OATEY 270016 – Frequently Asked Questions

1) What pipe sizes does the Cherne 270016 Test-Ball plug fit?
The Cherne 270016 Test-Ball is a single-size plug for 1-1/4 in. to 1-1/2 in. pipe (35 to 40 mm nominal). Deflated it measures 1.1 in. diameter by 5.5 in. long, so it passes through test tees, sanitary tees and floor drains before you inflate it. Outside that 1-1/4 to 1-1/2 in. range you need a different size plug.
2) How much head pressure can the Cherne 270016 test plug hold back?
13 psi of back pressure, or 30 ft of water head. That covers a typical three-story DWV water test stack. If your column of water is taller than 30 ft, step down to a lower test point or use a plug rated above 13 psi.
3) What pressure do I inflate the Cherne 270016 Test-Ball to, and what do I inflate it with?
Inflate to 40 psi (2.8 bar). It uses a standard tire air fitting, so a shop compressor, a hand pump or a bicycle pump with a Schrader chuck all work. Do not confuse the 40 psi inflation figure with the 13 psi back pressure the plug will hold in the line.
4) Will an inflatable test ball seal in old cast iron that is out of round?
Yes. The 270016 has a natural rubber body that expands to seal in both round and out-of-round pipe, which is why inflatable plugs get used in old cast iron and clay where a mechanical plug will not grab. It is rated for DWV lines in every pipe type within the 1-1/4 to 1-1/2 in. size range.
5) How do I keep a test plug from getting sucked down the drain line?
The 270016 ships with a ring and chain assembly built onto the plug. You tie it off at the opening so the plug cannot be drawn into the DWV system when the test releases. That matters most on small 1-1/4 to 1-1/2 in. branch lines where a loose plug is hard to retrieve.
6) Can I use the Cherne 270016 on a pressurized water or gas line?
No. This is a DWV test plug only, for drain, waste and vent systems, rated to 13 psi back pressure. Pressurized supply and gas piping run well above that and need equipment rated for the service.
7) What is the Oatey part number and weight for the 1-1/4 to 1-1/2 inch Cherne Test-Ball?
Order it as Oatey/Cherne model 270016. It weighs 0.2 lb and the body is black natural rubber, so it is light enough to keep several sizes in a test kit bag.
