      A:  Yes, I picked up a galvanized pipe 4' long, a connector, and another 18" long in 1/2" size when I was at the store. Something like this: https://www.homedepot.com/p/The-Plumber-s-Choice-1-2-in-x-48-in-Galvanized-Steel-Pipe-1248PGL/307815752 , also this: https://www.homedepot.com/p/STZ-1-2-in-x-18-in-Galvanized-Steel-Schedule-40-Cut-Pipe-307-12X18/202310616 and this to join the 2 pipes: https://www.homedepot.com/p/STZ-1-2-in-Galvanized-Iron-Coupling-PDG-CO-12/316911647

        Q:Is description correct?... Descriptions says 3/4 inch pipe needed, however I'm quite sure the item in the store is for 1/2 inch pipe.

                    works great
                    I use to use a company to clean my sewer line and they used this product every time. I bought it and it saved me hundreds of dollars.

                      Blocked sewer. Plunged but old disk broke off in the drain. Ordered new disc online for future use. Called LenThePlumber. Incompetent. Canceled online order and bought one at the store and I was able to remove broken disk and clear the drain. Several days later the disc order I canceled was delivered. Have confirmation of cancellation. Oatey says I have to deal with Home Depot. What do I do with the mailed disc?
