As the snow melts off the Chuckanuts and the famous Bellingham rain settles in for the season, your home’s plumbing faces a new set of challenges. Transitioning from winter to spring is the most common time for "hidden" damage to reveal itself.

To help you avoid a basement flood or a spike in your water bill, the team at WhatcomWaterPros has put together this local spring maintenance guide.

1. Test Your Sump Pump (Before the Storm)

With the heavy rainfall we see in Ferndale and the lowlands of Lynden, your sump pump is your home’s MVP.

• The Test: Pour a five-gallon bucket of water into the pump pit. The pump should turn on quickly, discharge the water, and shut off.

• The Warning: If you hear a humming sound but no water is moving, or if it fails to trigger, call a pro immediately before the next "Pineapple Express" hits.

2. Check for "The Winter Freeze" Damage

Did you leave a hose attached during that February cold snap? Even if you didn't see a leak in the winter, the first time you turn on your outdoor spigot (hose bib) in the spring, a cracked pipe inside your wall could start spraying.

• The Test: Place your thumb over the spigot opening and turn the water on. If you can easily stop the flow with your thumb, the pipe is likely leaking inside the wall.

3. Inspect Your Water Heater for "Working Hard" Signs

Our Whatcom County water is notoriously cold coming into the house during the winter, meaning your water heater has been working overtime for months.

• Look For: Small puddles around the base or "rusting" on the tank. If your unit is over 10 years old, spring is the best time for a preventative flush or replacement before it fails unexpectedly.

4. Clear Those Outdoor Drains and Gutters

Spring in the PNW means blossoms and debris. If your perimeter drains or downspouts are clogged with last year's leaves, water will pool against your foundation, leading to "seepage" in your crawlspace or basement. Ensure all water is being diverted at least 5–10 feet away from your home.

5. Be Mindful of "Spring Cleaning" Clogs

As we all dive into spring cleaning, remember that your kitchen sink and garbage disposal aren't trash cans. Avoid putting fibrous vegetables, fats, or oils down the drain. If your sink is draining slowly, a professional hydro-jetting can clear out winter grease buildup and get you ready for summer.
