I have an FP4222J-08 pump that is going out....won't pump past 38psi. At this point I am just going to replace the pump as I quite sure its around 20 years old. I wanted to know what my replacement options are. The new model number is fp4222-08. Is this just the pump without the jet adapter? I also would like to know what options I have for upgrading to a 1HP pump. I don't know the depth of my well, so all I have to go on is the pump I have now.
