Tap water

[Scavenger]

I'd run down to your nearest Super Market and buy some RO out of the dispenser machine. If you already got the bottle it should be only $2 for 10 gallons. That would be safer until you get RO unit up and running again.
I learned the hard way, leave the tap water in the tap! And where I live in Nanaimo, I have good quality water that runs through in house filtration too. It was just algae city!!
