Camco Dual Flush Pro Camper/RV Holding Tank Rinser - Features 3-Inch Gate Valve & Reverse Flush Valve - Empties & Flushes RV Black Water Tanks and RV Sewer Hose (39062)

When i got my camper last year, the tank level lights were apparently covered in, well...let's just say they weren't working correctly. Camped close to home a couple of times & the water source at the pump out site was broken, so I didn't get to try this out until recently when we took the camper to a different spot for almost a week. About midway through, I packed up & went to the clean out & got to use this for the first time. Works amazingly. After a good flush out my level lights were working correctly. Used it again before we left.I thought maybe I needed new sensors. Nope, just needed to actually clean my holding tanks.I recommend this to anyone with holding tanks, whatever vehicle they're in.

This thing is a lifesaver. I had a clogged tank out of nowhere. I spent 3 days different methods and tank additives trying to sort it out. Finally I ordered this thing. Hooked it up to the outside attach the garden hose and the stinky slinky, and follow the instructions. I turn the garden hose on spraying into the tank for about 30 seconds. My tank was pretty full at that point. I turned around and let it drain and a lot came out. I did that process again and let it fill up more and a lot more came out, My tank drained. After that I went ahead and cleaned the tank for good measure. My 30 gallon tank took a couple of minutes to fill from the garden hose. I let it fill all the way and drain it. Now I use this thing a couple times a year just to clean the tank out. This is rescued multiple neighbors and travelers through my park. Every once in a while I'll see someone with the look of desperation and frustration trying to drain their tank and I already know what they need. This thing does the trick every time. And every time someone uses it they immediately go on Amazon and order one for themselves. If you don't need this yet you're going to. Buy it now it's the only thing you'll ever need.

This works great for the outside hose connection! Easy to install and works decent at back filling the tanks!

Just what I ordered

Works well for the purpose intended.

This allows you to give your black and gray wastewater tanks a good flushing out and help get the residues, sludge, and solids freed up and washed away.Someone really thought through the process when they designed some of the features,This product seems to be well built with quality materials. The clear polycarbonate adapter lets you see your progress as you flush the tanks and you can see when they are clean.The universal 3-inch gate valve with a standard bayonet style fastener fits most sewer hose outletsThe built in gate valve keeps the water flowing up into the tanks, and then opened to release the rinse water effectively flushing more debris out. I have used this a few times now and I am surprised at the stuff that still comes out of my tanks even when they seem to be clean.This is great for trailers without a built-in tank sprayerYou want to put a lot of water into the tank when flushing and I would also recommend you purchase a water flow meter to put on the hose you use for this so you can keep track of how much you put in.

I love this product, it's amazing I know when my tank is clean but I think it is made of the worlds worst plastic. The hose bib for the water supply breaks off super easy. These are not cheap and I have probably bought 5 or 6 of them now. I am very carful with them but just the weight of the water in the hose will break off the water connection and then you have a huge mess! Will I buy another one? Probably. Will it break again in record time? Probably.... ugh

I just purchased my first travel trailer. It is a used trailer and I was very apprehensive about dealing with the septic. I purchased one of these Dual Flush units along with a tank wand and a few other items to be as prepared as I could. I found this tank rinser to be extremely useful and it made the whole process much easier to deal with. For my review I'll list the features this unit provides and how I used it on my first trip. I ended up having a clogged up system since the previous owner failed to flush properly after their last use. This unit saved me from what could have been a major issue.1. Visibility - My septic line does not have a clear section at the outlet. This unit adds that and it's very convenient to be able to see the flow you are getting when you open your drain valves. The first indication of a clog is poor flow or a sudden drop in flow when you open your valves. This is what happened for me. After opening the valves flow began then stopped abruptly and my black tank levels never dropped below 2/3 full with valves wide open. I tried flushing with a wand through the toilet first but no luck.2. Tank Flush - This unit lets you flush the tank from the drain outlet. I wouldn't see this as a replacement to using a wand through the toilet or built in tank rinser (if you have one) but it does have one "HUGE" benefit, you can use back pressure to clear a clog. My system was clogged and the wand wasn't clearing it. I closed the outlet valve on this unit, hooked up my water hose and set the valve to "flush tank". Water immediately filled the drain and began to back flushed the tank. Any clog was pushed back into the tank. After a few minutes I shut off the water and opened the drain valve. The flow was much improved but eventually slowed down again. I repeated this a few times and after 3 flushes the tank emptied normally. I then went back and cleaned the tank with a wand and we were done. If I hadn't had this unit I'm not sure what I would have done but it probably would have involved opening the sewer line or trying to snake the clog out from inside. Yuck!!3. Hose Flush - When your ready to disconnect you want to flush your septic hose. Normally you dump you grey water after emptying and closing your black tank to rinse the hose. Additionally you would probably disconnect the hose and spray it out with your water hose. With this unit you simply close your black/grey water drain valves, switch the direction valve to "flush hose" and turn on the water. This flushes your hose with fresh water without disconnecting it. Much better option than disconnecting if you asked me. Once rinsed you your satisfaction you can disconnect and plug your hose.In closing, this item is a "Must Have" for me. I would not use any other method than this type of flush valve plus a wand for flushing my tanks and hoses.
