Plumbing in Denver: what locals should know
Water quality
Denver 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
Denver 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.
Material recommendation
PEX piping is the top recommendation for repiping in Denver. It's flexible, resists freezing better than rigid pipes (it expands slightly), and typically costs 30-40% less than copper to install.
Local tip
Many Denver 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.

What pitfalls should I watch for hiring a plumber in Denver's HOA neighborhoods?
Check that any Denver contractor doing plumbing work carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides. In Denver, verify your plumbing work contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work. In fast-growing Denver, some contractors take on more work than they can handle. Ask about their current project count — a reputable plumbing work contractor runs 2-4 jobs simultaneously, not 10-15.
