Got a bathroom remodel on the horizon or plumbing that’s giving you trouble? A rear discharge toilet might be the solution. This guide covers everything you need to know about these unique fixtures, whether you’re a seasoned plumber or a DIY enthusiast. We’ll explore what sets them apart, how to install them, potential problems, maintenance tips, and comparisons to other toilet types. Let’s dive in!
Understanding Rear Discharge Toilets
Rear discharge toilets, also known as back outlet or horizontal outlet toilets, expel waste horizontally into a pipe concealed within the wall behind them. This contrasts with standard toilets that discharge downwards through the floor. This design offers unique advantages, especially in situations where traditional plumbing is impractical.
Advantages of Rear Discharge Toilets
These toilets offer several benefits:
- Design Flexibility: Ideal for renovations or additions where rerouting floor plumbing is expensive or disruptive. They allow for more flexible bathroom layouts.
- Concealed Plumbing: Provides a cleaner, more modern aesthetic by hiding unsightly pipes.
- Cost-Effective Solution (in some cases): Can be more cost-effective than extensive plumbing rerouting in renovations.
Disadvantages of Rear Discharge Toilets
While advantageous, they also have potential drawbacks:
- Complex Installation: Requires precise measurements and can be more challenging than installing a standard toilet. Professional installation is often recommended.
- Potential Noise: Pressure-assisted models, common with rear discharge toilets, can produce a louder flush.
- Specific Rough-in: Requires a specific rough-in measurement, limiting toilet model choices.
Pressure-Assisted vs. Gravity-Fed Flushing Systems
Rear discharge toilets typically use one of two flushing systems:
- Pressure-Assisted: Uses compressed air for a powerful, efficient flush. However, these systems can be louder.
- Gravity-Fed: Relies on gravity for a quieter flush, but may not be as forceful. Some newer models are combining pressure-assisted power with noise-reduction technology.
The best choice depends on your preference for flushing power versus noise level.
Installation: A Step-by-Step Guide
Proper installation is crucial for rear discharge toilets. Here’s a general overview, but always consult the manufacturer’s instructions:
- Measure the Rough-in: Accurately measure the distance from the finished wall to the center of the drainpipe. This measurement is critical for selecting the correct toilet model.
- Prepare the Drainpipe: Ensure the drainpipe is properly positioned and secured within the wall.
- Install the Toilet Flange: Secure the toilet flange to the drainpipe, ensuring a level and stable base for the toilet.
- Position the Toilet: Carefully position the toilet onto the flange, aligning the outlet with the drainpipe.
- Secure the Toilet: Bolt the toilet to the flange, ensuring it’s firmly in place.
- Connect the Water Supply: Connect the water supply line to the toilet tank.
- Test for Leaks: Thoroughly test for leaks around the base and tank connections.
Professional installation is highly recommended to avoid potential problems.
Troubleshooting Common Issues
Even with proper installation, issues can arise. Here are some common problems and solutions:
- Clogs: Often resolved with a plunger or toilet auger.
- Leaks: Usually occur around the tank or connections. Tightening connections or replacing worn parts often fixes the problem. Leaks from the concealed cistern may require professional help to access.
- Running Water: This could indicate a faulty fill valve or flapper. Why does the back of my toilet keep draining?
For persistent issues or complex repairs (like a cracked tank), consult a plumber.
Maintenance: Keeping Your Toilet in Top Shape
Regular maintenance can prevent problems:
- Check for Leaks: Regularly inspect for leaks around the base, tank, and connections.
- Clean with Gentle Cleaners: Avoid harsh chemicals, which can damage seals. Use standard toilet bowl cleaner and a brush.
- Inspect and Replace Parts: Periodically inspect the flapper and fill valve for wear and replace as needed.
Comparing Toilet Types
How do rear discharge toilets stack up against other types?
- Rear Discharge: Offer design flexibility and concealed plumbing, but may have specialized installation and potential noise.
- Standard (Floor-Mounted): Simpler installation, but less design flexibility.
- Wall-Hung: Maximizes floor space and offers a modern look, but is the most expensive to install.
The best choice depends on your bathroom layout, budget, and preferences. Consider space constraints and the difficulty of accessing plumbing for repairs when making your decision.
Choosing the Right Rear Discharge Toilet
Selecting the right toilet can feel overwhelming. Consider these factors:
- Bathroom Style: Choose a toilet that complements your bathroom’s aesthetics.
- Budget: Rear discharge toilets vary in price. Set a budget and stick to it.
- Flush Power: Decide between pressure-assisted (powerful but louder) and gravity-fed (quieter but less powerful).
- Reviews: Read online reviews to gain insights from other homeowners.
| Feature | Rear Discharge | Standard (Floor Discharge) | Wall-Hung |
|---|---|---|---|
| Drain Direction | Horizontal (Through Wall) | Vertical (Through Floor) | Horizontal (Through Wall) |
| Flushing System | Usually Pressure-Assisted | Gravity-Fed | Gravity-Fed or Pressure-Assisted |
| Installation | More Complex | Simpler | Most Complex |
| Noise Level | Can be Louder | Quieter | Varies |
| Ideal For | Renovations, High-Rises | Most Residential Homes | Modern Designs |
By considering these factors, you can find the perfect rear discharge toilet for your needs.
The Future of Toilets
Smart toilets with integrated bidets and advanced flushing systems are gaining popularity. As homeowners seek greater flexibility in bathroom renovations, rear discharge toilets are likely to become even more prevalent. They represent a modern, practical solution to plumbing challenges.
What are the disadvantages of a back to wall toilet?
Back to wall toilets offer a sleek, minimalist look, but it’s essential to understand the potential downsides:
- Higher Cost: Often significantly more expensive than standard toilets, both in terms of the unit itself and installation.
- Complex Installation: Often requires rerouting plumbing, modifying wall structures, and building a support frame. This complexity adds to the cost and time involved in installation. What is a rear discharge toilet? may provide additional context.
- Difficult Maintenance: The concealed cistern can be hard to access for repairs, leading to higher maintenance costs and inconvenience.
- Space Considerations: While the toilet itself may save space, the concealed cistern and framework can sometimes take up more overall space, especially in smaller bathrooms.
- Hidden Leaks: Leaks in the concealed cistern can go undetected, potentially causing significant water damage before being discovered.
Carefully weigh these disadvantages against the aesthetic benefits before making a decision.
Why does the back of my toilet keep draining?
If your toilet tank seems to be constantly draining, the problem is likely not the back of the toilet but rather water leaking from the tank into the bowl. This triggers the fill valve to constantly refill the tank. Here’s how to troubleshoot and fix it:
- Check the Flapper: A worn or damaged flapper is the most common cause. Perform a dye test to confirm.
- Inspect the Fill Valve: A malfunctioning fill valve can also cause continuous draining. Check the water level and look for leaks.
- Examine the Chain: A tangled or too-long chain can prevent the flapper from sealing properly.
- Check for Cracks (Rare): Although less common, a cracked tank or bowl can cause leaks.
Solutions often involve replacing the flapper or fill valve, both relatively simple DIY tasks. For cracks or complex issues, consult a plumber.
