•  It is not recommended to put a joint in concrete.
•  Pipe spacing is typically 12" on center for concrete slabs, and 8" on center between floor joists.
•  Use SharkBite Foam Insulation Installation Clips, Wire Mesh Installation Clips, or Subfloor Staples to secure the 
PEX during installation.
•  SharkBite 1/2" PEX has a 5" minimum bend radius.
•  Pressure test the system with air at 80 psi prior to pouring concrete.
•  Ensure that the loop lengths are specified appropriately to avoid excess heat loss. In most systems, the 
maximum length per loop should be 250'.
•  Protect the tubing with non-metallic sleeves when entering or exiting the concrete slab.
