Toilet - Cast Iron and PVC Closet Flange Problem? I have a style iron pipe with no flange (to attach the...
I have a style iron pipe with no flange (to attach the toilet) that have an opening flush next to the concrete floor in the bathroom. The inside diameter is roughly 3.75". All of the PVC flanges that you can place on 4" cast iron (that I found at Home Depot) own an outside diameter of 3.75". I cannot get them to walk down the pipe without hammering them inside. I have to remove the rubber gasket to do this. When I do hammer it inside, I cannot gain the flange to sit completely on the floor. What am I doing wrong. Do they make these PVC flanges for pipes that are slightly smaller? Am I going to hold to call a plumber?
Answers: They trade a two piece cast flange beside the rubber gasket. (the kind you tighten the 4 bolts and it pulls the bottom into the top creating a trademark around the existing cast pipe.) Try that first. That stated does it look similar to the flange you have will be in motion on the pipe but you can't get it over the launch of the pipe? If that is the valise take a close look at the pipe coming out of the floor. Check to see if the head they used is still on the pipe, even though the old flange is past its sell-by date sometimes the lead remains and therfore change the circumfrence of the pipe. you may need to warmness it with a torch and verbs off adjectives of the old head then you should know how to slide the new flange over and tighten normaly. Hope to be precise your problem...good luck If not use your first answer and convert to pvc near a rubber furnco......
You shouldn't be doing this. Cast Iron and PVC do not mix; from what I can tell from your give somebody the third degree, you are putting a pvc toilet flange into the cast iron pipe (or trying too, but it doesn't fit). This is not how to do this opening, the primary reason is the stamp; the way you are doing it, your bathroom is going to smell close to sewer. The proper way to form a transition from cast iron to pvc is near a rubber coupling. That means you are going to enjoy to cut the cast iron - consequently you need a plumber. Sorry, but unless you know allot roughly cast iron, afterwards it's just going to cost you more if you don't ring a plumber 1st.
