I need to cut in a floor drain in my unfinished basement. I want it to look clean once the concrete is patched. What is the best way to cut the concrete to have a clean edge? A friend of mine is a excavator and has a Stihl saw used to cut concrete pipe, but it makes lots of dust and the gas smell in the house would be horrendous! Any ideas?
Also, the floor drain (PVC) I bought has a 2" outlet. The existing main sewer is cast iron (either 4" or 6"). I was planning on using an 4or6"x2" wye, with a short piece of 4or6" pipe out of each end and a Fernco style fitting on each end. Does this seem right? How do I cut the existing cast iron pipe?
