OATEY 271020 – Frequently Asked Questions
1) Will the Cherne 271020 Test-Ball plug fit a 2 inch DWV line?
Yes. The Cherne 271020 Long Test-Ball is a 2 in. (50 mm) nominal plug. Deflated it measures 1.5 in. diameter, so it slides into 2 inch pipe before you inflate it, and the long 18.25 in. deflated body is what lets it seat through a wye or across a stack joint.
2) How much head pressure can a 2 inch Cherne Long Test-Ball plug hold during a DWV test?
It holds up to 13 psi (0,9 bar), which is 30 ft. (9,1 M) of water column. For a waste stack test that means roughly three stories of standing water above the plug. Anything taller and you need to break the test into shorter sections.
3) What pressure do I inflate the Cherne 271020 test plug to, and what fitting does the air chuck need?
Inflate to 45 psi (3 bar). The inflation connection is a standard tank valve, so a normal tire-type air chuck or hand pump threads right on. A 3 ft extension hose comes with the plug so you can inflate it from outside the pipe.
4) Should I use a long test ball or a short one for testing a waste stack?
Long is the right choice for stack work. Cherne's Long Test-Ball plugs are built for waste stack testing and the extended 18.25 in. body spans a wye or hub so it seals across the fitting rather than just inside a straight run. Short-bodied balls are for plugging a single straight section or a cleanout.
5) Will a Cherne test ball plug get sucked into the pipe when the test water drains?
That is what the ring and chain assembly on the 271020 is for. It gives you a tie-off point so the plug cannot be drawn down into the DWV system while the line is under test or draining.
6) Can this test plug be used in PVC DWV pipe?
Yes, the 271020 is listed as compatible with PVC pipe. The body is natural rubber, which conforms to the pipe wall for the seal and will not mar plastic.
7) Is the Cherne 271020 one plug or a kit, and what part number do I order?
Order Oatey part number 271020. It is a single 2 in. Long Test-Ball plug with the ring and chain assembly and a 3 ft extension hose included. Shipping weight is 1.4.
