Valterra V22002 Pure Power Waste Digester and Odor Eliminator - 32 oz. Bottle

The PRODUCT, overall, is excellent! I have used it for nearly 20 years, with absolutely no problems. My most recent purchase was with Amazon as a seller, though, and there was something wrong with the bottle that was delivered to me. I did not use it right away, but it did not sit for any longer than any other one I ever purchased. However, Im thinking it must have been from a defective batch, or else exposed to extreme heat or cold, because I might just as well have been pouring water into my black tank. It did not work at all. I highly recommend THE PRODUCT, but watch the seller; after this, if I order it again, I will open each new bottle right away and make sure the bacteria are functional, before the time to return the bottle expires.

Good stuff, have used it for years

Read about this product online. I had a stubborn black tank draining issue and decided to give it a shot. Problem solved!

Just like I’ve been using for 6 years

I have used this product for the last 15 years in my RV waste system. 11 of those years we were full timing and never used another product. We learned about it from another full time RVer, The Road Princess who strongly recommended it. We have never been disappointed

My favorite so far.

Great stuff

pas de très bonne qualité, odeur reviens après 3 jours dutilisation dans une toilette portative avec même une utilisation restreinte

I could smell the box before I opened it. I dont even want to try it. The smell is so bad. If you want a nice scent and not a porta potty smell, do not choose this.

Worked great
