I've got a Hayward Turbo Flo above ground pool pump (series SP2075)
that shuts off when it's hot outside or very sunny. It will stop for a
few minutes and start up again on its own.
1) Is this the end of my pump?
2) Any dangers to this?
3) Is it worth repairing? Could I do it myself?
Likely. Bearings are worn and added friction generates heat, triggering
the thermal protection shutoff switch built into the motor. You're just
on the edge of constant failure, and thus the added heat of a hot day
triggers a shutdown.
You're depending on the thermal cutout to prevent overheating. That
can't go on for long. The heat and wear will spiral into self-
destruction sooner or later. But catching on fire or the like are
unlikely, although not impossible.
In theory you can replace the bearings. In practice this is not
feasible unless you know a motor rebuilder who works very cheap.
However, if you check eBay, you can find new pumps, motors, and rebuilt
motors, very reasonably priced from dealers and repair shops doing
business there. Your local pool shop will consider this a routine item,
but they tend to charge a premium price, which they're entitled to.
I find the best strategy is to put an automatic watch on eBay, and buy a
spare pump and/or motor very very cheap, since sooner or later the run
you use today will fail.
Pool parts are not that cheap on EBay unless you just get extremly lucky. I
just built a pool and bought lots of stuff on the net. I found a lot of things
cheaper straight from a dealer than on EBay. I got my pump locally cheaper than
anything I saw on the net.
As for your pump, if the bearings are bad it will be howling.
If this is really an overheat problem it will be too hot to touch. Does it
There are a few other things that can be bad and cause that, like a stuck start
switch but if you keep cycling it like that it will be toast soon.
Are you sure it isn't just a bad connection, a switch or a faulty timer?
You just need a spider that runs for a year and alerts you. During the
season, and on any random day, you're not as likely to find bargains. You
have to search off-season and for a long time (thus the spider). I have a
spare pump or two on the shelf that I only paid $25 or $50 for.
