Rated 4.0 out of 5 by 2 reviewers.
Rated 4.0 out of 5.0 by Flood insurance I have used these plugs at work.Whenever theres a chance of rain when its high tide we put these plugs in the floor drains.I bought one for my house just in case of a Sandy type flood. September 13, 2016
Rated 4.0 out of 5.0 by test your plumbing system for leaks This is necessary when having your new drain, waste, or vent lines inspected by a inspector, who will want the plug inflated at the end of the line and filled completely with water to check for leaks. You can also do this to your existing system to satisfy your own interest. Although these come in different sizes this 4" will be for your 4" waste line. What I like is that it is made of seemingly quality rubber and has a decent-sized chain to remove easily. What I don't like is that the air fitting is close to the body making it difficult to fill with and let out air. It would be easier if it had the fitting connected by a long tube that the longer test plug utilize. Because of this and because of the price difference, I would consider this a homeowner, single use, or very occasional use for someone in the trades. Any more than a couple times a year use and I would recommend upgrading to the longer, better-performing one. August 23, 2016
