What does RV holding tank treatment do?

RV holding tank treatments help eliminate odors by liquefying solid waste. Depending on the product, it may contain enzymes, which physically break down the particles, or strong chemicals such as formaldehyde. Not only that but it also prevents clogs in the tank by breaking down RV toilet paper.

How often should you use toilet treatment in an RV?

Ideally, you want to use a digester treatment after each time you empty the holding tanks and you want to do that every three to five days. Alternatively, you can empty the tank when it's two-thirds full or when the sensor lights come on.

How long does it take a digester treatment to work?

The exact time differs depending on the product but generally speaking, you should notice an effect within a few minutes. For the best results, hold the flush pedal down (for as long as you reasonably can) after using the product.

Can you use black tank treatment in a grey tank?

The black water tank holds water from the toilet, including human waste and toilet paper, while the grey water tank holds water from sink and shower drains. Generally speaking, digester treatments are only meant to be used with the former. However, some products are compatible with both. When in doubt, check the product description on the packaging.

Can I treat my RV holding tank with vinegar?

White vinegar can be used to sanitize and deodorize the black water tank. You can even mix it with baking soda for additional cleaning power. Keep in mind, however, that it won't be able to kill all the germs that's living in the tank. What's worse, is that it may also kill off the 'good bacteria'. Given that, it's best to use commercial digester treatments instead.

Are holding tank digester treatments septic safe?

Most RV holding tank digester treatments are safe for septic systems (it should say whether or not they are on the packaging).

Are RV holding tank digester treatments necessary?

Digester treatments are highly recommended if you want to minimize smells. If anything, they're the only product that's capable of physically breaking down waste. In doing so, they'll also prevent clogs and other issues, especially if used regularly.

How do I keep my RV black tank from clogging?

Digester treatments will prevent clogs by liquefying organic waste and toilet paper. Also, be sure to use a RV-specific toilet paper; they're made to break down in the holding tank. Regular toilet paper will build up and cause a clog.
