How We Fund Free Tools
Without Compromising Research
Building and maintaining diagnostic calculators, compatibility matrices, and 100-hour technical guides costs real money. Here's exactly how we fund it — and the principles that ensure it never compromises our research.
The Straight Answer
To keep our technical tools and diagnostic guides free for everyone, we partner with affiliate programs like Amazon Associates. When you click a product link on this site and make a purchase, we earn a small commission — typically 1–4% of the sale price.

Rankings Are Never For Sale
A product's affiliate commission rate has zero influence on its ranking, recommendation, or placement in our guides. If a $500 valve is technically inferior to a $100 sensor for a specific use case, our data will show it — and we will say so explicitly.
Every Affiliate Link Is Disclosed
All links to Amazon and other retailers on this site are affiliate links unless explicitly stated otherwise. We do not use hidden redirects or disguised tracking links. What you see is what it is.
We Decline Paid Placements
We do not accept payment from manufacturers for product placement, "sponsored" reviews, or featured positions in our guides. Manufacturers can submit products for research consideration — but cannot purchase a recommendation.
Your Cost Is Never Affected
Clicking our affiliate links never increases the price you pay. The commission comes from the retailer's margin, not from a surcharge on your purchase. You pay the same price whether you use our link or navigate directly.
FTC Compliance Statement
This disclosure is provided in compliance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 CFR Part 255). LeakCheckPro.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
