I have an old fashioned toilet in my apt with a diapragm assembly in a section just before the pipe runs into the wall. I need to replace the diaphragm. I have watch the plumber do it countless times but shuttung off the water in the bathroom doesn't seem to cut off the water to the toilet. Help!
Turning both wtaer vallves under the toilet as far as they will go. There is no water running in bath or sink but it is still dripping from the pipe wher I loosenrd thr bolt on top of the toilet.

Does your flush valve look something like this
Click to enlarge the pic. The shut off is under the cap that says control stop. You may have a smaller cap or none at all. The shut off is a screwdriver stop. Once you have the water off you back the cover off at the hex nut on top (push the flush lever first). Once you get it off pull out the guts. You want to replace the entire assembly except for the piston in the center. It's a Sloan retro-fit kit for a water closet. There is another kit for urinals. Any plumbing supply house will have this part
The problem is really the diaphragm replacement. That is right under the cover right?
The water is now off. Thanks

Yes the diaphragm is part of the retro-fit kit. It's much easier to just drop in a new kit rather than trying to get the old one apart to just replace the diaphragm. Little price differenceThanks for using Just Answer
