Picture kneeling by the dump station, sewer hose in hand, wondering if what's draining out the other end is actually clean or if you're just guessing based on how long you've been standing there. You can't see inside a black tank, so most people either over-rinse out of anxiety or pack up early and drive off with residue baking in the heat next to the road. The Camco Rhino Blaster RV tank rinser is built around closing exactly that blind spot.
The whole idea hinges on one small piece of clear plastic: a 45-degree elbow you thread onto your sewer hose before it hits the dump. Water blasts down into the tank through the rinser, and instead of trusting your gut, you watch the flow through that elbow until it actually runs clear instead of brown. That's the moment you know to stop, not a guess. Behind that, a built-in vacuum breaker (a backflow preventer) sits between the garden hose and the tank connection, so if pressure drops or the tank water tries to siphon backward, it breaks the connection before anything contaminated can reach your fresh water hose. The 360-degree swivel fittings and 4-prong bayonet connector mean it twists onto your RV's outlet and your sewer hose without fighting the angle every time, so hooking it up becomes a fifteen-second habit instead of a wrestling match with a garden hose at a dump station.
You're not really buying a hose attachment, you're buying a window and a safety valve in one part: proof the tank is clean, and a guarantee that proving it doesn't put your drinking water at risk. That's the whole trick, and it's why a piece this small changes how you feel about a chore nobody enjoys.
Worth it if
- You already have a gate valve or sewer hose setup this pairs with
- You want to actually see when the tank is running clear instead of guessing
- You're doing manual rinses at dump stations rather than relying on a built-in flush
Skip it if
- You want a permanent, hardwired tank flush system
- You need fittings rated for constant heavy-duty pressure without any care
- You'd rather not add another hose to manage at the dump station
Not for RVers who want a built-in, set-and-forget tank flush system rather than an attachment they connect by hand each time.
If you already run a gate valve or in-line valve setup and just want visual confirmation your tank is actually rinsed, this is a quiet yes. It's not for anyone hoping for a permanent, hardwired flush system built into the RV itself, this is a manual accessory you attach and detach at every dump, and it's only as tough as any small plastic fitting exposed to hose pressure trip after trip.

Is Rhino blaster worth it?
It's worth it if you already have a gate valve setup and want a clear, visual way to confirm the tank is actually rinsed rather than guessing; it's less useful if you wanted a permanent built-in flush system.
How to use camco rhino blaster?
You connect it between your sewer hose and the RV's waste outlet using the bayonet fitting, hook a garden hose to the vacuum breaker inlet, then run water while watching the clear elbow until the flow runs clean.
