Re: pressure tank rebuild

quote kirkp:

Only other issue I’m having is that when I got it all apart I found that the spring that goes under the diaphragm under the plunger was collapsed. Looking at it and part of the wire was corroded and easily broke off. Found this strange considering the interior of the tank is very clean. I would think that if the spring was corroded the inside of the tank would be toast as well.

This is a common problem. I think that when these tanks get left out in the rain, water gets into the pump chamber through the aluminum pushbutton, and gets trapped in there with nowhere to go. Then, that water sits in the chamber for a long, long time. The diaphragm seals the water in the chamber, and keeps it separated from main tank body.
