Organic RV Holding Tank Treatment - 18 Treatments | Controls Odors, Helps Prevent Clogs, Buildup & Sensor Issues, Black & Gray Tanks, Supports Reliable Dumping

I have tried all the caravan toilet treatements over 40 years. Uk dealer shops are stuffed with competing heavy, bulky liquid products. This is #1 in the USA primarily for their large live in units. I use 1/2 teaspoon of the white powder in the touring caravan WC waste tank. One tub lasts me years. Also this treatement works much better than 'our' smelly liquids in hot weather. I suspect not on (shop) sale in the UK because this would cut profits.

I had heard about 'Happy Campers' when I was visiting some friends in Florida who had their own RV (apparently this stuff is legendary round US Campsites). I myself have a boat with a black waste holding tank, which has a tendency to emit some nasty smells whenever flushing or otherwise agitating the tank. The instructions are precise and following them, you wont go wrong (only niggle is its all in US Gallons, but this is an imported thing), just put one scoop in a toilet filled with water, and flush. My tank is around 250L, so around two large scoops with two full bowls of water should be enough. After using just one treatment, I've already noticed a huge difference - so far absolutely no odours! I'm shocked!! So much better than the Blue stuff that people use. As the package says, it doesn't mask odour, it eliminates odour. We are due a pump-out of the tank in a month, so will update so far as how it dissolves toilet paper and other material.

At last….. drain grey water in public without the nasty odours, cannot believe how this product just simply banishes grey tank stink. Even in very hot temperatures open the valve, no smell, marvellous.

I live in an American RV in the UK. I previously used different options for the black tank. There was always a lingering smell, especially when it got hot in the summer. I was recommended this product by another RV'r, and I must admit it is very good. There is zero smell, and being organic, I can use it in the RV park, which doesn't allow chemicals. Very happy to recommend this. Yes it is expensive but it is shipped from the USA

No smells, easy use, easy store, cheap per shot in our MoHo grey water tank.

We’re currently enjoying life full-time in our RV here in Australia. Even though it’s been pretty hot and our tanks have started to smell💩 a bit because of the heat, a couple of scoops of Happy Camper did the trick — problem solved!

I have been using this product for 15 years. No odours ever and simple to use. I can't say enough about how well to product works

Product as described, effective for RV septic tanks

So far so good, our tank was a little smelly for the first time. Even though we always careful to put the right treatment product into our travel trailer tank. We used one scoop of the "Happy camper toilet treatment" and crossing our fingers....the smell is gone.....Great experience so far, easy to use and the container will last for a long time. Perfect item.

Love! Love! Love! No more smell!!!!!!!!
