We have a bored well and have put in a new pumping system about 9 years ago. Pump comes on every 5 mins. runs for about 15 to 20 seconds and the psi goes up to around 40 - 45...then it slowing goes back down to around 30 or every 27 psi and the pump comes back on...I turned off the water near the pump to see if it would continue to do this if there was no water going to the house. Crawled around under the house to see if there was some leak...or something... and there was a leak that was causing a trickle of water. Once this leak is fixed, will all be o.k...or do I need to have my pump serviced since I believe that the pump/pressure switch was coming on every 5 mins. or so for over 24 to 48 hours???
