Camco 39085 Rhino Blaster Pro Holding Tank Rinser w/Gate Valve

The perfect solution for draining your RV black tank, when the drain pipe gets clogged. Also good for back-flushing (please follow instructions. All connections are of swivel type, easy to connect and user friendly. Would recommend this product to anyone who owns an RV.

This product was very easy to use! It was great to be able to rinse out the tank all in one step

Let me begin by saying Im sort of OCD when it comes to keeping my things clean during and after I used them. I came across this tool in an RV YouTube video that talked about the black water tank. During my educational research to make sure I am doing and cleaning everything properaly, I decided this is a must. I used it for the first time a couple of weeks ago, before that I was either dumping 5 gallons at a time to rinse out the black water tank, or dragging a hosing inside to fill it up to get additional flushes. It takes about 3 to 4 flushes to see clean/clear water consistently, and with this set up it seemed to improve the process with the water back filing the tanks. The fresh water valve and clear elbow in one place also helps. My suggestion for peace of mind, also get a quality digital water flow meter that can be reset between fills, this way if you have a 30 gallon tank, you know when to turn it off without having someone stand watch or you running back and forth to check on it. Using time a gauge isnt a good idea since the locations will have different pressures and flow rates, the digital meter will be the most accurate in this case. If you want your tanks clean (I even back flush the gray tank) for storage then this is a must. If youre new to RVing also suggest watching videos on how to maintain the tanks while not is use. Tons of great information out there. I use a Simple Green Lemon and Calgon mix in the black tank and Pinsolve and Calgon in the gray tank, both with 5 gallons of fresh water to slosh around and keep it clean. Hope this helps.

I hooked up product per instructions. After a couple of minutes it had the black water draining out and I even washed it out a few times after getting the blockage clear. For once a product worked as advertised. It’s worth the money.

Works perfect! Cleans tank easily and very well

Always a difficult job to clean out our black water tank after dumping. We often use a hose down the toilet which can be messy. I have tried this just once and its great. Easy to use. We feel it cleans the tank thoroughly after dumping. We carry a spare short non potable water hose, just in case the dump station does not have a hose with a threaded end (Which the usual case). So far so good.

I’ve been looking for something to be able to flush out both black and gray tanks of my motor home. This tool connects between the tank discharge valve and sewer hose and has a water hose connection so water can fill up either tank after emptying back up the discharge connection. The tank can drained by opening the gate valve below the hose connection. This process can be done several times to flush out the tanks. It works great and simple to hook up.

This worked great the first 2 times I used it. On the 3rd time the ball valve for the freshwater side blew off and poo water started spraying out of it. I ended up finding the valve and the Orrington holding the valve in place was split. The screw was also missing. This caused that valve to fail and blow out of water connection. Amazon did send a label for a refund. I plan to replace it now that I know what I need to check on the valves.
