i am on a well and my water pressure never seems to be real strong but not real bad either. after flushing the toilet or showering the well will turn on and go up to 55psi and shut off. after about 30 minutes i noticed it reading at 40psi... when i get up in the morning it reads 28psi. my neighbor said it should hold at 55 or drop just a little bit and the bladders bad but i dont agree, when my well pump was installed 7 yrs ago the guy wrote 28psi on my tank. i think thats what its supposed to read and my pressure is just because i have a very deep well. anyone know whos right ?
