1/2 HP Shallow-Well Cast Iron Jet Pump is rated 2.6 out of 5 by 5.
Rated 5 out of 5 by from Flotec FP4112 shallow well pump There I was in the middle of a shower and the water stopped. My 6 year old expensive 1hp well pump died. I was told originally by the installer that the well pump was setup for 120 volt, PLEASE NOTE this installer put in 15 90deg elbows which gave very low water pressure. I went to work with a hacksaw and went from 15 to 4 90deg elbows which greatly improved water pressure but the well pump always seemed to take a long time building up pressure and at times overheated. Well I went to Home Depot and got their Flotec ½HP FP4112 shallow well pump because it design was similar to the original but much smaller. I was actually having second thoughts because the Home Depot well pump was so much smaller. The plumbing was easy since the inlet and outlet were almost identical but I did have to relocate the Redheads for the mounting base. There was an irritating situation, as I stated the installer said the original well pump was 120 volt well I checked the voltage it was 3 wire 240 volts, real smart installer. This Home Depot ½HP comes setup for 120V but an easy turn of a knob gets you to 240V. I flipped the electrical switch ON and saw the pressure gauge rocket up to 45PSI much faster than the original well pump ever did. This Home Depot well pump is ½ the price of the original 1HP well pump and does a better job

Rated 5 out of 5 by from A major money saver Used this pump by itself without a tank for outside watering on an existing well where the pump burned out. Used it to fill my new 5000 gallon swimming pool. I would have spent more money on the water bill from the city than it cost for the pump. Note I did have to buy new fittings for the outside piping but thats to be expected. All in all, Very happy and glad I got the cast iron model as it will last longer than the cheaper version of the same pump.

Rated 1 out of 5 by from Do not buy this pump This pump caused me nothing but nightmares. Do not buy this pump unless you want issues. I purchased the pump to replace an existing that went out and it worked for a week until it was unable to build up pressure to kick off. It lead me to replace my whole suction line...still didn't work. Replaced the impeller, gaskets, and seals...still didn't work. So at about $1,000 in to the project I had a plumber bring out a more expensive pump that starts with a G, and my problem was solved. This pump was junk from the start and lead me to believe there were other problems with my well system. Save the headaches and buy a more expensive better make and model.

Rated 1 out of 5 by from Kept burning Out After having the same pump in the house for 30+ years the old pump finally went out. I bought the flotec, 2 years later it burnt out on me. I figured it was a fluke so I went and bought another one. That one didn't even work out of the box. I took and back and went with another brand.

Rated 1 out of 5 by from Not good We have had this pump for less than 4 years. It started smoking and is running very hot. Spend the money and get a better pump.
