I just moved into a house that has a well. I have noticed that my sump pump tends to run once or twice a day. It appears the water going into the sump is coming from the drain tile that runs closest to the well. It has been very dry and we haven't had rain for weeks. I am suspecting that the water line from the well too the house basement may possibly have a leak. Is there anyway to test or verify this?

Ok, heres the deal. I went to my moms house today to change a shut-off valve for outdoor water. I turned off the main water supply b/c no other shutoff is present. They have a 20gl pressure tank in the basement and the well is outside. I turned the water back on and we used water outside for approx 2 hours...My little brother took a shower but the water stopped and then started again about 2 mins later. I went back home and my mom got ahold of me saying "we have no water"......The pressure tank was empty but still read 48psi.....My mom also said that every few minutes the lights would dim. I went over there to see if i could find an answer only to find that my step dad wants to be lazy and ignorant and just pay money to have someone come out and check it out....She runs a daycare and needs it fixed asap...Can anyone help me fast before she goes and pays someone $$$$$ to fix something that may only cost a few dollars and is something i can do. HELP!
