Rated 5 out of 5 by from This is an RV Must If you have an RV, this is a must-have. The Flush King is nothing that you really want. However, it is something you didn't know you would need. The Flush King attaches while emptying your black or gray tank. I was amazed, and a bit disgusted, with the amount of material that came out of the black tank the first time I flushed with this. Needless to say, I'll be using this each time we empty the tanks to ensure there's no leftover "residue".

Rated 5 out of 5 by from Sensors working in the tank again! No stink! Used this baby and flushed our black tank six times before there was no TP chunks coming out. Totally amazed at how this worked. Now we just do it once after we dump and keeps it clean. Solved the odor issue after the trailer sits for a couple weeks unused in the heat, too. Awesome!

Rated 5 out of 5 by from Works that's all I can say about that We found our black tank fouled with the Pooh. So how to get it open and some folks said backflush and dang it worked so well the water was clear on the third backflush and our sensors read empty for the first time since new....keeping it on board for future needs...

Rated 5 out of 5 by from The Flush King is “Royally” Good! I’ve used a Flush King for years. It’s the best tank flush system I’ve found. Far superior to most of the built-in systems that just don’t have enough pressure to do the job. Simple to use and set up.

Rated 1 out of 5 by from Cant seem to receive the needed item. Still haven't received this item. After placing the order, was told it was backordered, then The original estimated delivery date has come and gone. No way to know if it is a good item.

Rated 5 out of 5 by from The Flush King backflusher It makes back flushing your tanks so easy. Attaches easily to your drain valve. Using it helps to ensure tanks are clean avoiding buildup and expensive service/repairs

Rated 5 out of 5 by from Works well Bought this after a recommendation from another RVer who saw me struggling with a wand in a campground. Worked just as he described.
