The DMV Homeowner’s Guide to Spring Plumbing: 7 Things to Check After Winter

Spring Is Prime Time for Plumbing Problems

Winter in the DMV region takes a toll on your home’s plumbing. Freezing temperatures, ground shifts, and months of heavy indoor use can create hidden problems that don’t show up until spring. The good news? A simple 7-point plumbing inspection can catch these issues before they become expensive emergencies.

Here’s exactly what every Maryland, Virginia, and DC homeowner should check as the weather warms up.

1. Inspect All Outdoor Faucets and Hose Bibs

Your outdoor faucets are the most vulnerable plumbing fixtures in your home. Even a single hard freeze can crack the pipe behind the faucet without any visible damage outside.

How to test: Turn on each outdoor faucet and watch for leaks around the handle and where the pipe enters the wall. Then go inside and check the wall behind the faucet for dampness, water stains, or musty odors. If water sprays from anywhere other than the spout, you likely have a cracked pipe that needs repair.

2. Check Your Sump Pump Before Spring Rains

Your sump pump sat idle (or worked overtime) all winter. Now, with spring rains approaching, it needs to be ready. A failed sump pump is the number one cause of basement flooding in the DMV.

How to test: Pour a bucket of water slowly into the sump pit. The pump should activate automatically, discharge the water, and shut off on its own. If it doesn’t start, runs continuously, or makes grinding noises, it needs servicing or replacement before the first heavy rain.

3. Look for Signs of Frozen Pipe Damage

Pipes that froze during winter may have developed hairline cracks or loose joints that only leak under pressure. These slow leaks can cause thousands of dollars in water damage before you notice them.

Where to check:

• Under every sink (kitchen, bathrooms, utility sinks)
• Around your water heater connections
• In the basement or crawl space along exposed pipes
• Near exterior walls where pipes run
• At pipe joints, valves, and connection points

Look for any green or white mineral deposits on copper pipes (indicating slow drips), dampness, or water stains on nearby surfaces.

4. Test Your Water Heater

Your water heater worked harder than any other appliance this winter. Now is the time to check that it’s still operating efficiently and safely.

Key checks:

• Temperature setting — Should be at 120°F (not higher) for safety and efficiency
• Pressure relief valve — Lift the lever briefly; water should flow freely and stop when released
• Tank bottom sediment — Drain 1-2 gallons from the bottom drain valve. If it’s rusty or full of sediment, the tank needs flushing
• Anode rod — If your water heater is more than 3 years old and hasn’t had the anode rod checked, it may be corroded, leaving your tank vulnerable to rust

5. Clear and Test All Drains

Winter brings heavy kitchen use (holiday cooking, extra guests) and can slow your drains. Before spring, test every drain in your home.

How to test: Run water in every sink, tub, and shower for 30 seconds. Water should drain quickly without pooling. Slow drains usually indicate buildup in the pipes that will only get worse. A professional drain cleaning now prevents a complete blockage later.

Don’t forget: Run water in seldom-used drains (basement sinks, guest bathrooms) to refill the P-trap. A dry P-trap lets sewer gas into your home, causing unpleasant odors.

6. Inspect Your Main Water Shut-Off Valve

In a plumbing emergency, the main shut-off valve is your first line of defense. But if you haven’t used it in years, it may be seized, corroded, or unable to fully close.

How to test: Locate your main shut-off valve (usually in the basement near where the water line enters your home or near the water meter). Turn it off and verify that water stops flowing from a nearby faucet. Then turn it back on. If the valve is stiff, leaks when turned, or doesn’t fully stop the water, it needs to be replaced — ideally before you have an emergency.

7. Walk Your Property for Sewer Line Warning Signs

Tree roots are most active in spring as they seek water — and your sewer line is a prime target. Walk your yard and look for these warning signs of sewer line problems:

• Unexplained soggy or lush patches in the yard (especially in a line from your house to the street)
• Sinkholes or depressions in the ground along the sewer line path
• Foul odors in the yard or near basement drains
• Multiple slow drains throughout the house at the same time
• Gurgling sounds from toilets or drains when other fixtures are in use

If you notice any of these signs, a professional sewer camera inspection can pinpoint the problem before it causes a backup into your home.

When to Call a Professional

While these 7 checks are things every homeowner can do, some problems require professional expertise:

• Any active leak, no matter how small
• Water heater issues beyond basic settings
• Sump pump that won’t activate or runs continuously
• Multiple slow drains (indicating a main line issue)
• Low water pressure throughout the house
• Any sign of sewer line problems
