Basement flooding affects hundreds of thousands of U.S. homes each year. Power outages, sump pump failures, and heavy rain can leave basements vulnerable when the pump stops running.
A single basement water event can cost thousands of dollars in cleanup, flooring, drywall, furniture, electrical work, and lost personal property.
Water damage claims may lead to higher homeowners insurance premiums, depending on your insurer, claim history, location, and type of loss.
Figures are general industry estimates. Actual damage, claim impact, insurance changes, and basement flooding risk vary by home, location, insurer, policy, and event severity.
Automatic Switchover Demo
Unplug the power. PUMP PARTNER automatically switches to battery output and keeps your sump pump running — helping protect your basement when the grid goes down.
Utility power goes out
PUMP PARTNER detects the outage
Your primary sump pump keeps running
This demo uses a Zoeller M53 sump pump — a popular residential model rated at 115V and 9.7A — to show the same automatic switchover logic used during a real sump pump power outage.
Buy With Confidence
Use your pump’s voltage and rated current to check whether it is a good match for PUMP PARTNER, estimate backup runtime, and order automatic backup power before the next outage.
You can usually find voltage and amps on the pump nameplate label.

After reviewing the installation, the homeowner’s electrician understood why automatic backup power for a primary 120V sump pump is different from a basic portable power setup. The plug-and-play design made the solution easy to understand and trust.
— Homeowner installation story
After using the first PUMP PARTNER, this homeowner felt confident moving forward with finishing the basement. Since the home also had a second sump pit, they later added another unit for added protection.
— Homeowner with a dual-pit basement
This customer first saw PUMP PARTNER installed at a parent’s home and watched it stay ready through the seasons. After seeing the setup work in real life, they decided to add one for their own basement too.

Questions Before You Buy
Clear answers about setup, compatibility, runtime, safety, and everyday use.
Yes. PUMP PARTNER is designed for 24/7 standby use. When utility power is available, your sump pump runs normally through the unit. When power fails, PUMP PARTNER automatically switches to battery output and keeps the pump running.
For best performance, we recommend powering one primary sump pump with one PUMP PARTNER unit. Two pumps starting at the same time may create a high surge load and could trigger overload protection.
During a power outage, PUMP PARTNER automatically switches to battery output. The screen and indicator lights help show the unit’s operating status, battery level, and output condition.
Yes. During an outage, PUMP PARTNER powers your sump pump from the battery. Battery level will decrease depending on pump wattage, how often the pump runs, and how long each cycle lasts.
Overload protection helps protect the unit and connected equipment when the pump draws too much power. This can happen if two pumps start together, the pump is aging, the impeller is blocked, or the discharge line is restricted.
If you need to store the unit or disconnect it for a long time, unplug the AC charging cord first, then power off the unit manually. PUMP PARTNER is designed to stay connected during normal standby use.
Runtime depends on your pump’s wattage, cycle frequency, and run time per cycle. Many residential sump pumps run intermittently, so actual backup time can vary widely. Use the compatibility and runtime estimator on this page for a practical estimate.
No. PUMP PARTNER is plug-and-play. Plug your sump pump into PUMP PARTNER, then plug PUMP PARTNER into a standard wall outlet. No plumbing changes or rewiring are required for typical residential use.
PUMP PARTNER uses a maintenance-free LiFePO₄ battery system. For normal use, keep it plugged in and ready. If storing it long-term, fully charge the unit and recharge it periodically.
Most portable power stations are designed for general appliances or temporary use. PUMP PARTNER is designed specifically for standby sump pump protection, automatic switchover, and always-ready operation with a primary 115V–120V residential sump pump.
PUMP PARTNER is built for indoor residential standby use and is designed to operate near a sump pump area. It should be kept indoors, dry, and away from standing water or direct water exposure.
New PUMP PARTNER units include a 36-month warranty for customers in the contiguous United States. If you have a support question, you can contact us at service@pumppartner.us.
