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.
— Family referral story
This homeowner already had two primary sump pumps and a water-powered backup pump. For extra peace of mind during outages and heavy storms, they added PUMP PARTNER as another layer of protection.
— Multi-layer basement protection story
After moving out and renting the home, this homeowner wanted a backup solution that would keep the basement protected even when tenants may not have time to monitor the sump pit during storms.
— Rental home protection story
For this homeowner, basement flooding was not just about water on the floor. With a boiler and HVAC equipment in the basement, PUMP PARTNER helped reduce the worry of costly damage during power outages.
— Basement equipment protection storyCompatibility & Runtime Estimator
Not sure whether your sump pump is a good match for PUMP PARTNER? Enter the voltage and rated current from your pump’s nameplate label, then add how often your pump runs and how long each cycle lasts to estimate backup runtime during a power outage.
For best performance, we recommend powering one primary 115V–120V residential sump pump with PUMP PARTNER.
You can usually find voltage and amps on the pump nameplate label.
