How to Replace Sump Pump

Posted on: October 1st, 2013 by admin

Sump pumps can fail at the most inappropriate time such as during a storm or a holiday weekend. However the process of changing a sump pump is not as complex as you would think. There is a great variety of models of sump pump, but it is important to match the new pump to your needs. You should consider how far the pump has to push the water vertically, the size of sump pit and the rate of speed you expect the pump to move gallons of water each minute.

The process of how to replace a sump pump is quite straight forward:

  • Unplug the faulty pump and ensure you secure the power cord to prevent it from falling down into the pit. Make a marker line on the bottom pipe directly underneath the check valve. Loosen the clamps on the hose at the bottom of the check valve and let it slide down the pipe. Since the check valve only allows water to flow in a single direction, in this case upwards, if you undo the top connector, all the water will be released and empty downwards soaking you. To avoid this, slide the pump one way while you gently pull the check valve towards you. You may need a screwdriver to insert between the rubber on the check valve and the pipe to allow it to loosen before moving it.
  • Once the valve and pipe have been separated, lift the pump out and allow it to drain on a couple of old towels. Remove the packaging from the new pump and familiarize yourself with the enclosed instructions. By placing the new pump alongside the old one, you should be able to note where the outlet pipe is and if it is set at the same height. If it is, this makes replacement extremely simple as you can simply unscrew the pipe on the old pump and reattach it on the new pump.
  • If the heights differ you will need to make a new pipe. If the difference is only small, you may be able to use excess pipe contained in the check valve. Use the marker line on the pipe to measure from the top of the pipe to the floor. Make a note of this length to cut a length of PVC pipe of the same diameter for the new pipe. Attach this new pipe to the new pump.
  • Once you have the new pipe installed, attach the cords to it with electrical tape or wire ties. Let the hose clamp slide down the new pipe. Place the new pump into the sump pit; tip it slightly to slide the pipe back into the check valve. Secure the check valve by sliding the clamp up. Take a second to step back and assess the pipes are straight. You may need to slide the pump slightly to ensure they are straight. Secure any excess cord and plug it in to the power outlet. The pump may not start working straight away; you may need to fill the pit until the water level is at a height to activate the switch.
  • Check for any leaks and once you are confident that it is functioning correctly, replace the cover.

Your new pump will come with some degree of warranty, so make sure you send in the warranty card and file the paperwork in a safe location with other household paperwork. Your new pump should now function properly in years to come, but if a problem develops you should consult the manufacturer information or seek professional plumbing advice. A professional can check the integrity of your system and rule out any underlying problems.
