Let’s Talk About DOMETIC 385345889 Floor Flange 3″ MPT
The DOMETIC 385345889 Floor Flange 3″ MPT isn’t exactly the kind of gear that gets the blood pumping like a new hunting rifle or a high-tech GPS watch. However, when you’re dealing with the less glamorous, but equally essential, aspects of mobile living, like sanitation systems in RVs or boats, reliability is king. Dometic, a respected name in the RV and marine industry, offers this floor flange as a service part for their toilets, promising a secure and leak-free connection.
My journey to this particular product started with a persistent leak in my campervan’s toilet. Replacing the entire toilet seemed excessive, and I suspected the issue stemmed from a failing flange. After some research, the DOMETIC 385345889 Floor Flange 3″ MPT emerged as a direct replacement part, theoretically guaranteeing compatibility and ease of installation.
Upon receiving the package, my initial impression was… functional. It’s a black plastic flange; aesthetics aren’t really a factor. The plastic felt reasonably sturdy, although I wouldn’t describe it as heavy-duty. The build quality appeared consistent with what I’d expect from a Dometic product – no obvious flaws or manufacturing defects.
Compared to generic floor flanges I’ve encountered at local hardware stores, this Dometic flange appears to be of a higher quality plastic. Generic options often seem brittle and prone to cracking, particularly under stress. I opted for the DOMETIC 385345889 Floor Flange 3″ MPT primarily for its guaranteed compatibility with my toilet model and the perceived reliability of the Dometic brand.
My first impression was cautiously optimistic. While a floor flange might not inspire unbridled excitement, knowing I had a potential solution to a messy problem brought a sense of relief. Now, to see if it lives up to the Dometic name.
Real-World Testing: Putting DOMETIC 385345889 Floor Flange 3″ MPT to the Test
First Use Experience
My test environment was the confined space of my campervan’s wet bath. Installation involved disconnecting the old flange, cleaning the surrounding area, and carefully fitting the new DOMETIC 385345889 Floor Flange 3″ MPT into place. The 3″ MPT (Male Pipe Thread) connected seamlessly to the existing plumbing.
The initial installation was surprisingly straightforward. The flange sat flush against the floor, providing a solid base for the toilet. After reconnecting the water supply and running a few flushes, I was relieved to find no leaks.
However, I initially overtightened the bolts securing the toilet to the flange. This resulted in a slight warping of the plastic flange. After loosening the bolts slightly, the warping disappeared and the seal remained intact.
Extended Use & Reliability
After several months of regular use during various camping trips, the DOMETIC 385345889 Floor Flange 3″ MPT has held up admirably. There are no signs of cracking or deformation, despite the temperature fluctuations and occasional jostling associated with off-road travel. Maintenance is virtually non-existent; a quick wipe-down with a damp cloth is all that’s required.
The plastic material has proven resistant to staining and degradation from typical toilet chemicals. Compared to the previous, failing flange, this Dometic replacement offers a noticeable improvement in stability and leak resistance. It has definitely outperformed my expectations for a seemingly simple component.
