Your Home’s Flood Insurance: The Backup Sump Pump Buying Guide
A sump pump is your basement’s first line of defense against water. But what happens when the main pump fails, or the power goes out during a storm? That’s where a backup sump pump shines. It’s like a trusty sidekick, ready to jump in when your primary hero needs a break. This guide will help you pick the right one to keep your basement dry and your home safe.
1. Key Features to Look For
When you’re shopping for a backup sump pump, keep these important features in mind:
Power Source
- Battery Backup: This is the most common type. It runs on a deep-cycle battery, similar to what’s in a car but designed for longer, slower power use. You’ll need a battery and charger, which are often sold separately.
- Water-Powered: These pumps use your home’s water pressure to work. They don’t need electricity or batteries. They’re a good eco-friendly option, but their pumping power depends on your home’s water pressure.
Pumping Capacity (Gallons Per Hour – GPH)**
- This tells you how much water the pump can move in an hour. More GPH means it can handle more water.
- Match the GPH to your main sump pump’s capacity. A good rule of thumb is to get a backup with at least 50% of your main pump’s GPH.
Float Switch Type**
- Vertical Float Switch: This is a common type. It’s attached to a tether and floats up with the water level.
- Diaphragm Float Switch: This type is sealed and less likely to get stuck. It’s a more reliable option.
Construction Material**
- Cast Iron: Very durable and resistant to corrosion. These pumps last a long time.
- Thermoplastic: Lighter and often more affordable. Good for lighter-duty use.
Alarm System**
- Many backup pumps come with an alarm that sounds if the water level gets too high or if the battery is low. This gives you an early warning.
2. Important Materials
The materials used in a backup sump pump affect its durability and performance.
- Impeller: This is the part that spins to move water. Look for pumps with durable impellers, often made of strong plastic or metal.
- Housing: The outer shell protects the motor. Cast iron is excellent for strength and longevity. Stainless steel is also a good choice for corrosion resistance.
- Seals: Good seals prevent water from leaking into the motor. Rubber or Buna-N seals are common and effective.
3. Factors That Improve or Reduce Quality
Several things can make a backup sump pump better or worse.
What Makes a Pump Better?**
- Solid Construction: Pumps made with high-quality materials like cast iron or stainless steel tend to last longer.
- Reliable Float Switch: A float switch that doesn’t get stuck is crucial for the pump to activate when needed.
- Good Warranty: A longer warranty often means the manufacturer stands behind their product.
- Positive Reviews: What other users say about a pump’s performance and reliability is valuable information.
What Can Make a Pump Worse?**
- Cheap Plastic Parts: These can break or wear out quickly.
- Prone-to-Sticking Float Switches: If the switch gets jammed, the pump won’t turn on.
- Overheating Motor: A motor that overheats can stop working. Look for pumps with thermal overload protection.
- Poorly Designed Housing: If the pump isn’t sealed well, water can damage the motor.
4. User Experience and Use Cases
Using a backup sump pump is pretty straightforward. Once installed, it mostly works on its own.
Ease of Installation**
- Most battery backup systems are designed for DIY installation. They usually involve connecting the pump to your existing sump pit and hooking up the battery and charger.
- Water-powered pumps might require some plumbing knowledge.
When You’ll Need It**
- Heavy Rainstorms: These are the most common times your main pump will work overtime.
- Power Outages: During storms, power lines can go down. Your backup pump keeps working without electricity.
- Main Pump Failure: Pumps don’t last forever. A backup protects you if your main pump suddenly stops working.
- High Water Tables: If your groundwater level is naturally high, a backup pump provides extra security.
