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.
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.
Insulating Pipe Clamps
DuoFit Pipes Clamps
There are several variables involved with the answer to this question; size of pipe, pipe material and changes in direction. It is always best to check with your local building officials for new installation applications, but you can also reach out to our customer service department for assistance when completing a repair project.
Yes. All Oatey plastic pipe supports are approved for this application, but you should    confirm the maximum temperature that the pipes will reach when in use. With the    exception of the DuoFit Pipe Clamps rated from 0°F to 230°F and the Stand-Off Half Clamps rated from -60°F to 160°F, all other Oatey plastic straps are rated from 0°F to 180°F.
Metal Stud Insulating Pipe Clamps. These are available for ½”, ¾” and 1” pipe sizes.
No. Plastic hanger strap should only be used for temporary or non-load bearing applications. It can also be used as a mid-level strapping where required by code.
CTS is an acronym for Copper Tube Size. Oatey supports are sized based on CTS. For example; ½” CTS piping used in plumbing applications actually has a 5/8” outside diameter (OD), but is referred to as ½” pipe. ¾” CTS piping used in same application has a 7/8” OD, but is referred to as ¾” pipe. Pipe classified as IPS or Iron Pipe Size will have larger ODs than CTS and HVAC pipe ODs are smaller than CTS.
Yes. Any AAV can malfunction or not operate properly because it is a mechanical device. Signs of that the Sure-Vent is not operating as intended, are foul odors. If you smell foul odors (sewer smell) near a plumbing fixture which has a Sure-Vent installed, this means the Sure-Vent is not closing properly to create a positive seal and should be replaced. Some individuals relate slow drains to the Sure-Vent not operating properly. The Sure-Vent is not the issue, the slow drain is related to a partial blockage within the drain itself. A partially blocked drain will fill with water when the fixture is draining, and the Sure-Vent recognizes the positive pressure from the restriction and stays in closed position to stop backflow out of the Sure-Vent. You should have your drain cleaned when this occurs.
