OATEY 42374 – Frequently Asked Questions
1) Will the Oatey 42374 brass cleanout plug thread into a 4 inch cast iron or PVC cleanout fitting?
The 42374 is sized for 4 inch fittings and is female threaded, so it threads into a 4 inch cleanout ferrule or fitting hub with matching male thread. Measure the fitting, not the pipe run, before ordering: nominal 4 inch cleanout openings vary by fitting brand, and this plug is a single 4 inch size only.
2) Does this Oatey cleanout plug meet Southern Plumbing Code requirements for a raised square head?
Yes. The 42374 brass plug has a raised square head and is built to satisfy Southern Plumbing Codes that require that head style. That raised square is also what gives you something to grab when the plug has been in the ground for years.
3) What is the pressure rating on the Oatey 42374 brass cleanout plug?
Maximum working pressure is 10 psi. That is a drainage-service rating, which is what a cleanout sees. Do not put this plug on a pressurized water or gas line.
4) What tool do I need to install or remove the 4 inch brass cleanout plug?
Slip joint pliers on the raised square head. No special wrench or socket needed, and the raised head means you can back it out later without chewing up a recessed slot.
5) Will a brass cleanout plug stop sewer gas from coming up through the cleanout?
That is the job. The 42374 caps the pipe to help keep sewer gas out of the space, which is the usual reason a property manager replaces a cracked or missing plug on a floor or wall cleanout.
6) Should I use a brass cleanout plug or a plastic one?
Brass is the choice where code calls for a raised square head or where the plug gets removed repeatedly for rodding. Plastic plugs can gall or crack in a cast iron ferrule after a few removals. The 42374 is a solid brass body in the 4 inch size.
7) What is the exact part number to reorder this 4 inch brass cleanout plug?
Oatey model 42374, the 4 in. 185 brass cleanout plug. Order by that number to get the raised square head version rather than a countersunk plug.
