OATEY 271535 – Frequently Asked Questions
1) Can the Cherne 3 inch Econ-O-Grip plug be used for a pressure test on a DWV line?
No. The Econ-O-Grip plug is not recommended for pressure tests. It holds a maximum back pressure of 2 psi (0.14 bar), equal to about 5 feet of water head, so it is suited to low-head water testing, blocking off a line, and keeping dust and debris out of open pipe. For a full head pressure test on a stack, use a test plug rated for the head you intend to run.
2) What pipe size does the Oatey 271535 Cherne Econ-O-Grip plug fit?
It is a 3 inch nominal plug (75 mm), so it drops into 3 inch pipe or a 3 inch cleanout opening. Sizing is nominal to the pipe, not to an outside diameter, so a 3 inch DWV line is the target.
3) Will a 3 inch Econ-O-Grip plug hold back standing water in a drain line during a low-head water test?
Up to about 5 feet of water, yes. The rated back pressure is 2 psi (0.14 bar), which corresponds to roughly a 5 foot column. Anything deeper than that, including a full-story stack fill, is past what this plug is built to hold and needs a higher rated test plug.
4) Is the Econ-O-Grip test plug reusable, or is it a throwaway dust cover?
It is a mechanical metal plug with a natural rubber O-ring that seals when tightened, so it comes back out and goes back in. Oatey lists it as an effective pipe dust cover as well, which is the job most crews use it for between rough-in and finish. The rubber O-ring is the wear part to inspect before reuse.
5) What is the Oatey Cherne Econ-O-Grip plug made of, and will it hold up in a dirty rough-in?
Body and hardware are metal, with a natural rubber O-ring doing the sealing. The metal body takes wrench tightening and job site handling better than an all-rubber plug, which is why it is common for capping 3 inch stubs through drywall and concrete work.
