i emptied out the tank when i replaced the Gauge. It took multiple pump on /off to reach 60 PSI after i installed the new Gauge and turned on the power.
The pump doesn't start if I don't use the water. What i noticed that when i do use water and pressure drops ( about 5 to 10 PSI), the pump starts and does it usual start/stop about for a minute until it reaches 60 and than stays off...
Your description of the pump starting when the pressure drops when you use water and the pressure drops 5 to 10 psi doesn't make any sense if you have a pressure switch that is operating between 38 and 60 psi as you have described. If it stops at 60 psi it shouldn't start until the pressure drops to 36 psi.
To help us all understand what is happening, please take a piece of paper and write down the actual pressure of each event (each pump start and each pump stop) as observed on the gauge, and the clock time in minutes and seconds for each event.
Your report that the pump doesn't start if you don't use any water says that you don't have a leak in the supply pipe or the check valve.
Please describe the "multiple pump on/off to reach 60 psi". Are the on/off intervals in the range of 5 seconds or less? What are the pressure readings when this "multiple on/off" occurs? If it is a rapid cycling (a few seconds per cycle) then the tank is almost certainly waterlogged. I find that very unexpected if indeed the tank was emptied when you replaced the gauge.
The tank is not necessarily empty when the pressure is zero, especially if it has been waterlogged. I suggest that you try again to empty the tank using the following procedure.
1. Shut off the power.
2. Open a faucet and leave it open.
3. Apply air pressure to the "tire stem" on the top of the tank, adding air to raise the pressure to 36 psi as measured by a tire gauge.
4. Rock the tank back and forth to verify that the tank is indeed empty. It should have absolutely no water in it. It should feel light and empty.
5. After ensuring that the tank is empty, close the faucet and start the pump.
