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

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.

Im so glad I got this while my RV was still new, otherwise I would have just assumed that the black tank indicators werent fully reliable. Using this I now realize how much matter is left after draining the tank - mostly toilet paper even though we use the RV stuff that is supposed to dissolve. I empty the tank, then close the gate and spray, partially filling the black tank with water. I repeat until the indicator light shows the tank is empty - which can be 3 times, but it doesnt take long at all and is really easy to use. I got a black hose so that there is no mistaking it for the potable water hose. One of the best RV accessory purchases Ive made, absolutely essential.

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.

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

I purchased this to unclog a grey tank. I have been trying for a week to unclog my grey tank without success. I attached the rhino camco, attached the hose and turned the hose on, walla cleared in seconds. The hose water attached perfectly and you can change the direction of water spray to either grey or black tank. Cleans both out without an issue. Id recommend this to any RVer as a weekly part of cleaning.

A must have if you have an RV/trailer

Works perfect! Cleans tank easily and very well

The Camco Rhino Blaster Sewer Cleanout is fabulous. Since using it, I can easily tell when my tank is clean. My sensors have started working again since my purchase also because I know my tank is clean.

Watch to make sure completely empty

I bought a used rv that didnt have a washout spigot. I used this every time Ive dumped all winter long and the tanks no longer have ANY odor. I still used tank tabs in the black and odor control liquid in the grey, but this allows a clear washout every time.
