pump automatically. The pump's big starting surge shapes the sizing, and load management can help a smaller generator handle it.
2 Will my gas furnace work in an outage?
Only if it's backed up. A gas furnace still needs electricity for its blower and controls — no power, no heat. Put it on your list to stay warm and keep pipes from freezing.
3 Why is the sump pump so important to include?
Because outages and heavy rain arrive together. Without backup, a storm can flood your basement while the generator runs everything else. It's the most-forgotten, most-regretted omission.
4 Do I need the biggest generator for the well pump?
Not necessarily — load management can let a smaller generator handle the pump's surge by keeping other big loads from starting at the same instant. Ask your electrician to size it both ways.
5 Should I add a battery-backup sump pump too?
For a real flooding risk, yes — it's an affordable second layer that covers even the brief transfer gap, so a dry basement never depends on one system.
6 What should I tell my electrician first?
That you're on a well, if you are — the pump shapes the whole system. Then make sure the furnace and sump pump are on your list and prioritized.
Would You Rather I Just Help?
Water, heat, and a dry basement are the loads that make backup power truly worth it, and planning around them — especially a well pump — is exactly what I love to help with. $99 flat for a visit, 30-day come-back-free.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
