Our house was built in 1986. It has a Am Standard wall hung tank type elongated toilet in one bathroom. When someone sits on it there is a creaking noise from the wall. It can be heard throughout the house. Here in extremely dry Arizona wood gets very dried out. It appears that it will be necessary to tear into the wall to fix it. In that case I would also like to raise it to comfort/chair/ADA height.
Has anyone else had this situation? Any advice?
