Review on Oatey 33403 4-Inch Plastic Plug with Galvanized Screw and Wing Nut by Jose Mcdaniel

Very well made and works great! I have a 4 inch cast iron trap that is over 90 years old. I used lead drain plugs on the trap, which can only be installed with a hammer. I always worry about old cast iron cracking when removing or installing plugs. After searching the internet for some time I came across these plastic plugs and decided to try them. You are fantastic! They are easy to assemble and disassemble by hand, which means there is no stress on the cast iron. They also seal the pipe much better than lead plugs due to the rubber gasket. These forks have been a lifesaver for me and have proven to be excellent value for money. You will not be disappointed with this product.
