Steps For Installing A Battery Backup Sump Pump
Installing a battery backup sump pump is a crucial step in protecting your basement from unexpected flooding. Follow these steps to ensure a successful installation:
- First, unplug, disconnect, and remove the old sump pump from the sump pit. This will provide space for the new battery backup sump pump.
- Next, apply Teflon tape to the threads on a check valve, then tighten the valve onto the side of the new 110-volt sump pump. This check valve prevents water from flowing back into the pit after pumping.
- After that, wrap Teflon tape around the threads of the battery-powered pump. Then, tighten the battery-powered pump onto the check valve. Set both pumps into the sump pit to ensure they are properly positioned.
- Now, it’s time to create the discharge pipe. Cut a 1½-inch-diameter PVC pipe to the desired length, according to your needs. This pipe will carry the pumped water away from your basement.
- Glue together the PVC pipe and fittings, ensuring a secure connection. Connect the discharge pipe to the existing discharge pipe using stainless steel hose clamps and a rubber connector. This will ensure a tight and leak-free seal.
- For the battery aspect of the backup sump pump, set a deep-cycle 12-volt marine battery into a protective plastic box. Place the box onto a nearby shelf for easy access and protection.
- Make the low-voltage cable connections between the battery and backup pump. Ensure all connections are secure and properly insulated.
- Lastly, plug in the battery charger and the power cord for the 110-volt primary sump pump into a 110-volt electrical outlet. This will provide power to both pumps and ensure they are ready to operate when needed.
- To ensure successful installation, test the operation of the primary pump by reaching into the sump pit and lifting the flow valve until the pump starts. Repeat the same test for the battery-powered backup pump. This will verify that both pumps are functioning correctly and ready for action.
Important Considerations For Battery Backup Sump Pump Installation
Installing a battery backup sump pump:
- Requires moderate skill level and basic plumbing knowledge.
- It is crucial to follow the correct steps and ensure proper installation to protect your basement effectively.
The cost of installation:
- Typically ranges from $350 to $500.
- Includes the pump itself, materials, and any additional tools or equipment needed for installation.
Estimated time for installation:
- Around 2 to 4 hours (may vary depending on experience and basement’s sump system complexity).
Importance of battery maintenance:
- Many homeowners have experienced unexpected basement flooding due to battery failure in backup sump pump systems.
- Regularly check the battery’s condition and replace it when necessary to avoid such situations.
Battery run-time during a power outage:
- Varies depending on the battery’s power capacity (AH rating).
- On average, fully-charged battery can provide 5-7 continuous hours of pumping or 1-3 days of non-continuous pumping.
Battery selection considerations:
- Tests conducted at North Dakota State University showed that a 40 AH battery lasted less than 4 hours, while the highest-rated battery lasted around 7 hours.
- Choosing a battery with a suitable power capacity for your specific needs is essential.
Pumping capacity and demands:
- The more powerful the backup pump, the shorter the run-time of the battery.
- Consider the pumping capacity and demands of your basement when selecting a backup pump and battery.
Understanding The Run-Time Of A Battery Backup Sump Pump
The run-time of a battery backup sump pump is crucial for protecting your basement during power outages. The run-time is affected by factors such as the power capacity of the battery and the pumping capacity of the backup pump.
When fully charged, a battery can provide 5-7 hours of continuous pumping or 1-3 days of non-continuous pumping. However, it’s essential to regularly check the battery’s voltage and performance as the run-time decreases with age.
The most common type of lead-acid batteries used with sump pumps are wet-cell batteries. Over time, the lead plates in wet-cell batteries may become corroded, resulting in a decrease in voltage and the ability to hold a charge. Aging batteries may only run for 2-3 hours or less before losing power.
To determine if a battery is aging and at risk of premature failure, check the voltage between the positive and negative terminals. If the voltage is less than 12.1 volts, it indicates that the battery may not perform optimally during a rainstorm and may need replacement.
Extreme temperatures, exposure to water, or excessive humidity can also negatively affect battery life. It’s important to store batteries in a suitable environment and regularly inspect them for signs of damage or deterioration.
Frequently Asked Questions
How much does it cost to install a battery backup sump pump?
The cost of installing a battery backup sump pump typically ranges from $160 to $600 if you choose to do it yourself. However, if you prefer professional installation, the average cost of the system can be around $900, with higher estimates reaching $1,200 and lower estimates around $600. These backup sump pumps are crucial in keeping homes dry during floods, providing added security and peace of mind against water damage.
How long will a 12v battery run a sump pump?
The duration a 12v battery can power a sump pump depends on various factors. Assuming it is fully charged, a 12v battery may last around 5-7 hours of continuous usage during a power outage. However, if the pumping occurs intermittently, it can potentially provide power for 1-3 days, depending on the frequency of usage. It is important to consider these estimates as rough guidelines since specific battery capacity and the efficiency of the sump pump can vary.
How do you backup a sump pump without electricity?
One alternative method to backup a sump pump without electricity is by utilizing a battery system. A sump pump battery backup can be installed, which will automatically kick in when the power goes out. This backup system relies on a separate battery specifically designed for this purpose, ensuring that the sump pump continues to function even during a power outage. Another option is a battery-operated sump pump, which functions independently of the main electrical supply. This additional pump activates when the primary one is unable to operate, providing a reliable backup solution. Additionally, a generator can be used as a backup power source. When the electricity goes out, the generator automatically activates, providing the necessary power to operate the sump pump. Lastly, a water alarm system can serve as an early warning system. This device detects rising water levels and alerts homeowners to potential flooding, allowing them to take immediate action and prevent damage.
How can you ensure a proper installation of a battery backup sump pump for your basement?
To ensure a proper installation of a battery backup sump pump for your basement, it is crucial to follow these steps. Firstly, assess the specific needs of your basement and choose a battery backup sump pump system that is suitable for the size and water flow of your sump pit. Secondly, carefully read and follow the manufacturer’s instructions for installation, ensuring that all necessary components are included and properly fitted. Additionally, ensure that the battery is fully charged and ready for use. Test the pump regularly to ensure it is operating correctly and that the battery backup system kicks in as intended during power outages.
