X3 on water quality. We use rain water here. The flush mechanisms are good after 50 years. There is no chlorine or any other chemicals added to the water.
I know of people in towns with chlorine in the water that have flush mechanisms fail every couple of years.
The new houses are plumbed with plastic pipes instead of copper. The brass taps fail after a couple of years.
