OATEY 270776 – Frequently Asked Questions
1) How much head of water will the 5 inch Test-Kap hold during a DWV test?
Rated to 13 psi (0.9 bar), which Cherne states as 30 feet (9 m) of water column back pressure. That covers a two to three story stack test on a 5 inch line. If your test head exceeds 30 feet, step down the test into sections rather than pushing the plug past its rating.
2) Is the Cherne Test-Kap metal or plastic, and does that matter for DWV testing?
It is a plastic test cap, not a metal mechanical plug. That keeps it light (0.8 lb for the 5 inch) and corrosion free in wet DWV work, and it means no metal bands or nuts to rust into the hub. It is a pressure-test closure, not a permanent cap.
3) Should I use a Test-Kap or a mechanical test plug for my 5 inch waste line?
A Test-Kap goes over the pipe end as a sacrificial test closure for rough-in air or water tests, then gets cut or knocked off when you make up the final fitting. A mechanical plug with a nut and compression gasket goes inside the pipe and is meant to be set and removed repeatedly, which is what you want for cleanout testing or a plug you plan to reuse. For a one-time 5 inch rough-in test, the 270776 Test-Kap is the simpler part.
4) Can I use the 5 inch Test-Kap as a permanent cap on a stub-out?
No. It is a test plug, intended to hold a DWV test up to 13 psi and then come off. For a permanent closure, use a solvent-weld or no-hub cap rated for the system rather than a test cap.
5) What is the Oatey part number and UPC for the 5 inch Cherne Test-Kap?
Order it as Oatey 270776, the Cherne 5 inch Test-Kap. The UPC on the package is 675115270770, which is useful if your supply house stocks several Cherne test caps side by side and the sizes look alike on the shelf.
