Don't invite him to the house warming party ?With regards to the potable thing, I've just had an interesting (or boring depending on how you look at it) conversation with a neighbour who used to supply tanks to farms. He says that a non potable tank won't change the TDS of the water but it will affect the PH levels. While it might still read 0TDS it won't necessarily clean in the same way. He reckons it should still dry spotless but wouldn't necessarily attract dirt in the way the fresh pure normally does. If it was being used for tropical fish for example the PH would be too high and it wouldn't be fit for purpose.
