• 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.
