What TankAuthority Is
TankAuthority is an independent information resource focused on two things: water storage tanks (50 to 20,000 gallons) and RV water systems (fresh, black, and gray water). Every page is written to answer real questions from real buyers — not to fill word count or pad affiliate revenue.
The water tank category is dominated by manufacturer product pages, thin Amazon listings, and generic blog posts that recycle the same five facts. We built TankAuthority to be the resource we wished existed when we were trying to understand the difference between a Norwesco and a Snyder tank, figure out why our black water sensors always read full, or decide whether a 500-gallon or 1,000-gallon trailer setup made more sense.
What We Cover
Our content falls into two pillars:
Water Storage Tanks — Size guides from 50 to 20,000 gallons covering exact dimensions, weight when full, material options, product recommendations, and real use-case guidance. Sub-topics include tank trailers, pressure washing setups, mobile detailing rigs, rental, and installation guides.
RV Water Tanks — Fresh water tank sanitizing and cleaning, black water tank maintenance, gray water guides, portable holding tanks, winterizing and de-winterizing procedures, and product roundups for treatments, sanitizers, and accessories.
We also publish three free calculators: a water weight calculator, a tank volume calculator, and a tank size calculator to help you find the right size for your application.
How We Research
Every product recommendation on TankAuthority is based on a combination of manufacturer spec sheets, verified Amazon product listings and user reviews, cross-referenced specs from Tank Depot and Tractor Supply, and community feedback from RV forums and agricultural groups.
We don't recommend products we haven't researched. We don't take sponsored placements. Affiliate links in our content (disclosed at the top of every relevant page) point to products we would actually recommend to a friend — at the same price you'd find shopping independently.
How We Make Money
TankAuthority earns affiliate commissions from qualifying purchases made through links on this site. We participate in the Amazon Associates program, the Tank Depot affiliate program, and Impact.com's network (which includes Tractor Supply, Home Depot, and Northern Tool).
This means we earn a small commission if you click a link and make a purchase — at no additional cost to you. Affiliate commissions fund the research and writing that goes into every page on this site.
We never accept payment to feature products, change rankings, or write favorable reviews. Full details in our affiliate disclosure.
Content Quality Standards
Every page on TankAuthority is held to the same standard: it must be demonstrably more useful than a manufacturer's product page. That means:
- Size pages include actual dimensions, weight when full, and honest comparisons between brands — not just a list of products to buy
- How-to guides include time estimates, tools lists, and common mistakes — not vague instructions that leave you guessing
- Product roundups include real pros and cons for each pick — not just "this is great, buy it"
- Calculators show the formulas and worked examples — not just a black box result
