The Importance of a 40 Gallon RV Water Tank

As an avid RV traveler, I can confidently say that a 40 gallon water tank is an essential component for any successful trip. Not only does it provide a sufficient amount of water for daily needs, but it also offers peace of mind and convenience.

First and foremost, having a 40 gallon water tank ensures that you have enough water for all your basic needs while on the road. This includes drinking, cooking, cleaning, and showering. With a smaller tank, you may find yourself constantly refilling and worrying about running out of water. However, with a 40 gallon tank, you can comfortably use water without constantly monitoring your supply.

Moreover, many campsites and RV parks have limited or no access to running water. In such situations, having a large capacity tank becomes even more crucial. It allows you to stay at these locations for longer periods without worrying about running out of water. This not only saves you time and effort but also adds to the overall enjoyment of your trip.

Having a 40 gallon water tank also provides convenience when boondocking or dry camping. These are situations where you’re not connected to any external sources of electricity or water. In such cases, your

My Buying Guide on ’40 Gal Rv Water Tank’

As a frequent traveler and avid RV enthusiast, I have come to realize the importance of having a reliable water supply while on the road. After many trials and errors, I have found that a 40 gallon RV water tank is the perfect size for my needs. In this buying guide, I will share my personal experience and knowledge to help you choose the best 40 gallon RV water tank for your own adventures.

Why do you need a 40 gal RV water tank?

A 40 gallon RV water tank is an essential component of any recreational vehicle. It provides a convenient and accessible source of clean water for drinking, cooking, showering, and flushing toilets. With a larger capacity than smaller tanks, it allows for longer periods of use before needing to refill.

Factors to consider before buying

Before purchasing a 40 gallon RV water tank, there are several factors that you should consider:

1. Material

The material of the tank plays a crucial role in its durability and longevity. The most common materials used for RV water tanks are plastic (polyethylene) and metal (aluminum or stainless steel). While plastic tanks are lightweight and affordable, they are prone to cracking or warping under extreme temperatures. On the other hand, metal tanks are more durable but can be heavier and more expensive.

2. Shape and size

Most 40 gallon RV water tanks come in either rectangular or cylindrical shapes. Rectangular tanks are ideal for larger vehicles with ample storage space, while cylindrical tanks are more suitable for smaller RVs with limited storage capacity.

3. Installation

Consider how easy or difficult it will be to install the tank in your RV. Some tanks come with pre-drilled holes for easy installation, while others may require additional fittings or modifications.

4. Weight when full

Keep in mind the weight of the tank when it is full of water as it can significantly affect your vehicle’s overall weight and handling. Make sure your RV has enough load-bearing capacity to handle the additional weight.

Additional features to look out for

Apart from these basic factors, there are some additional features that you may want to look out for when purchasing a 40 gallon RV water tank:

– BPA-free material: This ensures that your drinking water stays safe from harmful chemicals.
– UV protection: If your tank will be exposed to sunlight, UV protection will prevent algae growth.
– Fittings included: Some tanks come with all necessary fittings included in the package.
– Warranty: Look for tanks with at least a one-year warranty to ensure quality and reliability.

Maintenance tips

To ensure your 40 gallon RV water tank lasts long and functions properly, here are some maintenance tips:

– Regularly clean out any debris or sediment from inside the tank.
– Avoid using harsh chemicals when cleaning as it can damage the material.
– Inspect the fittings regularly for any leaks or damages.
– Drain and sanitize the tank at least once a year.

In conclusion

A 40 gallon RV water tank is an essential investment for any traveler who wants convenience and independence on their trips. By considering all these factors and features before making your purchase, you can find the perfect water tank that meets your needs and fits seamlessly into your RV setup. Happy travels!
