OATEY 273348 – Frequently Asked Questions
1) Will a Cherne Econ-O-Grip plug hold up in a line carrying chemicals or drain cleaner residue?
The sealing element is chemical-resistant nitrile rubber and the hardware is stainless steel, so incidental contact with the chemicals typical of a waste line will not attack it the way plated steel hardware would. It is a mechanical plug for DWV service, not a pressure vessel, so keep it inside the 2 psi back pressure limit.
2) Should I buy a mechanical plug like this or an inflatable test ball for a 4 inch drain?
A mechanical plug such as the 4 in. Econ-O-Grip is the simpler choice when you are sealing a short run or a cleanout and only need to hold low head, up to the 2 psi (about 5 ft. of water) limit on this one. An inflatable test ball is what you move to when you need to seat inside a pipe past the opening, bypass flow, or hold a taller water column for a code test. This plug is explicitly not for pressure tests.
3) Why stainless steel hardware on a test plug instead of plated steel?
Stainless hardware is what lets the plug come back out of the pipe after it has been sitting in a wet line. Plated hardware corrodes and the wing nut or expansion bolt seizes, which is how plugs get cut out instead of reused. The 273348 uses stainless steel hardware and a stainless finish throughout, so an MRO crew can keep it in the truck and reuse it across jobs.
