When we built our home ~40 years ago, we had a well drilled which necessitated a pressure tank and lots of pipes in our basement. And a filter that was supposed to be changed every few months (I didn’t always do that). This involved balancing atop a ladder and getting soaked to the elbows. Been doing this unpleasant chore for four decades.
Couple of weeks ago we had a plumber come out to work on the filter and he sent a sample of our water to a lab. A week later the report came back and they found nothing in our water. No need for a filter.
This might be the result of the new well we had drilled last year but who knows. All I know is I’m done with this messy chore.
