Dual Float Controller
This control box contains a piggyback switch that powers
the Basement Watchdog Dual Float. The Dual Float
Controller will activate the pump when either float is
lifted, and then shuts off automatically 10 seconds after
the float drops.
Operating the Pump in a Continuous Duty Application
The Basement Watchdog pumps are rated for continuous duty and may be used in
applications requiring continuous pumping including fountains, ponds, etc. For use in
any continuous duty application the pump should be plugged directly into the wall
outlet without the use of the controller. The outlet must be a single phase properly
grounded 3-prong receptacle, 115V, 60HZ. For continuous duty operation, the pump
must be submerged at least 3/4 of the depth of the pump at all times.
Maintenance Check List
Maintenance should be performed 1-2 times per year.
1. Remove all debris from the bottom of the pit.
2. Remove all debris floating in the water.
3. Remove all debris from the float switch cage.
4. Remove all debris around the air relief valve.
5. Fill the pit with water. Make sure pump turns on at the intended level.
6. While the pump is running, make sure pump is evacuating water at a good pace.
7. While the pump is running, make sure a stream of water is escaping from the air
relief valve. If not, clear the hole of any deposits or debris.
Backup Installation
When the power goes out, the
Basement Watchdog AC sump
pumps will not operate. For
protection during a power
outage, a Basement Watchdog
battery backup system can be
installed. There are three
systems with matching batteries
that will provide protection.
The illustration at right is an
example of a typical battery
backup installation.
