Reverse Osmosis water for flush?

[HoboJoe]

When everything is connected (not in the next week, so not a rush) I will run a test and flush at the same time to make sure everyhing is sealed, there are no leaks ect.

My question is, is RO or Reverse Osmosis water ok for this? I have an RO unit at home that isnt doing anything atm which produces a lovely 0 TDS... not to mention the 20 litres I have sitting in a container at the moment (need to dump this actually).

I'm not too sure... but i'd presume it would be as it is essentially purified water.

i would just pickup a tank of distilled water from asda for £2 and not think about it twice. RO is a purification method but what you want is deionised water as the ions are the ones that can create residues.

And cause corrosion. Plus the RO water is free, and I dont have to get to an Asda

RO will be fine, as is deionised or distilled water. I'd still use a corrosion inhibitor in all 3 though, as even the purest water is still corrosive to copper/nickel.

EDIT: i just noticed you said you were just going to use it to flush the system, in which case any water is fine, even tap water.

Asda do not sell distilled water. They sell Deionised water. Hard to get truly distilled water these days.

well you could distill water yourself to be honest but why go throught that hassle when you can get it for £2?

I've used RO water for flushing and it was fine
