Plumbing in Boulder: what locals should know
Water quality
Boulder has moderately hard water which can reduce water heater lifespan over time. Consider a water softener or tankless unit with a descaling system to protect your investment.
Freeze risk
Frozen pipes happen in Boulder most winters. The most vulnerable spots are pipes in exterior walls, unheated basements, and garages. Pipe insulation is cheap ($0.50-1/ft) and prevents expensive burst-pipe repairs.
Material recommendation

Local tip
Many Boulder homes built in the 1970s-80s have polybutylene (gray plastic) water pipes, which are prone to unexpected failures. If your home has them, most plumbers recommend proactive repiping before a catastrophic leak.
