How to Install a Sump Pump in a Crawlspace
Sump pumps are used to carry away water that might otherwise collect in a basement, crawlspace, or other low area of your house or other structure.Installing a sump pump in a crawlspace may be a bit of a challenge, as you will be probably be working in pretty tight quarters. However, most sump pumps are fairly compact, so hopefully it won’t be too bad. Just buy the smallest one that will still get the job done. Does this Spark an idea?

Instructions
-
-
1
Make sure the sump pump is not receiving any power from any electrical source. (See WARNINGS for more information.)
-
2
Provide a level, solid base for the sump pump to set on. Cinder blocks or a sturdy piece of wood slightly larger than the pump will work.
-
-
3
Make sure a hole has been drilled somewhere in the discharge pipe so that air can flow through the pipe. Otherwise, the pump will not operate properly. Then install the discharge pipe from the sump pump itself to where you want the excess water to drain. (See WARNINGS for further information.)
-
4
Make sure the sump pump has some type of way to keep water from flowing back into the pump. You may need to install a check flow valve or other similar device.
-
5
Attach the cord providing power to the pump to the discharge pipe. Make sure it is secure.
-
6
Connect the pump to the electricity source. Restore power to the outlet and pump.
-
7
Fill the pump with water first and then test it to see if it is working properly. Do not test or operate the pump without water in it.
-
8
Make sure the pump has enough water in it so that the water reaches the level to where the pump will know to turn on. Add water or re-fill the pump, if necessary.
-
9
Install a cover at this time, if you wish. (See TIPS for more information.)

Tips & Warnings
Measure the space where the sump pump will be located. This way, you will be sure to purchase one that will fit. (See WARNINGS for further information.)
A sump pump cover will protect the pump itself, prevent it from becoming clogged or filled with dirt or debris, and will help keep down any odors that may form. So, you might want to consider installing one.
Disconnect the pump, unplug it, do whatever is necessary to make sure no power is running to or through the pump. If necessary, turn off the power to the house or building where the sump pump is located. Severe electrical shock can occur, causing injury or death.
Make sure the pump is clear on all four sides. Do not let it touch or set against anything.
Make sure the sump pump is draining into or through something it should be. It should not drain into or near a water supply that is or can be used for drinking or other similar purposes.
Make sure to check and see if you need any permits to install a sump pump.
