What affects the cost?

  • Pump type: pedestal replacement runs $400-$600 installed versus $800-$2,000 for a submersible replacement (HomeAdvisor)
  • Scope of the swap: a straight pump-for-pump replacement in an existing pit runs $350-$1,000 (HomeGuide, This Old House), while a fuller job that also touches the discharge line or backup system runs $700-$1,600 (Fixr)
  • Labor rate and time on site: plumbers charge $45-$200 per hour, and a replacement typically takes about an hour versus 2-4 hours for a brand-new installation (Bob Vila, HomeAdvisor)
  • Old pump removal and disposal, commonly $100-$200 (Fixr)
  • Discharge line or check-valve work done during the swap: Fixr cites discharge pipe replacement at $175-$600
  • Repair vs. replace decision: repairs average $309-$755 (HomeAdvisor) or $150-$500 (Fixr) or $200-$500 (Bob Vila); once repairs get frequent or the pump nears the end of its roughly 10-year service life, replacement is usually the better value (HomeAdvisor, This Old House)
  • Pump age and expected remaining lifespan: pedestal pumps can last up to 25-30 years while submersible pumps typically last only 5-15 years, so pump type affects how soon you'll face this cost again (HomeGuide, This Old House, Fixr, HomeAdvisor)
  • Installation location and access: basement replacements run $310-$750 while outdoor units run $1,250-$2,500 due to harder access (HomeAdvisor)

How much does it cost to replace a sump pump?

Replacing an existing sump pump costs $350 to $2,000, averaging around $900. The number moves mostly with pump type: HomeAdvisor puts pedestal pump replacement at $400 to $600 installed, and submersible pump replacement at $800 to $2,000. HomeGuide and This Old House both put a basic straight swap — pump for pump, into a pit that’s already there — at $350 to $1,000 for materials and labor. When the job includes more than a like-for-like swap, such as new discharge piping or a check valve, Fixr’s “full replacement” figure of $700 to $1,600 is a better guide. Most homeowners land in the $500 to $1,200 range for a typical job; jobs that push toward $2,000 usually involve a submersible unit plus extra plumbing work.

Should you repair or replace your sump pump?

Repair first if the pump is relatively new and the fix is minor — a repair averages $309 to $755 (HomeAdvisor), $150 to $500 (Fixr), or $200 to $500 (Bob Vila), all well under the cost of a new unit. Replace once repairs start piling up or the pump is nearing the end of its expected service life. Lifespan depends heavily on pump type: pedestal pumps are commonly rated for up to 25 to 30 years (HomeAdvisor, HomeGuide, This Old House, Fixr), while submersible pumps typically last only 5 to 15 years because the motor sits submerged in water (HomeGuide, This Old House, Fixr). Bob Vila’s more conservative 7 to 10 year average likely reflects budget submersible models rather than a premium pedestal pump. If you’re paying for a second or third repair on a pump that’s already past its typical lifespan, put that money toward a new pump instead.

What affects sump pump replacement cost?

  • Pump type. Pedestal replacement runs $400 to $600 installed; submersible replacement runs $800 to $2,000 (HomeAdvisor).
  • Scope of the job. A straight pump-for-pump swap costs $350 to $1,000 (HomeGuide, This Old House); adding discharge or valve work pushes it to $700 to $1,600 (Fixr).
  • Old pump removal. Hauling away and disposing of the old unit commonly adds $100 to $200 (Fixr).
  • Labor rate and time. Plumbers charge $45 to $200 per hour, and a replacement typically takes about an hour versus 2 to 4 hours for a new installation (Bob Vila, HomeAdvisor).
  • Discharge line or check-valve work. Fixr cites discharge pipe replacement at $175 to $600 if that’s part of the swap. Richard Trethewey, This Old House’s plumbing and heating expert, explains why that piping matters: “We want the water to go as far away from the house as we can so it doesn’t come back.”
  • Location and access. Basement replacements run $310 to $750, while outdoor units run $1,250 to $2,500 because of harder access (HomeAdvisor).

How can you keep sump pump replacement costs down?

  • Choose a pedestal pump if your pit allows it. Pedestal units cost $400 to $600 installed versus $800 to $2,000 for submersible (HomeAdvisor) — and pedestal pumps also tend to last longer, up to 25 to 30 years.
  • Don’t wait for total failure. Watching for early signs and replacing before the pump dies avoids emergency service surcharges and water damage, and keeps the job a routine $350 to $1,000 swap (HomeGuide, This Old House) instead of a rushed job.
  • Bundle discharge or valve work into the same visit rather than calling the plumber back separately — a combined job runs $700 to $1,600 (Fixr) but avoids paying for a second trip.
  • Get more than one quote, especially if your pump is a submersible model or your pit is in a hard-to-reach spot like a crawl space or outdoors, since labor for those setups runs higher ($1,250 to $2,500 for outdoor installs, per HomeAdvisor).

Prices vary by region, pump brand, and how much extra plumbing work is involved, so treat these figures as a planning budget. Get two or three local quotes, and ask directly whether old-pump removal and any discharge or valve work are included before you commit to a number.

Frequently asked questions

How much does it cost to replace a sump pump?
Most straight swaps into an existing pit run $350 to $1,000 for materials and labor (HomeGuide, This Old House). By pump type, HomeAdvisor puts pedestal replacement at $400 to $600 and submersible replacement at $800 to $2,000 — the wider spread accounts for higher-capacity units and any discharge or valve work bundled in.
Is it cheaper to replace a pedestal or a submersible pump?
Pedestal replacement is cheaper at $400 to $600 installed versus $800 to $2,000 for a submersible unit (HomeAdvisor). Submersible pumps cost more upfront but sit hidden below the pit lid and handle higher water volumes.
Should I repair my sump pump or replace it?
It depends on the pump's age and the repair bill. Repairs average $309 to $755 (HomeAdvisor), $150 to $500 (Fixr), or $200 to $500 (Bob Vila). Once repairs get frequent or the pump is nearing the end of its typical service life, replacing outright is usually the better value (HomeAdvisor, This Old House).
How long do sump pumps last before they need replacing?
It varies by type: pedestal pumps commonly last up to 25 to 30 years, while submersible pumps typically run 5 to 15 years (HomeGuide, This Old House, Fixr, HomeAdvisor). Bob Vila cites a more conservative 7 to 10 year average, which likely reflects budget submersible models rather than premium pedestal units.
Does replacement cost include removing the old pump?
Not always — check what your quote covers. Fixr cites old pump removal and disposal separately at $100 to $200 on top of the new pump and installation labor.
Is replacing a sump pump cheaper than a new installation?
Yes. Replacement skips the cost of digging a new pit and cutting the basin, which is why This Old House and Bob Vila both note that swapping an existing pump is significantly cheaper than a first-time installation.
What if my replacement also needs new discharge piping or a check valve?
That pushes the job toward the higher end. Fixr's 'full replacement' figure of $700 to $1,600 covers a new pump plus labor when discharge or valve work is part of the job, and cites discharge pipe replacement alone at $175 to $600.
How much do plumbers charge per hour for sump pump replacement?
Expect $45 to $200 per hour (Bob Vila, HomeAdvisor). A straight replacement typically takes about an hour, compared with 2 to 4 hours for a brand-new installation (Bob Vila).

Average sump pump lifespan 7-10 years; better-quality pumps can last 10-30 years.

This record covers REPLACING an existing sump pump (a swap into an existing pit) rather than a first-time installation that requires digging a new basin - that scope is covered by the separate sump-pump-installation-cost guide. Two sources give a direct 'replacement' figure and agree closely: HomeGuide and This Old House both cite $350-$1,000 for a straight swap including materials and labor. HomeAdvisor's repair-focused page instead breaks replacement down by pump type: pedestal $400-$600, submersible $800-$2,000 - its submersible figure is the widest number any source ties specifically to 'replacement,' so it anchors range_high_usd. Fixr's 'full replacement' figure ($700-$1,600) sits between the HomeGuide/This Old House band and HomeAdvisor's submersible band, likely because it factors in more discharge or valve work alongside the pump swap. Bob Vila and HomeAdvisor's general installation pages quote $1,200-$2,500 (average $1,500) and an average of $1,363 respectively, but those cover full new installations including pit/basin work and are not directly comparable to a replacement-only job, so they are not used for the headline range - they are cited here only for repair-cost and lifespan context. range_low_usd=350 and range_high_usd=2000 span the full spread from a basic pedestal swap to a submersible replacement with extras. national_average_usd=900 is a synthesized midpoint between HomeAdvisor's pedestal-replacement average (~$500) and submersible-replacement average (~$1,400), and it sits inside Fixr's $700-$1,600 full-replacement band; project_low_usd/project_high_usd ($500-$1,200) marks the 'typical' zone where most straight swaps land, with submersible-plus-extras jobs pushing toward the $2,000 high end. On repair vs. replace: all sources agree that once repairs become frequent or the pump nears the end of its typical service life, replacing outright is the better value. Lifespan estimates vary by pump type and source: pedestal pumps are commonly cited at up to 25-30 years (HomeAdvisor, HomeGuide, This Old House, Fixr) while submersible pumps run only 5-15 years (HomeGuide, This Old House, Fixr) - Bob Vila's more conservative 7-10 year average likely reflects budget submersible units rather than premium pedestal pumps.
