Why an Accumulator Tank for My RV is Necessary
As an avid RV enthusiast, I’ve come to appreciate the importance of an accumulator tank in my setup. Initially, I didn’t fully understand its value, but after a few trips with inconsistent water pressure and constant pump cycling, I realized how crucial this component is for a smoother experience. An accumulator tank acts as a buffer, storing water and helping to maintain consistent pressure in my RV’s plumbing system. This means no more sudden bursts of high pressure or drops that can lead to annoying water hammering sounds.
One of the most significant benefits I’ve experienced is the reduction in wear and tear on my water pump. With the accumulator tank in place, my pump doesn’t have to work as hard or cycle on and off frequently. This not only prolongs the life of my pump but also saves energy, which is particularly important when I’m boondocking or relying on my RV’s battery. I’ve noticed that my water system runs much more efficiently, allowing me to enjoy my time outdoors without worrying about the mechanics of my RV.
Furthermore, having an accumulator tank ensures that I always have a steady flow of water, whether I’m washing dishes, taking a shower, or filling up my water jug
My Buying Guide on Accumulator Tank For RV
When I first started looking for an accumulator tank for my RV, I found myself overwhelmed by the options available. After some research and personal experience, I’ve put together this guide to help you navigate your choices and make an informed decision. Here’s what I learned along the way.
What is an Accumulator Tank?
An accumulator tank is a storage device that helps to maintain water pressure and supply in your RV’s plumbing system. It acts as a buffer between the water pump and the fixtures, reducing the need for the pump to cycle on and off frequently. I found that having an accumulator tank not only smooths out the water flow but also extends the lifespan of the pump.
Benefits of Using an Accumulator Tank
- Consistent Water Pressure: One of the most noticeable improvements I experienced was the consistent water pressure. No more sudden drops when someone flushes a toilet or turns on the faucet!
- Reduced Pump Cycling: My water pump no longer runs as often, which means less wear and tear. This was a significant factor in my decision to install an accumulator tank.
- Noise Reduction: I noticed a decrease in the noise from the water pump. The accumulator tank absorbs some of the vibrations and sounds, making for a quieter RV experience.
Types of Accumulator Tanks
- Bladder Accumulator Tanks: These tanks feature a rubber bladder that separates the air and water. I found these to be the most common and effective for RVs.
- Diaphragm Accumulator Tanks: These have a flexible diaphragm that separates the water from the air. While they are less common in RVs, they still serve a similar purpose.
- Size Considerations: When choosing the size, I recommend considering your RV’s water system and typical water usage. A tank that is too small won’t provide the benefits I enjoyed, while one that is excessively large can take up unnecessary space.
Factors to Consider When Buying
- Capacity: Think about how much water you typically use. I chose a tank with a capacity that matched my needs, ensuring I didn’t have to refill too often.
- Pressure Rating: Ensure the tank can handle the water pressure of your system. I learned the hard way that a tank with too low a pressure rating can fail under pressure.
- Material: Look for tanks made from durable materials that can withstand the elements. I opted for a corrosion-resistant option, which has proven to be worth it during my travels.
- Installation: Some tanks are easier to install than others. I appreciated options that came with clear instructions and all necessary fittings.
My Top Recommendations
- Shurflo Accumulator Tank: This tank has a great reputation for reliability and performance. I found it easy to install and it has been a game-changer for my water pressure.
- Camco Water Tank: This one is budget-friendly and performs well for smaller RVs. It’s compact, which worked perfectly in my limited space.
- Valterra Accumulator Tank: Known for its durability, this tank has served me well on multiple trips. It’s built to last and has excellent pressure retention.
Installation Tips
Installing an accumulator tank is relatively straightforward, but here are a few tips based on my experience:
- Choose the Right Location: I made sure to place mine close to the water pump for maximum efficiency.
- Check for Leaks: After installation, I ran the water system and checked all connections for leaks.
- Adjust Air Pressure: Don’t forget to pre-charge the tank with the correct air pressure (usually around 7-10 psi) before connecting it to the water system.
Final Thoughts
Investing in an accumulator tank for my RV was one of the best decisions I made for enhancing my water system. It not only improved water pressure but also made my trips more enjoyable. I hope my experiences and insights help you find the perfect accumulator tank for your RV! Happy travels!
