Well if it is a temporary thing, go get those 5 gal bottles of drinking water.

BUT ..... RO and I assume distilled water, have NO minerals in them and you will need to replace the micronutrients if using long term. Particularly calcium and magnesium which work together. Simple unsulphered molasses 1 tsp per gal will resolve that.
