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.
Family HandymanWhen to Test Your Sump Pump in Lehi, UT
SEASON PASSED293 days until spring thaw test (last 32°F)Apr 30
Two moments stress a Lehi sump pump: the spring thaw near April 30 and the fall rainy season, so test before each with a five-gallon bucket in the pit. The early-to-late range spans roughly 32 days, so treat the median as a midpoint, not a promise.

- Lehi sits in the middle of the pack, with a mid-fall first freeze — don't let a mild stretch push the work later.
Numbers for Lehi come from Utah Lake Lehi, 3.3 miles away at 4,505 feet, where the medians fall 32°F by Oct 9, 28°F by Oct 22, 24°F by Nov 2. Year to year the 28°F date has ranged from Oct 5 to Nov 6 — about 32 days apart. Spring's last 32°F freeze clears around Apr 30. Snowfall averages 26 inches a year, first reaching an inch near November.
In Lehi, freezing nights (32°F) typically begin around Oct 9 and the first hard freeze (28°F) follows near Oct 22. The 32°F date swings from Sep 26 at its earliest to Oct 25 at its latest, near 29 days. The last spring freeze averages Apr 30 and as late as May 27, which sets the safe window for reopening outdoor water and de-winterizing gear. About 26 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.

AngiWhat this means locally
Against its neighbors, Lehi (first freeze Apr 30) runs later than Draper (Apr 18) and later than Riverton (Apr 18). Across Utah, local prep deadlines in our data range from Mar 14 to May 8, so a statewide rule of thumb would miss Lehi by weeks. In Lehi, that same cold is your cue to protect your pipes and watch your roof. Keeping an eye on the rest of the county? The same local math is on our Layton and Logan 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 30, 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.
