Season Fall storm season in much of the US: Sep–Nov. Before every purchase, run the three-number check.

What this desk will not write

A refuse list is a boundary, and a boundary is the cheapest quality control a publisher has. Every refusal below has a reason that survives an afternoon of thought. If a page on this site ever drifts into a refused topic, that page is a bug — send it to us and it comes down.

The refuse list

RefusedReason
Product reviews & picksRanking pipe brands buys traffic and sells trust. We give sizing rules; you pick the product that meets them.
Affiliate linksA desk that earns per click cannot be checked against its sources and believed at the same time.
Foundation & footing adviceTouching a structure without a local engineer is how wet basements become cracked basements. That is someone else's license.
Permit shortcuts"Just do it without a permit" is advice with a bill attached. We point at your code, we never route around it.
"News" about drainageNo daily roundups, no "this week in stormwater." This desk has no newsroom; pretending otherwise is a soft 404 of a site.
Guaranteed outcomesNo page promises "your yard will never flood." Soil and storms do not honor promises. We state what a design can and cannot do.
Content for contentIf a page cannot state its extra inch over the top search results, it is not written. The test lives in the desk.

What we do instead

Numbers with units and traps. Boundary tables. Worked arithmetic you can re-run with your own yard. Sources you can open. And a dated stamp on every page so you know when a figure was last checked. If that sounds like less than a "complete guide," good: complete guides are how the internet buried drainage answers under ads.
