Hay guys! I ripped up my old ceramic tile floor and replacing with new ceramic tile.i found plywood sub floor i am going to put down 1/2 cement board and then new tile.existing flange set on top of old tile.Will i need to raise flange up or can i just cement board and tile up to flange and use two wax rings?
Thanks for the help

yes you can use two of the thin wax rings.

The flange should be "at least" even with the tile top. I would advise using an Flange Extender if it is lower than the tile. they are available in different thicknesses.use the holes in the flange to secure it to the floor. Double wax seals are an option, but often one will slide when installing the toilet and block the drain pipe.

We will soon be installing porcelain tile in an existing bathroom and we'll need to add flange extenders. The original lead waste pipe is formed over the existing brass flange; the house was built in 1959 and this plumbing appears to be original. My local DIY plumbing supplier recommended cutting out this existing flange and replacing with new ABS - not a happy solution as I really don't want to disturb either the tongue in groove fir sub floor or the finished ceiling beneath the bathroom.

Should I fashion and shim around this existing lead to make the flange extender sit on top of this mess evenly or can I trim the lead flush with the flange? If I do trim the flange I’ll likely replace the brass flange with a fresh one. Is there a sleeve I can insert to direct the flow as this lead liner will no longer reach up to the bottom of the toilet?

Sorry for the many scenarios. A photo of the current flange with a temporary 3/8” sub floor in place is attached.

Thanks

I would have to agree with you except for the wax ring,i would strongly recommend to use plumbers putty to seal your toilet but that just me.

Plumbers putty is not made to seal between the toilet and the flange. It is only for touching/compressed surfaces. Toilets have a gap between the bowl and the flange.

well,me and my fellow UA union brothers and sisters use plumbers putty to seal the toilet.Now that being said,i have used wax rings a couple of times cause the customer wanted it and supplied it in the past but i wont give any warranty on a pull and reset with wax rings but i will give a 5 year warranty using plumbers putty

Never heard of such a thing..plumbers puddy

Now I'm not trying to start something just wondering how does it not dry out or erode?

Never heard anyone using plumbers' putty for toilet installation; perhaps it works. Oatey site doesn't mention that use in its description of uses for plumbers' putty. It does mention that use for a wax ring. Next toilet I do, I'll use the wax ring.

Plumbers putty will shrink slightly and dry out over time. Movement is slight on a properly installed toilet but none the less there will be movement. Once the putty drys and you get a little movement.... You've got a leak. Wax ring is the way to go. Try to get them without the horn. All it does is make you fell better for paying more and restricts the flow.

p.s. I just noticed the putty guy is a journeyman plumber. Might this be some kind of "initiation" from his fellow Master Plumber UA brothers???
