RV Holding Tank Treatment (Top 5 Recommended on Amazon)

Most of us don’t like to talk about this topic but doing regular maintenance on our RV’s septic system is important. As none of us would want to use stinky porta-potties, as well as dirty common bathroom cubicles, managing our own RV holding tank is very helpful and convenient for all of us.

Given the benefits an RV holding tank can provide us, it is necessary to take proper care of it to prevent its deterioration. In this article, we will discuss the best RV holding tank treatment and the factors to consider before you buy one. We have the top 5 picks, as well as some tips.

Factors to Consider Before Choosing The Best RV Holding Tank Treatment

While there are numerous choices for the best RV holding tank treatment, you have to ensure that the factors mentioned below are considered to make choosing the best one a lot easier.

  • Travel time: Your RV’s toilet system might require extra consideration if you are planning on traveling for a long period of time, especially if you do not have the time or chance to discharge the holding tank. It should also be noted that an RV that has a portable toilet should always have an extra tank for bigger capacity.
  • Composition: The one you should buy must not contain harmful chemicals, however effective they may be, such as formaldehyde. These are not environmentally friendly and can cause irritation to chemically sensitive people.
  • Material: If you care about the environment, you should consider choosing an organic and biodegradable product. In addition, choosing a non-toxic holding tank treatment is guaranteed to deliver the same result as those that contain harmful chemicals.
  • Type: It is important that you consider this factor first. As you will see below, there are various types to choose from, and it will save you a lot of time if you know what type you are looking for initially.
  • Compatibility: While there are many types and products to choose from, consider buying the one that you will be able to use for both black and gray tanks. This will save you a lot of money as you only need one instead of buying two separate treatments.
  • Ease of use: The RV holding tank treatment you should consider buying must be easy and convenient to use. Some products cause spillage when measuring. This is already considered a hassle because extra cleanup will be required. So as a helpful tip, go for the product that will not create a mess when using.
  • Features: Before you evaluate the price of the product, review the features carefully first. This will give you enlightenment on what features you will most benefit from.
  • Price: This is also considered a very important determining factor when choosing the best RV holding tank treatment. Product features, pros, and cons should be carefully reviewed to be able to come up with the price you will be willing to pay for the product.
  • User reviews and ratings: First-hand experiences are vital because they detail how well the product has worked out for the actual buyers. User ratings also give you a summary of these reviews.
