Neal Lewis Posted October 27, 2009 Report Share Posted October 27, 2009 Quick question. How far can a single pipe jet type well pump lift water from underground? And can someone explain exactly what the foot valve does? Thanks Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted October 27, 2009 Report Share Posted October 27, 2009 Quick question. How far can a single pipe jet type well pump lift water from underground? It depends on the elevation above sea level, but the industry standard is 25'. And can someone explain exactly what the foot valve does?It's a simple check valve above an intake strainer. When the pump is on, suction lifts the valve open. When the pump shuts off, it keeps the water in the suction line from flowing out, which would result in loss of prime.

Thanks Hi, This is my favorite place for learning stuff about private water supply systems. http://www.purdue.edu/envirosoft/private/src/main.htm ONE TEAM - ONE FIGHT!!!

Neal Lewis Posted October 27, 2009 Author Report Share Posted October 27, 2009 Thanks, somebody told me his well was 125 feet deep using a jet pump. I was pretty sure he was wrong. Quote Link to comment Share on other sites More sharing options...

It could have been drilled that deep, but the intake isn't set that far down. Was there an ultraviolet or chlorine injector? I can't remember seeing a single-line pump system without one.

Les Posted October 27, 2009 Report Share Posted October 27, 2009 Guys there are deep well and shallow well jet pumps. It seems the laws of physics limit how far a "pump" can suck water upward and how far a pump can push water up. Kinda like saying your pickup truck can pull 3tons.

Yes - a single-line pump jet pump is for a shallow well. A dual-line jet pump is suitable for a much deeper well. He was specifically asking about a single-line jet pump.

Chad Fabry Posted October 28, 2009 Report Share Posted October 28, 2009 Was there an ultraviolet or chlorine injector? I can't remember seeing a single-line pump system without one. Most shallow wells that I see don't have any treatment systems. I can certainly see the increased probability for contamination in a shallow system but because it's shallow doesn't mean it must have a treatment system. The hole that I pull water from is only about 8 feet deep; according to Cornell, I should be bottling the stuff. Quote Link to comment Share on other sites More sharing options...
Neal Lewis Posted October 28, 2009 Author Report Share Posted October 28, 2009 There was no UV system, just a softener. This house is about 100 feet from a glacially formed lake that's supposed to be very clean. Quote Link to comment Share on other sites More sharing options...
