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.
