Flush Up Toilet Guide: 5 Must-Know Tips for Basement Install
Installing a toilet below the main sewer line used to be a major headache, requiring extensive excavation and complex plumbing. But thanks to flush up toilets, also known as macerating toilets, you can now add a bathroom to your basement without breaking the bank or your back. These systems grind waste into a slurry and pump it upwards to the main sewer line. But before you start swinging a wrench, there are crucial things you need to know. Let’s get started.
1. Understanding Macerating Toilet Systems: The Heart of the Operation
Before we even think about tools, let’s talk about the technology behind these toilets. A macerating toilet isn’t your average porcelain throne. It’s a system that includes a special toilet bowl, a macerating unit (which houses a powerful grinder and pump), and connecting pipes.
How They Work:
- Waste Collection: The toilet flushes like a regular toilet, but instead of going straight down the drain, the waste enters the macerating unit.
- Grinding/Macerating: Inside the unit, a high-speed blade grinds the solid waste and toilet paper into a fine slurry. This is crucial because it allows the waste to be pumped through smaller diameter pipes.
- Pumping: Once macerated, a powerful pump pushes the slurry upwards and horizontally to connect with your main sewer line or septic system.
Key Considerations:
- Pump Power: The pump’s power determines the vertical and horizontal distance the waste can be pumped. Check the manufacturer’s specifications carefully. Don’t skimp here; a weak pump will lead to clogs and backups.
- Pipe Diameter: Macerating toilets use smaller diameter pipes (typically 3/4 inch or 1 inch) compared to standard toilets (3 or 4 inch). This makes installation much easier and less invasive.
- Electrical Requirements: The macerating unit requires a dedicated electrical circuit. Make sure you have a properly grounded outlet near the toilet.
My Personal Experience: I once tried to save a few bucks by buying a cheap, off-brand macerating unit. Big mistake! The pump was weak, and it clogged constantly. I ended up replacing it with a reputable brand, and the difference was night and day. Lesson learned: quality matters!
Data Point: A study by the Plumbing-Heating-Cooling Contractors Association (PHCC) found that using a properly sized and installed macerating toilet system reduces the risk of sewage backups by up to 80% compared to using a standard toilet with a sump pump.
Technical Specifications:
| Specification | Value | Importance |
|---|---|---|
| Vertical Pumping Height | Typically 10-18 feet | Determines suitability for basement depth |
| Horizontal Pumping Distance | Typically 100-150 feet | Dictates placement flexibility |
| Pipe Diameter | 3/4 inch or 1 inch | Affects flow rate and potential for clogging |
| Power Requirements | 120V, 15 amp dedicated circuit | Ensures adequate power supply for the pump |
| Noise Level | Typically 50-60 dB during operation | Consider noise sensitivity of the surrounding area |
| Water Consumption | 1.28 gallons per flush (GPF) or less | Meets water conservation standards |
2. Choosing the Right Macerating Toilet: Not All Thrones Are Created Equal
Now that you understand how these systems work, let’s talk about choosing the right one for your needs. The market is flooded with options, so it’s important to do your research.
Factors to Consider:
- Pumping Distance: As mentioned earlier, the vertical and horizontal pumping distance is crucial. Measure the distance from your toilet location to the main sewer line and choose a system that exceeds these distances. Always add a safety margin – better to have too much power than not enough.
- Fixture Compatibility: Some macerating units can handle multiple fixtures, such as a sink and shower, in addition to the toilet. If you plan on adding a full bathroom, choose a unit that can handle the extra load.
- Noise Level: Macerating units can be noisy, especially during the grinding and pumping cycles. Look for models that are designed for quiet operation. Check customer reviews for feedback on noise levels.
- Ease of Installation: Some systems are easier to install than others. Consider your DIY skills and choose a system that you feel comfortable installing.
- Brand Reputation and Warranty: Stick with reputable brands that offer good warranties and customer support. This will give you peace of mind knowing that you can get help if you run into problems.
Types of Macerating Toilets:
- Integrated Systems: These systems have the macerating unit built directly into the toilet. They are typically more compact and easier to install.
- Separate Systems: These systems have a separate macerating unit that sits behind the toilet. They offer more flexibility in terms of placement and fixture compatibility.
Case Study: I helped a friend install a basement bathroom in his old Victorian house. He opted for a separate system because he wanted to connect a sink and shower to the same unit. The installation was a bit more complex, but the end result was a fully functional bathroom without any major plumbing overhauls.
Technical Requirements:
| Requirement | Description | Importance |
|---|---|---|
| Flow Rate | Measured in gallons per minute (GPM), indicates the volume of waste the pump can handle. | Ensures efficient waste removal and prevents backups. A higher GPM rating is generally better, especially if you plan to connect multiple fixtures. |
| Motor Horsepower (HP) | Indicates the power of the macerating pump. | Determines the pump’s ability to grind and pump waste effectively. Choose a higher HP rating for longer pumping distances and heavier usage. |
| Solids Handling | Indicates the maximum size of solid waste the macerator can handle. | Prevents clogs and damage to the macerating unit. Look for a system that can handle a variety of solid waste, including toilet paper. |
| Backflow Prevention | Includes a check valve to prevent waste from flowing back into the toilet. | Protects your water supply from contamination and ensures proper waste disposal. This is a critical safety feature. |
| Overload Protection | Includes a thermal overload switch to protect the motor from overheating. | Extends the life of the macerating unit and prevents damage from electrical surges or excessive use. |
| Certification | Look for certifications from organizations like IAPMO (International Association of Plumbing and Mechanical Officials) or CSA (Canadian Standards Association). | Ensures the system meets safety and performance standards. These certifications indicate that the system has been tested and approved for use. |
3. Planning Your Plumbing Layout: Measure Twice, Cut Once
Okay, you’ve got your macerating toilet in hand. Now it’s time to plan your plumbing layout. This is where careful planning can save you a lot of time and frustration.
Key Considerations:
- Slope: While macerating toilets can pump waste upwards, it’s still important to maintain a slight downward slope in the horizontal drain lines to ensure proper drainage. Aim for a slope of at least 1/4 inch per foot.
- Ventilation: Proper ventilation is essential to prevent sewer gases from entering your home. Connect the toilet’s vent pipe to an existing vent stack or install a dedicated vent pipe that extends through the roof. Check local building codes for specific ventilation requirements.
- Accessibility: Make sure the macerating unit is easily accessible for maintenance and repairs. Don’t bury it behind a wall or under a pile of boxes.
- Code Compliance: Always check your local building codes before starting any plumbing work. You may need a permit, and there may be specific requirements for macerating toilet installations.
My Pro Tip: Use a laser level to ensure that your drain lines have the correct slope. This will help prevent clogs and ensure proper drainage.
