Big offset - can't stop blowing out rings...please help

[acc]

The good news is that my wife can set a Kohler Persuade in about 30 minutes. The bad news she is sick of practicing and I keep blowing out wax rings every few months.

I'm pretty sure the source of the problem is a 2" cast iron offset flange set in a concrete floor. We are in a high rise and can't really touch the concrete.

Does anyone have any potential solutions that don't involve changing the offset flange?

Do you plunge the toilet often? Vigorous plunging can blow out wax rings.

I wouldn't think an offset flange by itself would lead to wax ring failure, but let's see what the pros say.

If you will do a search on Kohler Persuades and find the thread started by Nickinfinity, you may find the answer to you question from a number of folks. Briefly, it's a lousy toilet. You will bless the day you install a Toto...any Toto.

The shape of the offset flange may require you to make one by cutting a wax ring and adding some additional length to it to from another to make it around the flange edges...depends on the model. Plus, if it is not on top of the finished floor, you may need to do this with a jumbo (thick) version.

If I was going to replace the toilet, I'd consider one of the Totos that use the unifit adapter, or maybe the Aquia that allows you to install the adapter to the flange, then set the toilet down on the adapter. It would be easier to ensure you got a good seal because you could feel and see what you're doing, rather than trying to balance 100# toilet hovering over the flange trying to get it aligned without dislodging things.

I assume this is an oval cast iron flange with a "ledge" about 1 1/2" below the floor. If so, then your only option is to install a conventional flange and buy a toilet which will fit the new mounting dimension, unless it becomes too far back to fit any conventional toilet.
