My 22 year old home is not really 'tight'. On the west coast, it is not desirable due to the prolonged wet winters that we have here - mold growth can be problematic. None apparent in my house so it must be working OK as it is.
Speaking of excessive regulations. BC upgraded its drinking water standards recently. Despite the fact that our drinking water in the Comox Valley is some of the finest in the world & plentiful, we have been on a 'Boil Water Advisory' for a month now because of 'turbidity' issues. CYA at work IMO. It is not the first time in the past century that it has rained hard here & caused slight turbidity - but now the panic is on. It is a complete PITA for restaurant & pubs to keep up this nonsense.
Rest assured, we are not boiling our drinking water in our house & we are still upright. Interestingly, there are reports of people getting sick from just brushing their teeth with tap water. Ya, right...
