As a avid RV traveler, I have come to learn the importance of having a water check valve in my RV’s plumbing system. This small but crucial component plays a vital role in ensuring that my water supply remains clean and safe to use.

First and foremost, the main purpose of a water check valve is to prevent any backflow of contaminated water into the fresh water system. Without this valve, there is a risk that dirty or contaminated water from the grey or black tanks can seep back into the clean water tank. This not only affects the quality of the water but also poses health hazards for anyone using it.

Moreover, having a check valve also helps to maintain proper pressure in the plumbing system. It acts as a one-way gate, allowing water to flow into the RV’s pipes but preventing it from flowing back out. This ensures that there is always enough pressure for normal use and avoids any potential damage to the pipes due to excessive pressure.

In my personal experience, I have encountered situations where I forgot to close off my grey tank valve before filling up my fresh tank. If it wasn’t for the check valve, I could have ended up with dirty water in my fresh tank and had to go through a tedious process of draining and cleaning it out.

My Buying Guide on ‘RV Water Check Valve’

As an avid RV traveler, I have learned the importance of having a reliable water system in my vehicle. One crucial component of this system is the RV water check valve. This small but essential valve plays a significant role in preventing backflow and maintaining consistent water pressure. In this buying guide, I will share my personal experience and provide you with the necessary information to help you choose the right RV water check valve for your needs.

Understanding RV Water Check Valves

Before diving into the buying process, it’s essential to understand what an RV water check valve is and how it works. A water check valve is a one-way valve that allows water to flow in one direction while preventing it from flowing back in the opposite direction. In an RV, these valves are typically located between the freshwater holding tank and the onboard plumbing system.

Types of RV Water Check Valves

There are two main types of RV water check valves: spring-loaded and gravity-activated. Spring-loaded valves use a spring mechanism to keep the valve closed until there is enough pressure to open it. On the other hand, gravity-activated valves rely on gravity to keep them closed until there is enough pressure from below to open them.

Factors to Consider

When looking for an RV water check valve, there are several factors you should consider:

1. Material:

The material used in making a water check valve can determine its durability and longevity. The most common materials used are plastic, brass, and stainless steel. Plastic valves are lightweight and affordable but may not be as durable as metal ones. Brass valves are more robust but can be prone to corrosion over time. Stainless steel valves are highly durable and corrosion-resistant but come at a higher cost.

2. Size:

It’s crucial to ensure that you get the right size of water check valve for your specific RV model. Measure the diameter of your existing valve or consult your vehicle’s manual before making a purchase.

3. Compatibility:

Not all water check valves are compatible with all types of plumbing systems or holding tanks. Double-check that the one you choose is suitable for your setup before buying.

4. Flow Rate:

Consider how much flow rate is needed for your daily usage when choosing an RV water check valve. A higher flow rate means better pressure, but it may also lead to more significant water consumption.

Tips for Maintenance

To ensure that your new RV water check valve lasts as long as possible, here are some maintenance tips:

  • Clean or replace your filter regularly.
  • Routinely inspect for any wear or tear.
  • If using a brass or stainless steel valve, flush out any sediment buildup periodically.
  • Check for any leaks around the connection points.

In Conclusion

When shopping for an RV water check valve, consider its material, size, compatibility, and flow rate carefully to find one that meets your needs and budget. Don’t forget about maintenance as well! With proper care and maintenance, your chosen valve should keep your onboard water system functioning smoothly on all your future adventures!
