My hot water pipe in my ceiling started to leak. The plumber came and said it is because it shouldn't be mounted to a piece of wood due to the hot water pump moving it around. The mount is probably in incorrect term, but it is holding the pipe up so it doesn't sag. His claim was that over time it would create the leak. Seemed legit, but now the pipe is sagging and then like eight feet away it is mounted to another piece of wood. This doesn't seem right and I feel like this will cause more movement and more damage down the road quickly. If he is right, then shouldn't the other mount be removed? if that gets removed the weight will droop way down and seemingly could cause damage. What should I do?
