I have had a sand point that I use for lawn irrigation for over 20 years. It is hooked up to a 1 1/2 horse sprinkler pump and runs from 5 to 7 spinklers heads at a time. I used 1 1/4 pipe and it is down about 23 feet.
I have had no problems with the system in those 20 years. This year I am getting much less water out of the well than I have in years past. There is not enough water coming out to even pop up some of the spinkler heads. When I first put the well in I was told I should be able to put a garden hose down the well, run the water and no water should come back up. 20 years ago when I did this, no water came back up the pipe. The well would take as much water as I could put into it. This year water does come back up the pipe. I am not sure if my well has started to go dry or if the sand point is clogged. I was leaning toward the theory that the sand point has just become clogged or has started to fall apart after 20 years and that is why water comes back up the pipe when I run water down the pipe from the garden hose. It has no where to go because the screen is clogged or fallen apart.
How long does the average sand point last? Do they deteriorate over time?
I lowered a cotton string down the well with a weight on the end of it. When it hit bottom I pulled it up and had just over 3 feet of wet string, that tells me I am in 3 feet of water.
Any thoughts on if the sand point is clogged or the well is going dry. I have two neighbors one about 150 feet away who has a two inch sand point and his is working just fine.
Any thoughts or ideas on what may be wrong would be great.
Thanks.
