The Ultimate Seasonal Plumbing Maintenance Checklist for Homeowners

A simple quarter-by-quarter checklist to catch small plumbing problems before they become expensive emergencies.

Winter (Dec-Feb)

Insulate exposed pipes in unheated spaces if you're in a freeze-prone area. Check your water heater for sediment buildup and consider a flush. Test your sump pump if you have one, ahead of winter storms. Inspect visible pipes for any early signs of corrosion after the wetter months.

Spring (Mar-May)

Check for slab leaks or hidden winter damage — look for unexplained water bill increases. Inspect exterior hose bibs and irrigation lines for winter freeze damage before heavy spring use. Test your main water shut-off valve to confirm it still turns freely. Schedule a sewer camera inspection if your home has mature trees near the sewer lateral.

Summer (Jun-Aug)

With higher water usage from irrigation and guests, check for running toilets and dripping faucets that waste water during peak-usage months. Clean faucet aerators and showerheads of mineral buildup. If you're a mountain or high-desert household, monitor your water heater and AC condensate lines, which see heavier use in summer.

Fall (Sep-Nov)

Before winter arrives, insulate any exposed pipes, disconnect and drain outdoor hoses, and have your water heater inspected — this is the best time to catch a failing unit before a cold-weather emergency. Check grease trap and kitchen drain maintenance schedules if you run any home-based food service.

Year-Round Habits

Never pour grease down drains. Use drain strainers in showers and kitchen sinks. Avoid chemical drain cleaners, which can damage older pipes — call a plumber for persistent clogs instead. Know the location of your main shut-off valve so every household member can act fast in an emergency.

When to Call a Professional Instead of DIY

Anything involving gas lines, sewer lines, or your main water line should go to a licensed plumber. DIY is generally fine for simple fixture-level issues (clearing a hair clog, replacing a worn washer) but not worth the risk for anything connected to your home's core systems.
