Dealing with basement flooding or sewage backup isn’t just messy—it’s a health hazard and a homeowner’s nightmare. If you’re looking for a dependable, easy-to-install solution that handles wastewater efficiently, the Everbilt 1/2 HP Submersible Pre-Plumbed Sewage Basin Systemmight be exactly what you need. Designed for residential use, this all-in-one system combines performance, durability, and smart engineering to keep your home dry and safe—even during heavy rains or system overloads.
What Is the Everbilt 1/2 HP Submersible Pre-Plumbed Sewage Basin System?
TheEverbilt 1/2 HP Submersible Pre-Plumbed Sewage Basin System is a complete wastewater management unit designed for homes with below-grade bathrooms, laundry rooms, or utility sinks. Unlike standard sump pumps that only handle clean water, this system is built to manage raw sewage and solid waste up to 2 inches in diameter, making it ideal for full bathroom installations in basements.
Key components include:
A 1/2 HP cast iron submersible sewage pump
A 22-gallon polyethylene basin
Pre-installed plumbing with a 2″ discharge and check valve
Integrated alarm system (on select models)
UL-listed and CSA-certified for safety
This “pre-plumbed” feature means much of the piping is already assembled—cutting installation time by up to 40% compared to DIY setups, according to plumbing contractors surveyed by HomeAdvisor in 2024.
Why Choose a Pre-Plumbed Sewage System Over a Standard Pump?
Homeowners often wonder: “Can’t I just use a regular sump pump?” The short answer: no—and here’s why.
As noted by the International Association of Plumbing and Mechanical Officials (IAPMO), using non-sewage-rated pumps for wastewater violates plumbing codes in most U.S. jurisdictions and can void home insurance claims.
💡 Pro Tip: Sewage systems like Everbilt’s are engineered to prevent sewer gas backflow—a serious health risk often overlooked by DIYers using incorrect pumps.
How Does It Work? A Step-by-Step Breakdown
Understanding how the system operates helps you troubleshoot and maintain it properly. Here’s how the Everbilt 1/2 HP Submersible Pre-Plumbed Sewage Basin System functions:
Wastewater enters the basin from toilets, sinks, or showers via gravity-fed drain lines (typically 2″ PVC).
Float switch activates when water reaches ~10 inches—triggering the 1/2 HP pump.
Pump grinds and lifts solids and liquid up through the pre-installed 2″ discharge pipe.
Check valve prevents backflow, ensuring sewage doesn’t re-enter the basin after pumping.
Water exits to the main sewer line or septic tank, usually located above basement level.
System resets automatically once the basin is empty (~2–3 gallons residual).
The pump delivers 2,200 GPH (gallons per hour) at 10 feet of head lift, sufficient for most single-bathroom basement setups. For reference, a standard toilet flush uses 1.6 gallons—so this system can handle over 1,300 flushes per hour under optimal conditions.
Installation Guide: What You Need to Know
While “pre-plumbed” simplifies setup, professional installation is strongly recommended. However, if you’re a skilled DIYer, here’s a high-level overview:
Tools & Materials Required:
PVC primer & cement
2″ PVC pipe & fittings (if extending discharge)
Screwdriver, level, tape measure
Electrical outlet (GFCI-protected, 115V)
Permits (check local codes)
Key Steps:
Place the basin in a 24″ x 24″ concrete-cut opening (or existing pit). Ensure it’s level.
Connect inlet pipes from your fixtures to the basin’s 2″ inlet ports (use no-hub couplings if needed).
Extend the discharge pipe vertically ≥12″ above basin rim, then run horizontally to main sewer line.
Wire the pump to a dedicated GFCI circuit—never use an extension cord.
Test the system: Flush a toilet or pour 5 gallons of water into the basin. The pump should activate within 30 seconds and stop once empty.
⚠️ Warning: Improper electrical or venting setup can cause sewer gas leaks or pump burnout. The EPA emphasizes proper venting in all sewage systems to prevent hazardous gas accumulation.
Pros and Cons: Is It Right for You?
✅ Advantages
All-in-one kit reduces guesswork and material costs
Cast iron impeller resists corrosion and handles solids reliably
Quiet operation (~65 dB)—much quieter than older plastic pumps
Energy efficient: Uses ~500 watts, costing ~$1.20/month with average use
Backed by Everbilt’s 3-year warranty (longer than many competitors)
❌ Limitations
Not for high-volume use: Max 2 fixtures recommended (e.g., toilet + sink)
Head lift limit: Performance drops beyond 15 feet vertical lift
No battery backup: Add a separate alarm system for power outages
Not for commercial use: Designed strictly for residential applications
According to a 2023 Consumer Reports analysis of sewage ejector pumps, Everbilt ranked in the top 3 for value and reliability among sub-$400 systems—beating brands like Zoeller in ease of installation.
Maintenance Tips to Extend Lifespan
With proper care, this system can last 7–10 years. Follow these best practices:
Inspect quarterly: Remove debris from the basin; check for clogs in the inlet.
Clean the float switch every 6 months—soap scum can cause sticking.
Test the alarm (if equipped) monthly by pouring water until it triggers.
Replace the check valve every 3–5 years to prevent backflow wear.
Never flush non-biodegradables (wipes, paper towels)—they clog impellers.
Ignoring maintenance is the #1 cause of premature failure. A study by the National Association of Home Builders (NAHB) found that 68% of sewage pump failures were due to solid buildup or switch malfunction—both preventable.
FAQ Section
Q: Can this system handle toilet paper and human waste?
A: Yes. The 1/2 HP cast iron impeller grinds and pumps solids up to 2 inches, including standard toilet paper and waste. Avoid “flushable” wipes—they are a leading cause of clogs.
Q: Does it come with an alarm?
A: Some models (e.g., Everbilt Model #SWS50-PP) include a high-water alarm. Check the product label or retailer specs. If not, you can add a universal sewage alarm for ~$35.
Q: What’s the difference between a sewage pump and a grinder pump?
A: Grinder pumps pulverize waste into slurry (for small-diameter pipes), while sewage pumps like Everbilt’s move solids intact. Use a grinder only if required by local code or long-distance pumping (>50 ft).
Q: Can I install it myself?
A: Technically yes—but most municipalities require a licensed plumber to sign off due to health and code compliance. DIY errors can lead to fines or system failure.
Q: How loud is it during operation?
A: Around 65 decibels—similar to a normal conversation. Since it’s submerged and runs briefly (2–5 minutes per cycle), noise is rarely an issue in finished basements.
Q: Is it compatible with septic systems?
A: Yes, as long as the discharge line connects properly to your septic tank inlet. Ensure your septic system is sized for the additional load.
Conclusion: A Smart Investment for Basement Peace of Mind
