First,
Thank you for offering this forum. It is great that there is a community available for us to find help/solutions to our problems.
I am a first time domestic well user, having purchased this house a year ago, I don't have any experience with wells.
My holding tank became water-logged a couple of weeks ago. I had a local company come out to fix it (so I could also watch and do it myself next time).
They drained the tank, etc, but also installed a bleeder valve and back-flow protector at the well head.
While they were there, I asked the tech about the pressure dropping below 20 pounds (even down to 10 pounds at times) when I run the sprinklers and fill the pool (running the water for a long period of time).
He said that the pump should always keep a certain amount of pressure going regardless of the pressure gague on the holding tank, and that the only reason the flow should drop that low is if the water level dropped down to the pump.
He said the pump could be wearing out and suggested that I may want to replace it before it fails.
I did my own experimenting and found the following:
I ran the water continuously and checked the level of the water in the well with a well water line tester (with the beep when it hits water). I also checked the depth of the well.
The well is 156 feet deep and the water level never dropped below 26 feet even though the pressure in the holding tank dropped down to 20 lbs. I pulled the line a couple of times and wiped it dry just to be sure it wasn't picking up residue and beeping from that.
After reading several posts on this site, my thoery is that the pump probably has a much lower flow/pumping capacity and once the holding tank drops to a certain level, I am getting just the flow from the pump. I still need to do a test to see what the pump is actually pumping per minute, but I wanted to see if anyone could verify that that is probably the issue.
My only concern was that he said the pressure should never fall that low on the holding tank. I don't want to spend a ton of money on a new pump if I just need to adjust my sprinklers and just fill the pool with a 1/3 open hose valve instead of higher.
Thanks for any feedback!
David
