Home is 3 years new (built during the peak of insanity here with home building). The shower handle fixture slides around the wall when I turn it on....I took it apart, you can see in the hole that the plastic pipes coming up from the floor in the wall are not secured to anything so they move freely when i touch them. there is no other access to the pipes other than thru this hole behind the handle. Other than it being annoying to have the handle slide around, do i need to worry that the pipes will not take this kind of movement well, and eventually break? Thanks for any input.
