How long should a pool pump last?

I don't know about "should", but over 20 years my experience is 2-5 years

Learn to replace bearings, capacitors, and/or leaky seals, and you can milk a a lot of extra work out of them, and a lot cheaper, with just a bit of effort

20+ years, bearings every 4-5 years.

I’ve been through a few bearings but my pump is just oxidized aluminum with no paint on it at this point. The inside is nice and shiny.

Motor is shot. $500 just for the motor.

I rebuild the seals whenever there is evidence of leaking. The motors last for at least 4 or 5 years. I run mine sometimes 24/7 in the summer months to keep the pool cooler using the spray return.

A pool pump motor should not be $500 and the motors are rarely the part that goes out. They are pretty easy to rebuild or swap a motor.

A good PMSM with controller is about a thousand. Double through pool companies. 1-2 speed single phase motors will end up costing much more on your power bill. It isn’t just about motor efficiency, it’s about being able to dial in just the flow you need without pressuring up your system.

My first one lasted 14 years, so pretty good. I had a 4 speed but went to a single speed for the new one as I rarely altered the speed anyway and was half the cost.

Mine died yesterday. Saw it (and heard it) coming

It’s been really loud for few months. I had some other work done. Guy told me it’s likely in its final days.

Yesterday it didn’t come back on at 8am. Having it replaced Monday


$2700

Got a Pentair setup with 1 hp pump. Relaced at 4 years and at 8 years just last week. Starts humming loud and leaking at the bottom at the pump joint.

They are now lasting about that long. Amazon has whichever you need for around $200. You can change the motor in 20 minutes with only a socket wrench needed. The pump part (the front that the motor mounts onto is most likely fine. It could be just the start / running capacitor - always keep an extra on hand for only $15. Pop the back end cover (about the size of a quarter) off of the motor and give the drive a spin with a screwdriver. If it wont try to get going, its probably a dead capacitor. If the motor is truly shot, you'd probably have heard the bearings grinding for a while now.
