Continue reading to grasp the methods for preserving a moisture-free lower level of your house and preventing expensive damage due to dampness.
Why Do You Need a Backup Sump Pump?
A sump pump is a device designed to extract groundwater or surface water from a substructure or crawl space. This is a crucial system in the home designed to ensure dry conditions and avoid water accumulation in these lower-level areas.
However, sump pumps run on electricity. If your power goes out, your primary AC-powered sump pump will be unable to run, leaving your lower ground floor susceptible to excessive water accumulation.
That’s where a battery-operated sump pump comes in. A backup pump provides power to the sump pump when electricity is cut off. This ensures you that your pump will keep working even in a blackout.
Key reasons every homeowner needs a backup drainage pump include:
- Prevent expensive harm to basement contents, flooring, walls, etc. from moisture and leaks during a power cut.
- Avoid flooding if your primary AC sump pump fails or malfunctions
- Protection if heavy rains overload your main pump
- Redundancy if your main pump needs repairs or replacement
- Continued drainage even if the primary sump pump cord or power source becomes disconnected
- Peace of mind knowing your lower ground floor is protected 24/7 against water
Installing a backup system is the sole solution to thoroughly safeguarding your basement from water intrusion during an electricity failure.
How Does a Battery Backup Sump Pump Work?
A battery-operated sump pump works by providing power to your primary AC sump pump during a power failure. Here is an overview of how the systems work:
- The system consists of a DC battery-powered backup pump, battery, power adapter, and alarm/control system.
- The backup pump and float switch are positioned adjacent to your main AC sump pump in your sump basin.
- The battery is connected to a device that ensures it remains fully powered at all times.
- When the power goes out, the battery kicks in to run the pump when water levels rise.
- The backup pump pushes water out of the sump basin through a discharge pipe.
- A signal will sound to alert you if the pump activates due to high water.
- Once power is restored, the battery recharges, and the system returns to standby mode.
Backup pumps are designed to automatically switch over to a power accumulator when the main pump loses power. Quality pumps can pump out up to tens of thousands of gallons on a fully charged battery.
Setting up a complete recovery system provides protection 24 hours a day against water accumulation in the basement..
What to Look for in a Backup Sump Pump
When selecting a backup sump pump for your home, there are a few key features to look for:
- Power: Look for 1/3 HP or higher to match your primary pump’s strength. The pump needs to keep up with water inflow during power loss.
- Battery: A 7AH or larger sealed lead acid battery is ideal for longer runtimes. Look for batteries rated for sump pump use.
- Battery life: Get a pump with a battery that provides at least 8 hours of runtime. Some can last for days to handle extended outages.
- Charger: Select a pump that features an automatic float system, ensuring the battery remains at maximum capacity.
- Alarm: Audible and visual signals alert you if the auxiliary pumping unit is activated. This indicates a problem with your main pump.
- Automatic switchover: The system should automatically switch to battery backup power when the main pump loses AC power.
- Reviews: Choose a reliable brand with excellent reviews and feedback from property owners. Look for at least a 1-year warranty.
Follow these tips and look for the best sump pump backup system you can afford for your home and basement size. By doing so, you ensure the highest level of safeguard against moisture-related harm.
Where to Install a Battery-powered Pump
The location where you position your backup fluid handling system is crucial for its optimal functioning. Here are some guidelines on the ideal placement:
- Position the pump and float sensor next to your main pump in your sump pit. It should be mounted at the same height as your main pump.
- The pump needs to sit upright on a solid base. Make sure the inlet screen is 6 inches or more from the bottom of the sump basin so it won’t suck up sediment.
- Position the device that detects liquid levels in a way that it can ascend and descend without any hindrance.
- Run the discharge pipe separately from your main pump’s line. Join them together outside the home or at the discharge line.
- Place the battery box on a shelf or elevated surface close to the sump pit. Elevation helps improve battery lifespan.
- Put the charger up high where it won’t risk getting wet.
Ensuring the correct setting up of the auxiliary water system components guarantees effective drainage and triggers the process when necessary.
How to Implement a Battery Backup Sump Pump
Establishing a backup drainage pump setup takes some mechanical aptitude but is a straightforward DIY project for many homeowners. Here is an overview of backup sump pump installation steps:
Gather Tools and Materials
You will need a drill, screwdriver, pliers, PVC cement and primer, pipe clamps, and possibly an extension cable. Make sure you have all parts, including discharge hose or piping, hose clamps, and necessary adapters.
Mount the Backup Pump
Position your pump in the sump basin next to the primary pump and secure it in place with a base or bricks. Ensure the correct float sensor height.
