“A Smart Investment for Single Homeowners”
The Pump Partner has exceeded all my expectations. I’ve had several power outages since we installed it, and each time, the system kicked in flawlessly. One incident, in particular, stands out. It was the middle of the night during a severe storm, and the power went out for several hours. Normally, this would have sent me into a panic, scrambling to start the generator and praying the sump pump would keep up. But with the Pump Partner, I didn’t have to lift a finger. The system automatically took over, and my basement stayed dry. When the power finally came back on, the Pump Partner seamlessly transitioned back to normal operation without any issues.
“A Reliable Safeguard for Our Home”
One of the things that impressed me the most about Pump Partner is its rock-solid reliability. We’ve had our fair share of power outages, especially during the stormy seasons, and each time, Pump Partner has kicked in without a hitch. Knowing that the system will automatically take over and keep our sump pump running gives me immense peace of mind. I don’t have to worry about rushing to the basement during a storm or waking up in the middle of the night to start a backup generator. It just works—every single time.This kind of stability is priceless in a busy household where there’s always something that needs attention. Pump Partner takes one major concern off my plate, allowing me to focus on what’s most important: my family.
Consistent Performance, Low Maintenance
After retiring, the last thing I wanted was to spend my time dealing with home maintenance issues, especially something as critical as a sump pump during a power outage. Pump Partner has been a fantastic addition to our home. It’s reliable, maintenance-free, and does exactly what it’s supposed to do. We’ve had a few power outages since we got it, and every time, it has worked perfectly without any intervention needed. It’s one less thing to worry about in retirement, and I highly recommend it to anyone who wants a dependable solution.
Protects My Home and My Clients’ Homes
In my line of work, I know how important it is to have a well-protected home, especially when it comes to preventing water damage. That’s why I chose Pump Partner for my own home and why I recommend it to my clients. It’s not just about keeping the basement dry—it’s about safeguarding your entire investment. The system is easy to explain to clients, and they love the idea of a hands-off, reliable solution that keeps their homes safe during power outages. It’s become a key selling point for properties in areas prone to heavy rain.

Before moving from Wisconsin to Washington, a Milwaukee homeowner looked for a safer, more reliable way to protect a rental property’s basement. After questioning PUMP PARTNER’s conservative advice and confirming it with an electrician, a real summer storm and power outage put the system to the test — and the basement stayed just as dry as usual. A simple story about trust, electrical safety, and why responsible design matters more than bigger numbers.
PUMP PARTNER's recent half-page ad in The Montgomery News warns of an unusually intense hurricane season in 2025 and urges early flood preparedness. CEO David compares proactive sump pump backup planning to getting a flu shot before winter. The campaign has sparked strong community response across Montgomery, Hillsborough, and Princeton.
Using a typical portable power station as an automatic sump pump backup is not safe unless someone is physically present to monitor and restart it every 30 minutes. This completely defeats the purpose of a backup system during storms, especially at night or when you're away from home.
