Enjoy Trips To The Campground With Factory RV's 21-gallon Blackwater Tank

If you're looking for a low-profile blackwater tank with ample storage capacity, you'll want to invest in Factory RV's 21-gallon Blackwater Tank. One of the perks of this tank is that it's designed for RVs where clearance is critical, but it still provides 21 gallons of blackwater storage. Put this tank to good use in tight spaces like undercarriage applications, slide-outs, or custom builds. For long-term durability and reliability, this blackwater tank is constructed using a rotational molding process for a seamless, one-piece construction with uniform ⅛" thick walls. The high-density polyethylene material resists cracking, UV exposure, and chemical corrosion, so you can rest assured that it will withstand the rigors of mobile use. Sold as a blank tank, you can enjoy customizing the inlet and outlet locations to fit your RV layout, and an optional fittings kit is available for a streamlined installation. But it's not just about durability and reliability; you don't like dealing with clogs and buildups, cleaning, or maintaining the blackwater tank. It's only a matter of time before you have to deal with that. So rest assured that our blackwater tank utilizes a low-adhesion interior for a non-stick surface that will prevent buildup, reduce odor retention, and simplify cleaning.
