JUMP TO FULL CODE CHAPTER
Low temperature piping for embedment in concrete or gypsum materials shall be as indicated in Table M2101.1.
Piping joints that are embedded, other than those in Section M2103.3, shall comply with the following requirements:
- Cross-linked polyethylene (PEX) tubing shall be installed in accordance with the manufacturer's instructions.
- Polyethylene tubing shall be installed with heat-fusion joints.
- Polypropylene (PP) tubing shall be installed in accordance with the manufacturer's instructions.
- Raised temperature polyethylene (PE-RT) shall be installed in accordance with the manufacturer's instructions.
Joints between raised temperature polyethylene tubing and fittings shall conform to Sections M2104.3.1 through M2104.3.3. Mechanical joints shall be installed in accordance with the manufacturer's instructions.
Where compression-type fittings include inserts and ferrules or O-rings, the fittings shall be installed without omitting such inserts and ferrules or O-rings.
Solder joints in a metal pipe shall not occur within 18 inches (457 mm) of a transition from such metal pipe to PE-RT pipe.
PE-RT insert fittings shall be installed in accordance with the manufacturer's instructions.
Joints between polyethylene/aluminum/polyethylene pressure pipe and fittings shall conform to Sections M2104.4.1 and M2104.4.2. Mechanical joints shall be installed in accordance with the manufacturer's instructions.
Where compression-type fittings include inserts and ferrules or O-rings, the fittings shall be installed without omitting such inserts and ferrules or O-rings.
Solder joints in a metal pipe shall not occur within 18 inches (457 mm) of a transition from such metal pipe to PE-AL-PE pipe.
