How to Choose the Best RV Toilet Chemicals for Solid Waste?

RV black tank treatment

An RV owner knows how important it is to have a reliable toilet. Keeping your RV toilet clean and odorless can be tough. Various products exist that claim to solve this problem, but deciding which is right for you can be challenging. You should consider the following factors when choosing RV toilet chemicals:

Type of RV Toilet

The most common types of RV toilets are gravity toilets and cassette toilets. Gravity toilets rely on gravity to flush waste away, while cassette toilets use a small holding tank that must be emptied periodically.

Depending on your toilet type, you may need different chemicals. For example, cassette toilets require RV holding tank deodorizers to prevent odors, while gravity toilets may not.

Size of Holding Tank

The size of your tank will directly impact the type and amount of chemicals you need to use. For example, if you have a small tank, you may only need to use a small amount of chemical to achieve the desired results.

You may need to use more chemicals if you have a large tank to break down all of the waste effectively. The type of waste you will be disposing of in your tank should also be considered. You will probably need to use a different chemical to dispose of human waste than animal waste.

No Harsh Chemicals

The most important factor is choosing the right toilet chemicals. Not all products are created equal. Some can damage your plumbing or leave behind toxic residue. These products will break down waste without harming your RV toilet bowl or causing long-term damage to your plumbing.

Be sure to read the labels carefully before making your purchase. Some products may be advertised as “no harmful chemicals” but still contain ingredients that can harm your septic system.

Number of Treatments

Septic tanks waste digester for toilet tissue

The number of tank treatments needed when using RV toilet chemicals depends on several factors, including the amount of waste to be treated, the type of waste, and the temperature.

It is recommended to start with two treatments and increase as needed. This will help to ensure that all the waste is broken down and that there is no material build-up in the tank. It is also important to read the chemical instructions before use and follow all safety precautions.

Suitable for Modern RVs

Some RV toilet chemicals are not compatible with all types of toilets. If you have a modern RV, you may need to use a different type of chemical than someone with an older model. For example, some chemicals may not be compatible with holding tanks with sensors.

These sensors are designed to measure the level of waste in the tank and can be damaged by certain chemicals. If you’re also using formaldehyde-based products in your RV, read the labels carefully to ensure the two products are compatible.

Eliminates and Prevents odors

There are a few key things to look for when determining which RV toilet chemicals will be most effective in breaking down waste and eliminating odors. A powerful enzyme formula will help break down waste quickly and thoroughly. Over time, this will prevent odors from building up.

A good RV toilet chemical should also contain bacteria cultures. These bacteria will consume waste and help to prevent odors from developing in the first place.

Environmental Friendliness

A chemical’s long-term impact should be considered when considering environmental friendliness. For example, some RV toilet chemicals contain bleach or other harmful chemicals that can harm the environment.

Other RV toilet chemicals may use enzymes or other natural ingredients that are more biodegradable and therefore less harmful to the environment.

Safe for All Tanks

When determining if a particular chemical is safe for all tanks, the best place to start is by reading the label. The label should list all the ingredients in the product and any precautions that need to be taken.

If you have any questions about a particular product, it is always best to err on the side of caution and consult with a qualified septic professional before making your purchase.

Prevents Clogs and Success Rate

Consider the success rate and the rating for preventing clogs when choosing which chemical to use. The success rate is the percentage of times the chemical successfully breaks down waste and cleans tank walls. Look for independent testing results or customer reviews to determine the success rate.

The RV toilet chemicals with a high success rate and a high prevent clogs rating are generally more effective at breaking down waste and preventing clogs. The cost of the chemical and the instructions for use must also be considered.

Easy to Use

Some chemicals require that you add a certain amount of water to a tank before adding the chemical, while others come in pre-measured packets that you simply drop into the tank. Some come in liquid form and can be added directly to the tank.

In terms of ease of use, pre-measured packets are generally the easiest to use. Liquids are also easy to use, but you’ll need to be careful to add the correct amount of water to the tank before adding the liquid chemical.

How to Use the RV Holding Tank Treatment?

RV black water tank odor elimination

If you’re like most people, you probably don’t think about your RV’s holding tank until it’s time to empty it. And even then, knowing how to go about the process is not always easy. This can be especially true if you’ve never dealt with a black water tank before.

You can follow some simple steps to make the process as easy and stress-free as possible. Here’s a quick guide on how to use an RV holding tank treatment:

1. Add Water to the Tank: The first thing you’ll need to do is add water to the tank. This can be done by attaching a hose to the water spigot at your campsite and running it into the tank. Alternatively, you can fill up a bucket of water and pour it into the tank.

2. Add the RV Holding Tank Treatment: Once the tank is full of water, it’s time to apply the RV holding tank treatment. Most tank treatments are packaged in pre measured packets that you simply drop into the tank. Others come in liquid form and require you to add a certain quantity of water before adding the chemical.

3. Allow the Treatment to Work: Once the treatment has been added to the tank, it’s essential to allow it to work its magic. This means not using the RV for at least six hours. This will give the chemicals time to break down the waste in the tank.

4. Empty the Tank: When the treatment is finalized, it’s time to empty the tank. A hose can be attached to your RV’s dump valve and run it into a sewer connection at your campsite. If there isn’t a sewer connection available, you can empty the tank into an approved dump station.

5. Repeat as Necessary: It’s essential to treat your RV’s holding tank regularly, even if you’re not using it frequently. This will help prevent odors and ensure the tank is functioning correctly.

How to Get Rid of Toilet Paper in an RV Tank?

Camper holding tank liquid treatments

While it’s essential to use toilet paper when camping, it’s also important to know how to get rid of it properly. This is because toilet paper can clog your RV’s holding tank if it’s not disposed of correctly. There are two common ways you can get rid of toilet paper in an RV tank:

1. Use a Treatment: One of the easiest ways to eliminate RV toilet paper is to use an RV holding tank treatment that contains enzymes. These enzymes break down the toilet paper and prevent it from clogging the tank.

2. Use a Boiling Water Method: If you don’t have an RV  holding tank treatment with enzymes, you can use a boiling water method to break down the toilet paper. Simply bring a pot of water to a boil and pour it into the tank. Allow the water to sit for an hour before draining it out.

How to Clear a Clogged Camper Toilet?

Septic tank treatment

If everything were just right, your camper toilet would never get clogged. But sometimes things happen, and toilets get blocked. If this happens to you, don’t panic. You can follow a few simple steps to clear a clogged camper toilet.

1. Shut Off the Water Supply: First, you’ll need to shut off the water supply to your RV. This will prevent more water from entering the tank and worsen the clog. Plus, it’ll give you time to work on fixing the issue without having to worry about making a mess.

2. Add a Clearing Agent: Once the water supply is shut off, you can add a clearing agent to the toilet. This will help break down the clog and make removing it easier. In most cases, you can simply pour a cup of toilet cleaning solutions into the toilet and let it sit for an hour.

3. Use a Plunger: After the clearing agent has had time to work, it’s time to use a plunger. Plunging the toilet will help to dislodge the clog and get things moving again.

4. Use a Drain Snake: If the plunger doesn’t do the trick, you may need to use a drain snake. This is a long, flexible piece of metal that you insert into the toilet to break up the clog.

5. Call a Professional: If you’ve tried all of the above methods and still can’t get the toilet unclogged, it’s time to call a professional. A plumber can clear the clog and get your toilet working quickly.

Frequently Asked Questions

There are a few questions that are commonly asked about RV holding tanks. Here are some of the most one:

1. Can you mix RV antifreeze with toilet chemicals?

RV antifreeze is designed to prevent water lines from freezing in cold weather. Toilet chemicals are designed to break down waste and prevent clogs. While both products contain some similar chemicals, they are not designed to be used together.

Mixing RV antifreeze with toilet chemicals can potentially damage your RV’s plumbing and wastewater systems. If you need to use antifreeze while your RV is in use, be sure to add it only to the black and gray tanks (never add it to the freshwater tank while in use).

2. When do you put chemicals in the RV toilet?

When do you put chemicals in the RV toilet

These chemicals usually come in the form of powders or liquids, which need to be added to the toilet after emptying. This is because the chemicals need moisture to work effectively, and if they are added to a dry toilet, they can cause odors by creating a buildup of gunk.

In general, you should add chemicals to the toilet when refilling the tank with freshwater. This way, you can ensure that the chemicals will be properly activated and start working immediately.

3. How often should I empty my holding tank?

Generally speaking, empty RV holding tanks every three to five days or when they reach two-thirds to three-quarters full. Dumping frequently helps to reduce the possibility of waste buildup, which can clog sensors, cause odors, or lead to misreading tank levels. In addition, it’s essential to inspect your tanks for cracks or leaks regularly.

4. How do you break down poop in an RV tank?

Rv toilet chemicals break down human waste and prevent it from building up in the RV tank. The most common chemical is formaldehyde, which breaks down organic material and prevents the growth of bacteria.

These chemicals can be added to the RV tank through a special valve or poured directly into the toilet. To make sure that the chemicals are properly diluted, empty the tank and add chemicals with each batch of water.

5. How do you keep an RV toilet from smelling?

Taking care of an RV toilet isn’t difficult, but it does require some upkeep to prevent odors. The first step is to make sure the tank always has enough water. This will help keep things flowing smoothly and prevent clogs.

You should also add water with each flush and use black tank chemicals to help break down waste. Scouring and cleaning the tank periodically will also help keep odors under control. Be sure to clean the toilet and the flapper valve regularly as well.

Conclusion

For a comfortable RV experience, you need to maintain your RV toilet properly. Keeping one of those chemicals from our list of the best RV toilet chemicals for breaking down waste will make your life much easier.

They all offer different features that can make your life easier, including odor control and extended RV holding tank life. You’ll be glad you invested in keeping your RV toilet clean and functional, regardless of which one you choose.
