How To Install a Sump Pump in a Crawlspace

Are you constantly dealing with flooding in certain areas of your house, particularly a crawlspace?  If so, your recurring problem can be solved by installing a sump pump.  A sump pump is a device that will pump water from a particular area and deliver it to an exhaust area.  Yes, it is that simple to understand.  That said if a particular crawlspace in your basement or any other area in your house keeps flooding, then installing a sump pump is the answer.  The only problem is that installing this device into a small space can be somewhat tricky and inconvenient.  Nevertheless, if you want to keep that particular area of the house flood-free, then here are the steps on how to install it.

  • Choosing the sump pump.  When picking out the sump pump to use, the only real consideration to keep in mind is dimension.  Basically, you will want to get a compact sump pump big enough to fit through your crawlspace.  In addition, you will need to have the discharge tube or pipe that comes with the device long enough to reach the drainage area where you want the water to flow to.  
  • Cut the power.  Before proceeding with the installation, make sure that the power to the sump pump is disconnected.  You really do not want fiddling with any device that is currently receiving electricity.  
  • Set the sump pump.  Set the sump pump on some type of base, wood or concrete blocks would do fine provided that it is level.  This should be done inside the crawlspace.  
  • Install the discharge tube or pipe.  The next step will involve preparing and installing the discharge tube.  First off, you will need to ensure that the tube is long enough to reach the drainage area.  With that out of the way, the next thing that you will have to do is to drill a hole into the tube.  This is important since you will need to have a constant supply of air coming into the tube.  Without it, the sump pump will cease to function properly.  Once that is done, it is time to install the tube.  One end should be connected to the pump and the other end at the drainage area.  
  • Install the one-way valve.  Also known as the check-flow valve, the one-way valve is a component that will be installed in the tube that will ensure that the water will not change its direction and flow back into the pump.  This valve should be installed near the end of the discharge tube connected to the pump.
  • Test the pump.  With all the components properly installed, check if it works.  Connect the pump to the power source and fill it up with water at the level where the pump will automatically turn on.  

If the pump works great and the water is transported to the drainage area, then wait for the pump to exhaust the water in it and install the protective cover of the pump.  Once that is in place, your job is done.
