New pressure pump cycles when reaches top pressure

[RiverbedRanch]

On my off-grid homestead, I'm using 1.5" PVC pipes to bring water into my pump house from my 2,400 gallon tanks. The pump and pressure tank are brand new. Got it all hooked up and turned it on. Pressure built up until it hit 60psi. Then the pump starts cycling on and off every second or less.
Tweaked the settings up and down trying to get it to switch off. Won't. I installed the pump at roughly the height of the top of the pressure tank (so it wouldn't short out if the underground pump house ever floods). So there's a good six feet of pipe between the pump and the pressure tank. Wondering if the pump has to be closer.... Wondering if the cycling could be due to air in the PVC pipes... at a loss.
Guidance would be appreciated!

Sounds like you need a check valve.

Valveman is always correct.

Was the empty pressure tank pre charged at 38 PSI? If the bladder is blown, pressing the pin on the schrader valve only air should come out, not water.

You may be right. I had one but didn't make room for it. In order to add it in, my piping will truly look like a bowl of spaghetti!

Yes, the tank was pre-charged. Though, the instructions on the pressure pump said to reduce it to 28psi, which I did. (Don't remember now if that was before or after turning on the pump for the first time).

Tank precharge should only be adjusted when there is no water pressure.

Precharge for 40/60 is 38, 30/50 is 28.
