Upflush Shower System: Pros & Cons for Woodshop Plumbing (Expert Tips)

As the leaves turn and the air grows crisp, my thoughts invariably drift to the scent of woodsmoke and the satisfying crackle of a well-laid fire. Autumn is the time when many of us working with wood – whether in professional logging, small-scale firewood businesses, or even dedicated hobbyists – start thinking seriously about heating our workshops and homes for the coming winter. And that often leads to questions about improving our facilities, including adding conveniences like a shower.

Now, you might be thinking, “What does a shower have to do with wood processing?” Well, after a long day felling trees, hauling logs, or wrestling with a stubborn log splitter, a hot shower is a welcome luxury. But when your woodshop is located in a place where traditional plumbing isn’t easily accessible, things get tricky. That’s where upflush shower systems come in.

Upflush Shower Systems: Pros & Cons for Woodshop Plumbing (Expert Tips)

An upflush shower system, also known as a macerating toilet and shower system, is a self-contained unit that allows you to install a bathroom in a location where traditional plumbing isn’t readily available. It works by grinding waste into a slurry and pumping it upwards to connect to an existing drain line. This is particularly useful in basements, garages, or, in our case, woodshops where running new drain lines can be costly and disruptive.

What is an Upflush Shower System?

At its core, an upflush system consists of a macerating pump, a toilet (often specially designed for the system), a shower base with a drain, and the necessary plumbing connections. The macerating pump houses a powerful motor and blades that grind solid waste into a fine slurry. This slurry is then pumped upwards through a narrow pipe to a main drain line, which can be located several feet above the system and some distance away.

Key Components:

• Macerating Pump: The heart of the system. It grinds waste and pumps it to the drain line.
• Toilet: Often a rear-discharge toilet designed to connect directly to the macerating pump.
• Shower Base: A standard shower base with a drain that connects to the pump.
• Piping: Small-diameter pipes (typically 3/4″ or 1″) used to transport the slurry to the main drain.
• Vent: A vent pipe is crucial for proper operation and preventing sewer gases from entering the space.

Example:

Saniflo is a well-known brand in the upflush toilet and shower market. Their Saniflo Saniaccess 2 is a common macerating pump. The pump can handle waste from a toilet and sink. This model can pump waste up to 15 feet vertically and 150 feet horizontally. The discharge pipe diameter is usually 3/4 or 1 inch.

Why Consider an Upflush System for Your Woodshop?

For woodworkers, loggers, and firewood producers, the appeal of an upflush shower system often lies in its flexibility and ease of installation. Here are a few scenarios where it might be a good fit:

• Remote Woodshops: If your woodshop is located in a building without existing plumbing, such as a barn or outbuilding, an upflush system can provide a convenient and cost-effective solution for adding a shower.
• Basement Woodshops: Many woodworkers set up shop in their basements. Upflush systems make it possible to add a bathroom without breaking through concrete floors to install traditional plumbing.
• Limited Plumbing Access: Even if you have existing plumbing, it might be inconvenient or expensive to run new drain lines to your desired shower location. An upflush system can bypass these limitations.
• Seasonal Use: If you only use your woodshop during certain times of the year, an upflush system can be a temporary or semi-permanent solution that can be easily winterized.

My Experience:

I once worked on a logging operation in a remote area of the Pacific Northwest. The crew lived in temporary housing with very limited facilities. We considered installing a series of upflush shower systems in a communal washhouse to provide a much-needed comfort for the workers. While the project ultimately didn’t go ahead due to logistical challenges, the upflush system was a viable option because it didn’t require extensive excavation or complex plumbing infrastructure.

Pros of Upflush Shower Systems

• Easy Installation: One of the biggest advantages is the relatively simple installation process. No need to break concrete or dig trenches. The system connects to existing water supply lines and a standard electrical outlet.
• Cost-Effective: Compared to traditional plumbing, upflush systems can be significantly cheaper, especially when considering the cost of excavation and labor.
• Flexibility: You can install a bathroom virtually anywhere, regardless of the existing plumbing layout.
• Space-Saving: The compact design of the system makes it ideal for small spaces.
• DIY-Friendly: With basic plumbing skills, you can often install an upflush system yourself.

Data:

According to HomeAdvisor, the average cost of installing a new bathroom in the US ranges from $5,000 to $15,000. An upflush shower system, including the unit and installation, typically costs between $1,000 and $3,000. This represents a potential cost saving of up to 80%.

Cons of Upflush Shower Systems

• Noise: The macerating pump can be quite noisy when it’s running. This can be disruptive, especially in a quiet woodshop environment.
• Maintenance: Upflush systems require regular maintenance to prevent clogs and ensure proper operation. This includes cleaning the pump and occasionally replacing parts.
• Limited Capacity: Upflush systems have a limited capacity and can’t handle large volumes of waste. This means you need to be mindful of water usage and avoid flushing anything that could clog the system.
• Dependency on Electricity: The system relies on electricity to operate. A power outage will render the shower unusable.
• Potential for Clogs: While the macerating pump grinds waste, it’s still possible for the system to clog, especially if foreign objects are flushed down the toilet or drain.
• Aesthetics: Upflush systems can sometimes look less aesthetically pleasing than traditional bathrooms. The exposed pipes and the design of the toilet can be a visual drawback for some.

My Experience:

A friend of mine installed an upflush system in his basement workshop. While he was initially thrilled with the convenience, he quickly became frustrated with the noise of the pump. He eventually had to build a soundproof enclosure around the pump to minimize the disturbance. This added extra cost and effort to the project.

My Insight:

One thing I’ve learned is that regular maintenance is key to keeping an upflush system running smoothly in a woodshop environment. I recommend cleaning the macerating pump every few months to remove any accumulated debris. This will help prevent clogs and extend the life of the system.

Wood Selection and Its Impact on Woodshop Plumbing

While seemingly unrelated, the types of wood you process in your shop can indirectly impact your plumbing system, especially if sawdust and shavings are not properly managed.

• Resinous Woods: Woods like pine, fir, and cedar contain high levels of resin. This resin can accumulate in drains and pipes over time, potentially leading to clogs.
• Hardwoods: Hardwoods like oak, maple, and cherry produce denser sawdust, which can also contribute to clogs if not properly contained.
• Treated Woods: Avoid washing any sawdust or shavings from treated woods (e.g., pressure-treated lumber) down the drain. The chemicals used in these treatments can be harmful to the environment and potentially damage the macerating pump.

Best Practices:

• Dust Collection System: Invest in a good dust collection system to minimize the amount of sawdust and shavings that end up on the floor and potentially in the drain.
• Floor Sweeping: Regularly sweep the floor to remove sawdust and shavings.
• Drain Screens: Use fine-mesh screens over all drains to catch any debris.
• Proper Disposal: Dispose of sawdust and shavings properly. Do not flush them down the toilet or drain.

Firewood Preparation and Water Usage

The process of preparing firewood can also impact water usage in your woodshop, especially if you use water to clean logs or equipment.

• Log Washing: Some firewood producers wash logs to remove dirt and debris before splitting. This can generate a significant amount of wastewater.
• Equipment Cleaning: Cleaning log splitters, chainsaws, and other equipment also requires water.

Water Conservation Tips:

• Use Water Efficiently: Avoid excessive water usage when cleaning logs or equipment.
• Collect Wastewater: Collect wastewater and dispose of it properly. Do not allow it to run into storm drains or waterways.
• Consider Alternative Cleaning Methods: Explore alternative cleaning methods that don’t require water, such as using compressed air or dry brushes.

Chainsaw Maintenance and Cleaning

Chainsaws are essential tools for logging and firewood preparation. Proper maintenance and cleaning are crucial for their performance and longevity. However, cleaning a chainsaw can introduce oils, greases, and other contaminants into your plumbing system if not done carefully.

Safe Cleaning Practices:

• Clean Outdoors: Clean your chainsaw outdoors, away from any drains or water sources.
• Use a Tray: Use a tray or container to catch any oil or debris.
• Dispose of Waste Properly: Dispose of used oil and cleaning solvents properly. Do not pour them down the drain.
• Avoid Harsh Chemicals: Avoid using harsh chemicals that can damage the chainsaw or the plumbing system.

My Experience:

I once made the mistake of cleaning my chainsaw indoors, near a drain. A small amount of oil spilled into the drain, causing a minor clog. It took me a while to clear the clog, and I learned a valuable lesson about the importance of cleaning equipment outdoors and disposing of waste properly.

Strategic Advantages of an Upflush System

Beyond the basic convenience, an upflush system can offer some strategic advantages for your wood processing operation:
