Hello All
I hope someone can give us some helpful advice on a situation we have.
Our upstairs bathroom didn't have any fixtures when we bought the house 3 yrs ago. After putting in a toilet, tub and vanity in it, we found out the cast iron stack is badly cracked. The crack goes all the way from the floor of the downstairs bathroom to the hub which connects the the piping for the upstairs bathroom. So this will have to be changed.
The piping of the two bathrooms is:
Downstairs toilet has 4" cast iron pipe going straight down to basement and into the ground.
Upstairs toilet has 4" cast iron pipe going straight down to basement and straight out the roof. This pipe is connected in the basement with an elbow and 5 ' pipe to the pipe going into the ground.
WHERE I NEED HELP
If I were to cut out that 7' - 10' cracked cast iron pipe and replace it with solid wall dwv pvc, would the pvc be able to support the 10' cast iron pipe which will sit on top of going out the roof. The other alternate would be to put pvc all the way way up before it shoots out the roof.
Supporting the pipe, I got those 4" riser clamps from Home Depot, but they are a little too big for the pipe, can I cut open that Fernco coupling and wrap it around the pipe and then riser clamp. In addition I will also nail a 2 x 4 under the toilet elbow for extra support.
Thanks
