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.

No. Sure-Vent must be installed as close to vertical as possible. You cannot have the Sure-Vent tilted more than 15° from side to side, otherwise it will not operate properly.

Negative pressure in a DWV is created when a drain or fixture has fluids flowing through them, this is why a vent is required. Without a vent the water would flow very slowly or not at all. Example: stick a straw in a glass of water and before you remove the straw, put you thumb over the top of the straw. When you remove the straw, the water stays in the straw because there is no vent. When you remove your thumb, the water flows out of the straw because you have a vent. The Sure-Vent allows each plumbing fixture and drain to receive the needed air to drain properly. Positive pressure is present when the city sewers are relieving pressure that is designed to push back up through the building sewer and eventually out of the roof vent on your home or building. While this positive pressure is being released and your plumbing fixtures and or drains are not being used, the Sure-Vent will remain closed. This is important because if the Sure-Vent did not protect you from positive pressure, your home would fill up with foul odors.

Yes, with exceptions. Remember that septic systems build up positive pressure as the organic waste breaks down in the tank, this creates positive pressure. This positive pressure can affect the performance of the Sure-Vent, and you may have to add a vent on the inlet side of the septic tank if this happens. The vent on the septic tank is most commonly recognized as a pipe that looks like a candy cane.

Yes, with exceptions. When the RV is stationary, the Sure-Vent will properly vent the drains for the kitchen and bathroom. If the RV is in motion and depending on how the DWV system was assembled from the factory, positive pressure could stop the Sure-Vent from opening. 

You must first check with your local building officials to confirm that the Sure-Vent installation you are attempting is recognized as an approved application. If your application is approved under the guidelines of the plumbing code in your area, a Sure-Vent can be used to vent any plumbing fixture and or floor drain.
