Just a question I was wondering about as I was replacing a toilet this weekend...how long (on average) do those rubber washers that help connect and seal the toilet tank to the bowl last? The toilet I replaced was almost 30 years old and I know in the 10 years we've lived in the house they've never been replaced and I'd "suspect" the previous owner may never have replaced them either. Anybody have an idea on a life expectancy for these washers?
Thanks in advance, Tony
