Hello everyone. First time poster looking for some good advice on to solve a serious water hammer problem. I am just a home owner with zero technical knowledge when it come to plumbing. First, some information that may be helpful. Then again, it may not. I am just trying to anticipate what may be important to the equation.
I am on a well and we have a water softener in line right after the main line enters the house in the basement. The pressure tank is just before the softener and reads about 50 psi. I have heard the pipes in my wall bang very loudly in the middle of the night when the softener is cycling. I am not sure what part of the cycle it is on, but it takes place several hours after the regeneration starts and is near the end. Today, I did a manual regen and heard it again. It was so loud I thought the walls were falling down. None of the other appliances cause this problem. I have researched water hammer and think I understand what is likely happening. However, I would have thought that the shock wave would travel back down the line from the softener and be absorbed by the the pressure tank that is in line just before the softener, acting like a hammer arrestor. This obviously isnt the case. Any help anyone could offer is greatly appreciated.
