Why an Air Admittance Valve is Necessary for My RV
As an RV enthusiast, I’ve learned that managing air pressure in the plumbing system is crucial for a smooth and efficient experience on the road. One of the best upgrades I made to my RV was installing an Air Admittance Valve (AAV). This little device has made a significant difference in how my plumbing operates, especially when I’m parked in spots without a traditional sewer hookup.
Before adding the AAV, I often encountered slow drainage and even occasional gurgling sounds from my sinks and shower. It was frustrating, to say the least! The AAV allows air to enter the plumbing system when needed, preventing the formation of a vacuum that can hinder drainage. Now, I can enjoy a comfortable shower or wash my dishes without worrying about water backing up. It’s reassuring to know that my RV’s plumbing is functioning optimally, no matter where I am.
Additionally, the AAV is compact and easy to install, which is a huge plus in the confined spaces of an RV. It doesn’t require extensive modifications to my existing plumbing, making it a practical solution for enhancing my RV experience. Overall, I feel more confident and relaxed knowing that my plumbing system is equipped with an
My Buying Guide on ‘Air Admittance Valve For RV’
When I first started my RV journey, I quickly realized how important proper ventilation is for maintaining a comfortable and functional living space. One of the critical components I discovered during my research was the air admittance valve (AAV). In this guide, I’ll share my insights and experiences to help you choose the right air admittance valve for your RV.
Understanding Air Admittance Valves
Before diving into the buying process, I want to explain what an air admittance valve is. An AAV is a one-way valve that allows air to enter the plumbing system while preventing sewer gases from escaping. This is especially beneficial in RVs where space is limited, and traditional venting can be a challenge.
Why I Decided to Get an AAV
When I noticed unpleasant odors and pressure issues in my RV’s plumbing, I realized something had to change. After some research, I found that installing an air admittance valve could help resolve these issues without the need for extensive modifications to my plumbing system.
Key Features to Consider
As I embarked on my search for the perfect AAV, I made sure to consider the following features:
1. Material Quality
I learned that AAVs come in various materials such as PVC, ABS, and metal. I opted for a durable PVC model because it offers great resistance to corrosion and is lightweight—perfect for my RV.
2. Size and Compatibility
It was crucial for me to choose the right size AAV that would fit my RV’s plumbing system. I measured the existing pipes and checked the specifications of the AAV to ensure compatibility.
3. Installation Process
I didn’t want to deal with complicated installations, so I looked for an AAV that promised easy DIY installation. Many models come with clear instructions, which made my life easier.
4. Ventilation Capacity
I considered how much ventilation I would need based on my RV’s layout. A higher ventilation capacity means better performance, so I made sure to read reviews and compare different options.
5. Brand Reputation
I sought recommendations from fellow RV enthusiasts and checked online reviews. I found that brands with a solid reputation for quality and customer service were more likely to deliver a reliable product.
My Top Recommendations
After extensive research and personal experience, I narrowed down my choices. Here are my top recommendations for air admittance valves suitable for RVs:
- Oatey 39050 – This valve has been a reliable choice for me, offering good airflow and easy installation.
- Sioux Chief 883-2 – I found this model to be extremely durable and effective in preventing backflow.
- Fernco AAV – Known for its flexibility and compatibility with various pipe sizes, this valve has served me well.
Installation Tips
When I installed my AAV, I followed these steps to ensure a successful setup:
- Turn Off Water Supply – Always start by shutting off the water supply to avoid any mess.
- Cut the Pipe – Use a pipe cutter to create a clean cut where you’ll install the AAV.
- Clean the Edges – I made sure to smooth out any rough edges to ensure a snug fit.
- Apply Primer and Cement – If using PVC, I applied primer and cement as per the instructions to secure the valve in place.
- Test for Leaks – After installation, I turned the water back on and checked for any leaks.
Maintenance and Care
To keep my AAV functioning optimally, I make it a habit to check it periodically. I look for any signs of wear and tear or obstructions. Cleaning it occasionally has proven beneficial in maintaining airflow.
Choosing the right air admittance valve for my RV was a game-changer. It not only resolved my plumbing issues but also enhanced my overall RV experience. I hope my buying guide helps you find the perfect AAV for your needs. Happy RVing!
