Lightbulb Well pump turning on and off too frequently

This is my first time writing for help so thank you in advance to anybody that can help. My house has well water and I replaced the tank and components around the tank. Everything has been working for about a year fine until now whenever we use the water the pump turns on/off very frequently. The pressure goes from 60 down to 40 then turns on again. Will this mean I will have to replace the well pump? How often do you replace them? I think it was put in 12/01. Thanks to anyone that can help.

Sounds more like your pressure tank causing the problem. Turn the power to the pump off, completely drain the tank, and check the tank precharge. It should be 2 psi less than the pump cutin pressure. In your case, if the pump starts at 40 psi, there should be 38 psi in the tank. Add or remove air as necessary.
If water comes out of the air valve, it usually means that the bladder is bad.
Let us know what you find.

The problem could also be the check valve above your well pump. The pump comes on and pressurizes the line, but when the pump shuts off the water in the well head falls back into the well and the pressure in the tank drops. The regulator senses the pressure drop and turns the pump back on. I had mine replaced 5-6 years ago for just that reason. It cost about $100 then. You could do it yourself, but it might be a tough job if you have a deep well.

Lightbulb well tank pressure problem

I tried to drain my tank to check the pressure and have found very little water even in there. The pump is turning on/off very frequently when the water is in use. When I went to fill the tank back up again you can tell that very little water went in the tank and the pump turned off with a reading of about 53 on the pressure gauge. Can anyone help to figure out what's going on? Thanks for any help.

How much air was in the tank when you drained it? Shut the pump off and drain the tank again. This time, see if you can rock the tank a little and see if it still has water in it. I suspect the bladder is ruptured and the water is not draining out. If the water won't drain, you need a new tank.

Cool may have fixed the pressure problem

After draining the tank I tried to check the air control/pressure gauge. I replaced it and it seemed like it was clogged up with material (dirt+more?) The tank drained further as I losened up the gauge. Anyway there is a small screw to tighten and loosen the rate of air in the tank and that has seemed to do the trick. The pump is coming on now at a better rate again. Thanks to everyone that helped with ideas.
