Sand point help

[GSB Ice Man]

Well, I put a point in and got water at 24'. Burried the point about 6' into it and had about 5'6" of water in the pipe. I used 42" point and 2" pipe. I hooked a 1.5 h.p. Gould pump, and it only pulsated outa the hose. I have heard once the water level gets past 25', the gravity resistance is too hard for a pump to pull. Whats everyone's thoughts on this??

Most shallow well pumps are only good for 25 ft so you should be fine there I am down 19 ft and it runs really good check your out put pressure on your pump also you may have a air leak some place and this could cause problems.

I'm not a pro with these pumps but I have put several in with out any problems.

do you have a air bladder tank hooked up that could be some of the problem but I doubt it.

Your close to what a pump can lift.

Like Elwood said if you don't have a tank and are using a pressure switch the pump will turn on and off(cycle) about every second.

Your information on maximum lift is correct. At about 30' or so, it takes almost 15 pounds of force to pull water up the column, and at sea level we have only 14.7 PSI of air to work with, less here at 1000'....see where this is going?. Assuming you have no air leaks in your plumbing, your pump is probably cavitating due to the depth of the well. Cavitation is an effect where small bubbles literally explode in the water due to the low pressure and the agitation caused by the pump components. Even if you are successful in pulling water from that depth, the minor cavitation will eventually destroy the pump. Time to shop for a pumping system designed for wells in the 30' to 50' range.

Get yourself a pitcher pump, hand pump, and see if you can pump water with that. if you can pump water by hand you should be able to pump it mechanically. why a 1.5 hp pump? also make sure it is a jet pump and not a centrifugal (sprinkler) pump? it was mentioned to try a pump with a deeper pumping level. to do this you will need at least a 2 inch casing and have to use a deep well jet pump that will require installing a packer inside the casing with the nozzle and venturi down in the well. its not so much the pump or horsepower of the pump, but the distance of the venturi in relation to the static water level in the casing. the 25 foot is pretty much the limit for a shallow well pump. and even at 25 feet dont expect much.

Well,

I tried something different on the point today. We moved to the basement and cut a hole in the sump pale basket. I then used a shop vac and sucked the sand out to a depth of 16'---I know it sounds weird but the neighbor told me to try it. I gained an additional 8' by going to the basement from outside. It pumps now, had 2- 3/4" garden hoses runnning for about a half hour.

I have water at 17' and burried the point farther with 5'6" of water in the pipe.
