OATEY 271039 – Frequently Asked Questions
1) Will the Cherne 3-inch Long Test-Ball plug fit a 3-inch PVC waste line?
Yes. The Cherne 271039 is sized for 3 in. (75 mm) nominal pipe and the description calls out PVC compatibility. Deflated it measures 2.31 in. across, so it slides into a 3-inch line with room to spare before you inflate it against the pipe wall.
2) How much head pressure can the Cherne 271039 test plug hold back?
Up to 13 psi (0,9 bar), which is 30 ft. (9,1 M) of head. That is the ceiling for a water column standing on the plug during a DWV test, so if your stack test head exceeds 30 feet above the plug, this is the wrong tool for that location.
3) What pressure do I inflate the Cherne Long Test-Ball plug to, and what fitting does it take?
Inflate to 35 psi (2,4 bar), no higher. The plug uses a tank valve for inflation, so a standard air chuck or hand pump works, and a 3 ft extension hose is included so you can set the valve outside the opening rather than reaching into the pipe.
4) Why choose a long test ball plug instead of a short round one for a waste stack test?
Length is the whole point. The 271039 body is 20.75 in. long deflated, so it bridges across a wye or tee branch and seals on the pipe wall either side of the opening. A short ball has nothing to grip on at a fitting and will blow through or seat crooked. Use the long plug where you are testing a waste stack or sealing off a wye; a short plug is for a clean straight run.
5) What keeps the test plug from getting sucked down into the DWV system?
A ring and chain assembly on the body. You tie it off outside the opening so that if the plug deflates or shifts under head pressure it cannot be drawn into the line and leave you cutting pipe to retrieve it. On a multi-story stack test that is not optional practice, it is the reason the ring is there.
6) Is the Cherne 271039 test ball reusable, and what is it made of?
Natural rubber, black, and it is a reusable inflatable test plug rather than a throwaway. Deflate it, pull it by the chain, and it goes in the next opening. Keep it under the 35 psi inflation figure and off sharp cut pipe ends and it will run a lot of tests.
7) What is the Oatey Cherne 271039 part number and how heavy is it to carry up a stack?
Order it as Oatey/Cherne 271039. Product weight is 2.05, light enough to carry up a ladder with the hose coiled in one hand, and it displaces 0.152 in volume when inflated.
