Understanding Backup Sump Pumps

A backup sump pump is essential to protect your basement or crawl space from flooding during power outages or primary pump failures. Knowing the different types available, how they operate, and the benefits of adding one will help you make an informed choice for your home’s water management system.

Types of Backup Sump Pumps

Backup sump pumps come mainly in two types: battery-powered and water-powered.

Battery-powered pumps run on a rechargeable battery and kick in automatically when the primary pump fails or during a power outage. They often sit beside the main pump in the sump pit or mount on the wall. The batteries usually require regular maintenance or replacement to ensure reliability.

Water-powered backup pumps operate using your home's municipal water pressure to create suction, removing water without electricity. They are ideal if you want an emergency system that doesn’t rely on power but may cause increased water use. These pumps are less common but effective when installed correctly.

Understanding these types lets you choose the backup sump pump that fits your home’s infrastructure and needs best.

How Backup Systems Work

A backup sump pump activates when the primary sump pump cannot keep pace with incoming water or loses power. Battery-powered models rely on sensors or float switches that detect rising water levels, instantly turning the backup pump on.

Water-powered systems use your household water line’s pressure to generate suction and transfer sump water out. This method is mechanical, meaning it works even if electrical power is unavailable, but it depends on continuous water supply and municipal pressure.

Both systems require installing check valves to prevent floodwater from flowing back into the sump pit. Proper setup ensures your basement remains dry in emergencies.

Why Add a Backup Sump Pump

Adding a backup sump pump provides peace of mind by safeguarding your home from costly water damage during storms or power outages. Your primary pump could fail due to mechanical issues or electrical problems; a backup pump acts as insurance.

Basements in areas like Simcoe County or York Region can face sudden water surges during heavy rains or snow melts. Relying solely on your primary pump risks flooding when it fails.

Investing in a backup sump pump reduces the risk of wet basements, mould growth, and structural damage. For reliable, professional installation and advice, Harris Plumbing has over 51 years of experience serving Ontario homeowners with sump pump solutions that combine quality and expertise.

Installing a Battery-Operated Backup Sump Pump

Installing a battery-operated backup sump pump adds security when your main pump stops or the power fails. You need to carefully place the pump to protect your sump pit and set up electrical connections correctly. Testing ensures the system works in emergencies, giving you peace of mind that your basement will stay dry.

Positioning the Backup Pump

Place the backup sump pump in the sump pit alongside your primary pump, but not so close that they interfere with each other’s operation. The backup pump should sit on a stable base, often a plastic or rubber pad, to avoid vibration damage.

Install a check valve on the discharge pipe of the backup pump to prevent water from flowing back when the pump isn’t running. This valve is critical to maintaining water flow direction and protecting the sump pit from flooding.

Make sure the pump is oriented so the discharge pipe connects properly to the existing drainage system without excessive bends, which reduce flow efficiency. Proper positioning prevents water damage and ensures smooth operation.

Connecting the Battery and Charger

Use a deep-cycle 12-volt battery designed for backup sump pumps. Before connecting, wrap the battery in plastic to protect it from moisture and place it on a secured shelf near the sump pit.

Connect the pump to the battery using low-voltage cables, ensuring all terminals are tight and corrosion-free. Then, plug the charger into a dedicated electrical outlet to keep the battery fully charged at all times.

Install the charger where it can easily be monitored, as maintaining the battery’s charge is essential for reliable backup performance. Avoid extension cords and make sure wiring complies with local electrical codes.

Testing the Battery Backup System

After installation, simulate a power outage by unplugging the primary sump pump to see if the backup activates and pumps water efficiently. Pour water into the sump pit slowly until the backup pump turns on automatically.

Observe the pump’s cycling to confirm the battery is supplying enough power and that the check valve prevents water from returning to the pit. Listen for any unusual noises or inconsistent operation.

Test the system every six months or after any electrical work to maintain reliability. If unsure, a licensed professional like Harris Plumbing can assist with testing and maintenance, ensuring your backup sump pump functions correctly in critical situations.

Installing a Water-Powered Backup Sump Pump

A water-powered backup sump pump relies on your home’s municipal water pressure to operate when the primary pump fails. To ensure proper function, you need to mount the pump securely, connect it to the water supply, and manage the discharge flow properly. Careful attention to these elements reduces flooding risk during power outages or primary pump breakdowns.

Mounting the Pump and Setting the Float

Begin by attaching sturdy cleats or brackets to the wall above the sump pit. Use 3-inch screws to securely fasten two 2×3 cleats about three feet long each. The backup pump mounts onto these cleats using the hardware provided with your system.

Set the float switch on the backup pump slightly higher than the primary pump’s float. This positioning ensures the backup engages only when water reaches a level higher than normal operation. Proper float adjustment prevents the backup from running unnecessarily, preserving water and pump longevity. Accurate placement is critical for reliable sump pit protection.

Running Copper Pipe for Water Supply

Use copper pipe to connect the backup sump pump to your home’s cold water line. Copper is durable and resists corrosion, making it suitable for high-pressure connections. Run the pipe outside the sump pit area, fixing it securely along walls or joists to prevent movement.

Install a shut-off valve on this line for easy maintenance and emergency isolation. Add a backflow preventer to protect your potable water from contamination caused by any reverse flow. Following local plumbing codes for these fittings is essential. Proper pipe installation safeguards water flow and ensures the pump can activate instantly during emergencies.

Connecting the Discharge and Check Valve

Attach the discharge pipe from the backup pump to the sump pit’s drainage system or an approved outdoor outlet. Installing a check valve on the discharge line prevents water from flowing back into the sump pit, which could cause the pump to cycle unnecessarily or flood your basement.

Use materials rated for wet environments and ensure tight, leak-free joints. Position the check valve vertically or per manufacturer instructions for optimal performance. Confirm the discharge route complies with local regulations, avoiding damage to foundations or landscaping. Proper connection of the discharge and check valve ensures efficient removal of water and reliable backup pump operation.

For expert assistance with installation, especially in Ontario’s Simcoe County or York Region, contacting Harris Plumbing ensures your backup sump pump is mounted and connected to the highest standards.

Connecting Discharge and Suction Lines

Properly connecting the discharge and suction lines is crucial for your backup sump pump to function effectively and prevent basement flooding. You’ll need to measure, cut, and securely attach PVC pipes with precise fittings to avoid leaks and ensure reliable water flow.

Measuring and Cutting PVC Pipe

Start by accurately measuring the length of PVC pipe you'll need for both the suction and discharge lines. Measure from the sump pump outlet to the discharge point outside your home, allowing extra length for fittings and bends.

Use a fine-tooth saw or PVC cutter to make clean, straight cuts. Uneven edges can cause leaks or poor connections. Deburr the ends with a utility knife or sandpaper to remove any rough edges or burrs.

It’s important to double-check measurements before cutting. Using flexible PVC pipe can help adjust for slight inaccuracies, but rigid piping must fit perfectly to avoid strain on joints.

Attaching the Discharge Pipe

Attach one end of the discharge pipe firmly to your backup sump pump outlet. Use PVC primer and cement to create a watertight bond on the pipe and fittings. Apply primer first, then cement while twisting the pieces slightly to ensure full coverage.

Route the discharge pipe outdoors, directing water away from your foundation by at least 1.5 metres to avoid groundwater re-entry. Ensure proper slope to encourage gravity drainage.

If your setup uses a check valve, install it between the pump and discharge pipe. This prevents water from flowing back into the sump pit when the pump is off.

Securing Connections and Fittings

After attaching the pipes, secure all connections with appropriate PVC fittings and clamps. Use pipe straps to fasten the discharge and suction lines to wall studs or joists, keeping pipes stable and reducing movement.

Check all fittings for tightness, especially near elbows and tees, to prevent leaks or separation under pressure. Follow local plumbing codes that apply to your area in Ontario or Barrie when installing backflow preventers or shut-off valves.

If you’re unsure about complex connections, consider consulting a licensed journeyman plumber from Harris Plumbing to guarantee system integrity and compliance with regional standards.

Final Steps and Maintenance Tips

Properly finishing your backup sump pump installation involves thorough testing to ensure both your primary and backup pumps operate reliably. Regular maintenance is essential to prevent failure during critical moments and to extend the lifespan of your system.

Testing Both Primary and Backup Pumps

Start by filling the sump pit with water to activate your primary sump pump. Observe if it turns on promptly and efficiently pumps water out of the pit. If it doesn’t, check for blockages or electrical issues immediately.

Next, test the backup sump pump. For a battery-operated system, disconnect the main power supply to simulate an outage. The backup pump should run smoothly on battery power without delay. If you use a water-powered backup, verify its connection and flow pressure.

Verify that the check valve on the discharge pipe is secure to prevent backflow to your sump pit. Testing ensures both pumps will protect your basement from flooding, especially during power failures or primary pump malfunctions.

Routine Maintenance Checklist

Keep the sump pit clean by removing debris, sediment, and dirt regularly. Check both pumps for signs of wear or damage every six months, focusing on the float switch and discharge pipes.

Test the battery backup system monthly. Ensure the battery is fully charged and replace it every 2 to 3 years or as recommended by the manufacturer. For water-powered backups, inspect the water supply line and valve for any leaks or corrosion.

Lubricate moving parts if specified in the pump’s manual. Inspect and tighten all electrical connections. Scheduling annual professional service, like the ones Harris Plumbing offers in Simcoe County or York Region, can catch potential issues before they cause flooding.
