The Ultimate Buying Guide for Submersible Sump Pumps
A submersible sump pump sits right inside your sump pit. It pulls water out of your basement before it floods. Choosing the right one keeps your home dry and safe. This guide helps you pick the best pump for your needs.
Key Features to Look For
When shopping, certain features make a big difference in how well a pump works and how long it lasts.
1. Pumping Capacity (GPH)
This tells you how much water the pump moves. GPH stands for Gallons Per Hour. Bigger basements or areas with heavy rain need a higher GPH. Look for a pump that moves at least 10 GPH for every foot of depth in your pit. Always check the pump’s rating.
2. Horsepower (HP)
Horsepower measures the pump’s strength. Most homes use 1/3 HP or 1/2 HP pumps. If you have deep pits or move water a long distance, you might need a stronger 3/4 HP pump. More HP usually means faster pumping.
3. Switch Type
The switch tells the pump when to turn on.
- Float Switch: This is common. A float rises with the water level and turns the pump on.
- Pedestal Switch: This switch sits above the water line. It is easier to reach for maintenance.
4. Vertical vs. Horizontal Float
Vertical floats need less room to operate. Horizontal floats need more space in the pit but sometimes last longer because they move less.
Important Materials Matter
What a pump is made of affects its durability. Quality materials resist rust and handle debris better.
Housing and Impeller
Good pumps use strong materials. Look for heavy-duty cast iron or thermoplastic bodies. Cast iron lasts longer and handles heat better. Thermoplastic pumps are lighter and cheaper. The impeller, the part that spins the water, should also be strong. Plastic impellers work fine for clear water, but metal impellers handle small debris better.
Seals
The seals keep water out of the motor. High-quality mechanical seals are essential. These seals stop leaks and protect the motor, making the pump last many years.
Factors That Improve or Reduce Quality
Some design choices boost performance, while others lead to quick failures.
Factors That Improve Quality
- Thermal Overload Protection: This feature automatically shuts the pump off if it gets too hot. This prevents the motor from burning out.
- Corrosion Resistance: Stainless steel shafts resist rust. Pumps with good coatings handle acidic water better.
- Oil-Filled Motor: Motors filled with oil run cooler and last longer than dry motors.
Factors That Reduce Quality
- Lightweight Plastic Casing: While cheaper, thin plastic can crack under pressure or from temperature changes.
- Snap-On Switches: These can fail sooner than sealed or heavy-duty switches.
- No Check Valve Included: A check valve stops water from flowing back into the pit when the pump stops. Buying one separately adds cost and complexity.
User Experience and Use Cases
How you plan to use the pump changes what you should buy.
Typical Use Cases
Submersible pumps are perfect for typical basement flooding. They work best when fully submerged in a sump pit. They are quiet because the water muffles the sound.
Installation and Maintenance
Most submersible pumps install easily into an existing sump pit. Check the discharge pipe size; it must match your home’s plumbing (usually 1 1/4 inch or 1 1/2 inch). Maintenance involves cleaning the pit occasionally. Pumps with easy access to the switch area make this job simpler.
If you want backup power for storms, consider a battery backup system. This system works when your main power fails. Always read user reviews to see how other homeowners find the pump’s noise level and reliability.
10 Frequently Asked Questions (FAQ) About Submersible Sump Pumps
Q: What is the main difference between a submersible and a pedestal pump?
A: A submersible pump sits completely underwater in the sump pit. A pedestal pump stands outside the pit, with only the motor housing above the water. Submersible pumps are quieter.
Q: How often should I test my sump pump?
A: You should test your sump pump monthly. Pour a bucket of water into the pit to make sure the float switch turns the pump on and off correctly.
Q: Can I use a submersible pump for sewage?
A: No. Standard sump pumps handle clear water. You need a specialized sewage ejector pump for waste water or solids. Using the wrong pump will quickly damage it.
Q: What horsepower do most homeowners need?
A: Most standard residential basements work well with a 1/3 HP or 1/2 HP pump. Choose higher HP only if you pump water very high or far away.
Q: Will a submersible pump run if the power goes out?
A: No, standard pumps need electricity. You must buy a separate battery backup system if you need protection during power outages.
Q: What is a “head height”?
A: Head height is the maximum vertical distance the pump can push water. If your water needs to travel 15 feet up to exit your house, you need a pump rated for at least 15 feet of head.
Q: Are submersible pumps noisy?
A: Generally, no. Because they are underwater, the noise is greatly reduced. They are much quieter than pedestal pumps.
Q: What size sump pit do I need for a submersible pump?
A: The pit size depends on the pump’s dimensions, but most standard 10-inch or 18-inch diameter pits work fine for residential models.
Q: What does “duty cycle” mean for a sump pump?
A: Duty cycle is how long a pump can run without stopping. High-quality pumps can run continuously during heavy storms, while cheaper models might overheat if they run too long.
Q: Should I buy a cast iron or plastic pump housing?
A: Cast iron is heavier and more durable, resisting cracks and wear better over time. Plastic is lighter and cheaper, making it a good budget option for light duty.
