The Doobie Brothers sang about Black Water in the 1970s. Cartoons have been named after black water. The black water you’re trying to contain while you ramble down the road isn’t anything to sing about, though, nor is it worthy of making a cartoon for. It’s a serious subject that most owners don’t want to deal with until they have to. When they have to, it’s generally too late. Well, you don’t have to worry. We’re RecPro and we’re here to help.

One of the products that we take very seriously is the RV tank. Whether it’s gray, potable, or black water, we makes sure we proved the level-best industry parts so that you don’t have to worry. All of our tanks are from top-tier manufacturers. Just like this 30-gallon tank from EPI. Elkhart Plastics Inc. is one of the best in the world at manufacturing tanks. Their stringent manufacturing processes ensure that the tank you get can take the hits that the road dishes out.

This tank is a true blank and a custom piece. Why do we provide true blanks when it comes to tanks? There are as many models of RV as there are stars in the sky (ok, that’s hyperbole but you get what we’re saying.) If we had every model of RV, concession trailer, toy hauler, and pop-up tank available we’d have to have more warehousing than the government. Even then it wouldn’t be enough because most plumbing in RVs isn’t the same. So, we make it so that you, the consumer, have the ability to custom build your tank to fit your needs. We have installation fittings kits, sensors, gauges, and upkeep items at the best prices around. You can get this black water gear for a song!
