WH2L Hub is a small reference site run by WH2L Digital. It exists because ordinary household questions ("which cartridge is this?") often get scattered or wrong answers online, and getting them wrong costs people money and store trips.
How we write
- Sources first. Part numbers, fit and measurements come from manufacturer pages, manuals, spec sheets or retailer listings we actually fetched. Every page links its sources.
- Disagreements shown. When two sources (sometimes two pages from the same manufacturer) disagree, we say so and explain which we'd trust.
- No invented numbers. If we couldn't source a measurement or a fit, it isn't on the page.
- Our own words and drawings. We don't copy manufacturers' text or images.
- No fake reviews. We don't publish testimonials or star ratings.
What we are not
We're not plumbers, and we're not affiliated with any brand mentioned. These guides cover DIY parts identification. If a valve body is damaged, the valve turns in the wall, or water shows up inside a wall, call a licensed plumber.
Topics
We're starting with faucet and shower cartridges. Other topics will follow as we can source them properly.
