5. Special Advice to Keep in Mind

  • Make sure that the discharge outflow pipe is as brief as possible and limit as few turns as you possibly can.

  • Make sure that the discharge size from the pump’s outflow is the same diameter as the discharge pipe to minimize pipe friction deficits.

  • Always place a connection in the discharge line, right on top of your sump pit, to allocate quick removal of the unit for any repair or maintenance as well as cleaning.

  • Be sure to bore a weep or air hole at about 1/8-inch or 3/16-inch diameter whenever a check valve is placed in the discharge outflow. Place this weep hole under the floor line amid the discharge pipe and the check valve.
  • Never try to activate the pump without any groundwater as this can result in permanent damage to your sump pump.

6. Keeping Your Sump Pump Healthy and Working

  • Never attempt to start the pump in a dry pit. This can cause the surface temperature of the pump to rise to critical levels and overheat the motor.

  • Secure the power cord to the discharge pipe using an electric tape to guard the cord from destruction.

  • Provide a suitable sump pit cover to stop solid debris from plugging the pit, stop formation of odors, and protect you against any accidents.

  • Do not try to open the permanent seals of the motor housing to replace the oil within. A high-grade dielectric oil especially made for this model has been placed into the motor casing during manufacture. The use of other kinds of oil can permanently render your pump useless and void your warranty coverage.
