M22 Sizing Water Service Lines and Meters, 4th Edition

Home » M22 Sizing Water Service Lines and Meters, 4th Edition

When it comes to the world of water service lines and meters, few names carry as much weight as Peter Mayer. If you’re in the business of making sure water gets from point A to point B—without any drama—you’ve probably crossed paths with the M22 manual. And guess what? Peter Mayer has been at the helm of not just one, but two major updates.

Fast forward to 2024: Peter chaired the subcommittee responsible for the 4th edition of the M22 manual. This isn’t just a light touch-up—it’s the go-to guide for anyone who wants to get water service sizing right the first time. The manual is packed with fundamental guidance, best practices, and the kind of wisdom that only comes from years in the trenches (sometimes literally).

But Peter’s influence didn’t start there. He also led the charge for the 3rd edition update, which hit the shelves back in 2014. That means for over a decade, Peter’s fingerprints have been all over the evolution of how we size up water service lines and meters.

So, next time you open the M22, remember: there’s a good chance the clarity and practicality you find inside are thanks to Peter Mayer’s leadership. Here’s to the unsung heroes who keep our water flowing—and who make sure the manuals are actually worth reading.
