We have an inground pool that was installed by a local dealer. It's a
vinyl-lined pool with concrete walls, and holds about 22,000 gallons of
The dealer also provided a pump, sand filter, and chlorinator feed tank
(sorry if my terminology is incorrect).
We've had the pool for 4 years, and the pump/filter system seems to
have worked fine, except for 1 overheating incident when the water
level got too low in the pool.
This year, the pump motor, hummed, smoked, then quit, so I'm looking to
Here's my question: This pump unit is a Jacuzzi S15LR-3. Most of the
Internet sites on which I've been able to find it list it as an
"above-ground" pool pump. I called a couple of places to find out the
difference between an "above-ground" and an "in-ground" pool pump.
One place said that above-ground pumps weren't self-priming, and
therefore depended upon being lower that the pool water level. This
confuses me a bit since every place I've seen it listed describes it as
a self-priming pump. My own experience as been that an inch or two of
residual water in the pump has always been enough for it to create
enough vacuum to fully prime itself. Only when the pump has been
completely dry have I had to prime it manually.
Another place stated that because it is an above-ground pump, it
doesn't have a "diffuser" (no explanation of what that is) and
therefore can't be used with in-ground pools.
Is this all hype? Obviously, this pump has worked for 4 years with my
in-ground pool (given that I've occasionally had to manually prime it.)
I've noticed that, at a given horsepower, all of the "in-ground" pumps
tend to be higher-priced.
Thanks for any info...
