Pumps, Wells, Tanks, Controls / Pressure goes from bad to worse after adjustment
« on: April 19, 2016, 08:26:59 PM »
I have submersible pump with pressure tank. I've had pretty low water pressure in upstairs for quite some time (years!). In an attempt to "improve" things, I adjusted the tank so it clicks on at 30 and clicks off at 50. I also pumped air in the tank to bring it up to 28 pounds. It seemed to improve things for about a week, but now things are worse than they were before. I noticed a few symptoms that I thought might help someone with experience diagnose my issue (these symptoms were occurring before I adjusted it -- I noticed them while trying to adjust it):
- when the pressure reaches its cut off point and the pump shuts off, the pressure drops somewhere between 5 and 10 pounds before it stabilizes. It does stabilize though.
- I notice that the pressure needle is quite jumpy when it reaches the cut-on point too.
- when the pressure tank is filling, the *rate* at which the pressure climbs also goes up
- when the water pump kicks off, the tubing that goes to the pump shakes back and forth significantly and makes a noise that can be heard upstairs
- our water does have some sand in it; it has had for years.
- there is a check valve on the pump side of the pressure tank (in the basement, near the pressure tank).
- I don't think that the pressure tank is water logged. It seems to have maintained its pressure after I filled it.
Any ideas? Thanks in advance!
