Have you ever wondered if Costco Toilet Paper RV Safe is?

Recreational vehicle (RV) vacations are taking the world by storm. RVs give you the opportunity to see beautiful sights and enjoy unplugging from society without needing to leave all of the luxuries of home behind.

They are budget-friendly vacations, and they are incredibly family-friendly.

If you are planning an RV vacation, buying in bulk is a great way to save money. Costco is a popular store for buying bulk products. Their Kirkland brand products are a great bargain, without sacrificing quality.

RV toilets have special requirements, and you need to make sure to use toilet paper that will break down easier, if you want to avoid any problems.

Is Costco Toilet Paper RV Safe? Yes, Costco toilet paper will break down safely for an RV’s toilet, therefore it is safe to use in an RV. However, you should always use toilet paper sparingly to avoid plugging the system with larger clumps of toilet paper.

RV Waste Systems

RVs have waste water systems that include both black water and grey water tanks. Black water includes human waste and grey water comes from sinks and showers. Any water from your toilet will flush into the black water system.

Because your waste water will flush into that black water tank, if you flush things that will not easily break down (trash, plastic, feminine hygiene products, or even the wrong toilet paper), your tank will clog and you will have a huge mess to clean up.

There are bacteria in the black water tank that helps break down the waste, including toilet paper. For this reason, be careful not to flush chemicals, like bleach that may kill that bacteria and slow down the breakdown process.

What is RV Toilet Paper?

Many brands of toilet paper make special toilet paper just for RVs. Other packages of toilet tissue will specify that they are safe to use in RVs.

These have been designed to easily break down and avoid clogging the water system. If a few sheets will easily dissolve in water, chances are that toilet paper is safe to use in an RV.
