Hard Water and What It Does to Kitchen Fixtures

By the time the old faucet is out from under the sink, the mineral crust on the supply stops tells the whole story about the water. It is white and hard, and it has been building for years. Water across the Phoenix metropolitan area is hard, and a kitchen remodel in Scottsdale, AZ has to plan around it, as the notes at kitchen remodel scottsdale az primal health with jean describe. Much of the supply comes from the Salt River system and the Colorado River, and both carry a lot of dissolved calcium and magnesium.

What scale actually does

Evaporation in the Sonoran Desert is quick, so droplets dry before anyone wipes them, and hard water leaves calcium carbonate behind. On a faucet spout it clogs the aerator and cuts the flow. Inside a dishwasher it coats the heating element and the spray arms. On a glass cooktop splash or a stainless sink it leaves a haze that wipes off at first and etches in after a few months. None of this is a defect in the fixture. It is the water.

Finishes that hide it and finishes that show it

Polished chrome and dark matte black show every spot. Brushed nickel and a brushed stainless sink hide the haze far better, and a textured finish disguises it further. A pull down sprayer with silicone nozzles can be rubbed clean with a thumb, which keeps the spray pattern open without any tools.

Plumbing choices made during the remodel

The rough-in stage is when this gets handled cheaply, and plumbing work in Maricopa County is permitted and inspected at that stage anyway. A shutoff valve on every supply line lets a fixture be pulled for descaling without draining the house. Copper and PEX both tolerate hard water, but old galvanized stubs in a house from the 1970s are often half closed with scale and are replaced while the wall is open. The water heater is part of the same system, since scale builds on its element and shortens its life.

Filtration and softening

A softener removes the minerals at the point where water enters the house, and a drain for its regeneration cycle has to be roughed in. A carbon filter under the sink improves taste but does little about scale. Some homeowners put a small filter only on the refrigerator and ice maker line. Where the softener goes, and where its discharge drains, is decided before the cabinets are ordered, because the answer sometimes changes the sink base layout.

Keeping it up

A vinegar soak on aerators every few months and a monthly dishwasher descaling cycle keep most kitchens in good order. The work is small. Skipping it for a few years is what turns a minor haze into a replacement.
