Frequently Asked Questions
Most Oatey pipe supports are suitable for both hot and cold water applications, but you must verify the temperature rating. Cold water lines operate at lower temperatures and have minimal thermal expansion, while hot water lines can reach 140°F-180°F and experience more movement. Always select pipe supports rated for your system's maximum operating temperature.
What is the difference between pipe clamps and pipe hangers?
Pipe clamps secure pipes directly to walls, floors, or ceilings using a clamping mechanism that wraps around the pipe. Pipe hangers suspend pipes from overhead structures using hooks, rods, or straps. Both serve to support pipes, but hangers are typically used for horizontal runs suspended from above, while clamps are used for securing pipes to solid surfaces.
How far apart should I put the pipe supports?
The spacing between pipe supports depends on several variables: pipe size, pipe material, and changes in direction. It is always best to check with your local building officials for new installation applications. As a general guideline, most building codes require support spacing of 4 feet for horizontal PVC pipes and 6 feet for copper pipes, but these requirements vary by jurisdiction. You can also reach out to Oatey's technical customer service department for assistance when completing a repair project.
Are any of the plastic pipe support clamps approved for use with hydronic systems?
Yes. All Oatey plastic pipe supports are approved for hydronic heating applications, but you must confirm the maximum temperature that the pipes will reach when in use.
Is a plastic hanger strap approved for supporting pipes?
No. A plastic hanger strap should only be used for temporary or non-load bearing applications. It can also be used as mid-level strapping where required by code, but it is not approved as the primary support for load-bearing pipe installations. For permanent pipe support, use approved pipe clamps, brackets, or metal hangers.
Can pipe support products help stop the banging sounds in water lines when the washing machine is operating and or the toilets flush?
Yes. Banging sounds are generated when a quick closing valve shuts off, this creates water
hammer. Washing machines, ice makers, single lever faucets and toilet fill valves are all considered to be quick closing. Water hammer will expose any loose pipes throughout the home and create banging sounds. If you locate the loose pipe(s) and secure them with the appropriate strap or hanger, you will be able to reduce or stop the banging sounds.
Are there any pipe support products that will insulate water lines passing through HVAC supply or return ducts?
No. The installation of water lines in/or through HVAC supply or return ducts is not approved in the majority of municipalities. Before attempting this application, we recommend that you reach out to your local code enforcement officials for their approval.
Are there any pipe support products that will support pipes hanging below the joist?
The Copper and Steel Pipe Hooks, Copper Plated Milford Hangers and CTS J-Hooks are all capable supporting pipes that hang down below the Joist or finished surfaces.
