We bought our current house a year ago and upon moving in had a problem with our pressure tank, having to replace it. The other night I was taking a shower and in the middle of the shower I lost all pressure. This has happened a couple of times since then. I talked to the guy who replaced our pressure tank and he said it sounded like our well pump was going bad. I then went up to take a shower this evening and while the hot water was running, I turned on the hot water in an adjacent tub in the same bathroom and lost most of the pressure in the shower. As soon as I turned it off the pressure came back on. I then tried turning on the cold water in the shower and also in the bath tub. When I did this I had absolutely NO water in the shower. Again, turning off the tub restored the water to the shower. In my kids bathroom which is right next to mine (on the 2nd floor), if I turn on the shower and then turn on their sink, the shower does lose pressure but not as significantly as our bathroom. Of course, we're comparing a sink's output in my kids bath to the bathtub in our bath. A few months ago I put a water softener in and have not had any problems until a few days ago so I don't know if it's related to that or not. I've turned on the bypass switch on the softener and haven't noticed any difference. The guy who did our pressure tank now says it doesn't sound like the well pump after all but like we have a blockage somewhere in our plumbing. So, what are your thoughts on this? And, if it's a blockage, how can I tell where it is and get rid of it? Thanks!
