A wrong figure, an old price, a system we missed or a question about a score: write to us.
To get a useful answer
- For a correction, name the page and link the official page that settles it.
- For a new system, give the brand, the exact model and its official US store page.
- For a question about your own water, send the figures from your test report (hardness, iron, manganese, pH). We cannot interpret a water test for health purposes; your local health department or a certified lab can.
What we cannot do
We do not sell or install water treatment systems and have no access to orders. For delivery, warranty or returns, contact the store or the manufacturer. We never accept payment for a score or a rank (see the disclosure).
