Happy Campers RV Black Tank Cleaner, Sensor & Holding Tank Cleaner

I have used once following instructions, it cleaned .

Great

This stuff is awesome 1 scoop and your tanks smell so clean you feel like you could eat off of them highly recommend this product

Followed the directions to a T, made a 3 hour trip down several winding/bumpy roads. It worked to eliminate the majority of buildup as far as I could see. My tank was the cleanest I’ve ever seen it as viewed from the open commode and when we drained and rinsed tank, there was no odor (which is an improvement.) But, my sensor still doesn’t work. I guess I’m going to have to buy a wand and flush it out. Overall I’m happy with the product but I wish there was more than 1 treatment for the price. It would be nice to have a second treatment to repeat the process and see if it works to clean my sensor. It’s too expensive to purchase a second time without a guarantee that it will fix the issue.

Love this brand and feel safe using it

I had great hopes for this product after reading all the glowing reviews and the assurance of a money back guarantee printed on the back of the container. Unfortunately, I was underwhelmed. I have been trying hard to get the sensors to read properly for weeks. I have had some success with various combinations of water softeners Calgon and Boraxo paired with detergents Dawn and Tide. Progress has been slow. I usually can see some thin, black flakes up to the size of a quarter through my clear plastic fittings when draining the grey tank after treatments..I even see some from the black tank. I back flush the black tank from the grey tank and flush the black tank from the top and from the built in side rinsing connection. I tried two cans of Extreme Cleaner hoping it would be more effective than what I had been using. I followed the directions to the letter, drove all day then dumped at the next opportunity. I did see a little more debris from the grey tank flush out than I usually saw after dumping the detergent and softener solutions I had been using but not a significant amount. The grey tank sensors still indicate at least 2/3 full on an empty tank while the black tank bounced back and forth between Empty and 1/3 full. This product may work eventually but appears to have the potential of just dumping money down the drain. I have no idea what the previous owner of my coach did or didn't do to the tanks so I may just have a tough case on my hands.

Works well: This stuff is AMAZING! I have a used 2012 travel trailer and the black tank stank SO bad, despite using an enzymatic treatment several times. Tried Happy Camper cleaner and took a three hour drive. After dumping, not only is the bad smell gone, but the toilet smells GOOD when flushing! This stuff works miracles! I’m sold!

Use as instructed and did nothing to clean black tank or the sensors. I know our tank is empty, but yet it wants to show full on the sensors.

It did exactly what the company said it would do.

Se nota que limpia algo, lástima que sea sólo 1 uso y que sea tan caro.

Follow the directions. I left this product in for two days. Black water tank in boat. Did a great job.

hope it works

Use it to get the trailer tanks clean
