Greetings everyone. I replaced my pressure switch on my shallow well set up this weekend as the contacts on the previous one were blackened from short cycling. After doing this, I drained the pressure tank of all water, pumped in enough air to make 28 psi per the 30/50 switch's requirement. I did not make any adjustments to the pressure cut on/ off controls. The well itself is 13 ft deep and the pump is located inside the well casing somewhere. It's at least 20 years old. I'm attaching a link to a video of it running. I can't tell if it sounds normal or not. Let me know what you guys think and thank you.
