Spring Plumbing Inspection Checklist

Why spring is the best time for a plumbing checkup

Winter puts enormous stress on your plumbing system. Freeze-thaw cycles can crack pipes, shifting soil can disturb underground lines, and months of heavy indoor use often reveal wear on fixtures and drains. A thorough spring inspection catches these issues early — before a slow leak turns into a flooded basement or a failing water heater leaves you without hot water during a busy season.

Indoor plumbing inspection

• Check every faucet for drips and leaks — a faucet dripping once per second wastes over 3,000 gallons per year
• Inspect under all sinks for moisture, corrosion, or staining on supply lines and drain pipes
• Flush every toilet and watch for running, slow fill, or rocking at the base — a faulty wax ring can cause hidden water damage
• Test all shut-off valves by turning them fully closed and open — valves that haven't been exercised in years can seize
• Run every shower and tub to check water pressure and look for slow drains
• Inspect your water heater for rust on the tank, moisture at the base, and unusual noises — sediment buildup reduces efficiency by up to 25%
• Check exposed pipes in the basement and utility areas for condensation, green patina on copper, or white mineral deposits at joints

Outdoor plumbing inspection

• Turn on all outdoor hose bibs and check for leaks at the handle and spout — frost damage may have cracked the valve body
• Inspect sprinkler heads and irrigation lines for winter damage before activating the system
• Check the sump pump by pouring a bucket of water into the pit — the pump should activate and drain the water within seconds
• Walk your yard and look for unusually soft or soggy areas that could indicate a broken underground pipe
• Clear any debris from floor drains in the garage, basement, and laundry room

Drain maintenance

Spring is an ideal time to address slow drains before summer entertaining season. Pour hot water down drains weekly to dissolve minor buildup. Use a drain snake or enzyme-based cleaner for sluggish drains — avoid chemical drain cleaners, which can corrode pipes over time. If multiple drains are slow, you may have a main sewer line issue that requires professional inspection with a camera.

When to schedule a professional inspection

If your home is over 25 years old, has galvanized steel pipes, or experienced any plumbing issues during winter, schedule a professional plumbing inspection. A licensed plumber can perform a pressure test, inspect your water heater's anode rod, and use a camera to check your sewer line — catching a tree root intrusion early can save you $5,000 or more in excavation costs.
