Construction Standards

Materials and Workmanship Standards

Building codes must be followed when you are installing a new system or even just repairing an existing one. The materials used in your system should meet or exceed the appropriate standards and codes and be installed according to the manufacturers’ recommendations.

Doing the Job Right

Proper materials and workmanship are essential for maintaining a safe and reliable water system. For example, it is important to select materials for their pressure class or corrosion-resistant qualities, and to ensure that these materials are installed in accordance with the manufacturers’ standards by qualified installers or contractors.

Pipe diameter, threads, wall thickness, pressure class, corrosion protection, hoop stress, buried depth, surge protection, thrust restraint, pipe bedding, and jointing should all be considered when choosing building materials.

For instance, copper pipes can stand up to compression fitting and solder, but the “glue” type of solvent welding cannot be used on them. On the other hand, PVC and CPVC can be joined with solvent welding and compression fittings, but not with soldering.

As you can see, there are specific standards that materials and products must meet for different uses. When choosing materials, always refer to local building or plumbing codes, and look for designations such as ANSI, ASME, ASSE, ASTM, AWWA, BSI, CSA, DIN, IAOMO, ISO, NSF, and UL.
