can anyone recommend a source and any observations on what kind of whole
house filter
systems work and have parts available?

easy maintenance is also a concern.

primary reason for this is high iron content in local municipal water
supply which
causes discoloration (sinks, shower, toilet, etc.)

Most vendors of water filters offer free testing on site by
the salesman. They are not cheap but the more widely
advertised brands suggest they offer some sort of
performance guarantee. Testing beforehand is
prerequisite because no theory forecasts how a particular
filter will work in your house.
