Q: I plan to replace a 30 yer old pump that is at 200 ft. and lower the new pump to 250 ft in a 400 ft deep well. Will I need to a check valve mid way up as well as at the well head?
by Ken G from California on July 27, 2015
A: Most submersible deep well pumps include a built-in check valve at the discharge port of the pump and It is recommended that additional spring loaded in-line check valves be installed in the drop pipe @ 200ft intervals only.

Q: what parts are involved with submersible pumps that can fail and breakdown or if it doesn't work you just have to replace the entire pump?
by Sal from New York on January 22, 2014
A: When it comes to 2-wire deep well submersible pumps, the pump starting controls are located inside the pump. Any of these components can fail and cause the pump to become inoperable. By installing a 3-wire pump, those components would be located inside a CONTROL BOX, making repairs much easier when failure of these components are the cause of your pump not operating. Of course if the pump has failed due to burnt motor windings or some other cause, would would still need to pull and replace the pump, but you would have a better understanding of the pump status when the pump starting components are above ground as opposed to 50-500 feet or more, below ground.

Q: Hi Jim,
I have a well with 4 inch bore (pipe with 4" ID) and want to switch to a 4" submirsible pump. my question is with a 4" submirsible pump how much clearance do i need.
does the bore not need to be much larger then 4" otherwise how will the pump suck water if the will pipe walls are touching the pump.
by Javid A from California on January 06, 2014
A: Thank you for your interest in Water Pumps Direct. The actual pumps measure 3.90" in diameter and will fit inside a 4" ID well casing.

 Like the other recommended deep well pumps here, this pump is also made by Franklin Electric, a known and trusted brand with a long history of providing dependable pumps.
With the Little Giant name, you can expect a higher quality and longer lasting pump that also includes that Franklin Electric motor that you've come to know and love! And the ceramic bearing sleeve & stainless steel up-thrust washer will help to prevent excessive wear and provides added durability.

 Most Helpful Positive ReviewPump Functions As Expected
The pump arrived as planned. The only negative was that the wire connect kit had fallen out of the box in shipping, Install was simple as we replaced a franklin that had a motor problem. The new pump is working great, flow and pressure are better than the old pump. It is set at 111' in the well.
Pros: I'd Buy It Again Cons: Packaging Henry Recommends This Little Giant Product Was this review helpful? 10 |

Most Helpful Critical Review  Called Red Lion But But No Answer
Called several Red Liom numbers but no answer. Did not put the pump in for use as I was hesitant in doing so. I'll try again next year I have a Red Lion 220 vac, but would like to go with 110 vac pump. Water is at 180 ft and the pump would probably deliver but at what pressure ? would I need a holding tank can I use another 110 volt pump inline to get 50 psi. The pump I have now is at 230 ft and was originally at 300 ft.

It's A Great Pump
I took out a one horse and replaced it with a little giant half horse and it is just as strong as the one horse!

1/2 Hp 12 Gpm Hp Deep Well Submersible Pump (2-wire 115v) Little
This pump was installed and powered by an off grid system. The pump works great and it pressure's up on a 30/50 switch very nicely. We are very happy with the Little Giant,and we would give this pump a thumbs up for anyone that lives off grid.

Little Giant Well Pump
This unit is twice as fast at building pressure as compared to the Goulds pump it replaced and quieter as well. It also came with heat shrink sleeves with sealant and wire butt connectors which I soldered. So far, so good!
I also understand that this pump comes with a Franklin motor.

Excellent Pump
I installed this pump with a 10 GPM Dole valve in a very shallow well six days ago. It works much better than the jet pump it replaced.
