Most of the houses I have lived in have been over 20yrs old at least. The downsides of renting I guess. What about the ones coming off the hot water heater tho? All hot water would have to pass through them wouldnt they? All the ones Ive seen have been copper. Im not sure where Aust. laws stand on this. Are copper tests available? If so, I should totally buy one and test my hot water.
Anyway, indydoug, you are doing a great job and at least those fish were sold to someone with sense enough to do more research like yourself than to some of the dolts I have encountered that have no clue and dont seem to care. Good job, those fish struck it lucky with you.
