This works great on your rv thank

Smells the best

Read about this product online. I had a stubborn black tank draining issue and decided to give it a shot. Problem solved!It’s the ONLY thing I use for both my campers now.

So I had to live in my trailer 50% in Palm Springs away from my home in Arizona for work for 2 1\2 years. I was new to this RV lifestyle so it was a learning process. Over time my trailer developed an odd smell resulting in my wife refusing to use the trailer. In fact I was concerned that i had developed a mold problem or some undetectable propane leak. I contacted a local RV service center in Phoenix and explained my issue and he immediately told me that over the past 2 years that I had not treated my grey tank and that the smell was bacteria growth. The technician specifically told me to buy PurePower and flush the tank twice. Well long story short my trailer now smells amazing and the wife wants to go camping again. I will alway buy this product and use in both grey and black tanks. This product is superior and does what it advertised. Note I bought the green one which was fantastic. However the newer blue version is supposed to be even better. If you're on the fence just buy it!

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, I'm 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.

This stuff works like a charm.

...and this is the best I have used to maintain our tanks. It works! It is easy to use. It is economical.We spend the winters in warm climates and have a large motor home/ large holding tanks.Pure Power maintains odors between emptying. And a little does a lot! Just 2 ounces per 40 gallons. We do empty our tanks once a week so this 64 ounces goes a long way. My routine is to measure the 2 ounces and empty right into the toilet. Then fill the toilet with water and using a brush, scrub the toilet and flush. So now the toilet is clean and the chemicals properly administered to the black tank. I only use this in the "gray tank" when it is closed.Pure Power does not contain formaldehyde. A very important feature for me.

Works well

Es muy efectivo

This is the best product out there. Works in less then 12 hours.

I like the lines on the bottle to guide you as to how much to pour. Seems to work fine, not crazy about the scent but it's not offensive.

This stuff is the best product I have used in the 10 years of camping inhale done. I let it soak in my tanks with clean water for a week and all my sensors work properly again. They have ent been right in 3 years. This stuff is great.

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