Question: Can I use this pump to drain water from a swimming pool?
Document: Owned a Zoeller that crapped out after 3 years so I figured I'd give this a try. A plumber told me to get something overpowered for the applications and this 1/2 hp seems to fit the bill. It runs several times per hour and has a strong pull - water literally shoots out of the discharge pipe outside of my home where my old pump slowly trickled. I've had a flotec submersible pump that I use for the pool/etc and it has been running strong for over 20 years.
I have a sump which is has water all year round. These sumps work great; These plastic ones last for several years before something rusts out. One thing I do is use a plastic tie strap to adjust the float to the level I want. I've had the screw which holds the float down rust out... not good. The tie strap resolved it.
Acquired this pump used as part of a shop asset purchase. The pump has been operating in an oil/water separator sump that gets constant use throughout the day. Guys in the shop told me it had been "down there" for at least several years in the muck and gunk. Pulled it out when it finally got clogged, but it keeps ticking after being cleaned out. This is one impressive piece of equipment.
This sump pump works well. Easy to set up, but the documentation on using the pump in a system could use some improvements. The pump is fast and reasonable quiet. I have had this model before and they are reliable, my last pump of this type has been working for (5) years with no problems.
I got this to replace a pump that failed just after hurricane Sandy. It worked ok for 3 months with intermittent use and had never been run dry but now the motor won't start most of the time and seems like it's trying to seize up. Not good for a pump this pricy after so little time. Avoid.
This is my third Flotec 3200A pump in about ten or twelve years. They wear out after three or so years, so I keep a spare pump and check valve on hand. If you use the same pump each time, it is a very fast swap-out. On a normal day this pump runs about two times, more  frequently after a heavy rain. This pump has good volume, price, and longevity.
If you happen to block the movement, as I did, then the pump will not run.Once all connected however, this pump moves water and fast. We emptied the sump pit in about 10 seconds. One big whoosh and the water was gone.I am pretty impressed so far.UPDATE APRIL 2014Float is broken.
ORIGINAL REVIEWFollowing "Irene", we determined that our primary sump pump had failed. Went down to the orange big-box hardware store (sorry Amazon, but I needed it that day).Installation would have been pretty easy, except I have a complicated set-up. I also have a back-up water powered (venturi) pump and the lid to the pit is sealed up.
I have a crawlspace that runs anywhere from 12" to 18" high (extremely tight), 3 houses from a lake. The house is on very low land (the land is actually at lake level), and if the weather so much as drizzles, there is standing water under the house. In the Spring and Fall, this Flotec pump kicks on roughly every 2 minutes, 24 hours a day, during these rainy seasons.
When I fill the basin with water though, nada. So the backup pump is keeping me dry. Looking at a competitive site (with the words "sump pumps" in the URL) and Amazon, I saw that Liberty sump pumps all have five star ratings. Every size, every configuration, right across the board. So I got a new 457, half hp with a vertical float. Bought elsewhere due to a significant price difference.Thus, very unhappy with the Flotec pump. Poorest possible recommendation.
Answer: yes
