Rated 5 out of 5 by from excellent product We purchased this product 1 year ago. Our black tank was reading full after we dumped. We tried the wand, and we would also just fill tank while holding toilet valve open. It would not get the tank clean. The Flush King is great. The 1st time we used it ,we needed to flush 6 or 7 times, but we finally got clean water and the tank sensors work 100%. No more wondering if the tank is clean and it is very easy to use. My wife just lets me know when she see's the water level in the toilet and I drain the tank. After years of blaming sensors and really not knowing the condition of our black tank, the guessing is behind us. GREAT PRODUCT.

Rated 4 out of 5 by from Is your holding tank clean? I have a toy hauler that is two years old . I have owned it for just over a year. the gray water has always drained slow . When I saw the Flush King on sale I decided to give it a try. I can't say if it helped the gray water but when I did the black water the crud just kept coming. It took four times flushing before the large crud stopped flowing, then three more times before the water appeared clear as it flowed thru the transparent elbow.I have used a wand ,in the past, for the black water.With the large quantity of crud that came out using the Flush King my guess is I wasn't using the wand correctly or it doesn't do the job. I feel the Flush King was worth the price.

Rated 5 out of 5 by from Great Addition The Flush King is money well spent. I purchased it after I started noticing my tanks were not draining completely, at least according to my gauges inside. After using the Flush King I have had no problems getting the tanks flushed out completely. It usually takes four or five times of backfilling and flushing.... especially on the black tank... but the extra time it takes waiting and draining over and over a few times is worth keeping the system clean and the inside of my RV odorless. I highly recommend this item to anyone who doesn't want to spend the extra money to get a permanent tank rinser installed... this gadget does the job and at much less the cost.

Rated 5 out of 5 by from saved us money We are new to RVing and did not have good experiences with dumping our black waste. We watched a dvd on RVing and this was recommended so we bought it. It made a world of difference for us. It makes dumping so much easier cause you can actually see when the line is clean. And for us it pointed out that the valves were reversed on our grey and black water and that is why we were having so much trouble when we dumped our black tank. It was actually the gray tank we dumped. If we hadn't been able to see what was coming out of the line we might not have ever figured that out till our tank was ruined.

Rated 5 out of 5 by from Rocket Science At first I was turning on the water with the big valves closed and water squirted everywhere, oops. So be sure to have at least one big valve open first. Also to be safe I am using a special grey colored hose just for sewer use but I feel I need an additional backflow preventer at the faucet end too, I will be looking for this, I wish FlushKing offered it. Otherwise It's pretty quick and efficient. I feel it locks in place securely. Caution when my tank was partially frozen the waste water came up my sink and spilled all over my carpet within 90 seconds. One drawback of not being inside using a wand.

Rated 5 out of 5 by from The Flush King is AWESOME!!! The Flush King made my day. My monitor for the black water tank was stuck on the second level. I tried the wand trick but to no avail. I was not looking forward to meshing with the black water tank. Until I read some information about the Flush King. The write ups and the reviews I read about the Flush King were all positive.So I decided to make a purchase. It is a purchase I will never regret. For as long as I own an RV, I will always have a Flush King.It is so simply to use,I could not beleive it. I think I'm going to take my wand and throw it in the trash.Ha!! It's money well spent and no hassle.

Rated 5 out of 5 by from Wow..The best thing since sliced cheese. The other reviews on this site convinced me to buy the Flush King. Before I bought it I was using one of those wands to clean the black water tank and I was getting a terrible smell everytime we flushed. I hooked it up and started to clean the tank and WOW you would not believe the stuff it gets out of that tank that you didn't know was there. I flushed my tank 6 or 7 times before I finally stopped seeing TP going through the pipe. Now it has been a week since I cleaned the tank and the temps here have been around 100 degrees every day. I went out to the trailer last night and opened the toilet and there is NO SMELL! I was thrilled to say the least. You will not regret buying this thing!

Rated 5 out of 5 by from This is a Great Product I bought this product after a friend at a campsite showed me his. What an invention!!! I dumped my tank like I normally would and then rinsed the hose out by dumping the gray water tank. I borrowed his and filled up my tank with water and you wouldn't believe how much extra stuff came out!! So I bought one. First trip out with it after I had totally cleaned my tank (or so I thougtht) I tried to clean and flush the dark water tank and I filled it and dumped it about 20 times and each time more and more extra stuff came out until the water was very clean. A must purchase, in my opinion.!!!!!

My handle pulls straight forward, not up/down. Will this King still work?

The gate valve can rotate around the translucent elbow. <a href=https://youtu.be/oi8HUknP46Y>Here</a> is a product demonstration for the Flush King.
