How to Build a Sump Pump Battery Backup System

A pump which is used to remove the water that is deposited in a sump pit is called a sump pump. A sump pump helps in removing water from the place where it is deposited to a different place. A back up system for sump pump is needed during power cuts, to ensure the sump pup is able to remove water from sump pits without any power as well. When there is unwanted water in a residence, the sump pump helps in removing it very easily. Due to heavy rains, the basement of a flat may get filled with water and in such situations sump pumps are very useful. Usually, a sump pump comes with a set of tools like cables and all that is required by you is to purchase a marine battery for building the backup system.

Installing a battery backup system to your sump pump gives extra protection from floods. During power failure, the main pump fails to function and the back up pump needs to remove excess water. The article further discusses how to build the sump pump battery backup system.

Things You'll Need

  • Elbow Check Valve
  • Hack Saw
  • Drain line
  • PVC cement
  • PVC pipe cleaner
  • Bracket
  • Marine Battery
  • Battery case
  • Screw Driver
  • Battery charger
  • Electrical cables
  • Pliers

Step Number 1: Placing the Pump

Install the back up pump such that it is not interfering the main pump unit.The pump will fit to the PVC drain pipe or support of the main pump with respect to its model. By Keeping the pumps low in the pit, you can remove out or pump out maximum amount of water. Some models depend on a bracket that will be placed on the pit edge.

Step Number 2: Placing the Adaptors

There will be a drain pipe above the check valve. Now cut through the main drain pipe away from the joints so that the check adaptor can be placed.Both ends of the pipe must be cleaned using a pipe cleaner. Use cement to place the adaptors firmly to its place. The check adaptor prevents the water from being pumped to the back up pump when main pump is pumping

Step Number 3: Installing the Drain Line

Once the check adaptor is placed, a drain line is installed from the check adapter to the outlet of the backup pump.

Step Number 4: Connecting the Power Cables

Connect the power cables to the pump and marine battery. Ensure that the cables are connected properly and during operation it should not be caught by either of the pump. The battery charger should not be connected to the battery simultaneously. The charger is then plugged to a GFCI (Ground Fault Circuit Interpreter) outlet that provides maximum protection. The outlet has to be on an independent circuit line that should not be supplying power to any other areas of the residence.

Caution: You need to be careful and take extra care and precaution when you work with electricity. Use rubber gloves, footwear and devices that have insulated handles to prevent shocks and surges.
