Storms that fill the sump pit often cut the power too. We fit a backup and alarm to suit your pit and water supply, then prove it on battery.
A main sump pump rarely quits on a dry day. It quits when a thaw or downpour is filling the pit and the power drops.
In pumps that quit mid-storm we also find floats wedged against the pit wall, check valves stuck open and motors worn out by constant cycling. A sump pump power outage backup gives the water a second way out.
Main pump trouble belongs to sump pump installation and repair; water coming up a floor drain calls for backwater valve installation instead.
The pit and the water supply decide which fits.
A second pump beside the main one, float set higher so it starts only if the main pump falls behind; a charger keeps its battery full.
Main and battery pumps pre-piped on one discharge with a check valve each, for pits where two loose pumps would crowd each other.
Municipal water pressure drives a venturi that draws water from the pit: no battery to run flat, but it uses house water and needs backflow protection.
Most basements on town water get a battery or combination unit; water-powered suits steady municipal pressure and long outages.
When the power fails, a well pump stops too, leaving no pressure for a water-powered backup. That rules them out on estate lots in King City, the Vandorf and Gormley concessions of rural Stouffville and East Gwillimbury acreage, where we pair a battery backup with a high-water alarm. A standby generator helps only if it feeds the sump outlet, and it cannot unstick a jammed float.
Room for both floats. In a narrow or shallow pit, a second float snags on the other pump or the wall, leaving a pump idle as water rises or running dry until it burns out. A tight pit may need enlarging or a combination unit.
A check valve on each discharge. One pump then cannot push water back through the other, nor can the pipe drain back whenever a pump stops. Where the pump maker calls for one, a relief hole below the valve prevents air lock.
What moves the price: pit enlargement, battery capacity, a combination unit or two pumps, a second discharge line, backflow parts, and any new outlet, which is electrician work we flag first. We price in writing after seeing the pit.
Set before anything is bought:
An untested backup is only a guess.
A backup can run all storm unnoticed, and a draining battery gives no warning. An alarm above the backup's start level sounds when the main pump has lost the race, and most controllers also flag a low battery. A loud alarm suits a lived-in house; an empty one needs a text or app alert, and Wi-Fi alarms go quiet when the router loses power.
Batteries do not fail on a calendar; heat, run time and charging all matter. Sump pump battery replacement follows a test on a yearly visit, ideally before the melt. Our spring flooding and sump pump checklist covers the main pump and discharge line.
A tester loads the battery; a green charger light can glow on one that no longer holds a charge.
Terminals are cleaned and tightened. Flooded batteries get distilled water, sealed ones a check for swelling.
The charger must charge, the self-test pass and the alarm carry upstairs.
With the main pump unplugged, the backup must empty the pit. If it slows, the battery is replaced.
Some York Region ground raises the stakes for a backup sump pump. Keswick and the Georgina shore sit flat over a high water table, where lower lakeshore pits can fill through the whole melt. Near the Holland Marsh in Bradford, low land holds groundwater high. By the river in Holland Landing and Newmarket a wet spring lifts the water table, and on the Oak Ridges slopes of Richmond Hill thaw water runs downhill.
Seasonal lakeshore homes. Seasonal places around Keswick, Sutton and Jackson's Point often sit empty through the melt. They need an alarm that reaches the owner or a neighbour, and the sump circuit left on at closing, since the main breaker stops the pump too.
Expect the pit to fill and empty several times.
We pump the pit down, clear silt and check the main pump's float, check valve and discharge first.
The backup sits on a firm base, float above the main pump's. The battery goes in a vented box on a shelf.
Each pump gets its own check valve before the lines join, with cords tied clear of the floats.
We fill the pit until the main pump empties it, then unplug it and the charger and refill: the backup must run, sound the alarm and push water outside.
