Are any of the online water testing services useful? reliable and accurate. It seems that it costs about $150.00 for a test. http://www.discovertesting.com/products/display_products.sd?iid=27&catid=7&loc=show&headTitle=Drinking%20Water%20Full%20Lab%20Analysis%20Kit Are there any other recommendations? I seem to have a lot of orange sediment in my water. This filter was just changed 2 days ago. I want to have a complete analysis before and corrections are made.
