Cast iron drain cleaning

[Jetboy55]

I'm replacing the cast iron dwv in my house. I have 3 stacks (2 baths, 1 kitchen) that go into the concrete and then join together. I want to, at least, have them cleaned really well....a fresh start so to speak to go along with the pvc above grade. I've seen a chain type of cast iron cleaning, and it seems the most thorough. Any idea what it would cost to have my 3 stacks and common drain cleaned this way? Probably 90 feet of pipe total, 30 feet each.

Before you decide to use the chain knockers you better consider the condition and age of the CI

You may want to consider using a 3/4" cable decent cutter and then use a water Jetter as a finishing tool to restore full flow as origionally intended

Thanks. My cast iron is from 1963. I haven't seen any signs of severe degradation, no holes or soft spots above grade. But I know the interior looks nasty with allot of tuberculation and rust.
