Sulfur in tap water...

Here is one that isn't to pricey and mounts under sink and runs its own dedicated facet. They also have others and this showed the filter lasting about 750 gallons of use.

Thanks a million DON!!!!
I have been looking up all sorts since I saw your posts and the ones I have found were 500 and up.

You might need to look at your piping too. If you have copper piping you may need help installing.

Copper piping is tough to work with and never like cutting pipe and having to thread it to add in connections and such.

All new pvc piping in the home. Bonus there!
I have the sudden urge to collect the water and test it.
Thinking the rural water may also have calcite (fixtures have blue green stains).
I also think that I will be attending the next water board meeting. I think the town's water person is a flunky.
