We would like to replace the pipes running from one of the apartments kitchen drain to the basement or part of the pipes causing the problem. Every year the water backs up in one of the apartments kitchen sink. Snaking the kitchen drain clears it, about 30 feet or so. This building is a two level building and we will like to have this problem resolved. Please call for onsite visit if possible to quote. The building is located at Dufferin and Dundas in Toronto.
