Review on Cherne 270016 1 1 1 1 by Toki Louton

Ehhh. not sure if i should blame myself. This resulted in a leak such that the plumbing system pressure was only held for about 6 minutes before the plumbing air pressure leaked out. Very frustrating when trying to find "real" leaks in a DWV system. I'm trying to remember if I made a mistake with that in any way. I'm not a plumber who uses this every day; I only use it for my own house installation. I also bought a 4" plug and it worked fine. I bought a 3" replacement for this locally and it held air perfectly. Unfortunately I bought it too early, before the installation phase of my project, and when i discovered it was leaking it was too late to return the money ba!
