We are doing a remodel and will replace two older Toto toilets. They are back to back connected with a "T". I was going to install newer Toto toilets but due to our "T" connection Toto won't support it. I researched American Standard and Kohler and their support reps have said the same thing - they won't perform in a back to back with a "T". Our plumber has told us that to change out the T would be a substantial amount of work (and cost).
I've seen some postings in this forum that indicate that while it's not ideal, it can be done with some possible issues.
Realistically, what type of issues could we expect?
Second, which brand/model would best the least problematic in this config? We do need ADA height, and would like to stick with a major brand where replacement parts won't be a problem down the road. We'd like to keep the price reasonable, but do want decent quality.
One suggestion was a Kohler model with their Ingenium flushing system but from what I can read that's not an especially good toilet - hate to install something I know in advance won't work well.
Thanks in advance for any help.
