Why an Air Admittance Valve for My RV is Necessary
As an RV enthusiast, I quickly learned that maintaining proper ventilation and drainage in my vehicle’s plumbing system is crucial for a hassle-free experience. One of the key components that I discovered to be essential is the Air Admittance Valve (AAV). This seemingly small device plays a significant role in ensuring that my RV’s plumbing operates smoothly, and here’s why I think it’s necessary.
First and foremost, the AAV helps to equalize pressure in my RV’s drainage system. When I use water in my sink or shower, it creates a vacuum that could potentially disrupt the flow of wastewater. Without an AAV, I’ve noticed that my drains could gurgle or even back up, which is definitely not something I want to deal with while camping. The AAV allows air to enter the system, preventing those annoying drainage issues and ensuring that everything flows as it should.
Additionally, having an AAV installed has significantly reduced the odors that sometimes waft up from the plumbing. I’ve experienced the unpleasantness of sewer gases creeping into my living space, and since I added the AAV, that problem has been virtually eliminated. It acts as a one-way valve, allowing air in
My Buying Guide on Air Admittance Valve For RV
When I first started looking for an Air Admittance Valve (AAV) for my RV, I wasn’t exactly sure where to start. After some research and personal experience, I’ve compiled this guide to help anyone else navigating the world of AAVs for recreational vehicles. Here’s what I learned.
Understanding Air Admittance Valves
Before I made a purchase, I needed to understand what an Air Admittance Valve is and why it’s important for my RV. An AAV is a one-way valve that allows air to enter the plumbing system when there’s negative pressure, preventing the traps from being siphoned dry. This is crucial for maintaining proper drainage and preventing sewer gases from entering my living space.
Why You Need an AAV for Your RV
In my experience, having an AAV in my RV has dramatically improved my plumbing system’s efficiency. Without it, I noticed slow drainage and occasional gurgling noises from the sinks. An AAV helps to balance air pressure in the plumbing system, which is essential, especially when the RV is in motion or parked on uneven terrain.
Types of Air Admittance Valves
During my research, I found that there are different types of AAVs available. Here’s a breakdown:
- Plastic AAVs: These are lightweight and resistant to corrosion. They are a great option for RVs because of their durability and ease of installation.
- Metal AAVs: While these are sturdier, I found them to be a bit heavier and potentially prone to rusting over time, especially in humid environments.
- Inline AAVs: These are installed directly in the plumbing line and are ideal for larger RVs or those with more complex plumbing systems.
- Horizontal AAVs: Designed for spaces where vertical installation isn’t possible, these can be a lifesaver in tight spots.
Key Features to Look For
Here are the features I considered essential when buying an AAV for my RV:
- Size: Make sure to choose an AAV that fits your plumbing system. I measured the diameter of my pipes and selected accordingly.
- Pressure Rating: Check the pressure rating of the valve. A higher rating ensures that the valve can handle the variations in pressure that occur in an RV.
- Certification: I always looked for AAVs that are certified to meet plumbing codes. It gave me peace of mind knowing that I was purchasing a reliable product.
- Ease of Installation: Some AAVs come with straightforward installation instructions, which I found incredibly helpful. I preferred those that didn’t require professional help.
Price Range
From my observations, the price of AAVs can vary widely based on brand, material, and features. I found basic plastic AAVs starting around $10, while more advanced models could go upwards of $50. My advice? Set a budget and look for the best value that meets your needs.
Installation Tips
When it was time to install my AAV, I followed a few simple steps:
- Turn Off the Water Supply: Always ensure that your water system is off before starting.
- Cut the Pipe: I measured carefully and used a pipe cutter for a clean cut.
- Install the AAV: Following the manufacturer’s instructions, I attached the AAV securely.
- Test for Leaks: After installation, I turned the water back on and checked for any leaks.
Maintenance and Care
To keep my AAV functioning properly, I made it a point to check it regularly for any signs of wear or damage. I also ensured that it was free from debris and obstructions, which helped prolong its lifespan.
investing in an Air Admittance Valve for my RV has made a significant difference in my plumbing system’s performance. By considering the type, features, and installation tips I’ve shared, I hope you feel more prepared to make a purchase. Happy RVing!
