I haven?t actually tried it but it?s in my bug out bag in case the zombie apocalypse happens

Followed directions but was only able to sanitize 44 gallons from one unit.

I bought one of these six years ago for my 10 WaterBricks (35 gallons at 3.5 gallons each). Then after five years, I dutifully bought another and replaced all my water, treating them again. The instructions are needlessly long, but could be helpful to people new to the concept of long-term water storage, advising the type of container to use and why the product is better than household bleach. Though designed for one 55 gallon drum, instructions include 8 drops per gallon, which is useful if you aren't using a drum. Instructions are only in English, but the English is perfect. We've used treated water for road trips and could not detect any flavor at all.

This is a good product and very convenient. The only problem was the bottles had some slight leakage during shipping. This leaking ruined the instructions but it?s ok we got what we needed on website. Note to waterpreserver.com, pack the instructions outside the plastic bag.

this is just bleach, save your money. Product does what it says. Active ingredient is sodium hypochlorite, just bleach.

Thanks

Need this if your intp prepping.

I got this product to keep 55 gallons of water safe to drink over a long term. I haven't purchased the 55 gallon container yet but I will

Very easy to use. Last?s a very long time.

Easy to use, affordable, seems to work

I will let you know more in 5 years. I discs taste test when I filled the emergency bottles and the water tasted just like always

Easier to use than the 2 part system

Hope it works well, I have preserved a number of gallons of H2O for future use.

Won't know how good this product is until; when?

I hope it will work as promised, bleach is cheaper

Husband likes it

Whats to say?
I use it, I think it works, but I have never had to test it.

good buy

like

Great product - very useful and easy!

:)

Whitens whites! Brightens Brights! Because its F$$cking Bleach in a tiny bottle! 5 stars! Best scam ever!

Good product. I have used in the past and will use again.

Preserver NOT purifier.

Handy to have. Easy to use on 55 gal barrel.

Using it now......check back in 2 or more years

VERY NICE

Have 2 55 gal tanks for water and this to keep water safe for long period of time, haven't used yet

Useful for our water earthquake tank

Used this product as instructed but have no idea if it will be drinkable in an emergency in the near future or preserve water without issue for 5 years as advertised.

Gift

It seems good. We won't know for sure until more than 5 years.

It did the job nicely.

I will find out how well it worked , Check on me five years from now.

We have decided to have this on hand just in case. I like to be prepared

Try it you will like it.

Part of the emergency prep kit -- thanks!

ok

Happy with my purchase!

wont know for a while if this product work , but is easy to use and priced well

Got for emergency use....

waiting to use it

The only way to safely store water for long term and be confident of the results

I have heard of bleach methods but the water preserver concentrate seemed more desirable from my perspective.

We used 7 gallon cubes with the according number of drops for purification.

With a little room in the container we have accounted for expansion and are good to go!

Safe for emergency cooking and drinking if something bad were to happen.

I'm no expert on water storage so this is a good solution for me. Hope I never have to find out how well it works.

I have heard from other people (that are educated about preparedness) that this is a
'must have' item for storing water safely for several years.
My bottle of water preserver came on time and it is lightweight.
It should be very useful for my water storage.

I have not tried the product, I intend to use it in an emergency in the future. I placed it in my earthquake emergency kit. I think Californians should consider this specially if you have kids or elderly in the family.

This product is easy to use and does what it claims. My only word of caution is that this product does have an experation date so plan to use it within a few months of purchase. Other than that, great purchase!

If you have decent water now, buy this and a water safe 55 gallon drum, and dump the entire contens into the barrel first, fill, seal, and label drinking water exp 5 years down the road. For a family of 4, that's roughly a 2 week alternative to drinking fecis, and bug laden city water after a full scale power outage, man made, or natural disaster.

Easy to use, however I don't know if it works. I'll let you know in 5 years. I started with good DISTILLED water and not crappy floride filled tap water.

since i just put this in, can't really say whether its really working or not. if this review is still available about 5 years from now, i will let you know if the water preserver actually works. just a FYI, i cleaned out my 50 gallon water drum with a little bleach initially and rinsed over and over again. i then got about 5 gallons of purified water (reverse osmosis) per day out of my home system over a 10 day period to fill up the whole drum, then added this solution. so in reality, should be good after 5 years, but who knows until we re-open and pump some water to test. i will say easy to use.

tHE 55GAL. WATER PRESERVER CONCENTRATE IS A MUST FOR ANY LONG TERM STORAGE. I HAVE ADDED MINE TO MY STORAGE DRUM THE DAY I GOT IT. I SEE THAT THE BOTTLE HAS AN EXP. DATE OF ONLY A YEAR. THIS IS A PROBLEM FOR THOSE OF US THAT WOULD LIKE TO ADD THIS TO OUR WATER STORAGE RIGHT AFTER A DISASTER.
