Benefits of RV Holding Tank Treatment

  • Mask odors. Riding around with a horrid smell coming from the bathroom is not a fun way to spend a trip. Holding tank deodorizers can cover up and get rid of bad smells so you don’t have to leave the windows open.
  • Prevent major clogs. Over time, the septic tank will fill up with unmentionables. Since there is no sewer line for the waste to travel through, the chemicals dissolve most of what is inside the tank. The best RV waste digester will clean out the largest and toughest blockages.
  • Save money. Dealing with a clogged and oversaturated camper holding tank can lead to a large bill. Using a high-quality compound treatment will ensure you aren’t left cleaning up more than you bargained for.
  • Clean the system. RV holding tank treatments are designed with special enzymes that clean the system as well. Many even clean level gauges, so the system can tell how full the tank is and alert you of any issues. 

Types of RV Holding Tank Treatment

Tablet

Tablets work by dissolving in the toilet water to form tiny particles that run through to the septic tank. These particles flow to and through blocked areas to dissolve or disintegrate waste and any remaining toilet paper over a period of time. Typically, they have to be used on a monthly basis. 

Liquid

The liquid form of RV waste tank cleaner pours into the toilet and flows down into the septic tank. It works faster because it’s able to move more easily through waste and compounds inside the holding tank. However, its basic function is the same as a tablet form; it dissolves and breaks down waste and toilet paper over time.

Top Brands

Camco

Founded in Greensboro, North Carolina, Camco has been around for more than 50 years. The company develops products for ATVs, boats, RVs, and plumbing needs. Any RV owner most likely has a Camco product on board and should consider the Camco Ultra-Concentrate Orange Scent RV Toilet Treatment for their septic tank.

Thetford

The company began in the early 1960s and created the first slide-action valve for RV holding tanks in 1963. Thetford designs products for motorhomes and travel trailers, especially ones focused on the toilet and septic tank. One of its top septic treatment products is the Thetford Aqua-KEM Original-Holding Tank Treatment.

RV Holding Tank Treatment Pricing

  • $10-$20: With RV holding tank treatments, you will mainly pay for the size and type of the container. Within this price range, you’ll find anything around 24 ounces and smaller.
  • $20 and up: This price range will typically contain larger bottles and containers that offer more solution for more applications. Consider buying the treatment in bulk to make sure you’ve got extra just in case you run out when you need it most on the road.

Key Features

Long-Lasting Protection

You shouldn’t have to worry about adding the treatment solution every day or week. The best RV holding tank compound will make sure the black water tank or the grey water tank is free of blockages and odors for at least a month. It’s recommended to apply the solution once every month to make sure the tank is properly cared for.

Bottle Size

While it will not take an entire bottle to treat a holding tank, having multiple bottles or tablets on hand can save time and money in the long run. Since you should apply the treatment every month, knowing you have a few bottles on hand means you don’t have to worry about running out or forgetting to order more.

Additives

Holding tank chemicals work to remove debris, break down waste, and dissolve toilet paper. The ingredients making up the composition may vary from product to product, yet all will increase the output of the treatment. Some even include detergents for added smells. However, they are not a permanent solution to clearing out the holding tank. Eventually, you will have to completely remove everything inside the tank.

Other Considerations

  • Ease of Use: Applying RV septic tank treatment can be a quick or slow process. You can simply pour or drop in the compound within a few seconds or take your time and apply it throughout the day. 
  • Compatibility: Before you add a tablet or liquid to the tank, it’s important to note if the brand is compatible with your specific holding tank. Many are rated to handle tanks up to a certain size, so if you have a large space but a compound that works on smaller tanks, you may need more solution.

Rid-X will ensure no one is able to smell any lingering odors wafting around the RV toilet. With specifically designed enzymes and natural bacteria, this compound is formulated to break apart toilet paper, grease, and other waste inside the toilet and tank that would clog the pipes. It’s even rated to work on marine vehicles, so you can bring it anywhere.

It is simple to apply directly to the toilet and takes only a few seconds. Plus, it only requires a small amount to take effect, so you don’t have to stock up on several bottles. All you have to do is add a bit of water after the product is dropped in to ensure it works properly. One of the major benefits of Rid-X is the included citrus scent that hangs around after the compound mixes inside the toilet.  

One of the side effects of this treatment is the smell of the compound. It is a sour odor that can be a bit overpowering to some and can linger in smaller RVs.

Tips

  • Make sure to clean or dump out the septic tank to get rid of the dissolved contents. This will ensure it continues to function properly.
  • Consult your RV’s owner manual before purchasing any RV holding tank treatment. It will help let you know which types are usable in the septic and how to properly clean it out if there are any issues.
  • Avoid cleaning the toilet bowl or tank with chemical toilet products. They are designed to kill the good bacteria that help unclog the septic tank and keep it odor free.

FAQs

Q: Will an RV treatment product completely clean out the tank?

A: No. Even the most powerful septic tank treatments are not capable of cleaning the entire tank. You will have to either get a professional to clean out the tank or dump it out yourself.

Q: Can I use any type of RV toilet paper with the septic tank treatment?

A: You should stick with toilet paper products that are rated specifically for motorhomes. These will generally be thinner tissues with a lower ply count. They are designed to prevent clogs and buildups in RVs.

Q: How often should I dump out the septic tank?

A: We recommend you dump out and clean the septic tank every four to five days. However, this also depends on the number of people visiting or living in the RV. The more people using the facilities, the more often you will have to empty the system.
