I have a 1hp pump for an in-ground pool. I don't know how old it is - we
bought the house almost 3 years ago.
I have 2 questions:
1) At the end of last season and again this spring, when I turn the pump on
it often just sits there and hums for a few seconds, then the breaker trips.
I have to go reset it and repeat a few times before finally the pump starts
to go. Then it works fine. It's just starting that is a problem. Does this
mean I need a new pump? Or just a new motor? Or is there something else
2) I'd like to have a timer hooked up to the pump, so it automatically
starts and runs overnight. Hopefully this will save on some energy cost from
leaving it run longer than it really needs to. How expensive are there, and
how difficult are they to hook up? My pump is attached to the a switch
mounted on the wall behind it so its accessible.
Most of them are rebuildable, new bearings, new capacitor, clean the
Some pool supply places do it as a service for about half the cost of a
new pump motor.
Any decent motor shop could do the same.
Have the "start capacitor" replaced. If you have a "Leslie's Pool Supply"
store nearby, they will usually do this for a reasonable charge. They can
also advise you on a timer however, you can most likely beat their price at
HD or W W Grainger.
Now, as far as day / night pump use, I suspect most of the respondents here
don't even own a pool. In the Atlanta area, in the early part of the swim
season, I run my pump during the day. This circulates the water warmed by
the sun. Later in the summer, the pool temp. can actually be too warm.
Then I run the pump at night to help cool it. Finally, if you need even
further cooling, you might consider buying a small fountain that can be
attached to the water "return" in the pool and operate it at night. This
will definitely lower the temp.
Different techniques for different parts of the country, I suspect...
You must live up north... I'm in the Houston area and a few years ago,
I had a house that had a pool... During the latter part of the summer,
the water temperature gets into the 90Fs... More like jumping into
lukewarm bath water than a refreshing cool dip in the pool on a hot
day... Even using a sprayer to expose the pool water to more of the
night air didn't make an appreciable difference... There were no trees
shading the pool, so it got full sun exposure a good part of the
day... I considered building some sort of very large shade arbor over
the entire pool to cut down on the solar energy being received by the
pool... Something like in the following link, but considerably
When you live in a very hot climate, if you want a cool pool, you
either have to remove the heat from it or prevent the heat from
getting into it... Although it would be possible to create some sort
of refrigeration unit to reduce the temperature, I suspect the
electricity costs would be unreasonable... Reducing the solar input
into the system would definitely be cheaper...
Yep, I'm in NJ.
I've been to Houston, the climate was great but I found the flat terrain
a bit unnerving. I suppose you get used to it.
Our pool is in partial shade. It can reach 90F, when I run the heater.
Without that, a peak temperature in most years is 82F.
