  "summary": "Pump unit, pit, discharge line, and battery backup costs in one estimate.",
  "description": "Sump pump installation cost is driven by the pump itself, the labor to dig or access the sump pit and run a discharge line to daylight or the storm drain, and whether a battery backup system is added for power-outage protection. A basic pedestal or submersible pump runs $100-$400 for the unit, while installation labor including pit prep and discharge piping typically adds $400-$900 for a straightforward job in an existing basement. Homes needing a new pit excavated through concrete, a longer discharge run, or a battery/water-powered backup system will run meaningfully higher — battery backup systems alone typically add $400-$1,000 installed. This calculator totals the pump, base installation labor, and optional backup system so you can compare a plumber's quote against 2026 US national averages; always confirm whether a quote includes a check valve and whether the discharge line meets local code for distance from the foundation.",
  "formula": "Total = Pump Cost + Base Install Labor + (Backup System Cost if selected) + Discharge Line Extension Cost.",

  "faq": [
    {
      "q": "Do I really need a battery backup?",
      "a": "If your area loses power during storms — exactly when a sump pump is needed most — a battery or water-powered backup is strongly recommended, since a single power outage during heavy rain can lead to a flooded basement without one."
    },
    {
      "q": "Pedestal vs. submersible pump — which costs less?",
      "a": "Pedestal pumps are cheaper upfront ($60-$150) and easier to service since the motor sits above the pit, but submersible pumps ($100-$400) are quieter and preferred for finished basements despite the higher unit cost."
    },
    {
      "q": "How often does a sump pump need replacing?",
      "a": "Most sump pumps last 7-10 years with normal use. If yours runs constantly, makes grinding noises, or is over a decade old, replacement before it fails during a storm is generally cheaper than emergency water damage."
    },
    {
      "q": "Where should the discharge line empty?",
      "a": "Local code typically requires discharge at least 10-20 feet from the foundation, directed away from the house and any neighboring property, and never into a sanitary sewer line — check your municipal code before finalizing the route."
