Ok,.. so this is a strange one, but bear with me.
My dad lives out in the countryside & his house & 30 of his neighbours share a "Group water scheme",.. basically one well/borehole was dug & they all share the cost of running it. He's been landed with the job of testing the water quality recently, and has got his hands on some lovely little chemistry set type things for testing for contaminants etc. Being interested in water for my business I got him to check the water in my tank (His gadgets are much more advanced than out TDS meters!)
My TDS is reading 000 - but it turns out that there is a significant amount of dihydrogen monoxide in my water! (for info see
http://www.dhmo.org/)
I checked the water straight after the ro (before DI) and it was still present,.. and its also present in the waste water! I've recently changed a membrane (about a month ago) and was wondering if there could still be traces of it coming out of the membrane? Obviously I'm more than a little concerned about this since I'm working with it daily!
