One at the manifold and another at the fixture end.
Run water pipes in the attic ontario.
Slip a shim under the pipe and tap in until it is firmly in place but not tight to allow for expansion.
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.
Water line would run over the top of the 2x4 bottom truss cord and i would create a tent over pipe so there was no.
No interior walls to use either.
If possible run it under the attic insulation for an added layer of protection.
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.
The loud thudding sound that follows is known as a water hammer.
When running pipe from a slab to an attic use cross linked polyethylene tubing or pex instead of copper.
Pex is semi flexible which allows for long continuous runs through joists and studs.

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.
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.
Ideally in the attic you would want to run the pipe as close to the ceiling as possible below the insulation.
Whenever possible run pipes through holes in the center of framing members.
My plan is to run pex thru the attic below the insulation.
To keep pipes from rattling line the holes with felt or use wood shims.
Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.
They weaken the framing member.
It is also important to run the pipe as low in the attic as possible to provide heat from the ceiling below.
This system uses more tubing but is fast and only requires two connections.
Besides being alarming water hammer can potentially damage joints and connections in the water pipe itself.
