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

I though the tank was clean after using this found out that it really was not, if you camp get one

Excellent very easy to use

This is a great tool for the job. It takes the guess work out of dumping. You can see as the tank empties no problem. The hose attachment makes cleaning a lot easier. The second value makes it alot easier to drain the hose and clean it without any spillage.

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.

The idea behind this product is great, but this particular one isnt the highest quality. Ive used it a handful of times now, and noticed that the seal isnt water tight in some spots. The orange connector that locks onto the RV exit valve seems to have a small leak, and much worse, the ball valve for the water/flush hose doesnt have any sort of seal on it. I always have the water connector facing up and my black and grey water never flowing through it enough to have anything come out, but when I connect up my hose and and back flush into the tanks, I can turn that ball valve off, and water will still continue flowing into the tanks through it. I had an extra ball valve so I connect that to my hose before connecting the hose to this product, but without that, black water could potentially flow back into my hose and even up into the water supply at the dump station. Maybe I just got a bad one that didnt get the seals checked properly, and now Im past the time to be able to return it, so I guess Im out of luck. Bottom line: Pros: Love the idea, convenient to be able to back flush to rinse and clear the black water tank, easy to use. Cons: Cheap material, all plastic, seals dont seem to seal the water in, and you may need to purchase an extra ball valve.

Position of release lever is awkward even after rotating the attachment to the drain. The hose hookup is also awkward.

My dump valve isn’t closing all the way and I used this valve to stop the leaking. I leave the primary valve open and close this one so I can keep the tank level up to dissolve waste. I should replace the dump valve but it is a major operation just to get to it.

Sooo, I am a new camper owner with some lessons learned causing me to acquire this device, though you should have regardless. This design allows for swiveling at different points on the neck which comes in handy bc there are times you have to make adjustments depending on which way your hose is going to point. I made the mistake of emptying the black tank completely then using again without filling w/some water to line bottom nor did I use enough water while flushing, therefore some blockage created not draining properly. Upon installing and back flushing several times it freed things up not to mention it assist in cleaning the grey tanks which does not have a back flush feature like my black tank does. Note: I made the mistake by forgetting to open the valve on the tank while having the valve closed on the blaster causing pressure build up and blaster to separate exploding sh#@ all over me! I was able to force the connector back on to the elbow. Currently Im living in the camper full time at my house bc Im remodeling, so I want to leave the hose extended to my septic, the blaster allows me to close its valve instead of always having to disconnect the hose each time. I just empty my tanks, shut rv valves, then blaster valve to keep smells and animals out. This is a very sturdy helpful product, love it.

This is a must have item. Works wonderfully

I was surprised at how well this works. It cleaned gunk out of my tank I didnt even know I had. Quality of build is good and looks sturdy. I had to rotate the valve assembly, but thats not a problem, its designed in a modular fashion to be rotated in whatever orientation you need. It even made my tank sensors work properly again. Tank sensors are notorious for inaccurate readings due to gunk on the sensors. After multiple flushes the sensors in both the black and grey tanks are working again! From now on I will always have one of these in any camper I own. Im a full timer so Ill be using this weekly. I now have a stink and gunk free poo tank, happy camper again. Highly recommended, get one.
