The Doobie Brothers may have had a hit with the rock classic Black Water but when it comes to the black water in your RV’s holding tank, there isn’t much to sing about - unless you have a high-quality, efficient tank in place. This 40 Gallon RV Black Water Holding Tank offered by RecPro hits just the right note. Manufactured by industry leader Elkhart Plastics, this tank is strong, durable, and it is a great choice when it is time to replace the black water holding tank in your RV or travel trailer. It is also a great choice for any application that requires a holding tank.

This tank measures 56” x 30” and is 6” in height. The outlet valve included is 3”. This tank is a blank, which means there are no fittings on it (other than the outlet). We do this so that you don’t have to work around any existing fittings or try to figure out how to fit it in with your existing plumbing structure. To make the installation process go smoothly, a fittings kit is available that can help you customize your tank to your RV’s exact needs. When you install this 40 Gallon RV Black Water Holding Tank from RecPro, you’ll be “On the Road Again” without worry. No returns or refunds are available on special order items.

Don’t keep such an important system in the hands of a mediocre tank. Upgrade to this EPI tank from RecPro and roll down the road with peace of mind. Have any questions? Contact us online or call our friendly Customer Care team today!
