This comprehensive Simple Project 750W PRO Macerating Toilet review is based on hands-on testing to help you decide if this high-powered upflush system is the right solution for your home. We’ll dive deep into its performance, installation, and whether it truly lives up to the hype. If you’re wondering should I buy a Simple Project macerating toilet, you’re in the right place. For more background on these systems, check out our guide on how upflush toilets work.
What Is Simple Project 750W PRO Macerating Toilet System?
The Simple Project 750W PRO is a complete macerating (or upflush) toilet system designed for locations where traditional gravity-fed plumbing is impractical or prohibitively expensive. It’s positioned as a premium, high-capacity solution within Simple Project’s lineup, targeting homeowners and contractors looking to add a bathroom in a basement, attic, garage, or home addition. The core innovation is its 750-watt macerator pump, which grinds waste and toilet paper into a slurry and pumps it upward and away to your existing sewer or septic line. This eliminates the need for the downward slope (fall) required by standard plumbing. The brand, Simple Project, focuses on providing comprehensive and cost-effective plumbing alternatives. This particular model stands out with its four water inlets, allowing you to connect a shower, sink, or bathtub to the same unit, creating a full bathroom from a single drainage point. Our Simple Project 750W PRO Macerating Toilet review will verify if these features translate to real-world performance.
Key Features & Specifications

What’s Included in the Box

Unboxing the Simple Project 750W PRO feels like receiving a complete plumbing kit. Everything you need for the core toilet installation is thoughtfully packed. The contents include: the ceramic toilet bowl, the toilet water tank with pre-installed dual flush mechanism, the 750W macerator pump unit, a set of mounting accessories (bolts, seals, mounting plate), and a detailed installation instruction manual. The packaging is robust, with ample foam protection to prevent damage during shipping. Our first impression was positive—the ceramic components have a clean, glossy finish typical of standard toilets, and the pump unit feels solid and well-constructed. It’s important to note that while the kit is comprehensive, you will need to supply your own PVC piping for drainage connections, a water supply line, and electrical wiring to complete the installation. This is standard for macerating toilets, but it’s a key consideration when planning your Simple Project macerating toilet pros cons assessment.
How to Use Simple Project 750W PRO Macerating Toilet System: Complete Guide

Step 1: Initial Setup and Installation
Planning is crucial. Choose your location, ensuring access to a standard 120V electrical outlet, a cold water supply line, and a path for the 3/4″ or 1″ discharge pipe to your main drain. The pump must be positioned so the inlet is lower than the toilet outlet. You can mount the pump on the floor behind the toilet or frame it into a wall. Connect the toilet to the pump using the provided rubber coupling and hose clamp. Then, connect the pump’s discharge outlet to your drain pipe using PVC. Finally, connect the water supply to the tank’s fill valve.
Step 2: First-Time User Guide
Once installed, plug the unit into a GFCI outlet. The system is now powered. The toilet operates like any standard dual-flush toilet. Press the smaller button for a half flush (liquid waste) and the larger button for a full flush (solid waste). Upon flushing, you’ll hear the macerator pump activate automatically—it grinds the contents and pumps them out. The cycle lasts about 10-15 seconds.
Step 3: Core Functions and Daily Use
For daily use, it behaves identically to a regular toilet. The dual-flush system is intuitive and helps save water. The key difference is the audible but relatively quiet hum of the pump during operation. You can connect other fixtures to the additional inlets using standard plumbing fittings. For example, connecting a shower drain involves running a pipe from the shower pan to one of the pump’s inlets.
Step 4: Advanced Techniques
For optimal performance, consider connecting the vent hose to your home’s existing plumbing vent stack instead of just using the carbon filter. This provides more consistent odor removal. If installing the pump in a wall, ensure you create an access panel for future maintenance. Labeling the inlet ports if you connect multiple fixtures can help with future troubleshooting.
Step 5: Maintenance and Care
Regular maintenance is simple. Clean the ceramic bowl with standard, non-abrasive toilet cleaners. It’s recommended to use single-ply toilet paper to reduce strain on the macerator blades. Every few months, you can run a dedicated macerator cleaner or a mixture of vinegar and water through the system to break down any buildup. The activated carbon filter in the vent should be replaced every 6-12 months depending on usage. For a full maintenance schedule, read our dedicated care guide.
Step 6: Troubleshooting Common Issues
Pump won’t activate: Check power at the outlet, ensure the toilet is properly seated on the pump gasket, and verify the float switch inside the pump isn’t stuck.
Poor flushing/pumping: This could indicate a clog. First, try using a plunger on the toilet bowl. If that fails, you may need to disconnect the pump and check for a jam in the impeller (always disconnect power first!).
Unusual noise: Grinding or rattling sounds could mean a foreign object has entered the system. The pump will likely need to be inspected.

Performance & Real-World Testing

Testing Methodology
We installed the Simple Project 750W PRO in a basement bathroom rough-in, connecting it to a main sewer line approximately 25 feet away with a 10-foot vertical rise. The system was used daily by a household of three over a period of four weeks. We tested its performance with standard waste, toilet paper, and simulated occasional heavy use.
Performance Metrics
Flushing Power: Excellent. The 750W motor made quick work of all waste, and the pump consistently cleared the bowl in a single flush cycle. The dual-flush mechanism worked reliably, with a noticeable water savings from the half-flush option.
Noise Level: Surprisingly quiet for a macerator. The operational noise is a low hum, significantly quieter than many budget models. It’s not silent, but it’s unlikely to disturb conversations in adjacent rooms.
Pumping Efficiency: We encountered zero clogs or pumping failures during the test period. The system handled the vertical lift and horizontal run without any hesitation.
Real-World Scenarios
We connected a small vanity sink to one of the extra inlet ports. The pump handled simultaneous drainage from the toilet and the sink without issue. We also tested its response to heavier, “high-fiber” toilet paper, and it processed it without complaint, though we still recommend single-ply for long-term health of the blades.
Claims vs. Reality
Manufacturer claims largely held true. The pumping distance specs seem accurate based on our setup. The “quiet operation” is relative—it’s quiet for a macerating pump, but you will hear it. The four-inlet flexibility is a genuine advantage, not just a marketing point. This hands-on testing phase is the core of our Simple Project 750W PRO Macerating Toilet review, and the performance was impressive.
Pros and Cons

When to Choose This Product
Choose the Simple Project 750W PRO if you need maximum pumping power for a long or high vertical run, or if you plan to connect a shower, bathtub, and sink to the same system. It’s the best macerating toilet for basement setups that require a full bathroom suite.
When to Consider Alternatives
If you only need a toilet and a sink for a simple half-bath, and your vertical lift is under 15 feet, a less powerful (and less expensive) model like the Saniflo might suffice. Our Simple Project 750W vs alternatives analysis shows the PRO model wins on raw power and connectivity. For more detailed comparisons, see our brand showdown article.

Expert Tips for Maximum Value
Tip #1: Plan Your Drain Route Meticulously
Before buying, map the exact path from the toilet to the main drain. Minimize 90-degree elbows; use 45-degree bends where possible to reduce pumping resistance and maintain efficiency.
Tip #2: Invest in a GFCI Outlet
For safety, the pump must be plugged into a Ground Fault Circuit Interrupter (GFCI) outlet. If one isn’t nearby, factor in the cost of having an electrician install one.
Tip #3: Use the Right Supplies
Don’t skimp on piping. Use schedule 40 PVC for all discharge connections. Having a plumbing kit with various fittings, PVC cement, and a hacksaw on hand will make installation smoother.
Tip #4: Test Before Finalizing
After connecting water and power, but before sealing everything behind walls, run multiple flushes and check all connections for leaks. It’s much easier to fix issues now.
Tip #5: Establish a Maintenance Reminder
Set a calendar reminder every 6 months to check the system, clean any filters, and consider using a pump cleaner to prevent buildup.
Tip #6: Understand What Not to Flush
Never flush feminine hygiene products, wipes (even “flushable” ones), paper towels, or grease. These are the fastest ways to cause a costly jam.
Tip #7: Leverage the Vent Connection
If possible, connecting to your home’s vent stack is superior to relying solely on the carbon filter, especially for frequent use.
Common Mistakes to Avoid
- Mistake: Not providing an access panel to the pump if wall-mounted. → Solution: Always install a removable access panel for future maintenance or repairs.
- Mistake: Using too many sharp bends in the discharge piping. → Solution: Plan a smooth, gradual pipe run to prevent clogs and pump strain.
- Mistake: Skipping the GFCI outlet for “convenience.” → Solution: This is a non-negotiable safety requirement for any electrical device near water.
- Mistake: Flushing inappropriate items. → Solution: Treat it like a septic system; only human waste and toilet paper should go in.
- Mistake: Forgetting to replace the activated carbon filter. → Solution: Mark the replacement date on the filter or set a digital reminder to ensure odor control remains effective.

Frequently Asked Questions
Is Simple Project 750W PRO Macerating Toilet System worth the money?
For the right user, absolutely. If you need its high-power pumping (over 15 ft vertical lift) or plan to connect multiple fixtures, it provides excellent value by consolidating what would otherwise require multiple pumps. For a simple half-bath with an easy run, a less expensive model may be more cost-effective.
How does it compare to a Saniflo Saniplus?
The Simple Project 750W vs alternatives like the Saniflo Saniplus shows a clear power advantage (750W vs 500W) and greater vertical pumping capacity (36 ft vs 15 ft). The Simple Project also has four inlets versus Saniflo’s three and includes a dual-flush mechanism. The Saniflo is a trusted brand with a longer track record, but the Simple Project offers more raw performance for similar money.
What’s the learning curve for beginners?
For a confident DIYer with basic plumbing and electrical experience, installation is straightforward over a weekend by carefully following the manual. For someone with no such experience, the learning curve is steep, and we’d recommend hiring a professional plumber to ensure a leak-free and code-compliant installation.
What accessories or additional items do I need?
You will need PVC pipe and fittings (1″ or 3/4″ for discharge), PVC cement, a water supply line (standard 3/8″ toilet connector), a GFCI electrical outlet, and possibly tools like a hacksaw, wrench, and level. A basic plumbing kit covers most of this.
What warranty and customer support does it offer?
Simple Project offers a 1-year limited warranty on the 750W PRO system. Customer support is accessible via email or online channels. Based on our interactions, they are responsive and helpful with technical and pre-sales questions.
Where can I buy it at the best price?
We recommend purchasing from this authorized retailer for competitive pricing, authentic products, and reliable customer service. Amazon typically offers the best price, fast shipping, and a trustworthy return policy.
Can it handle a bathroom with a bathtub?
Yes, this is one of its key advantages. One of the four inlet ports can be dedicated to a bathtub drain. The powerful 750W motor is designed to handle the larger volume of water from a tub draining, though it should be pumped separately from toilet flushes for optimal performance.
How often does the macerator blade need replacement?
With proper use (only human waste and toilet paper), the stainless steel blades should last for many years. They are not a routine maintenance item. Needing to replace them prematurely usually indicates inappropriate items have been flushed.
