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

Worked as advertised, very satisfied with it

Watch to make sure completely empty

The one I got came broken, the valve that controls the water from the hose came broken as in it wont turn on/off, its constantly on and slightly leaks. However, my black tank had a blockage at the drain valve and I was able to use this product to successfully and quickly back flush my black tank. Only reason for not 5 stars is because it came broken, otherwise a perfect product. Hopefully my next one will be flawless ☺️

The water valve leaks just the fresh water going in but it seems not not have a good seal.

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.

excellent product made cleaning the black & grey tanks so much easier.

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...

I ordered this to help unclog the black tank on my travel trailer. Originally I expected it to take a week to get to me but it only took two days, which is super impressive. Even more impressive that it worked so well at getting the black tank unclogged. Im only sorry I didnt purchase this sooner.

This model has a much larger incoming water path than the other brands Ive tried. I use this along with a water meter to backfill/clean the tanks in our 5th wheel. With the other brands, it took much too long to fill the tanks, due to a very small hole in the incoming water valve. This one allows a lot more flow and fills the tanks faster, making the job easy.

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.
