    Add check valves to pump outflows. Put a simple check valve on the outflow discharge pipe of any sump pump. This will stop water from flowing back into the sump pit after the pump shuts off. This keeps the area pumped dry.

    Expert Answer
    Try to clean out your sump pump pit around once or twice a year, if you can. Over time, grit or dirt can get into the sump, which can foul the pump.

  • Question
    Can I put bleach in a sump pump to clean it?
    Community Answer
    I would use CLR. Bleach has chlorine, which can initiate or accelerate corrosion of some components.

      Warnings

      • When re-positioning the sump pump in the pit, be sure that the float is freely moving. If it becomes stuck, your pump will either stay on and burn up or stay off and flood your house.
