"Hi"Im new here.This is a complicated post to explain,but here goes.
I have a dug well 18 ft,approx 80 ft from my mobile home.I have a jet pump in bathroom.This past few months,(after coming home one day),i turned pump on .(i always turn pump off when i go away for a few days).When i turned pump on,it ran,built up pressure,stopped and then ,after about 15 sec,started up again,built pressure to 40 lbs,shut off,and started this over and over till i shut it off.When i turn it on,the water is "right there" seems like and no problem,then it shuts off after i use what i need,and then starts up again. Its not muddy .
If it runs like this on /off a few times then it seems to get "air" in the system ,and will run ,about 3 min trying to get water and finally does,after a lot of air comes from the taps,and a large "whooosh",then all is good again.
As i say,if i use it to just run a bit and not cycle too often,its ok,but if it cycles too often then it loses the water ,and after blows out air ,then it ok....well cycling
If it was my foot valve i would lose all my water back in the well...and it wouldnt be able to draw it up all that way ,,would it? I see no where there is an underground leak,no wet spots on the lawn where pipe is buried.This happened while i was away for a few days . Sorry for the long post.
The pump is about 2 years old.The foot valve in well and pipes are about 12 years old.I checked air in my tank,,its 18 lbs and the shut off pressure is 40 ..do it need more air?
Thank you
