Over the last month or two we have developed a loud vibration type sound that I finally was able to trace to where the water service comes into the house in the basement. I checked to be sure that the valve was turned all the way on but that didn't help. It seems to only occur when there is a water draw in the house like a shower running or the washer is on. What could be causing this and what would need to be done to correct it? Is there potential for something serious to happen like a pipe joint giving way or anything like that? Trying to figure out what I'm getting into by calling a plumber out-funds are a bit tight right now so I don't want to get hit with a huge bill that I don't have to have right now. (Although the sound really gets on our nerves sometimes so I may have to bite the bullet anyway) thanks
