Spring 2026 Could Be One of the Worst Seasons for Basement Flooding

CINCINNATI, OH, DATE – Plumbing professionals across the United States and Canada are reporting a significant increase in sump pump service calls as 2026 gets underway. Roto-Rooter, North America’s largest plumbing and water cleanup provider, is experiencing a 32% surge in service requests compared to the same period last year. Last spring, call volume climbed 75% between March and April before reaching its peak in May, and early indicators suggest this year’s demand is already outpacing that trajectory. With above-average winter snowpack now melting across wide portions of the U.S. and Canada, and heavy rainfall events already making their presence felt with more forecast ahead, sump pumps are facing growing pressure heading into what may prove to be one of the most challenging spring seasons in recent years. Plumbing professionals are cautioning 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 and the recommended course of action for each.

“We have seen a significant influx of sump pump-related calls this season, not just from homeowners but from commercial clients as well. We have not hit the peak 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 is this saturated, a sump pump must be inspected. Without that step, it is essentially operating on borrowed time.”

The 5 Most Common Sump Pump Failure Points

1. Float switch failure – Representing the single most frequent point of failure, a faulty float switch can cause the pump to run without stopping or fail to activate when water levels rise. Owners should remove the sump pit cover and confirm the float is not tangled, pinned against the pit wall, or coated in debris. Manually lifting the float to verify pump activation is a useful first step. If the pump still fails to trigger or continues running after the float has been cleared, a licensed professional should replace the switch before spring conditions reach their peak.
2. Motor burnout – More often the result of smaller, overlooked issues than a sudden mechanical failure, motor burnout is among the most costly outcomes a property owner can face. Before drawing conclusions, owners should check the GFCI outlet and breaker box, as a nuisance trip is sometimes the only issue present. If the outlet is confirmed to have power and the pump remains completely unresponsive, the unit will require full replacement.
3. Worn or damaged impeller – A compromised impeller reduces pumping efficiency and places progressive strain on the motor over time. Owners should unplug the pump, remove it from the pit, and inspect the intake screen for debris. Flushing both the inlet and discharge openings with a garden hose can resolve minor blockages. If reduced performance or unusual noise continues after cleaning, the impeller is likely cracked or warped and will need to be professionally replaced.
4. Clogged or frozen discharge lines – Particularly common during early spring, a blocked discharge line causes water to back up into the pit with no outlet. The inspection should begin outside at the discharge outlet, checking for ice or debris. When freezing is the issue, a hair dryer or heat lamp can be used to thaw the line. Open flames should never be used under any circumstances. If the blockage extends deeper into the underground piping, a professional drain cleaning service will be required to fully restore flow.
5. Check valve failure – A failed check valve allows pumped water to drain back into the pit, forcing the pump into a continuous cycle that accelerates burnout. Owners should unplug the pump, position a bucket beneath the valve, remove it, and install a replacement, taking careful note of 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 cause vibration in surrounding walls, engaging a licensed plumber is strongly advised.

The Financial Stakes

A sump pump failure during peak spring conditions carries considerable financial consequences. Basement water damage restoration typically ranges between $5,000 and $25,000 depending on the extent of the damage, with just one inch of standing water capable of generating up to $25,000 in losses. Adding to the financial exposure, standard homeowner’s insurance policies generally do not cover groundwater intrusion or sump pump failure-related flooding, leaving most property owners without a safety net. In contrast, a professional pre-season inspection – widely considered the most cost-effective protective measure available – averages between $300 and $500 based on industry data.

“In 25 years of plumbing work, the springs that catch people most off guard are always the ones that follow the heaviest snow seasons. People watch the snow melting and assume the worst has passed – it has not. That water is actively moving and seeking the path of least resistance. Without a properly functioning sump pump, it will infiltrate the basement, saturate flooring, and damage everything stored in its path,” Jones said.
