How Basepump Works

  • When water rises above the normal high water level in your sump pit, for any reason, the Basepump float lifts.
  • The float then opens a valve, sending municipal water through the Basepump Ejector.
  • This water flow creates powerful suction, which draws sump water up from your pit and discharges it outdoors.
  • Once the float returns to its normal level, a pre-set timing control keeps Basepump pumping long enough to completely drain the sump before switching off.
  • This cycle repeats when the water level rises above normal again.
  • More on how Basepump works.


  • The Basepump water pressure sump pump is mounted on the ceiling, high above the sump pit, so that it does not have to fight downward water pressure. As a result, it delivers dependable pumping power without undue strain on the pump.
  • Ceiling mount also keeps the pump safely away from the corrosion, clogging, debris, and scale build-up that can take place in the sump pit.
  • Pump has no mechanical parts, motors, or turbines to break. No maintenance required.
  • Heavy duty, corrosion resistant polypropylene construction.
  • Float is hydraulic for added reliability, and has no electronic components to worry about.
  • No battery, wires, or charger needed to run the pump.
  • Check valve prevents water from reversing and flowing back down into the sump.
  • 5 year limited manufacturer's warranty, the industry's longest.
  • Each unit is hand-assembled and hand-tested in the USA.


  • Fully automatic operation. Starts pumping when needed, whether you are home or away. Completely independent of your main pump.
  • Float positioning and cycle timing control are both adjustable, to ensure sump is emptied completely on each cycle.
  • Unlimited running time, as long as water supply is available.
  • Low cost to operate. No cost until it runs; then only cost is the water.
  • More efficient water use than other water powered pumps on the market: 1 gallon of municipal water removes 2 gallons of sump water, at 10' of lift and 90 lbs. PSI.
  • Independent water alarm included (a $30 value) to alert you to high water conditions. Can be connected to your security system.
  • Can be installed safely in radon-sealed sump pits.
  • Works in small sump pits, as small as 10" diameter.

Water Supply Checklist

To make sure you can use the Basepump HB1000 water pressure sump pump, verify the following:

  • Household Water Pressure: You need between 40 and 90 PSI at the Basepump Ejector. Avoid excessive piping from the tee-in point (see the diagram above of the Basepump connection to your water line).
  • Household Water Flow: To use the Basepump HB1000 pump, you need to be able to fill a 5 gallon bucket within 30 seconds with water from your home's hose spigot.
  • Pipe Types: Basepump requires full-flow copper piping or an equivalent (PVC, CPVC, PEX are all fine as long as they are approved in your area). Basepump CANNOT be used with galvanized iron pipes.
  • Pipeline Restrictions. Basepump needs to be teed into your water line before any devices that can restrict water flow. Examples of these devices include: stop & waste valves, pressure regulator valves (PRV), water conditioners, water filters, etc. Water meter must be minimum 3/4" standard.
