Water Quality & Pressure

Guides on the water itself and the pressure behind it: hard water and softeners, whole-house and under-sink filtration, reverse osmosis, distillers, chlorine and sulfur smells, cloudy or discolored water, weak showers, and pressure that swings overnight. Water heaters live here too, tank, tankless and heat pump, along with anode rods, dip tubes, expansion tanks, thermostats and elements, and the leaks that start at the top or the bottom of a tank. You will find diagnosis articles that walk a symptom back to its cause, and buying guides that name specific products.

Picks are chosen from manufacturer specifications, installation instructions, warranty terms and plumbing code, with attention to fit and to whether replacement parts stay available. That judgment is read alongside manufacturer specifications and the standards a product is built to. Nobody pays to be included and there are no sponsored placements. Some links on these pages are affiliate links, mostly to Amazon; if you buy through one the site may earn a commission at no extra cost to you.
