Whether securing or supporting a plumbing pipeline below the wall, ceiling or floor, pipe supports such as hangers, clamps, brackets, and hooks are essential to complete your DWV (drain, waste and vent) drainage, water-supply line, or hydronic-pipe applications properly.
Below, we explain why proper plumbing pipe supports are necessary. We also provide a complete overview of Oatey’s pipe support offering to ensure you choose the appropriate pipe support for your project.
Why proper pipe supports are necessary
- They keep piping systems secure: An improperly supported piping system could result in pipes crashing through a wall or down from a ceiling — potentially hurting someone, causing damage to the building, or both.
- They reduce pipe movement: Using pipe supports will help reduce noise in DWV systems or “water hammer” in water-supply systems.
Water hammer can be absorbed by any unsecured lines, resulting in partial-to-extreme movement — creating contact with adjacent surfaces. Pipes should be adequately supported and/or insulated to prevent touching any surrounding building materials. Pipes that are insufficiently secured will move and cause a knocking or vibrating sound when coupled with even the slightest amount of water hammer.
Choosing the right type of pipe support
To ensure the satisfactory operation of a piping system, carefully consider support location and type.
Plumbing codes require that all piping and the contents inside be supported so that the pipe maintains alignment and doesn’t sag. Plumbing codes also typically require hangers and strapping materials to be made of an approved material that will not promote galvanic action. Of course, they must also be of sufficient strength to support the pipes’ weight and contents.
Choosing the proper pipe support for a given piping system largely depends on the pipe material.
- Water-supply pipe is Copper Tube Size, commonly referred to as CTS.
- Gas and drain pipes are considered Iron Pipe Size, or IPS.
To break it down, a one-inch piece of copper or CPVC pipe is going to require a different hanger type and size than a comparable piece of gas pipe because of factors like wall thickness, diameter, and load (weight of the piping).
Once you consider all of the above, the choice of pipe support may ultimately be based on personal preference.
Oatey tip: Pipe supports are only as strong as whatever it is anchored to — wood or concrete. If not anchored correctly and securely to the wall or ceiling, how much weight the hanger can hold will not matter.
