Quick Summary

  • High-performance battery back-up sump pump
  • Easy, do-it-yourself installation.
  • Average pumping rate: 900 gallons/hour, at 9 feet of lift
  • Corrosion resistant components
  • Advanced finish-charger protects battery
  • Water alarm alerts you to high water conditions
  • Free Shipping to the continental USA

Unique Features

  • Easy to install. Stainless steel mounting bracket makes it easy to position the pump. All connections are made above the floor. No re-working of main sump pump piping. Usually takes about an hour.
  • Durable construction – The DH900 is made from high grade components. Each unit is hand-assembled and hand-tested in the USA.
  • Better charger - High quality finish charger protects you from ending up with an overcharged, dead battery.
  • Pump stays dry - Hangs on its bracket above the normal water line, extending its life.
  • Check valve protected - Many back-up pumps' check valves are placed close to the primary pump's exit. The high water turbulence at this point can damage the check valve, potentially causing a basement flood. The DH900 avoids this problem by connecting to the discharge pipe 3 to 4 feet above the main pump's exit. This allows you to install the check valve at a safe point where water is running smoothly through the pipe, preventing damage to the check valve.

Pump Capacity

  • Pumping rates: 900 GPH at 9' of lift, 1300 GPH at 5' of lift
  • Provides 12 hours of pumping time if pump cycles every minute, 48 hours of pumping time if pump cycles every 5 minutes, and 96 hours of pumping time if pump cycles every 15 minutes
  • Each pump cycle above represents 30 seconds of pumping time
  • Pumping time can be doubled by adding capacity for a second battery with optional Dual Battery Case.

Installation

  • Stainless steel mounting bracket included, making installation simple and easy. Usually takes about an hour.
  • Everything needed for installation is included, except the battery and a few basic supplies (see Hydropump installation instructions and necessary installation tools below)
  • Hydropump is independent of your main sump pump, which means you do not have to rework the main pump or pipework

Operation

  • Heavy duty, efficient motor allows for long life and running time
  • Water alarm sounds when backup pump is operating, alerting you to high water conditions

Battery

  • High-impact plastic battery case protects the battery and terminals, while allowing plenty of ventilation.
  • Double your pumping time by adding capacity for a second battery with optional Dual Battery Case
  • Note: Battery NOT included, due to shipping weight. Recommend buying a 12 volt battery at a hardware or automotive store. Any of the following types work: Marine Deep Cycle, Sealed Lead-Acid, Gel Type or AGM. Use case size 27. More information on sump pump batteries.

Charger

  • High quality finish charger included. Can charge 2 batteries, if using optional Dual Battery Case
  • Battery status light indicates whether battery is good or needs replacement.

What is "lift?"

  • "Lift" is the height the sump water must be pumped before leaving the house.
  • A typical basement is 7 feet tall, plus 2 feet into the sump pit, for a total of 9 feet of lift. Higher lift distance makes the pump work harder, thereby reducing its pumping rate.
