I'm in the process of renovating our basement.I've just busted the floor up in the area of the future bathroom and the existing main drain.Now the stack that goes up through the house is 4-1/2"
cast iron,this isn't the problem.I thought that the pipe under the floor was the same size,but its not,its actually 8".Now
adapters or fittings this size are not avalible @ HomeDepot
of other such stores.
What do I do now ?
