RV Holding Tank Frequently Asked Questions

RV Holding Tank FAQs

The three types of RV holding tanks are black water tanks, gray water tanks and fresh water tanks. Black water tanks contain sewage and waste from the toilet. Gray water tanks contain wastewater from the sinks and showers. Fresh water tanks contain clean water for drinking, cooking and washing.

RV rotomolded tanks have several advantages over other types of tanks, such as metal or fiberglass tanks. Some of these advantages are:

  • • They are durable and impact-resistant, which means they can withstand rough road conditions and harsh weather.
  • • They are leak-free and seamless, which means they prevent water contamination and odor problems.
  • • They are lightweight and easy to install, which means they reduce fuel consumption and labor costs.
  • • They are customizable and versatile, which means they can fit any shape, size, or capacity requirement.
  • • They are FDA-approved and BPA-free, which means they are safe for storing drinking water and human waste.
