Replacing a pool pump costs $200–450 installed for a standard single-speed pump, and $600–1,100 for a variable-speed model. DIY saves $150–300 in labor. Whether you repair or replace depends on one number: if the repair costs more than 60% of a new pump, replace it. Here’s the full cost breakdown and how to decide.
Repair or Replace? — Answer This First
I get asked this question constantly. Here’s my rule after 39 years of fixing pool equipment: if the repair costs more than 60% of a new pump, replace it. If the pump is 8+ years old, replace it. If the wet end (housing, impeller) is cracked, replace it. Otherwise, repair.
A new Hayward Super Pump single-speed runs $220–280 at a pool supply store. If you’re looking at a $180 motor replacement on a 9-year-old pump with a slightly cracked volute, that’s a bad investment. But a $20 capacitor on a 4-year-old pump in perfect condition? That’s an obvious repair. Run the numbers before deciding.
| Repair Type | Part Cost | With Pro Labor | Verdict |
|---|---|---|---|
| Capacitor | $8–20 | $100–150 | Always repair |
| Shaft seal | $15–28 | $150–220 | Repair if pump is under 8 yrs |
| Impeller | $25–65 | $175–250 | Repair if housing is good |
| Motor (48Y) | $80–160 | $250–380 | Repair if pump is under 7 yrs |
| Motor (56Y) | $120–220 | $300–450 | Compare to new pump cost |
| Cracked volute | $80–180 | $250–400 | Often replace full pump |
DIY pool pump replacement start to finish — plumbing, electrical, and pump mounting covered.
New Pump Cost by Type
Single-Speed Pumps — $150–350 (Parts Only)
Single-speed pumps are the least expensive to buy and the simplest to install. The Hayward Super Pump SP2610X15 (1.5 HP, the most common residential unit) runs $220–260 at pool supply stores or on Amazon. Pentair SuperFlo single-speed is $190–240. Generic brands from Amazon run $150–200 but I don’t recommend them — parts are near-impossible to find when something fails, and something always fails.
Single-speed pumps run at full speed 100% of the time. They work fine but consume more electricity than variable-speed alternatives. If you’re replacing a single-speed pump that died, seriously price out a variable-speed before buying another single-speed — the energy savings are real.
Variable-Speed Pumps — $350–800 (Parts Only)
Variable-speed pumps run at lower speeds for most of the day, consuming 50–70% less electricity than single-speed units. The payback period on the higher purchase price is typically 2–3 years in most climates, faster in warm climates where pools run 9–10 months a year. I recommend them to anyone replacing a failed single-speed pump — the math almost always works out.
The Pentair SuperFlo VS (model EC-342001) is the best value variable-speed pump I’ve recommended consistently: $380–480 in parts, reliable, and parts are everywhere. The Pentair IntelliFlo VSF is the premium option at $580–750 — better for complex automation systems. Hayward’s variable-speed options run $400–650.
Above-Ground Pool Pumps — $80–250
Above-ground pool pumps are significantly less expensive. A quality 1 HP Hayward above-ground pump runs $150–200. Intex and Bestway pumps for smaller inflatable pools run $35–80. On the small Intex units, I almost never recommend repair over replacement — the pump is worth less than the labor to open it.
Installation Cost — DIY vs. Pro
Professional pool pump installation runs $150–300 in labor on top of the pump cost. That covers disconnecting the old pump, connecting the new one to existing plumbing, wiring it in, and startup testing. Some companies charge a flat rate, some by the hour.
DIY saves that entire labor cost. The job is straightforward if you’re comfortable with basic plumbing and electrical work: union fittings, PVC cement if needed, wire connections at the terminal block. Budget 2–4 hours the first time. See our motor replacement guide for the disassembly and wiring approach — full pump swaps follow the same basic process.
Pool pump wiring is 230V in most installations. If you’re not comfortable working with 230V, hire a pro for the electrical connection and do the plumbing yourself. The hybrid approach still saves $75–150 over a full service call.
What Affects the Final Cost
Several factors push the cost up or down from the ranges above:
Existing plumbing condition: if the union fittings are old PVC that cracks when you try to remove them, you’re adding $20–50 in fittings and cement and another hour of work. On pools over 10 years old I budget for this.
Pump pad condition: a cracked or uneven equipment pad complicates installation. Re-pouring a small concrete pad runs $80–150 if needed.
Electrical work: if the new pump requires a different amperage breaker or the existing wiring is undersized for a larger motor, add $100–250 for an electrician.
Emergency vs. planned: a pump that fails mid-summer on a Friday afternoon costs more than one replaced in the off-season with time to shop. I’ve seen pool supply stores charge 20–30% more during peak season. If your pump is 8+ years old and making noise, replace it in the fall when you have time to comparison shop.
When to Replace Instead of Repair
Replace immediately if: the volute (pump housing) is cracked, the pump is 9+ years old and the motor has failed, or the repair estimate exceeds 60% of a new pump cost. Also replace if you’re on a single-speed pump that’s failed and you haven’t done the variable-speed energy cost calculation yet — do it before you buy the same thing again.
I replaced a customer’s 11-year-old Hayward single-speed last season. The motor had failed, the impeller had a chip, and the shaft seal was weeping. Total repair estimate: $340. A new Pentair SuperFlo VS: $440 installed DIY. They did the math, bought the VS, and their electric bill dropped $45/month. The $100 premium paid back in a little over 2 months.
Frequently Asked Questions
How long does a pool pump last before it needs replacement?
Eight to twelve years is the typical lifespan for a quality single-speed pump with basic maintenance. Variable-speed pumps have similar motor lifespans but the drive electronics can fail earlier — I budget 8–10 years for VS control boards. I’ve seen well-maintained Hayward Super Pumps run 16–18 years in mild climates. I’ve also seen neglected pumps fail at 5 years from shaft seal damage.
Is it cheaper to repair or replace a pool pump?
Depends entirely on what’s broken and how old the pump is. Capacitor on a 3-year-old pump: repair ($15 part). Motor on a 10-year-old pump with a cracked housing: replace the whole thing. The 60% rule works well as a quick filter: if the repair cost exceeds 60% of a replacement pump cost, replace it.
Can I replace a pool pump myself to save money?
Yes, and I recommend it for anyone comfortable with basic plumbing and electrical work. The job is a union-disconnect, replumb with new unions, and a wire reconnection at the terminal block. The voltage (230V in most installations) is the only real hazard. Shut the breaker, verify with a tester, and the rest is mechanical. You save $150–300 in labor.
How do I choose the right replacement pump HP?
Match the HP of your existing pump unless a pool professional has told you the current pump is undersized. Going higher HP doesn’t necessarily mean more flow — it means more pressure, which can stress fittings and return jets. On variable-speed pumps, HP is less critical because the speed setting determines actual flow. Match the existing HP and you won’t go wrong.
What’s the most reliable pool pump brand?
I’ve worked on all of them over 39 years. Hayward is my top pick for reliability and parts availability on single-speed pumps — the Super Pump is bulletproof when maintained. Pentair makes the best variable-speed pump (IntelliFlo and SuperFlo VS). Sta-Rite makes excellent units that often outlast everything else on the pad. I avoid generic import brands entirely — the repair math never works when parts are unavailable.
