Annual Plumbing Maintenance Checklist for Texas Homeowners

Preventive plumbing maintenance is the most cost-effective investment a Texas homeowner can make. Most plumbing emergencies — burst pipes, sewer backups, water heater failures, and major leaks — develop from small problems that could have been caught and fixed for a fraction of the emergency repair cost.

Water Heater Maintenance

Flush your water heater tank annually to remove sediment. In hard-water Texas areas, every 6 months is better. Test the temperature and pressure relief valve by lifting the lever — water should flow freely and stop when released. Check the anode rod (the sacrificial metal rod inside the tank) every 2-3 years — if it is more than 50% corroded, replace it to prevent tank corrosion. Inspect all connections for moisture, corrosion, or drips.

Drain and Sewer Maintenance

Pour a pot of boiling water down each drain monthly to dissolve grease and soap buildup. Clean drain screens and stopper mechanisms in all sinks and showers. Schedule professional drain cleaning every 18-24 months. If your home has mature trees near the sewer line, schedule a sewer camera inspection every 2-3 years to check for root intrusion before it causes a backup.

Fixture Checks

Inspect every faucet for drips — even small drips waste thousands of gallons annually and indicate worn internal components. Check every toilet for running water — add food coloring to the tank and wait 15 minutes; if color appears in the bowl without flushing, the flapper needs replacement. Inspect supply line connections under every sink and behind every toilet for moisture or corrosion. Test all shut-off valves to verify they close fully.

Pipe Inspection

Visually inspect all accessible pipes for corrosion, green patina on copper, white mineral deposits, or moisture. Check water pressure with a gauge at an outdoor hose bib — normal is 40-60 PSI; above 80 PSI risks pipe and fitting damage and should be addressed with a pressure regulator. Look for signs of concealed leaks: water stains on ceilings, bubbling paint, musty odors, or warm spots on floors.

Seasonal Preparation

Before winter: insulate exposed pipes in attics and garages, disconnect garden hoses, install hose bib covers. Before summer: check outdoor faucets and irrigation connections for leaks, verify the water heater is keeping up with demand, and clean washing machine hoses and connections. Year-round: know where your main shut-off valve is and test it annually.

When to Call a Professional

Schedule a professional plumbing inspection annually if your home is over 15 years old, has galvanized or polybutylene pipes, or has a history of plumbing problems. A licensed plumber checks things a homeowner cannot — sewer camera inspection, water pressure testing at multiple fixtures, water heater internal assessment, and concealed pipe condition evaluation.
