I have crane toilets (manufactured in the late 1980s)in the house. The tank mysteriously cracked and flooded the house. I recall reading about this a few years ago that this is a common problem from those years. Does anybody know if Crane has a secret warranty program.
It is more of a problem with older American Standard toilets, but no one has a replacement program. The problem is usually caused by corrosion of the bolts or overtightening the fill valve. Neither of them under the control fo the manufacturer.
We had to replace all Crane toilets in an entire development of townhouses last year. I believe that they were built in 1986. Crane has a program where they will subsidize the replacement of any tank from the specific “defective” year. Best thing would be to contact them.
