58 Litre Underfloor Waste Water Tank Kit – Mercedes Sprinter RWD (2006–Present)

This 58-litre underfloor waste water tank kit is purpose-designed for the Mercedes Sprinter RWD (2006–present). It mounts neatly along the driver’s-side outer sill—behind the exhaust and ahead of the rear axle—a proven installation location widely used in professional campervan and motorhome conversions.

Manufactured from high-strength, corrosion-resistant polyethylene, the tank features a discreet matt-black finish with excellent resistance to salt spray, road debris, algae growth and long-term moisture exposure.

A threaded top-access point allows the installation of sensors or internal accessories, while also enabling easy routine cleaning and maintenance.

Locating Instructions – Mercedes Sprinter RWD

Mounts lengthways along the driver’s-side outer sill

 Installed behind the exhaust silencer and ahead of the rear axle

Use the supplied mounting straps to secure the tank to the sill/rail

Ensure adequate clearance from:

 RWD exhaust routing

Heat shields

Handbrake cable

Brake & fuel lines

Because the RWD Sprinter has a deeper sill cavity than the FWD or 4x4 models, the tank fits cleanly without reducing ground clearance.

Important Information

Optional water level senders are available, including models compatible with Victron Energy and SRNE. (Here)

The tank may contain minor traces of water due to leak-testing.

Clean thoroughly before first use.

Intended for grey/waste water only.
