The RhinoBlaster attaches directly to your RV sewer outlet and sends a high-flow blast of water up through the drain pipe and into your black or gray holding tank. It dislodges stubborn waste, flushes odor-causing residue, and keeps tank sensors reading accurately -- all without any internal flush port or special valves inside the coach.
Even after a full drain, holding tanks routinely retain waste deposits, grease, and solid residue along the walls and around the sensors. Left unchecked, that buildup is the root cause of persistent odors, inaccurate level readings, and eventual clogs. The RhinoBlaster solves all three problems in a single step you can do at any dump station with a standard garden hose hookup.
Unlike built-in tank flush systems that require a dedicated plumbing port inside the rig, the RhinoBlaster works externally -- attaching to the sewer outlet you already use to empty the tank. The 45-degree angled nozzle directs water up the center of the pipe and into the tank, maximizing coverage without requiring you to reposition or move the tool mid-rinse.
Directs the water blast up the center of the drain pipe and into the tank, not just at the pipe walls, for a thorough interior rinse every time.
Built-in vacuum breaker prevents contaminated sewer water from back-siphoning into the freshwater supply -- a critical health and compliance safeguard.
Locks quickly and securely onto standard RV 3-inch sewer outlets. Swivel design lets you orient the hose connection without twisting the tool off the pipe.
Made from sturdy, break-resistant polyethylene that handles outdoor use, UV exposure, and the mechanical stress of repeated dump-station attachment cycles.
RV holding tank sensors are notorious for giving false "full" readings caused by waste coating the sensor probes. A proper flush after every emptying cycle keeps those sensors accurate, which means you stop guessing how much capacity you actually have -- critical when boondocking or dry camping away from hookups.
The RhinoBlaster connects at the sewer outlet, so it works on any RV that uses a standard 3-inch sewer drain -- travel trailers, fifth wheels, Class A, B, or C motorhomes. You do not need a factory-installed tank flush port for this tool to work.
Using the RhinoBlaster is a straightforward two-step process you add to the end of your normal dumping routine:
Always rinse the black tank first, then the gray tank. Running the gray water through the sewer hose at the end helps flush any remaining residue from the hose itself before you store it.
