Supermarket water containers for storage

[mark freshwater]

Hi ,
my local supermarket has 10 litres of water for $3 , once finishing drinking the water can i reuse them for ro/di storage if i use said ro withing 2 weeks , or are they a one use only.
Would be alot easier for me to carry upstairs.
Thanks Mark

I assume that the plastic used is food grade, if it is, use it for storing water for our tank is fine. Reefers have used non-food grade plastic container for water storage or sump for our system forever without apparent problem.
10 gals to carry upstairs is a lot of weight for me, but if you are a strong guy, I say go for it.

I missed read it. I can handle 10-11 kilo fine. I am sure you can too. It is the 10 gal container full of water that will give me problem.
Isn’t metric system easy. 10 litter of water is 10 kilo of water. Salt and container add slightly more to it.
