you can't cut the pipe back use a cuppler and come off of that
There is a tool that will cut the old flange off that will not damage the pipe. It is brand new to the market and is available through Locke Plumbing supply, or call the manufacturer, Woods plumbing in OKC....405-722-2925
PVC I assume. If you can get to the pipe, cut it and replace a short section along with the flange. There is a flat steel repair ring that could be screwed down on top of the flange. There are flat repair plates for cast iron flanges that might work. They are about 6 inches long, curved the same radius as the flange and slide under the old flange to give you some place for the anchor bolts to slide into.
depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .
flange off tool.....Locke Supply carries them
With a deep floor flange Or a wax seal with a horn and extra long Brass floor flange bolts
No, it is not recommended to glue the toilet closet flange to the pipe. The flange should be secured to the floor using bolts or screws, and the toilet is then secured to the flange using wax rings or sealing gaskets. Gluing the flange to the pipe can make it difficult to remove or replace the toilet in the future.
No, U cnnot accomodate it without pipe sppol, because of isolation.
2 ways: 1. remove the flange and install as replacement frame 2. attach flange normally and fabricate trim to fill gap form removed material
You have to take the lead and packing out that is holding the flange in the next piece of pipe. If your flange is broke where the toilet bolts go, this is very common. There is a repair available for this. It consists of two curved pieces of metal that are about 1/3 of the circumference of the flange. They go under the flange and give you a new place to put the bolt. They are a lot easier to use than replacing the whole flange.
Replace it
Unbolt from the block & take the nuts off studs to exhaust flange. You will need a new gasket for the block & a new one for the flange.
Depends on the type what means I use to replace it CAST Iron/ BRASS / Antimony / PVC / SCREWED TYPE
flange valves are useful because lets say in your sink the faucet is leaking you can use the flange valve to stop the water and repair the sink without having to turn the water for your whole house off.
I would take out the lead bend and replace it with pvc.
