A small leak under well water tank control
I have a well water tank system under the name Well-X-Trol. This was install new in 2005. There is a control box and a presure gauage on top of the pipe coming from outside well to the blue tank insides. I noticed only recently that there is a very small leak from the outlet under the control box. (Not from the pressure release valve under the pressure gauge). Is this an indication of some major problem or is it a small job that one can fix it? I also notice some rust inside the bottom of the presure gauge. Any help would be very much appreciated.
