Sump Pump Installation
& Repair — Kamloops
Protect your basement from flooding with professional sump pump installation, replacement, and battery backup systems. Properly sized, reliably installed, and backed by warranty.
Your Basement\'s Last Line of Defense
A sump pump does not prevent water from reaching your foundation — that is what perimeter drains, waterproofing, and proper grading are for. What a sump pump does is remove water that makes it into the sump pit before it can flood your basement. Think of it as the safety net at the end of your drainage system. When everything else has done its job, the sump pump handles what is left.
And here is the thing: a failed sump pump is as bad as no sump pump at all. Worse, actually — because homeowners with sump pumps often store valuables in their basements, assuming they are protected. When the pump fails during a spring storm or power outage, the result is a flooded basement and thousands of dollars in damage.
We install, repair, and replace sump pumps throughout the area. We use quality cast-iron submersible pumps from trusted brands and always recommend battery backup systems. The reason is simple: power outages during storms are common here, and that is exactly when your pump is working hardest. A primary pump without a backup is a single point of failure — and basements are too expensive to protect with a single point of failure.

Sump Pump Types — Which One Is Right for Your Basement?
Not all sump pumps are the same. The type, size, and features you choose directly affect reliability, noise level, maintenance needs, and how well your basement is protected. Here is the complete breakdown of the pump types we install and when each one makes sense.
Submersible Pump
The motor and pump are housed in a sealed, waterproof unit that sits inside the sump pit, fully submerged. Submersible pumps are quieter because the water muffles sound, more powerful for their size, and better at handling small debris. They are the standard for residential basements and what we install in 95% of homes.
Pedestal Pump
The motor sits on a pedestal above the sump pit, with only the intake at the bottom. Pedestal pumps are cheaper upfront and easier to service because the motor is accessible. However, they are louder, less powerful, more prone to overheating, and less effective at handling debris. They are also an eyesore in finished basements.
Backup Systems — Because One Pump Is Never Enough
Battery Backup Pump
A secondary submersible pump connected to a 12V deep-cycle battery. When the primary pump fails or power goes out, the backup activates automatically via a separate float switch. Most systems provide 4–8 hours of continuous pumping or several days of intermittent operation. The battery should be replaced every 3–5 years.
Best for: All homes with finished basements, areas with frequent power outagesWater-Powered Backup Pump
Uses your home\'s municipal water pressure to create suction that pulls water from the sump pit. No battery, no electricity required — it runs as long as municipal water is available. Uses approximately 2 gallons of city water for every 1 gallon removed from the pit. Cannot be used with well water systems.
Best for: Homes on municipal water with reliable pressure, long-term power outage protectionOur standard recommendation is a 1/2 HP cast-iron submersible pump with a battery backup system. This combination handles the water volume typical of local basements during spring melt while providing protection during the power outages that often accompany spring storms. For homes with very high water tables or large basements, we may recommend a 3/4 HP primary pump.

Sizing Your Sump Pump — Why Bigger Is Not Always Better
An undersized pump cannot keep up during heavy water events and will burn out from overwork. An oversized pump short-cycles — turns on and off too frequently — which wears out the motor and float switch prematurely. The right size depends on four factors: water volume, head pressure, pit size, and duty cycle.
Here is how we size every pump we install:
Water Volume (Gallons Per Hour)
We measure how quickly water enters your sump pit during peak conditions — typically during spring melt or after heavy rain. A pump must handle at least 1.5x the peak inflow rate to maintain a safety margin. Most residential basements need 2,000–3,500 GPH. High water table areas may need 4,000+ GPH.
Head Pressure (Vertical Lift)
Head pressure is the vertical distance the pump must lift water from the pit to the discharge point, plus friction loss from the discharge pipe. Every 10 feet of vertical lift reduces pump output by approximately 15–20%. A pump rated for 3,000 GPH at 5 feet of head may only deliver 2,400 GPH at 10 feet. We calculate actual head pressure on every job.
Pit Size & Depth
The sump pit must be deep enough to prevent short-cycling. A pump that activates every 30 seconds will fail within a year. We size pits so the pump runs for at least 60–90 seconds per cycle with 3–5 minutes between cycles. Standard pit depth is 24–30 inches. Deeper pits are better for high water table areas.
Horsepower Rating
For most residential basements: 1/3 HP handles up to 2,500 GPH. 1/2 HP handles 2,500–3,500 GPH. 3/4 HP handles 3,500–4,500 GPH. 1 HP is rarely needed for residential applications and is reserved for commercial or very large basements. We never recommend more HP than necessary — it leads to short-cycling and premature failure.
| HP Rating | Typical GPH | Best For | Basement Size |
|---|---|---|---|
| 1/3 HP | 1,800–2,500 | Small basements, low water table | Under 800 sq ft |
| 1/2 HP | 2,500–3,500 | Most residential basements | 800–1,500 sq ft |
| 3/4 HP | 3,500–4,500 | Large basements, high water table | 1,500–2,500 sq ft |
| 1 HP | 4,500–6,000 | Very large or commercial basements | 2,500+ sq ft |
Big-box store pumps are often rated at zero head pressure — meaning the GPH rating is measured with no vertical lift and no pipe friction. In the real world, your pump is lifting water 8–12 feet and pushing it through 20–40 feet of pipe. The actual output is often 30–40% lower than the advertised rating. We size pumps based on real-world performance curves, not marketing numbers.

New Installation vs. Replacement — What to Expect
Replacing an existing pump in an existing pit is straightforward — usually 1–2 hours. Installing a new sump system where none exists requires more work: concrete cutting, pit excavation, discharge line routing, and electrical connections. Here is what each process involves and what you should expect.
Pump Replacement
We remove the old pump, clean the pit of sediment and debris, inspect the pit walls and bottom for damage, and install the new properly sized pump. We replace the check valve if it is more than 5 years old and inspect the discharge line for clogs, cracks, or freezing issues.
New Installation
We locate the lowest point in your basement, cut the concrete floor with a wet saw, excavate the sump pit to 24–30 inches depth, install a durable plastic or fiberglass basin, and pour new concrete around the basin edge. Then we install the pump, discharge line, check valve, and route the discharge to a compliant termination point.
Discharge Line Routing — The Detail That Matters
The discharge line is often the weakest link in a sump system. A poorly routed discharge can freeze in winter, create ice patches on walkways, flood neighboring properties, or violate municipal bylaws. Here is how we do it right:
We handle all permits, bylaws, and compliance requirements for sump pump installations. Improper discharge routing is one of the most common DIY mistakes — and it can lead bylaw violations, neighbor disputes, and frozen lines that disable your pump when you need it most.

Maintenance & Testing — The $150 Visit That Prevents a $5,000 Flood
Sump pumps are mechanical devices that sit in water, run intermittently, and are exposed to debris, sediment, and temperature extremes. They require regular maintenance to remain reliable. The good news: maintenance is simple, inexpensive, and takes less than an hour. The bad news: most homeowners never do it — until the basement floods.
Annual Maintenance Checklist
Pour 5 gallons of water into the pit and verify the pump activates, runs, and shuts off properly
Clean the sump pit of sediment, gravel, and debris that can clog the intake
Inspect the check valve — it should allow flow in one direction only and seal completely when the pump stops
Check the discharge line for clogs, cracks, or signs of freezing damage
Test the battery backup by disconnecting the primary pump and filling the pit
Inspect the float switch for free movement — it should not be tangled, stuck, or obstructed
Verify the GFCI outlet is functioning and the pump cord is in good condition
Check exterior discharge point for proper drainage and no pooling or ice buildup

DIY vs. Professional Installation — What You Should Know
Replacing an existing pump in an existing pit is within the capability of many handy homeowners. But new installations and discharge routing are more complex than they appear. Here is where DIY makes sense and where it does not:
DIY-Friendly
Call a Professional
The most common DIY mistake is improper discharge routing — discharging too close to the foundation, creating ice hazards, or violating municipal bylaws. The second most common mistake is undersizing the pump based on big-box store marketing numbers rather than real-world head pressure calculations. We handle sizing, compliance, and installation so your system works when you need it.
