Disclosure
This page is the affiliate and editorial disclosure for Well Diagnosis. If you buy through an affiliate link after a program is approved, Well Diagnosis may earn a commission. That commission does not change the price you pay. It also does not change the matching rule: treatment class first, brand second. Iron is still iron. Hardness is still hardness. Coliform still goes to the health department.
SoftPro Water Systems is an approved affiliate program. SoftPro catalog links on this site use SoftPro’s tracked URL. Commission is 10% per order. SoftPro does not publish a cookie duration, so this page does not invent one. SoftPro remains a class example in the iron, sulfur, and softener catalogs — not a ranked #1 pick.
Every other brand link on this site is still the official public URL, labeled application pending. There are no invented ?ref= strings and no made-up coupon codes for those programs.
Approved program
SoftPro Water Systems: approved. Tracked URL: https://www.softprowatersystems.com?sca_ref=12189698.DA0R53WyVseZd. Commission: 10% per order. Cookie duration: not published.
Programs in progress
Tap Score / SimpleLab: application submitted, pending. SpringWell: application in progress. Planned, not yet applied or not yet approved: Amazon, US Water Systems, Aquasana, Awin, and impact.com. Do not read that list as current enrollment. We will not claim an approval we cannot verify.
Independence
Pages match a lab sheet to a treatment class. Manufacturer catalogs are references, not rankings. There is no paid placement on this site. If a paid placement is ever accepted, it will be labeled on the page where it appears. NSF listings and the National Ground Water Association contractor lookup are independent of any affiliate relationship.
This site is not a substitute for a state-certified laboratory or a licensed well contractor. It is not medical, legal, or engineering advice. It does not diagnose illness. It does not claim that a filter cures disease, that iron bacteria are harmless in every house, or that a negative home kit means the well is safe.
