LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in Review

Let’s Talk About LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in

The LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in is a seemingly simple plumbing fitting, yet it’s an essential component for any RV, camper, or mobile home plumbing system. Manufactured by LaSalle Bristol, this trap and union combination is designed to prevent sewer gases from entering the living space, all while allowing for easy disassembly and maintenance. Let’s dive into whether this seemingly mundane piece of ABS plastic can actually live up to its crucial role.

My years spent outfitting mobile shelters and customizing off-grid plumbing setups have taught me the hard way that corner-cutting on even the smallest fitting can lead to headaches – and unpleasant smells – down the line. I needed a reliable trap for a grey water system I was building in my off-grid cabin project, and the need for a quick-disconnect union was paramount for ease of winterization. That’s what drew me to the LaSalle Bristol 633220-A.

Upon unboxing (or rather, unwrapping, as it comes in minimal packaging), my initial impression was that it’s a no-frills, functional piece. The ABS plastic feels solid enough, though not exceptionally heavy-duty, and the union seemed to thread smoothly. Comparing it to a similar trap from Camco and a brass alternative I considered from a local hardware store, the LaSalle Bristol stood out because of its integrated union and competitive price. I ultimately decided on the LaSalle Bristol because it struck a balance between affordability and the essential feature of the union for easy dismantling.

Honestly, my first impression was a mix of cautious optimism and the lingering fear that something this affordable might be too good to be true. Would it leak? Would the plastic crack under pressure? Only time, and real-world testing, would tell.

Real-World Testing: Putting LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in to the Test

First Use Experience

I tested the LaSalle Bristol 633220-A as part of the grey water drain system for a sink in my off-grid cabin, a location that sees everything from sub-freezing winter temperatures to scorching summer days. Installation was straightforward, thanks to the slip joint and hub design; it connected easily to the existing drain line and the grey water tank. Under normal use, it performed flawlessly, effectively trapping odors and allowing water to drain freely.

During a particularly cold snap, I intentionally left a small amount of water in the trap to see if the ABS plastic would become brittle and crack. Thankfully, it held up remarkably well; no leaks or damage were observed. After the first week of use, I was impressed with the ease of installation and the absence of any leaks.

Extended Use & Reliability

After six months of continuous use, the LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in is still performing admirably. There are no signs of wear or tear beyond some minor surface discoloration from prolonged exposure to the grey water. Cleaning has been infrequent, as the trap seems to self-clean with regular water flow; however, when needed, the union allows for easy disassembly and inspection.

Compared to a cheaper, non-union trap I used in a previous project, the LaSalle Bristol is a significant upgrade. The ability to quickly disconnect the trap for winterization or cleaning is invaluable, saving time and preventing potential damage to the plumbing system. So far, it outperforms my expectations and is holding up much better than I initially anticipated.

Breaking Down the Features of LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in

Specifications

The LaSalle Bristol 633220-A Pattern Trap And Union 1 1/4in x 1 1/4in features a standard “P” trap design molded from ABS plastic. It includes a slip joint connection on one end for easy attachment to drain pipes and a hub connection on the other. The defining feature is the union in the center of the trap, which allows for quick disassembly without cutting or damaging the pipe.

• Material: ABS Plastic – provides a balance of durability and cost-effectiveness. ABS is resistant to chemicals commonly found in drain systems.
• Fitting Size: 1-1/4″ x 1-1/4″ – designed to fit standard RV and mobile home plumbing connections.
• Type: P-Trap with Union – a standard plumbing design with a built-in disconnect point.
• Installation: Slip Joint and Hub connections – allows for solvent welding or mechanical connection with appropriate fittings.
• Additional Feature: 1-1/2″ Continuous Waste – this refers to the standard design that helps prevent siphoning and maintain a proper water seal.

These specifications are important because they determine the trap’s compatibility, ease of installation, and overall functionality. The ABS plastic offers decent resistance to chemicals, but it may not be as robust as brass or stainless steel in extreme conditions. The union is, of course, the star feature that sets this model apart and makes it a practical choice for seasonal applications.

Performance & Functionality

The LaSalle Bristol 633220-A performs its primary function – trapping sewer gases – effectively. The water seal is maintained consistently, preventing unpleasant odors from entering the living space. The union functions smoothly, allowing for easy disassembly without leaks.

A key strength is the ease of installation and removal; the union allows for effortless winterization. One weakness might be the ABS plastic, which, while durable enough for most applications, could potentially crack under extreme stress or in harsh environments. Overall, it meets my expectations for a simple, functional P-trap with the added benefit of a union.

Design & Ergonomics

The design is straightforward and utilitarian; it’s not visually striking, but it is functional. The ABS plastic feels reasonably sturdy, and the slip joint and hub connections are well-machined. The weight is negligible, adding minimal stress to the plumbing system.

The LaSalle Bristol 633220-A is highly user-friendly. There’s no learning curve; anyone familiar with basic plumbing will find it easy to install and use.

Durability & Maintenance

With proper care, the LaSalle Bristol 633220-A should last for several years. The ABS plastic is resistant to most household chemicals, but it should be protected from extreme physical stress or prolonged exposure to direct sunlight.

Maintenance is simple; occasional cleaning to remove debris is all that’s typically required. The union makes disassembly and cleaning a breeze.

Accessories and Customization Options

The LaSalle Bristol 633220-A itself doesn’t come with any additional accessories. Customization options are limited, but it’s compatible with standard 1-1/4″ plumbing fittings, allowing for connection to different types of drain lines. The 3/4″ dishwasher spout is a notable feature, permitting connection to a dishwasher drain line if needed. While you can’t modify the trap itself, its standard connections allow you to adapt it to a wide variety of plumbing configurations.
