OATEY 270032 – Frequently Asked Questions
1) What pipe size does the Cherne 270032 Test-Ball plug fit?
The Cherne 270032 is a single-size plug for 3 in. (75 mm) pipe. Deflated it measures 2.64 in. diameter by 5.25 in. long, so it slips into a 3 inch line and expands against the wall once inflated. Single size means it is not a multi-size plug: use it in 3 inch DWV only.
2) What do I inflate the Cherne 270032 to, and with what?
Inflate to 35 psi (2.4 bar), no higher. It uses a standard tire air fitting, so a shop compressor with a tire chuck or even a hand pump does the job. Note the inflation pressure and the back pressure rating are different numbers: 35 psi goes into the ball, 13 psi is the most the line can push against it.
3) What keeps the plug from getting sucked down the stack during a test?
A ring and chain assembly is built into the plug. You tie it off at the opening so the ball cannot be drawn into the DWV system if it slips or deflates. Standard practice on any plug set behind a tee where you cannot reach it.
4) Will this plug seal in old cast iron that is out of round?
The body is natural rubber, which expands enough to seal both round and out-of-round pipe. That matters in older cast iron, clay or distorted PVC where a rigid mechanical plug will not make a face. It works in every pipe material used for drain, waste and vent.
5) What is the Oatey part number for the 3 inch Cherne Test-Ball plug?
Order Oatey/Cherne model 270032, the 3 in. Test-Ball plug, black rubber body with ring and chain. Same number appears on the Cherne packaging.
