Plumbing in St. George: what locals should know
Water quality
St. George has very hard water, which accelerates mineral buildup in water heaters and reduces their lifespan by 2-4 years. A whole-house water softener or tankless unit with a descaling system is strongly recommended.
Freeze risk
St. George gets cold enough for frozen pipes to be a regular concern. Insulate pipes in crawlspaces, garages, and exterior walls. When temperatures drop below 20°F, let faucets drip slightly overnight.

In St. George's cold climate, PEX piping offers a key advantage: it can expand slightly when water freezes inside, making it more resistant to burst pipes than rigid copper or CPVC.

If your St. George home was built in the 1990s or later, your supply pipes are likely in good shape. The most common plumbing issues in newer homes here are water heater replacements and fixture upgrades.
