Sump pump: test it before winter and before the spring thaw
Updated
The sump pump is the most forgotten appliance at the cottage: it sits in its pit at the bottom of the basement for months. The day the snow melts all at once, or heavy rain lands on ground that’s still frozen, it has to start on the first try — and nobody’s there to check.
What to do: the test in six steps
Two moments matter: in the fall, before you leave the cottage for winter, and at the end of winter, before the thaw. The test takes a few minutes.
1. Look before you touch
Lift the pit cover if it comes off by hand. Check the water level, any mud, gravel or debris, and where the float sits. Make sure the plug is fully in and the cord isn’t damaged. If water is touching the outlet, don’t touch anything and call an electrician.
2. Slowly pour water into the pit
With a bucket, pour water in gently until the float rises. The pump should start on its own, empty the pit, then shut off as the float drops. If it doesn’t start, hums without pumping, or won’t shut off, write it down: that’s a call to the plumber.
3. Listen to the check valve
When the pump stops, the water left in the discharge pipe should be held back by the check valve. The sound of water rushing back into the pit and a pump that restarts right away can mean the valve isn’t closing.
4. Follow the pipe to its outlet
Outside, find where the water comes out. The outlet should be clear, away from the foundation, with water flowing away from the house. In winter, an outlet buried in snow or plugged with ice can stop the pump from emptying the pit.
5. Check the backup pump, if you have one
If a battery backup pump has been installed, find its indicator light and test button as described in the manufacturer’s manual. Batteries don’t last forever: note the install date if it’s written on it.
6. Take photos and notes
A dated photo of the pit, the float, the outlet and the outside discharge. Season to season, those photos show whether mud is building up or the water is sitting higher than before.
Why it matters so much in the Townships
The thaw comes fast. In Brome-Missisquoi, a mild spell with rain can melt a lot of snow quickly while the ground underneath stays frozen. The water can’t soak in: it runs toward the low point, often the foundation.
Sloped lots. In Sutton, Abercorn and Potton, plenty of cottages are built into the side of a mountain. Water coming down the slope ends up against the uphill basement wall, and the foundation drain sends it to the pit.
Outages hit at the worst time. The storms that bring rain and wind also knock out power. A pump without electricity doesn’t pump, and the pit fills while the cottage sits in the dark.
The pump works rarely, then a lot. It can sit idle all winter, then have to run often in spring. A float jammed with silt or a seized motor only shows up at that moment.
Where the water goes. Sump water shouldn’t be sent into a septic system, which isn’t designed to take it. In towns, many municipalities also regulate connections to the sewer. Ask your plumber and your municipality what applies to your place.
Prevention: what you can do, and what belongs to a plumber
What an owner can do:
- Do the bucket test in the fall and before the thaw.
- Keep the outside outlet clear of snow and ice, and downspouts pointed away from the foundation.
- With the pump unplugged, lift out floating debris by hand — without taking anything apart.
- Keep the pit cover on so nothing falls in.
- Write down the pump model and install date somewhere you’ll find it.
What belongs to an RBQ-licensed contractor:
- Replacing a pump, float or check valve.
- Installing a battery backup pump or a high-water alarm.
- Changing or extending the discharge pipe, or moving where the water is released.
- Installing or checking the pump’s outlet and circuit (master electrician).
In an empty house, how long before anyone notices?
A pump that doesn’t start makes no noise. Water rises in the pit, spills onto the basement floor, and nobody knows until the next visit. In spring, when the thaw lasts several days, the difference between a quick visit after the mild spell and finding it on your next weekend up shows on the walls and in the stored boxes.
A connected water-level alarm helps, but it also depends on power and internet — exactly what fails during a storm. How often someone stops by sets the maximum length of any damage.
What we look at on a visit
Every visit, we check the water level in the pit, make sure the float moves freely and the plug is in, and note whether the pump is running non-stop. We confirm there’s power and look through the panel door to see whether the pump breaker has tripped — never resetting anything without your go-ahead. We run a flashlight over the basement floor and lower walls, log the hygrometer reading, and outside we check that downspouts carry water away from the foundation. With a spring opening, these checks are done before your first weekend up.
If the water is high or the pump doesn’t respond, we call you the same day with photos, and meet an RBQ-licensed plumber on site if needed.
