The Basement Sentry I and Aquanot 508 12 volt DC pumps are sold just as the back-up pump. The primary pumps are sold separately so you can add this back up pump system to your existing sump pump. The Basement Series 12 volt DC pumps are designed for emergency backup use in clear water sump pumps when the primary AC powered pump or pumps fail to turn on. Primary pumps can fail due to power outages during storms or brownouts, or because of wiring and electrical problems, mechanical malfunction or obstructions in the pit. The 12 volt DC pump will turn on if the primary pump fails to turn on or is unable to keep up with excessive water due to rain or other conditions that can cause your basement water removal system to overload. Both the Basement Sentry I (model 507) and the Basement Aquanot 508 (model 508) have the same basic functions. The only difference is the size and performance of the pump. If more than 7 hours continuous run time will be required then two or more batteries should be connected in parallel to extend the run time hours. Both the Basement Sentry I and the Aquanot 508 can be used with multiple batteries but an extra battery case with a hookup wire (P/N 007861) must be ordered separately for each additional battery to be used.
What the Basement Sentry I and the Basement Aquanot 508 have in common:
DC CONTROLLER / Charger: Self contained 10 amp battery recharger includes battery burn out and overcharge protection. The solid state automatic control has alarms, light indicators and warning systems. Keeps the battery ready for use and recharges the battery after it's used and the AC power is restored. If the battery does not charge properly the LCD will display BATFAIL and sound an alarm buzzer. The charger is super efficient and complies with the California Battery Council standards.
LCD SCREEN: Constantly displays battery voltage and will display other helpful information about the system, such as DC pump cycles and power outages, by simply touching the scroll button.
AC Power LED LIGHTS:
- Red = AC Power supply "on"
- Red Blinking = AC Power supply "off"
- Yellow = Battery "charging"
- Green = Battery "fully charged"
- Low Battery LED Light = Red low battery light blinks when battery is below 10.8 volts, rapidly blinks when below 8.4 volts
- Pump Cycled LED Light = Yellow light will blink when float activated, becomes solid after 3 seconds
- Alarm Off Light = Yellow light indicates the buzzer is silenced
ALARMS: Continuous steady buzzer sounds for "low battery". Alarm also sounds for High Water or Reverse Polarity detected.
FLOAT SWITCH: Low voltage, reliable, vertical.
BATTERY CASE: The included battery case will accommodate maximum battery dimensions of 13"L x 7-1/2"W x 9-1/2"H and fits all group size 27 marine batteries. Made from non corrosive polyethylene. Contains lock strap.
BATTERY: Not included. However, the estimated life of a fully charged (175 minute reserve capacity) battery when the pump is operating continuously is approximately 7-1/2 hours.
FITTINGS: All parts required for installation and mounting are included for each system including brackets, wall anchors, PVC fittings, and cable ties. PVC pipe must be provided by the installer.
PIT SIZE minimum requirements: 18" diameter x 24" deep.
The pumps are the only difference!
The Model 507 will pump 900 GPH (15 GPM) at 10 ft. head. Not recommended for installations over 15 ft. total dynamic head. This pump outlet has 1-1/2" PVC spigot adapter built-in to glue directly into a 1-1/2" Tee provided by the manufacturer.

The Aquanot Model 508 has a slightly larger pump that will pump 1800 GPH (30 GPM) at 10 ft. head. Not recommended for installations over 20 ft. total dynamic head. This pump outlet has 1-1/2" PVC slip adapter to glue directly onto 1-1/2" pipe.
