Excellent information if you currently own or are about to own a sump pump


At least twice a year, preferably before the local wet season and before and after major storms, sump pumps should be thoroughly checked for proper operation. Manufacturer instructions should be used as the primary guide for pump installation and maintenance, but here are some general inspection and maintenance guidelines from HouseMaster.


With the pump cord disconnected:


  • Make sure there is a grounded three-prong receptacle for the sump pump.
  • Ideally the receptacle should be installed at least 18 inches above the floor.
  • The receptacle should also be close enough so that the pump cord (usually a maximum of 6-feet long) can be plugged directly into the receptacle.
  • If a Ground-Fault-Circuit-Interrupter (GFCI) is installed at the receptacle outlet or in the electric panel, make sure it is working. Use the test button on the unit to confirm proper ground-fault protection.*
  • Remove the pump if possible and check for any corrosion, damage, or blockage of the pump components.
  • Inspect the sump pit for any silt or debris lesbian porn that might obstruct the float or clog the pump intake or discharge tube
  • Make sure the pump is positioned so that the movement of the float that turns the pump on and off is not obstructed by the walls of the pit or other objects.
  • Set the float height to start the pump at a lower or higher level as needed. The float should be set so that it keeps the water toward the bottom of the sump pit at the normal high water line.
  • Check the drain line from the pump to the termination point on the exterior for any signs of corrosion, holes, damage or signs of leakage.
  • Make sure the line is secured every three feet or so.
  • Add a check valve in the discharge line at the pump if not present.


Once the visual check is made, an operational check can be performed:


  • Confirm the pump plug is securely plugged directly into the receptacle. (Once again – no extension cords).
  • If the sump pit is empty, add enough water, if possible, to confirm the pump turns on and off properly.
  • With a sump pump with automatic preset sensor switches; if water exceeds the top of the pump before turning on, or if the pump does not shut off when water drops again, there may be a defective sensor or other problem. Refer to the manufacturer set up instructions.
  • If the pump uses an adjustable float switch, the pump should turn on at the set “on” level and off when the water level drops.
  • The pump should not have to run all the time. If it does, try setting the float or pump higher in the pit. If this doesn’t help keep the water from the top of the sump, a larger pump may be needed.
  • Check the drainline and connections for any leaks.
  • Go outside and check the drainline discharge point. It should be positioned to discharge the water at least 5 -10 feet from the foundation at a point where the runoff doesn’t cause ponding or backflow of water toward the foundation or erosion.
  • In areas subject to freezing temperatures, precautions must be taken to make sure the drain line does not freeze up or get blocked by ice or snow.
  • Sump pumps should not be connected to sanitary sewer systems (unless locally approved) or private sewage (septic) systems.


Backup pumps and alarms:


  • If you do not have a backup, consider adding one, especially if your pump runs regularly or there is a high flood potential.
  • If your sump milf porn system is equipped with battery backup, check the manufacturer maintenance instructions. It may be necessary to check the battery water level to make sure it covers the cells.
  • Inspect the backup pump setup in the pit for obstructions etc., as was done for the primary pump.
  • The float should be set or pump positioned so it only activates if the primary pump does not.
  • Unplug the primary pump and add water to the pit (if possible) so that the backup runs.
  • Plug the primary cord back in after the backup test is complete.
  • If you have a high water alarm, it should activate when the float is raised, or if sensor type, when the water hits the sensor.
  • Depending on the set up, an alarm may sound when the primary is unplugged or when the backup activates.

*Note: A Ground-Fault Circuit Interrupter (GFCI) is a safety device. A GFCI could trip for various reasons, rendering the sump pump inoperative. While it may not be required, if a GFCI is present, check regularly to make sure the GFCI is on and sump pump is operational.
