Visual Warning Signs Your Pump is Dying
– Small puddle under pump that wasn’t there last month

– Gap developing between pump and plumbing
– Cracks in concrete pad beneath pump
Timeline: 3-6 months before catastrophic failure
Performance Issues That Signal Death
| Performance Problem | What’s Failing | How to Test | Death Timeline |

The 5-Minute Dying Pump Test
Turn pump off. Spin motor shaft by hand through back vent.
– Smooth and quiet = GOOD
– Grinding or rough = BEARINGS DYING
– Won’t turn = SEIZED (too late)
Start pump, stand 3 feet away.
– Steady hum = HEALTHY
– Squealing/screaming = BEARINGS DYING
– Grinding = IMPELLER DAMAGE
– Clicking = ELECTRICAL FAILING
Look under and around pump.
– Dry = GOOD
– Small drips = SEAL WEARING
– Puddle = SEAL FAILED
– Rust stains = CHRONIC LEAK
After running 1 hour, carefully touch motor.
– Warm (can hold hand on it) = NORMAL
– Hot (uncomfortable to touch) = RUNNING HOT
– Burning (can’t touch) = OVERHEATING BADLY
Check pool returns and pressure gauge.
– Strong flow, steady pressure = HEALTHY
– Weak flow = IMPELLER/MOTOR ISSUES
– Pulsing flow = CAVITATION
– No flow = MAJOR FAILURE

Frequently Asked Questions About Dying Pool Pumps
A pool pump can die instantly from power surge or seize without warning, but usually gives 1-3 months of warning signs. The most common pattern we see: slight noise for 2-3 weeks, gets louder for 2-3 weeks, then rapid failure within days. Catastrophic failures (pump working fine Monday, dead Tuesday) account for only about 10% of pump deaths. The other 90% give clear warnings – squealing, leaking, overheating, or declining performance that gradually worsens until failure.
The #1 sign is new or worsening noise – especially high-pitched squealing that indicates bearing failure. This accounts for 40% of dying pumps we see. Second most common is shaft seal leak (25%), followed by declining water flow (20%). In coastal Orange County, visible rust/corrosion is also a major indicator. The key is ANY change from normal – pumps don’t get better on their own, they only get worse.
Yes, IF you catch it early. A pump making slight bearing noise can be rebuilt for $300-400. Wait until it’s screaming? Too late – shaft damage means new pump. A small seal leak fixed immediately costs $175. Ignore it for 2 months? Water destroys the motor – $600 replacement. The key is acting within 2-4 weeks of first symptoms. After that, cascade failure usually makes repair more expensive than replacement.
Never. Running a dying pump causes cascade damage that triples repair costs. Example: bad bearings ($300 fix) destroy the shaft ($600 motor), which damages the seal plate ($200), which cracks the volute ($400). What started as a $300 repair becomes a $1,500 replacement. Plus, catastrophic failure can damage other equipment, trip main breakers, or even cause fires. When you hear/see warning signs, stop using the pump and get it diagnosed.
Realistically, 1-3 months max, and that’s risky. We see homeowners try to “baby” dying pumps by running them less, manually helping them start, or constantly adding water for leaks. This might buy you 4-6 weeks, but you’re gambling with a $1,500 emergency replacement during peak season when contractors are booked. Better to schedule replacement on YOUR timeline than have it fail during your kid’s pool party or heat wave when you need it most.
Three things kill OC pumps fastest: running 24/7 (kills pump in 2-3 years), ignoring shaft seal leaks (motor dies in 8-12 weeks), and salt air within 3 miles of coast (40% shorter life). Also, our hard water (250-400 PPM) creates calcium buildup that destroys seals and impellers. The combination of salt air, hard water, and people running pumps continuously creates perfect conditions for premature pump death.
