You can use one of our thread tapes or pipe joint compounds to complete this application. If you are using thread tape, wrap the male threads on the tail piece 2 or 3 times, and then screw the tail piece into the pop-up body. After the drain has been tested and found to be water tight, you can cut the excess thread tape off if desired. If you use pipe joint compound, only apply it to the male threads of the tail piece and wipe off excess after the drain has been tested.

Oatey offers a wide variety of covers that include supply line and stop covers, offset drain covers and P-trap covers. 


With the exception of the P9703 and P9703BG, all of our plastic tubular products come with the True Blue washer. The P9703 and P9703BG come with the polyethylene rigid washer. All brass tubular products come with a square cut rubber washer, which performs better on the chromed surfaces.  

  • True Blue is IAPMO listed.
  • True Blue won’t dry out or crack. This ensures long, leak-free protection.
  • True Blue has superior flex fatigue protection, which extends the life of the washer.
  • True Blue has advanced Thermoplastic Elastomer (TPE) properties. This allows the True Blue to retain its shape when the traditional polypropylene washer may not.
  • Overall; the Ultra flexible elastomer washer combined with the tapered design, provides the end user with ultimate leak protection.

An Air Gap product is designed to be installed in to the countertop in some municipalities when a dishwasher is being installed. The hose from the dishwasher will connect to the inlet side of the air gap, then a separate hose will be installed between the outlet side of the air gap and the disposal or dishwasher tail piece. Check with your local building officials before installing your dishwasher because air gaps are not required in ever municipality.

No. The S-Trap is not approved for any installations that require a plumbing permits and or inspections.

No. The Form-N-Fit is not approved for any installations that require a plumbing permits and or inspections. 

If you have a disposal installed in your kitchen sink, the dishwasher drain can be connected to the ¾” drain port designed into every residential disposal. If a disposal is not available for a drain connection, Oatey offers several styles of dishwasher branch tail pieces for this application. You can find these available tail pieces in category 15 in the Oatey catalog or on our website.

No. The polypropylene materials cannot be assembled with solvent cements, they have to be assembled with the slip nuts/washers.

Yes. The N.Y. Code and L.A. Code traps are designed to work for this application.

The most common tubular product sizes are 1¼” and 1½”. These sizes are available in brass and plastic tubular products. The trap adapter connection to the branch drain in the wall will determine the largest size of tubular product which can be connected with a slip nut and washer. This point of connection can also be reduced for 1¼” tubular assemblies, with a reducing washer and slip nut. Bathroom sink installations are normally completed with 1¼” tubular products, but 1½” tubular products will also work. Kitchen sink installations can only be completed with 1½” tubular products. 

Yes. Our brass tubular products are offered in three different thicknesses (gauges).

  • 17 gauge is the thickest, and is often referred to as commercial grade
  • 20 gauge is our mid-range thickness
  • 22 gauge is our thinnest, and is sometimes referred to as “budget grade”  

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.

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.

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.
