The formula is   500000 divided by TDS in per 25 ltr bag.

So you should get approx 9000 ltr pure per bag.

Around £9.00 per 1000 ltrs at approx £80 a 25ltr bag.

If you buy Ro'd water its usually about £15 ish per 1000 ltrs so thats not too bad for you.

My tap TDS was an average of 45 - until it rained! once it rains your TDS can go up by at least a hundred so keep an eye on it
