Code‑Smart, Safety‑First Guidance
From venting and combustion air to scald protection and expansion tanks—we flag what matters and why. We cross‑check manuals and common code requirements and explain it in plain language.

Sizing Tools, Calculators, and Cost Clarity
Match grain capacity to your hardness and household size. Estimate tankless GPM, salt use, filter life, and long‑term costs—so you buy once and buy right.

Why Trust Water System Wiki
Water System Wiki is an independent resource built by people who actually turn wrenches. We document installations, failures, and fixes across softeners, heaters, filters, and whole‑home plumbing. We buy or borrow equipment, run practical tests when possible, and share what holds up in real houses—not just on spec sheets.
Our editorial process blends experience and rigor: research grounded in manuals, safety standards, and reputable industry sources; hands‑on verification in test rigs or live installs; peer review by seasoned contributors; and clear, plain‑English editing. We cite sources, note limitations, and update guides as products evolve. Have a question or a correction? Contact us—we read every message.
