Pedestal vs. submersible
Pedestal
- Cheaper and easier to service
- Motor sits above the pit
- Louder
- Good for shallow, narrow pits
Submersible
- Quieter, motor sealed in the pit
- Handles more water and debris
- Costs more
- Harder to service
A battery backup pump keeps working during power outages, when storms make flooding most likely.
What plumbers charge for this job
Most of the price of a plumbing job is labor. Licensed plumbers in the U.S. typically charge $45 to $150 per hour, and many add a $50 to $200 service call fee that often covers the first hour. Expect evening, weekend and holiday visits to cost noticeably more; emergency hourly rates commonly run $150 to $350. Master plumbers and plumbers in high-cost metro areas sit at the top of these ranges.
Before work starts, ask whether the quote is a flat price for the whole job or an hourly estimate, and whether parts, permits and haul-away are included. See Plumber rates per hour and Emergency plumber cost for the full breakdown.
What affects the price
- Whether a pit already exists
- Breaking and patching a concrete floor
- Discharge line length and exterior work
- An electrical outlet near the pit
- Adding a battery backup or alarm
DIY or professional?
Replacing a pump in an existing pit is a common DIY job. New installations involve concrete cutting, drainage and electrical work, so most homeowners hire a plumber or waterproofing contractor.
How to save
- Test your pump each spring by pouring water into the pit.
- Replace a failing float switch ($35 to $70) before replacing the pump.
- Replace pumps before storm season, not during a flood.
