The two deadly mistakes — get these right above everything else.

After helping many well-water families, I see the same handful of mistakes again and again — and every one is avoidable. This guide gathers them into one place, grouped by water, power, safety, and planning, with the honest fix for each. One of them is genuinely dangerous. Rather have a hand?

Common Well-Pump Backup Mistakes, at a Glance

Most well-water backup regret comes from a short list of avoidable mistakes. The water ones: no stored water, or trusting the pressure tank as a supply. The power ones: a 120-volt-only generator that can't start a 240-volt pump, or sizing to running watts instead of the startup surge. The safety ones — the deadly ones — backfeeding a cord into an outlet, or running a generator indoors; both can kill, and both have absolute fixes (a transfer switch by a licensed electrician; outdoors only). And the planning ones: never testing the setup, or forgetting the septic pump, animals, winter heat, and medical needs. Every mistake here has a simple, known fix — flip them over and you have a complete plan. There is a printable page-by-page version up top.

Common Questions

1 What is the most common well-pump backup mistake?

Having no stored water — relying on a generator or battery alone. The fix is cheap and simple: keep a few days of water in place before any outage, as the layer under everything else.

2 What is the most dangerous mistake?

Backfeeding — running a cord into an outlet to power the home or pump. It can electrocute you or a lineman. Always use a transfer switch or interlock installed by a licensed electrician.

3 Why won't my generator start my well pump?

Usually because it is 120-volt only or short on startup surge. Most well pumps need 240 volts and a big surge. Check both against your pump's numbers before buying.

4 What loads do people forget to plan for?

The septic pump, the furnace blower in winter (gas furnaces still need power), livestock water, and medical or senior needs. A complete plan walks through the whole home.

5 Why is testing so important?

A setup you've never run is a question mark. Test it on a calm day so you don't discover a problem in the dark during a storm — it costs nothing but an hour.

6 I have an old setup — how do I check it?

Start with safety: confirm the hookup is a real transfer switch or interlock, not a backfeed arrangement — a licensed electrician can verify. Then check water, power, and testing.
