Even though the plumbing and sewer system in your recreational vehicle is one of its most important components, few RV owners take the time to inspect the system to ensure it is in top working condition. But if they suffer a leak or system rupture in the middle of a camping trip, they'll wish they had paid more attention to the sewer system before leaving home. If you believe your RVs sewer system is starting to show its age, it's time to replace the black water tank with the RecPro 48 Gallon RV Holding Tank. Our EPI 4470 tank will give you excellent performance now and well into the future, as it features Elkhart Plastics' rotational molding process that gives the tank strength and durability. Elkhart is well known in the industry as one of the top manufacturers of plastic materials, and its black water tanks are no exception. This holding tank is built to the same manufacturing tolerances as your OEM tank at 83" x 20.25" x 16.5", so it will fit in the same spot. This means it will seamlessly mesh into the RV's sewer system, greatly reducing the chances of a leak. At 48 gallons of capacity, you can spend more time at the campsite relaxing and less time traveling to the dump station to empty the tank. At RecPro, we stock the best aftermarket parts for recreational vehicles, giving you the ability to keep your RV on the road and in top working condition.
