32% Surge in Sump Pump Calls Signals a Dangerous Spring Season

Plumbing professionals across the United States and Canada are reporting a significant spike in sump pump service calls as 2026 gets underway. Roto-Rooter, North America's largest plumbing and water cleanup provider, is tracking a 32% increase in calls compared to the same period the prior year. During the previous spring, call volume climbed 75% between March and April before reaching its highest point in May, and current data indicates this year's trajectory is already running ahead of that pace. With above-average winter snowpack melting across wide stretches of the U.S. and Canada, and heavy rainfall already making its presence felt with more storms forecast ahead, sump pumps are facing mounting pressure heading into what could be one of the most demanding spring seasons in recent history. Plumbing professionals are cautioning homeowners and businesses alike that the window for preventive maintenance is closing fast, as demand is expected to intensify through April and May.

To help property owners get ahead of potential problems, Roto-Rooter's team of plumbing experts has identified the five most common sump pump failure points along with clear guidance on how to address each one.

"There has been a noticeable influx of sump pump-related calls this season, coming from both homeowners and commercial clients. The peak has not arrived yet, and that is always a telling indicator of what lies ahead," said Dave Jones, Master Plumber and VP at Roto-Rooter. "When the ground reaches this level of saturation, a sump pump that has not been inspected is essentially operating on borrowed time."

The 5 Most Common Sump Pump Failure Points

1. Float switch failure - The leading cause of sump pump failure, this issue can cause the pump to run without stopping or prevent it from activating at all. Property owners are advised to remove the sump pit cover, verify that the float is not tangled, pressed against the wall, or coated in debris buildup, and manually lift it to confirm the pump responds. If the pump still fails to trigger or continues running after the float is cleared, a professional should replace the switch before spring conditions reach their peak.
2. Motor burnout - More often the cumulative result of smaller, unaddressed issues than a sudden failure, motor burnout ranks among the most costly outcomes a sump pump owner can face. Before drawing conclusions, owners should inspect their GFCI outlet and breaker box, since a nuisance trip is sometimes the only underlying problem. If the outlet is confirmed to have power and the pump remains fully unresponsive, the unit will require replacement.
3. Worn or damaged impeller - A compromised impeller gradually reduces pumping efficiency while placing increasing strain on the motor over time. Owners should unplug the pump, remove it from the pit, and inspect the intake screen for accumulated debris. Flushing the inlet and discharge openings with a garden hose can resolve minor blockages. If noise or diminished performance continues after cleaning, the impeller is likely cracked or warped and will need to be replaced by a professional.
4. Clogged or frozen discharge lines - Particularly common in early spring, this failure causes water to back up into the pit with nowhere to go. The recommended first step is to check the exterior discharge outlet for ice or debris. If the line is frozen, a hair dryer or heat lamp can be used to thaw it safely. Open flames should never be used under any circumstances. If the obstruction is located deeper within the underground piping, a professional drain cleaning service will be required to fully clear the line.
5. Check valve failure - When the check valve fails, pumped water flows directly back into the pit, forcing the sump pump into a relentless cycle that rapidly accelerates burnout. Owners should unplug the pump, position a bucket beneath the valve, remove it, and install a replacement while paying close attention to the directional arrow on the valve body, which must point upward and away from the pump. If the pipe configuration requires cutting PVC or the backflow is strong enough to produce vibration in surrounding walls, engaging a licensed plumber is strongly recommended.

The Financial Stakes

A sump pump failure during peak spring conditions carries serious financial consequences. Basement water damage restoration typically averages between $5,000 and $25,000 depending on the severity of the event, with as little as one inch of standing water capable of producing up to $25,000 in property damage. Adding to the financial exposure, standard homeowner's insurance policies generally do not cover groundwater intrusion or flooding caused by sump pump failure, leaving most property owners to absorb the full cost out of pocket. In contrast, a professional pre-season inspection - widely regarded by industry professionals as the most cost-effective step an owner can take - typically ranges from $300 to $500.

"In 25 years of plumbing, the springs that catch people completely off guard are always the ones that follow the heaviest snow seasons. Homeowners see the snow beginning to melt and assume the worst has passed - it has not. That water is actively moving through the ground, and it is searching for the path of least resistance. Without a fully operational sump pump in place, it will find its way into the basement, saturate flooring and carpeting, and damage whatever is stored below," Jones said.
