RV Water Tanks

Plastic-Mart offers a wide range of RV water tanks for sale. Plastic-Mart's RV holding tanks, such as our RV fresh water tanks, RV gray water holding tanks, and RV black water holding tanks, are FDA approved.

We provide standard and custom fittings for our 3 gallon, 10 gallon, and even 100 gallon RV water tanks. Our RV water holding tanks are rotomolded from FDA approved plastic resin, safe for fresh drinking water storage, yet strong enough to be used as septic, greywater, or blackwater tanks if needed.

Plastic-Mart also carries RV water pumps that make it easy to sanitize RV water tanks. We provide equipment like inlets for different types of RVs and campers, whether it be travel trailers, fifth-wheel trailers, pop-up campers, or toy haulers. 

Contact us now to learn more about fittings, sizes and water tank replacements.
