- How it Works: Air admittance valves are operated by gravity; When water and waste move down a drain line, it creates negative air pressure in the pipe; This negative pressure lifts the sealing washer and lets air in, which allows the waste to drain away freely; When the negative pressure ceases, the sealing washer falls back in place; Earlier versions of this device were spring operated; Such units are still available but are unreliable and don't meet code in most areas
- Easy to Install: The sealing disc of the vent must be at least 6 inches above the top of the trap arm; To ensure that this requirement is met, you can extend the tube using a sliding joint; An angle installation of no more than 15 inches from the vertical direction is acceptable; After determining the placement, you can install the Air Admittance Valve on the PVC drain line

Choosing the Right Air Admittance Valve for Your Mobile Home Kitchen Sink
Mobile homes have unique plumbing setups. Sometimes, standard venting doesn’t work well. That’s where an Air Admittance Valve (AAV) comes in handy for your kitchen sink. An AAV lets air into your drainpipe. This stops gurgling noises and slow draining. It helps your sink work smoothly. This guide will help you pick the best one.
Key Features to Look For
When shopping for an AAV, check these important parts:
- **Flow Rate Capacity:** This tells you how much air the valve can let in. Make sure it matches your sink’s drainage speed. A small capacity valve will fail under heavy use.
- **Valve Type:** Most mobile home sinks use a simple mechanical (spring-loaded) valve. These are reliable.
- **Mounting Style:** Does it fit easily under your sink or connect to the existing vent pipe? Some screw in; others push fit.
- **Ease of Installation:** Since this is for a mobile home, you want something simple to install yourself. Look for models that require minimal tools.
Important Materials for Durability
The material matters for how long your AAV lasts. Moisture and drain chemicals can break down cheap plastic.
Plastic Components
Most AAVs use plastic. Look for high-quality, durable plastics like ABS (Acrylonitrile Butadiene Styrene) or PVC (Polyvinyl Chloride). These plastics resist common household cleaners. Cheaper plastics can crack over time, especially in temperature changes common in mobile homes.
Seals and Gaskets
The rubber seals are crucial. They must seal tightly to keep sewer gases *out* of your kitchen. Look for resilient rubber or silicone gaskets. Poor seals cause bad smells.
Factors That Improve or Reduce Quality
Good AAVs work silently and reliably. Bad ones fail quickly.
Quality Boosters:
- **Brand Reputation:** Established plumbing brands usually offer better testing and warranty.
- **Testing Certifications:** Look for certifications like UPC or IAPMO. These mean the valve passed strict safety tests.
- **Accessibility:** Can you easily reach the valve if you need to check it later?
Quality Reducers:
- **Overly Complex Designs:** Simple designs usually have fewer parts that can break.
- **No Protection:** If the valve lacks a screen or mesh, debris can get inside and jam the mechanism. This is a major quality reducer.
User Experience and Use Cases
An AAV solves a specific problem: poor venting.
When You Need an AAV:
You need one if your sink drains slowly after a big load of dishes. You might also need it if you hear loud glugging or sucking sounds coming from the drain. Mobile homes sometimes have short, complex drain lines that don’t vent well vertically. An AAV provides local venting right where the problem is.
Installation Experience:
A good user experience means installation takes under 30 minutes. You should simply cut into the pipe (if needed) and attach the valve according to clear instructions. If the instructions are confusing, the quality is likely lower.
10 FAQs About Mobile Home Kitchen Sink AAVs
Q: What is the main purpose of an Air Admittance Valve?
A: Its main job is to let fresh air into the drainpipe. This stops a vacuum from forming when water rushes down the drain.
Q: Are AAVs legal everywhere in mobile homes?
A: Most local plumbing codes allow them for repairs or additions where traditional venting is difficult. Always check your specific local mobile home park or county rules first.
Q: How often should I replace my AAV?
A: Most manufacturers suggest checking the valve every two years. If it stops working, replace it immediately. They usually last between five and ten years.
Q: Can I use a standard sink AAV under my mobile home kitchen sink?
A: Yes, if the valve is rated for kitchen sink drainage (which handles grease better). Ensure the flow rate matches your sink size.
Q: What happens if the AAV fails or gets stuck closed?
A: If it sticks closed, the drain will start gurgling and slow down significantly, just like an old, blocked vent pipe.
Q: Does the AAV stop sewer gas smells?
A: Yes, when the valve is closed (which is most of the time), the internal seal blocks sewer gases from coming up into your kitchen.
Q: Do I need special tools to install a mobile home AAV?
A: Usually, you only need a hacksaw to cut the pipe (if needed) and maybe a screwdriver or wrench for tightening fittings. It is generally an easy DIY job.
Q: Will an AAV work if my drain pipe is completely blocked?
A: No. An AAV fixes venting issues, not clogs. If your sink is totally stopped up, you must clear the physical clog first.
Q: Should I buy a plastic or a metal AAV?
A: For mobile home kitchens, durable plastic (like ABS) is usually preferred. It is lighter, cheaper, and resists corrosion well.
Q: How do I know if my AAV needs cleaning?
A: If you notice slow draining or gurgling noises returning, the valve might be dirty or stuck. Some models allow you to unscrew the cap for inspection and cleaning.
