PondBuilder™ PUMP INFORMATION
PondBuilder™ products are created by experienced pond professionals. ese multi-purpose submersible
pumps are designed for use in water garden and koi pond ltration systems, and to create waterfalls, streams
and water features.
Mag-Drive models are suitable for pumping clear ltered water, such as when using a PondBuilder™
Pond Skimmer or when placed inside a pump sock. e temperature of the water being pumped must
never exceed 95 degrees Fahrenheit. Do not pump sewage, inammable, corrosive or explosive liquids

Installing the pump

• Do not place the pump where it can become clogged with debris or gravel. Do not set the pump on the
bottom of the pond to prevent the pump from draining the pond. Monitor the pump regularly to make
sure the intake remains unclogged.
• Plug the pump into a ground fault interrupter (GFCI) protected outlet that is in a dry place, protected
against any risk of ooding. Verify that the power supply voltage and frequency match the specications
