I put in a new tile floor and my toilet flange is too high. The top of the flange is about 3/4" above the floor and I'm looking for the right way to correct.

I had one plumber who said they would cut the cast iron at the stack and run PVC over and up to the toilet, and attach a plastic flange.

I do have a Sawzall, so I could cut the cast iron. Is that a good idea?

Any suggestions?

Thanks,

Dan
 
Options in order of increasing 'properness':

1) put the toilet on a platform
2) raise the whole floor
3) lower the flange (not sure why he's counselling to replace anything more than the flange down to the closet/90 bend...)
 
I doubt you get very far with sawzall. Probably following the plumber's advice is the best way to go. Messing with the cast iron is labor intensive and you're probably going to break it trying to knock off the 3/4"...PITA...
 
I'm not a pro plumber, but I agree with your plumber and Randy.
I've had to raise my two bathroom toilet flanges due to installing tile, and fortunately, I had black plastic ABS drain pipe to work with.
The flange should sit flush on top of and be bolted to the finished floor level with only the thickness of the flange above finished floor level.
Good Luck!

Use snap cutter...Cut it off 2-6" from the tee and replace that sucka with no-hub and PVC. Cheaper, easier, and alot more fun!
 
unless your handy with tools let the plumber do it. If you can cut the cast iron and know how to work with PVC then you can do it. You must cut the cast iron square and about 6-8" from the stack / hub. Attach a banded coupling to the cast iron and run to the floor with your PVC. It is not difficult. You can always try and if you can't do it then call the plumber back. Just know some plumbers don't like finishing jobs people start and may still charge the same price.
 
Closet flange too high

Pound the flange down, taking care not to break it. Reattach it to the subfloor with brass or stainless screws. Recaulk the lead joint. Take a mini grinder and grind down the 1/2" excess pipe. Caution, have a shop vac handy so you can pause occasionally and suck up the metal shavings, otherwise you'll have a hell of a mess. And wear goggles. If any of these steps are beyond you, call a plumber to do all of them.
 
The plumber who replaced part of my cast iron stack with a PVC sani T used a big ratchet type chain cutter. It took him all of 30-40 minutes, or less to do the whole job. Stack cut,PVC sani T installed job done. It paid to have a plumber do this in this case. The stack was cut in the right places. If the stack is not cut square or in the right places problems can and may surface down the road..
