The Complete Handbook of Plumbing Valves

Plumbing valves are everywhere in buildings—controlling water supply, isolating sections for repairs, relieving pressure, and preventing backflow. Yet most professionals and serious hobbyists operate with incomplete knowledge: they follow habit, copy what a supplier recommends, or hope YouTube has the answer. The Complete Handbook of Plumbing Valves fills that gap.

This handbook explains how valves actually work, why different types exist, how to choose the right one for your specific application (not just the cheapest one), how to install and configure them correctly to avoid leaks and pressure loss, how to maintain them so they don't fail in an emergency, and what brands deliver real value at different price points. You'll find concrete examples throughout: a tankless water heater that fails because of the wrong valve type, a commercial building that avoids tens of thousands in floor damage because someone chose the right pressure relief valve, a homeowner who discovers after installation that the valve they selected can't handle the flow rate their renovation requires.

Whether you're a licensed plumber, a contractor managing a building system, a facilities manager responsible for maintenance, a builder specifying materials, or a serious hobbyist who wants to understand the systems you're working with, this handbook is your reference.
