Sump Pump Backup Power Made Simple
How PUMP PARTNER Keeps Your Sump Pump Running During a Power Outage
Plug your existing 115V–120V primary sump pump into PUMP PARTNER. When utility power fails, it automatically switches to battery backup and keeps the pump running.
How It Works

No rewiring. No plumbing changes. No complicated setup.
Plug It In
Connect your existing primary sump pump to PUMP PARTNER.
Stays on Standby
When grid power is available, your pump runs normally from wall power.

Why It Is Different
Not Just a Portable Power Station
Sump pumps do not run like normal appliances. They may sit idle, then suddenly start when water rises. PUMP PARTNER is designed for this storm and outage use case.
Compatibility & Runtime
Will It Work With My Pump?
PUMP PARTNER is designed for most standard 115V–120V residential primary sump pumps. Enter your pump’s voltage, rated current, and cycle pattern to estimate compatibility and backup runtime.
