    Can I go from using existing Closet Flg. 4
    My cement floor in the bathroom has settled over many decades (Cabin) and am pretty sure it's done settleing. I leveled the floor up and now have a 4" gap between existing closet flange (4" ID Sch.40) and new finished floor height. My question is can I keep existing Closet Flg. And add on an extension PC.to bring it up to new floor level plus new closet Flg. The drop in extension pieces have been to short at H.Depot/Lowes, they'll cover the 4" gap but I need it to recess farther down into existing C.Flg. I'm trying to avoid cutting and piecing out existing Flg. although seems like the rout to go and then add in a 4" x 7" glued nipple into sewer inlet PC. Topped off w/ new C. Flg. So if there is better/different way I'm all ears. Thank you in advance for the advice.

    Hi Britchie...

    Just as you suspected, forget the extension pieces... 4" is simply too much to make up here.

    What material is the pipe/flange made from? Let me know...

    Thanks for responding... Sounds like your recommending cut out existing C. Flg. And build up from there. The Flange material is PVC and the sewer inlet PC. Is PVC Sch. 40

    If it is PVC then it should be easy enough to cut the pipe and extend it using a coupling and a new closet flange. You may need to purchase an inside cutter (see image) or you could probably make one up if you wanted. If you use an inside cutter to cut the pipe be sure to push a towel down into the pipe just below where you will cut... just in case the cutting tool loosens from your drill and drops into the pipe... can be a lifesaver here... ;)

    Let me know what you think here.

    I saw a cutter @ Suburban Plumbing Supply today and thought about that rout also. I'm 99.9% sure the 4" Closet Flg. is recessed into sewer inlet/Female. So if the cutting rout works I should be able to install that
    4"x7" nipple, glued with thick glue. I guess my next ? Is would you use an outside or inside Closet Flg. Atop of nipple? Thanks also for submitting the picture.

    Presumable your old flange fits inside the 4" pipe. Problem with cutting it out is that you will have to chisel out the concrete around the pipe to put on a coupling.

    Consider this, flanges fit inside a 4" pipe and outside a 3" pipe. Logic says, if you reamed out the stop inside the old flange you should be able glue in a piece of 3" pipe inside the flange for your extension.

    Thank you for your response to my situation. I like to pride myself in doing it yourself, but I also know my limitations. I think I'll have a Master plumber take a look at. Thanks Again
