In this 40 year old house, I've never had water hammer problems. Now I have a problem with one old Mansfield toilet. When the float rises to the top, water very slowly stops flowing. After the valve finally shuts, there is a one-second loud vibration. It seems to be coming from the pipes inside the wall, not from the tank or bowl. I added a small water hammer arrestor after the toilet manual shutoff and it didn't help or change this problem. No other fixtures in the house cause noise. The house has copper pipes (not PEX) and a submerged pump putting out 55PSI. There is also an expansion tank on the well output, so the pressure is relatively constant.
What are your thoughts on debugging and fixing this?
Thank you.
