Test plug performed as expected.
I used this to seal off a 4 inch ID cast iron toilet pipe while the flange was on order. It performed much better at blocking gasses than than a rag hand towel stuffed into the pipe.

Good product if you don’t need greater depth into the pipe
Nice but needed to be deeper ( greater depth) back of product rusts within a year

bought 2, and 1 crack after few months
i bought 2 from homedepot, and they were great. However, couple months into installation, i have observed it is cracked on one of the plug, and would be great to know how to get a warranty claim on it.

    I used these to create drain plugs in the top of my kayaks. I drilled a 4 inch hole and now I can reach in there and get out all of the debris and dead bugs and rinse them out completely and put the plug back in and they stay watertight.
