You’ve ripped up your substrate. You’re ready to upgrade that pesky factory-installed tank that has been leaking and causing you nothing but problems. You peel back that last piece of bonded plywood and…what the…

Before you lies the most complicated and complex tank construction you’ve ever seen. In your own imagination you couldn’t have conjured something so convoluted to hold your RV’s black water. It looks like a glitch from Minecraft. How in the world are you ever going to find a tank that will even come close to fitting this monstrosity you see sitting in your recreational vehicle’s well? Guess what…we’ve got your back. We’re RecPro and we think of these things before you even encounter them. That’s how we’ve become the industries one-stop-shop for all things related to RV tanks!

The 0294H from EPI is a unique tank style to say the least. An odd construction, it’s a testament to engineers trying to cram as much storage space as is humanly possible into a cramped area. No matter how difficult it may make it for the consumer to replace down the road. It’s ok. The folks at EPI have made just the tank to fit your complicated well and added a ton of quality along the way. This tank, though oddly shaped it may be, holds to the strict quality standards at EPI. It, like all tanks that leave their facility, is pressure tested and thoroughly inspected so that when you go to install it, you can set it and forget it (except you’re not making rotisserie chickens!)

Because this is a unique construction, the plumbing to the area will be complicated. We have a full line of accessories and fittings kits to help you during your installation. Let RecPro help take this nightmarish process and turn it into a dream by giving you the right parts and the right fitting tank today!
