A sump pump takes rainwater and ground out from beneath your home and from the perimeter drainage. This helps prevent water entering your basement and penetrating your foundations. For it to function correctly, it needs to have a periodic inspection done by a professional. Here are items usually checked during an inspection:
After the visual inspections, the pump professional will also test if the pump is working. The actions will depend on the type of sump pump. Pedestal-type pumps have a lever that needs to be pulled to check the pump. Electrical safety rules should be in place at all times. Submersible pumps have a pressure switch or float that can be pulled with a stick. Another way to test the pumps is to pour water into the sump pit to activate the pump.
Every sump pump has a manufacturer manual with recommended frequency for inspections. Read it to know the right servicing and maintenance procedure. Some would require it to be done monthly, while others would only need a quarterly professional inspection.
