Why an In Line Strainer for My RV is Necessary
From my experience owning an RV, having an in line strainer installed has been a game changer. When you’re on the road or parked at a campsite, the water source isn’t always the cleanest. An in line strainer helps catch dirt, rust, and debris before the water even enters my RV’s plumbing system. This simple device protects my pipes, faucets, and appliances from clogging or damage, saving me from costly repairs down the line.
I’ve also noticed that using an in line strainer improves the overall water quality inside my RV. It filters out particles that can make water taste or smell off, making every shower, cup of coffee, or dish I wash feel fresher and cleaner. Knowing I have that extra layer of protection gives me peace of mind, especially when I’m relying on various water hookups during my travels. For me, it’s a small investment that makes a big difference in keeping my RV water system running smoothly.
My Buying Guides on In Line Strainer Rv
When I first started looking for an in line strainer for my RV, I realized there are quite a few things to consider to make the right choice. Here’s what I learned through my experience that might help you pick the best in line strainer for your RV needs.
What Is an In Line Strainer and Why Do I Need One?
An in line strainer is a device installed in the water line of your RV to filter out debris, rust, and other particles. I found it essential because it helps protect my RV’s plumbing system and appliances from clogging or damage caused by contaminants in the water supply.
Material and Build Quality
The first thing I checked was the material. Most in line strainers come in brass, stainless steel, or plastic. I prefer stainless steel or brass since they are durable and resistant to corrosion, especially because RV water systems can be exposed to different environments. Plastic models might be cheaper but tend to wear out faster.
Size and Compatibility
My RV’s water lines are usually 1/2 inch or 3/4 inch, so I made sure to buy a strainer that matched those dimensions. It’s important to check the inlet and outlet size of the strainer to ensure it fits seamlessly with your existing plumbing without needing extra adapters.
Mesh Size and Filtration Capacity
The mesh size determines how fine the particles the strainer can catch are. I went with a medium mesh size because it balanced between filtering out enough debris and not restricting water flow too much. If you want to filter very fine particles, look for a finer mesh, but keep in mind it might need more frequent cleaning.
Ease of Installation and Maintenance
I opted for a model that was easy to install myself, with clear instructions and standard fittings. Also, I looked for a strainer that could be easily disassembled for cleaning without special tools. This way, I can maintain it regularly without hassle.
Pressure Rating
Since water pressure can vary at campgrounds, I checked the maximum pressure rating of the strainer. I made sure it could handle at least 60 PSI, which is typical for RV water systems, so it wouldn’t fail or leak under normal conditions.
Additional Features
Some strainers come with extra features like transparent housings so you can see when they need cleaning, or built-in valves to shut off water flow. I found these features convenient but not essential, so I chose based on my budget.
Price vs. Quality
While shopping, I compared prices but focused more on quality and durability. Investing a bit more upfront saved me from frequent replacements and plumbing issues later on.
Final Thoughts
In line strainers are a small but important part of my RV water system. Taking the time to choose the right one based on material, size, mesh, and ease of maintenance has made a noticeable difference in keeping my water clean and my plumbing hassle-free. I hope my guide helps you find the perfect in line strainer for your RV!
