The simple solution is to dig up the insulation run the pipes along the top of the ceiling drywall ie just above the ceiling rather than just below it and put the insulation back on top of them which puts them on the warm side of the insulation inside the home thermally speaking also to be a lot more careful when hiring plumbers.
Run water pipes in the attic ontario.
Ideally in the attic you would want to run the pipe as close to the ceiling as possible below the insulation.
When running pipe from a slab to an attic use cross linked polyethylene tubing or pex instead of copper.
To keep pipes from rattling line the holes with felt or use wood shims.
Pex is semi flexible which allows for long continuous runs through joists and studs.
This system uses more tubing but is fast and only requires two connections.
When water is running and is then suddenly turned off the rushing liquid has no place to go and slams against the shut off valve.
If notches are needed make them as small as possible.
They weaken the framing member.

With the home run system you install a manifold in the utility room or some area that s close to the main water line and water heater and run a separate pex tube to each fixture as shown above.
Cedric in your climate plumbing pipes can be installed in an attic as long as the pipes are installed under the insulation layer.
Besides being alarming water hammer can potentially damage joints and connections in the water pipe itself.
The loud thudding sound that follows is known as a water hammer.
I suppose you don t have freezing issues in fl but if you run it above the insulation the water in the pex will heat up more than if it is run close to the ceiling.
Slip a shim under the pipe and tap in until it is firmly in place but not tight to allow for expansion.
My plan is to run pex thru the attic below the insulation.
One at the manifold and another at the fixture end.
Need to get a hot water line from one end of the house to the other in a ranch with a concrete slab.
If possible run it under the attic insulation for an added layer of protection.
Whenever possible run pipes through holes in the center of framing members.
It wouldn t hurt to insulate the pipes with foam pipe insulation before the pipes are buried needless to say if you find the work daunting you should call a plumber.
It is also important to run the pipe as low in the attic as possible to provide heat from the ceiling below.
