Average sump pump lifespan — and pumps tend to fail during the very storm they are working hardest in. Plumbers recommend proactive replacement at that age.

SEASON PASSED292 days until spring thaw test (last 32°F)Apr 29
In Newark the spring thaw peaks around the last 32°F freeze, near April 29 (1991–2020 normals) — a good twice-a-year cue, with the fall rains, to pour five gallons in the pit and watch the pump run. The early-odds date runs roughly 14 days ahead of the median, so build in that buffer.

- The first freeze in Newark lands in mid-fall, a comfortable but not open-ended window.
Newark draws its numbers from Newark Wtr Wks, 835 feet up and 2.1 miles away. Its median first-freeze dates are 32°F by Oct 16, 28°F by Oct 27, 24°F by Nov 7. Year to year the 28°F date has ranged from Oct 13 to Nov 9 — about 27 days apart. Spring's last 32°F freeze clears around Apr 29. Snowfall averages 15 inches a year, first reaching an inch near December.
In Newark, freezing nights (32°F) typically begin around Oct 16 and the first hard freeze (28°F) follows near Oct 27. The 32°F date swings from Oct 1 at its earliest to Oct 28 at its latest, near 27 days. The last spring freeze averages Apr 29 and as late as May 17, which sets the safe window for reopening outdoor water and de-winterizing gear. About 15 inches of snow a year is enough to justify servicing the snow blower and watching the eaves.
Your sump pump checklist
- Pour about five gallons of water into the pit slowly and watch the float rise, the pump start, and the water drop.Helpful gear: Water level alarm — Recommended pick
- Confirm the discharge line carries water 10–20 feet from the foundation and does not drain back into the pit.Helpful gear: Sump check valve — Recommended pick
- Clear the inlet screen and the pit of gravel and debris that can jam the float or the impeller.
- Check the check valve for a firm click; a failed valve lets discharged water fall back and short-cycle the pump.
- Add a battery backup pump so the system still runs when a storm knocks out the power.Helpful gear: Battery backup sump pump — Recommended pick
- Test the backup on battery power and note the install date; batteries usually need replacing every few years.
- If the primary pump is 7–10 years old, keep a replacement on the shelf before it fails mid-storm.Helpful gear: Replacement primary pump — Recommended pick
- Remember that flood insurance and most homeowner policies treat pump failure separately — read your coverage.

Damage a single inch of water in a home can cause, per FEMA — and standard homeowners policies exclude flood damage; sump failure usually needs a separate endorsement.
FEMA / FloodSmartThe bucket test: pour water slowly into the pit — the float should rise freely, the pump should kick on within seconds, empty the pit and shut off. Test at least twice a year.

AngiWhat this means locally
Newark freezes later than Lancaster (Apr 22) and later than Westerville (Apr 22) — a reminder that even nearby towns differ by days. Statewide, Ohio prep dates run Apr 8 through May 8, which is why Newark gets its own number rather than a Ohio-wide average. The same freeze also decides when to protect your pipes and watch your roof. Keeping an eye on the rest of the county? The same local math is on our Middletown and Parma pages.

Frequently asked questions
How do I test my sump pump before heavy rain?
Pour about five gallons of water into the pit slowly and watch the float rise, the pump switch on, and the water level drop. Confirm the discharge carries water well away from the foundation. Doing this before the wet season, and again in spring near the last freeze around Apr 29, catches problems early.
How often should a sump pump run?
It varies with your water table and weather; some pumps cycle every few minutes during a storm and sit idle for weeks in dry spells. Frequent cycling with no rain can signal a stuck float, a failed check valve, or groundwater seeping in. Occasional running during wet weather is normal.
How long do sump pumps last?
A typical sump pump lasts about 7 to 10 years, though hard-working pumps wear out sooner. If yours is near that age, keep a replacement on hand so a mid-storm failure does not leave the pit unattended. Testing it seasonally tells you more than age alone.
Do I need a battery backup sump pump?
If your basement floods when the power goes out, yes — storms that overwhelm the pit are exactly when the grid tends to fail. A battery backup runs the pump through an outage, which is the single most common cause of a wet basement during heavy weather. Test the backup on battery power, too.
Does insurance cover sump pump failure?
Standard homeowner policies and federal flood insurance often exclude damage from a sump pump that fails or is overwhelmed. A separate water-backup or sump-failure rider may be available. Read your policy before a storm, because assumptions about coverage are a common and costly surprise.
Why is my sump pump running with no rain?
A high water table, snowmelt, or groundwater seepage can keep the pit filling even in dry weather. A pump that runs constantly may also have a stuck float switch or a check valve that lets discharged water fall back into the pit. Check the float and the valve first.
How often should I test my sump pump?
At least twice a year — before spring thaw and before fall storm season — and monthly during heavy-use months if the basement is finished. Pour a 5-gallon bucket of water slowly into the pit and confirm the pump starts within seconds, empties the pit, and shuts off on its own. Idle float switches commonly stick against the pit wall, and a water test is the only way to catch that early.
