January Plumbing Maintenance Checklist: Start the Year Without Costly Plumbing Problems

January is the perfect time to check in on your home’s plumbing system. After heavy holiday use and colder winter temperatures, your pipes, drains, and fixtures may be under more stress than you realize. A simple plumbing maintenance checklist at the start of the year can help prevent leaks, backups, and unexpected repair bills.

Use this January plumbing maintenance checklist to keep your home running smoothly all year long.

1. Check for Leaks Indoors and Outdoors

Even small leaks can turn into major water damage if left unchecked.

✔️ Inspect under sinks, around toilets, and behind appliances
✔️ Look for moisture, corrosion, or water stains
✔️ Check outdoor faucets and hose bibs for cracks after cold weather

If you notice any dripping or damp areas, it’s best to address them early.

2. Test Your Water Pressure

Low or inconsistent water pressure can be a sign of mineral buildup, leaks, or pipe issues.

✔️ Turn on faucets and showers one at a time
✔️ Watch for sudden pressure drops or sputtering
✔️ Listen for unusual noises in the pipes

Fixing pressure issues early can extend the life of your plumbing system.

3. Inspect Toilets for Silent Leaks

A running toilet can waste hundreds of gallons of water each month.

✔️ Add a few drops of food coloring to the tank
✔️ Wait 15 minutes without flushing
✔️ If color appears in the bowl, there’s a leak

Replacing worn flappers or valves is a quick and affordable fix.

4. Clean and Check Drains

Holiday cooking and gatherings often leave grease and debris in your drains.

✔️ Run hot water through sinks
✔️ Use drain strainers to prevent clogs
✔️ Avoid chemical drain cleaners that damage pipes

If drains are slow or backing up, professional drain cleaning can help.

5. Inspect Exposed Pipes

Cold temperatures can cause pipes to expand and contract.

✔️ Look for cracks, corrosion, or loose fittings
✔️ Check pipes in basements, garages, and crawl spaces
✔️ Add insulation where needed to prevent freezing

Early detection can help avoid burst pipes during winter.

6. Test Shut-Off Valves

Knowing how to stop water flow in an emergency is crucial.

✔️ Turn main and fixture shut-off valves on and off
✔️ Make sure they move smoothly and don’t leak
✔️ Replace stuck or corroded valves

This simple step can save thousands in water damage.

7. Check Your Water Heater

January is a great time to make sure your water heater is operating efficiently.

✔️ Look for leaks around the tank
✔️ Listen for popping or rumbling sounds
✔️ Check the temperature setting (120°F is ideal)

Routine maintenance helps extend the life of your unit.

8. Schedule a Professional Plumbing Inspection

Some issues aren’t visible to the untrained eye.

A licensed plumber can:
✔️ Spot hidden leaks
✔️ Inspect sewer and drain lines
✔️ Recommend preventative repairs

This proactive step can save you money throughout the year.
