Question:

Have I damaged the water supply pipes behind the wall to the toilet?

While trying to remove the water supply shut-off valve to the toilet, the copper pipe from the wall began to rotate. I was worried I may have damaged the pipes behind the wall. However, I checked the water meter after an hour of no water usage, and it doesn‘t look like anything is leaking. I‘m just worried I may have caused something to happen in the long-run though.

Answer:

If it is copper with either a compression fitting on the valve or soldered on valve you may have just twisted the pipe a little or if you were heating the valve you may have heated the joint in the wall which has resealed both are probabably ok but a small drip in the wall would not show up on the water meter the only thing to do is keep a close eye on both sides of the wall for signs of dampnessoropen the wall to inspect.
you don't need to replace the shocks but you do have to drop the bottom mount on the shock to replace the coils, so your half way there i would replace them if you have alot of miles and they never been replaced.
Most likely it is a copper adapter to a pex or compression fitting. It is cheaper to fix drywall 12X12 hole than it is to fix a flooded home, I'd cut the drywall and replace the entire assembly and secure it well to the framing, no more worries!
Are you sure that the piece of pipe that began to rotate is copper or is it brass? 1- If it is brass, then you turn off the water supply, (Main). 2- Open all your faucets and when they slow down to dripping, disconnect your tank supply and turn that piece of brass all the the way out. 3- Get some teflon tape (plumbing supply - local home center. 4- Wrap the threads three or four turns, replace the (threaded nipple) and tighten it. 5- Reassemble everything tight, turn off the faucets and turn the water back on. 6- This should take care of any possible leaks you may not have seen the first time (and any damage that might have done [small dripping leak] that would have shown up maybe years down the line). Good Luck ! ! !
