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

Looks and sounds great...the flush valve feature only provides way to reverse fill your black or gray tank which would be a whole lot better if it didnt take so long...I prefer my wand with a high pressure rotating head that you put into the toilet from above attached to a hose as it blasts the inside of your black tank cleaning stuck things from interior...

Highly recommend! My RV tank was clogged and wouldnt empty. I tried the chemical stuff to dissolve the clog but no luck. Ordered this product to filled the pipes from below, water pushed the clog back into the tank, then drained. Problem solved! The built-in gate valve is absolutely necessary for doing this. Also works great for intended purpose of just cleaning sludge out of tank and pipes. Dont expect it blast high pressure water into your tank, high pressure only works until the first bend in your pipes, but filling from the bottom still works better and faster than from the top. Lastly, the clear tube is great for determining when your tank is empty, flushing clear water, or still has solids in it.

At $45, I think I overpaid. But it works great

Does allow flushing and backfilling on the black and grey tanks, but the ball valve failed the first time I used it. I was able to use it correctly after adding another ball valve in line, but being that this is for sewage it wasn’t confidence inspiring.

Works well & well made great product

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.

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.

When you drain your tanks, there is always residual liquid in the outlet pipe. With this, close the gate valve and NEVER get unexpected drips in the compartment.

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

I highly recommend this product whether you have a new or older model camper. even though my camper came with a factory in-line tank rinse feature. It doesnt thoroughly rinse everything, especially if the bottom of your tanks have solid dried wast from over time that cant be simply flushed out. The rhino blaster makes it simple and efficient for anyone to use. Easy directions, all that good stuff.
