I recently started having water pressure issues. Off the bat I replaced the pressure switch and cleaned out the tube it connects to. It still read 20 psi when I turned the breaker off, so new psi gauge. Cut the power back on and still reads 20 psi. I contacted the previous owner and he told me the pump had been replaced 27 years ago. Great, so I put a new pump in( submersible, 225’) I didn’t see any leaks in the poly pipe(all one piece) still not running enough pressure to turn a 30-50 switch off. So I pushed on the pressure tank(bladder, vertical) and it was very heavy, so I replaced it(water logged) I still am not getting over 20 psi of pressure and I’m only getting like 15 psi with a faucet in the house on... any ideas at all?
