55 Gallon Water Preserver Concentrate 5 Year Emergency Disaster Preparedness, Survival Kits, Emergency Water Storage, Earthquake, Hurricane, Safety

First time user. I hope this works. Dropper works fine. Took a minute to figure out how much to use per gallon.

5 stars for easy & simple instructions to follow! It helped simplify the water storage process for me and I appreciate having a product that will help my water to have a 5 year shelf life. It was nice to read through reviews of people who have tried their water after the 5 years and that it still tasted and smelled great and fresh. I look forward to tasting it in 5 years.

Great for emergency water storage.

I bought this to add to our water storage. We like to keep water on hand for a power outage.

I live in a state that gets its share of earthquakes. I have stored water and other supplies for when "the Big One" hits. I have been storing water using Water Preserver Concentrate for many years. I store the water in seven-gallon plastic containers. About every five years or so I empty out the containers, and I refill them with fresh water mixed with a carefully-measured amount of Water Preserver Concentrate. I then label each container with a large tag, showing the date it was filled. So last month the five-year period was up on some of these containers. It was time to pour out the old water and refill. But I was curious: Was this five-year-old water still safe to drink? Well, I don't have access to a scientific laboratory, so I tested the old water by drinking some of it. I figured, if the Water Preserver Concentrate was doing its job as claimed, this old water should still be safe to drink. And it turns out, it was indeed safe. I drank about six or eight ounces of the five-year-old water, and I suffered no ill effects. (I did this on a day when I knew I would be home all day, just in case I had to run to the bathroom or something.) I expected that perhaps the water would have a plastic taste (from being stored in a plastic container for five years) or perhaps a bleach-like taste. But it just tasted like regular water is supposed to taste. So I am pleased to say that this stuff did work as claimed. However, let me add a little more info that may be relevant. First off, when it is time to fill these plastic containers with water, I wash my hands and try to ensure that there is no chance of germs entering the containers. Also, I tightly seal each container, and I store them on the floor of the closet, covered up with a thick blanket to keep away sunlight. So I am really anal about doing what I can to make sure the water will stay drinkable.

We are using this for our water storage in 55 gallon drums. I have no doubt that it will keep the water fresh. It’s worth it for piece of mind.

I used this product in a new blue 55 gallon water barrel and then I covered the barrel with a cardboard box to keep it clean and so no light could penetrate the plastic barrel. Anyway, my water has sat in a corner of the garage (out of sight, out of mind) for 7 years. I drained the old water this week. It was perfectly clear and clean and the taste was OK, though it was a little flat.Some folks have complained about the price, but when you spread $15 over five years , I think that is pretty cheap for a product that is made for water preservation with no muss or fuss.

It has been 5 years since I last applied this chemical to my two 55 gal water storage barrels. I am confident it performs as described.
