Review on Cherne 269840 Plug 2 Inch Kwik by Lance Levatte

Used this expansion plug in two different 1/2" galvanized pipes on the water side. I used a wire brush on the battery compartment inside to descale/scale high quality city water. I highly doubt the inside walls were "sharpened" at all with that soft wire brush. It's a shame. Hold the plug at a certain depth, maybe add larger diameter flat washers to either end of the rubber like I did, then use this tube to seal the deal repair tape and sticky hard when cured gray sticky that comes with a 4ft tape kit I forgot the brand but will check soon I have one Got 4 foot kit because of two pipe plugs.It doesn't drip and is rock hard under full load.Apparently a retired computer program called in to correct the plumbers' incompetence.
