This item is fantastic. After the first week with our new travel trailer
we found none of the three holding tank level indicators registered
correctly after dumping. The dual flush pro arrived from Amazon.com a
couple days before they said it would. After several flushes in the black
tank and one each for the grey tanks every thing was back to normal. I
couldn't be more satisfied! 5 stars

It arrived in a timely manner. It was the product, I wanted, and works well. I recommend this product to all RV people who need a new waste disposal unit. If i need anything else for my RV I will go to this company first which is found on Amazon.com. Amazon.com is the place I look for things I need first. 4 stars

Was absolutely essential to clear a clog in my BW tank. Did a great job. Is made of heavy duty plastic and quality valve. On/off, spray adjuster knob leaks by but I didn't care. It is not meant for permanent mounting anyway. Highly recommended as an essential tool for your RV. 4 stars

This product is very easy to use by your self or with someone inside the RV watching the tank level indicator. I filled and flushed my black water tank 3 times to get the tank clean. My level indicator light now works properly as a result. This product costs less than the version sold at Camping World, so it's a win-win. 5 stars

I purchased this as a backup for my almost 4 year old Flush King. The price was right so I thought I'd give it a try.

I use a h2owatch meter to monitor my incoming gallonage. In 4 minutes the Camco put in 6 gallons while the Flush King added 30 in the same time period.

For those with small holding tanks and in no hurry, this might be the answer. I however have three 40 gallon tanks to flush and must do so multiple times.

In my opinion, this is nothing more than a poorly designed knock-off.
