I'm having an issue with a 2nd floor toilet and wondering if anyone has come across something similar?
When hot water is draining from the sink or bath tub in the room a clicking noise can be heard and within 45 seconds the toilet lifts approximately 1/4 inch off of the floor. And will move when touched. About 10 minutes after the hot water is turned off it settles back into its normal position and is secure to the floor. There is a powder room directly under the main bathroom and draining hot water from that sink on the 1st floor will also cause the 2nd floor toilet to unseat. No other hot water sources in the house, out of this one direct drainage line, cause the problem to occur.
I have verified that the problem does not occur when hot water is running with a plug in when cold water is draining. It is definitely related to hot water draining. And that the toilet will re-seat quickly if cold water is drained immediately following hot.
I had originally suspected the issue might be caused by the hot water tank and mixing valve but they appear to be fine and the problem is not when the water is running, but when draining.
Water temperatures are normal, approx 135 degrees for straight hot water,
The water in the toilet bowl and storage are consistently cold.
The toilet is also properly secured to the flange.
Appreciate any thoughts from the forum.

The stack is expanding from the heat and pushing up the toilet. Likely the stack is plastic, either ABS or PVC and the toilet is very close to the stack. The toilet flange is not secured to the floor.

the expansion of the stack must be controlled
do NOT bolt down the flange as said expansion WILL break something
my first solution: reduce the water temperature to 115-120 degree F.
second solution: the stack needs an 'expansion joint'
placed into stack below toilet connection and stack 'anchored' above joint
see: [www.bing.com]
after expansion is controlled, THEN bolt down the flange
