Key Takeaways
- Check outdoor spigots for freeze damage before you connect a hose.
- Test the sump pump before spring storms, not during them.
- Flush the water heater and test the relief valve.
- Walk the house for drips, damp spots and slow drains.
Outside the House
- Test outdoor spigots. Turn the interior shut-off back on, open the spigot, and check inside the wall for leaks. A pipe that split over the winter may only leak when the faucet is on.
- Check the sump pump discharge line is clear and draining away from the house.
- Clear gutters and downspouts and make sure water drains away from the foundation.
- Look for soggy spots in the yard, which can mean a leaking service line or sewer lateral.
If you see water inside the wall or basement when you open an outdoor faucet, shut it off and call. A freeze-split pipe will keep leaking every time it's used.
In the Basement
- Test the sump pump. Pour a bucket of water into the pit. It should start, empty and stop. See wet basements and sump pumps in Rockville.
- Check the battery backup if you have one.
- Flush the water heater to clear winter sediment, and test the relief valve.
- Look at exposed pipes for drips, corrosion and green crust at fittings.
- Check floor drains by pouring water in to make sure they drain freely.
Kitchen and Bathrooms
- Look under sinks for drips and water stains
- Check toilets for running water with the dye test
- Clean aerators and showerheads of mineral scale
- Watch for slow drains before they become clogs

When to Call a Plumber
Call if you find a leak inside a wall, a pump that won't run, a water heater that's leaking or more than 10 years old, or drains that are slow throughout the house. A spring plumbing inspection covers everything on this list, and our sump pump service gets the basement ready for storm season.
