1. If it is a floor drain, go to the hardware store again to see how to buy a good floor drain, if you must replace the floor drain, there are two situations, one is to only replace the floor drain core, not to change the shell, so that you don't need to do waterproofing, normal replacement on the line, and there is a complete set of replacement floor drains, so that you need to install the floor drain, but also around the floor drain to do local waterproofing, as long as the new waterproof layer covers the old waterproof layer. 2.
