About this site
Where Your Gallons Go is a publication of decisions about water-saving plumbing for US homes: one question per page, a plain verdict, and the gallons and dated sources behind it.
Updated 11 November 2026
The questions are the ones homeowners actually face. Is a 1.6 gallon toilet worth replacing? Does a softener waste water? Will a rain barrel be legal where you live? Each page gives the answer for most homes, then lists the conditions that flip it, what to look for on a label, and which parts of the job belong to a licensed plumber or electrician.
What this site is not
It is not a plumber or a contractor. It takes no calls, books no work and does no installs or repairs. It sells nothing itself. When a page says to call someone, it means your water utility, a licensed plumber, or, for a gas smell or a carbon monoxide alarm, 911 (and for gas, the gas utility) called from outside the house.
WaterSense and ENERGY STAR are programmes run by the US EPA (ENERGY STAR jointly with DOE); this site is not affiliated with or endorsed by EPA.
It is also not a product review site. There are no star ratings, no brand rankings and no tests we did not do. Ratings come from EPA's WaterSense program, ENERGY STAR and the federal and state rules they sit alongside, and every figure is linked to the page it came from, with the date it was checked.
Who runs it
The site is run by the same team that runs four plumbing and water-treatment businesses: Plumbing Supply and More, SoftPro Water Systems, Quality Water Treatment, and Central Plumbing & HVAC. Some pages link to one of those businesses where it lists a part or explains a job that fits the decision, and every such link is labelled with the words "run by the same team as this site". Those links do not change any verdict or number, and the method behind every verdict is set out on how we decide.
There is no editor or author to introduce. The byline on every page is the site name, Where Your Gallons Go, because the pages are built from published sources rather than from anyone's personal experience.
How to use it
Start from the house drawing on the home page, or go straight to a room. Each decision page opens with its verdict, then the numbers, then the cases where the answer changes. If your bill's rate is not the $6.06 per 1,000 gallons EPA's calculator uses, the method page shows how to redo the dollars with your own bill.
