The premium water powered backup sump pump

“Ask for it by name”

Basepump® Water Powered Backup Sump Pump

How do I prevent basement flooding without using a battery? Is there a system that can run for a long period of time with no maintenance and no electricity?

The answer is a water powered backup sump pump that runs off the reliable water supply that brings water to your home under pressure every single day. The best answer is the Basepump Water Powered Backup Sump Pump.

  • Rain, power outages, flooded basements! Don’t wait until your basement is destroyed.
  • Rest easy knowing you have the best backup sump pump system on the market.
  • Basepump water powered backup sump pump is an essential component in your basement.
  • Five (5) Year Limited Warranty is Included!
  • Water Alarm Included! A 9 Volt battery-powered water alarm is included, to warn you of rising water. Using its own float sensor, that is mounted inside the sump, when high water lifts the float the alarm sounds off with an 85 dB alarm, likely to be heard almost anywhere in your home. This alarm is included with your purchase of any Basepump.
  • NEW!!! Optional upgrade: Proteus sump level alarm sounds off to be heard in the home, and it also sends you an email when the sensor is triggered by high water in your sump. Since it is plugged in to be able to operate, if the power goes out, it can also tell you that!! For only $99.00 we will substitute the new Proteus WiFi sump water level alarm for the standard model.
  • No Electricity, Battery, or Charger needed. Basepump needs none of these to operate.
  • Fully Automatic operation. You don’t need to be home to operate it.
  • Uses water pressure from your existing water supply to remove water from the sump.
  • Highest pumping rates in the industry.
  • Most reliable operating system on the market.
  • Heavy duty construction, made from corrosion resistant polypropylene. It’ll last a very long time.
  • Detailed installation instructions included; basic plumbing skills are required. (DIY? In many cases, yes.)
  • Low cost of operation (only the cost of the water during actual operation).
  • No moving parts to break and no maintenance required (Test it every 2-3 months).
  • This system is superior to the battery backup sump pump systems typically used.

Avoid a flooded and destroyed basement because of a sump pump failure. Install a Basepump water powered backup sump pump system before it happens. You’ll be glad you did.
