Size Name: 1/2-HP 12-GPM 2-Wire 230-Volt Verified Purchase
I purchased this pump for watering a small, 9 tree orchard, from a 6000 gallon rainwater collection tank in central Arizona.
So far, we have operated it for one month on an every-other-day schedule for 12 or 24 minutes at a time, plus several manual cycles while setting it up to replace the old vertical, sump-pump unit that failed in similar service every 12-18 months. I will update once we pass that period.

Please note this pump has an installation requirement that it must be tilted by 15° or more from the horizontal for proper bearing lubrication, which is the angle we have it operating at now. This implies a certain amount of water will not be able to be withdrawn from my, or similar, tank installations, however we have years of experience using these types of well pumps with the same motor in other shallow-angle, potable water "pressure pump" service. It should not be run dry. It has a sturdy 3 wire, 230 V motor similar to that of more expensive pumps, and it DOES NOT require a starter box for operation. Just connect it to an appropriately sized motor-starting relay (we use a 230 V timer with 14 day settings and a 2 HP motor rating, which is overkill for this unit.) and it will operate. Make sure you seal the wire connections well, with an appropriate, wet-environment rated sealant.

It has been over 2 years in service and been operated in water temperatures from near freezing to 130°F and this pump is still chugging along nicely. Being in an outdoor tank in Tucson Arizona, this pump has on at least a couple of occasions been turned on for the 24 minutes (Twenty four minutes is my standard cycle every other day for the entire 2+ years, plus about one manual operation per month for about 10-15 minutes while all emitter heads are checked for flow.) when the water level was so low the pump wasn't able to pick up any water. So far it has proven to be highly reliable.

I have several rental properties that have septic systems. I have tried 2 other effluent pumps but the Little Giant is the best. It is constructed in 2 halves. The motor is on the bottom and the pump is on the top. The motor holds up very well but the pump part wears out. Had to return 2 but that was the exception to the rule. I recommend it.

Hard to know what is happening down in a well. All I know is that volume and pressure are quite satisfactory.

My needs were immediate for this item.
The deep well pump arrived on-time and well packaged, description was spot on, initial test before installation went fine.
Installation was fast (as I had done this before) with the help of a friend and has worked flawlessly since.

Originally received the wrong pump in the right box - called Amazon and in less than three days I had the right pump and sending back the old one was painless - Thanks
