If you use the wrong kind of antifreeze, it can be dangerous, as it seems like it should and might be. Antifreeze made specifically for RVs is harmless and safe to use, keeping in mind that it will wind up in freshwater tanks used for drinking and washing. However, because it is hazardous, automotive antifreeze should only be used in cars and kept out of the reach of children and dogs. If you intend to winterize your RV soon, you probably have concerns about whether RV antifreeze is genuinely safe for septic systems.
As long as you use the right product and make sure to use it properly, RV antifreeze won’t hurt your septic system. System damage might result from using the incorrect antifreeze or using too much. RV antifreeze can winterize both your RV and your home’s septic system when used properly.
It’s crucial to understand the distinction between RV and car antifreeze as well as how to winterize your septic system. This article will examine it as well as any potential substitutes for RV antifreeze.
Is RV Antifreeze Safe for Septic Systems?
RV antifreeze is safe to use in both your RV and septic system at home. Since RV antifreeze is harmless, you can add it to your RV’s water systems without being concerned that it will contaminate the water you use to wash and drink. It is a secure solution for your home’s septic system due to its harmless qualities.
The water in your tanks will not freeze until it is colder since RV antifreeze lowers the freezing point of the water, so even if the water reaches 32 degrees Fahrenheit, it won’t. This will assist in preventing it from freezing in your tanks and pipes, which may result in numerous problems and damage throughout the winter.
Basically, you pour RV antifreeze down your drains and into your toilet after adding it to your RV’s water system. Additionally, make sure you’ve used enough antifreeze so that it’s flowing from your faucets and filling the tank in your toilet. This will prevent the water system in your RV from freezing in the winter. If you intend to leave for the winter or if the property is a seasonal one, RV antifreeze can also be helpful in winterizing your home’s septic system.
What kind of antifreeze can you put in septic systems?
Antifreeze for RVs is not hazardous. Propylene glycol is the main ingredient. Antifreeze made of propylene glycol is often pink-colored and safe to use in septic systems. Ethylene glycol, the main component of automotive antifreeze, cannot be used in septic systems. The component of vehicle antifreeze called ethylene glycol is extremely toxic. Never leave it outside or in an area where animals can access it. Additionally, it harms a septic system. It may destroy the beneficial microorganisms in your septic tank. Additionally, it may lead to an overgrowth of the drain field’s biomass.
Propylene glycol is typically used to make RV antifreeze. It is safe for the environment, non-hazardous, and toxic-free. It can be eaten in little amounts and is secure enough to be used in your RV’s plumbing system.
Other than antifreeze, propylene glycol is utilized in a variety of products. Various foods, hand sanitizers, and even fake tears contain it. Propylene glycol was probably present in any juice you’ve ever consumed in a grocery store bottle intended to be shelf-stable. Using RV antifreeze in your septic tank is also risk-free and won’t result in any issues. A few litres per year won’t affect your septic system’s components and will allow the beneficial bacteria to continue existing and performing their duties.
