I have noticed some fluctuations recently in water pressure recently and as we are preparing to sell the place I figured I have our well guy make a service call. Glad i did. I’m pretty squared away on these but would have been chasing my tail on this one. He, apparently wanting to make me feel bad, goes into the well house for about 30 sec and comes out. He says, “got it.” I say, “You *****.” It was the 1/4” galv ****** to the pressure-trol. I not sure how it worked at all. Replaced the control and put in a brass ****** and we are good.
