Arizona Summer Plumbing Tips — Protect Your Pipes

Published September 2026 · Pro Plumber Laveen AZ

Arizona summers push your plumbing to the limit. Temperatures regularly exceed 110°F in Laveen, putting stress on water heaters, pipes, and fixtures. Here's how to protect your plumbing during the hottest months.

Water Heater Care

• Lower the thermostat: With incoming water temperatures much warmer in summer, your water heater doesn't need to work as hard. Lowering the setting to 120°F reduces strain and energy use.
• Flush the tank: Summer is a great time for annual maintenance. Flushing removes sediment that's built up from Laveen's hard water, improving efficiency and extending the unit's life.
• Insulate if in the garage: If your water heater sits in an unconditioned garage, the extreme ambient heat adds stress. A water heater blanket can help regulate temperature.

Pipe Protection

• Insulate exposed pipes: Pipes running through attics, exterior walls, or unshaded areas can reach extreme temperatures. While Arizona doesn't freeze often, thermal expansion from heat can stress joints and connections.
• Check outdoor hose bibs: Inspect outdoor faucets for drips or leaks. The rubber washers in hose connections deteriorate faster in direct Arizona sun.
• Watch for slab movement: Laveen's clay soil contracts significantly during dry summer months. This movement can stress underground pipes and sewer lines.

Drain Maintenance

• Run water in unused drains: In summer, P-traps can dry out faster — especially in guest bathrooms or utility sinks — allowing sewer gas into your home. Run water briefly in every drain weekly.
• Watch what goes down the garbage disposal: Summer means more cooking and entertaining. Avoid putting grease, fibrous foods (celery, corn husks), or starchy foods (pasta, rice) down the drain.

Monsoon Preparedness

Laveen's monsoon season (June–September) brings sudden, intense storms that can overwhelm drainage systems:

• Clear yard drains: Remove debris from outdoor drains and gutters before monsoon season.
• Check sewer cleanout caps: Ensure your sewer cleanout caps are in place to prevent storm water from entering the sewer line.
• Know your shutoff: In case of flooding, know where your main water shutoff valve is and make sure it's accessible.
• Grade your yard: Ensure water drains away from your foundation, not toward it.
