IF u think that learning about the poison level and check the copper content in the water by the indicator is not a good method.
Of course, u can. But at least I tried to help and solve the porblem. And tell how poisoning the copper is. And provided a possible methode to test.
But.....

唔使argue la
你又知你家係用緊銅喉?
你有冇讀cert level chem?
冇乜可能用銅wor
1. 重, 多數喉管都係外掛於大廈外牆，重好就難固定
2. 軟, 硬度都不能承受本身重量, 大廈拱水系統起喉咁長起碼過百米lever arm 咁長好易彎
3. 貴, 用來構造一個供水系統既銅比起同一份量既stainless steel貴多多多聲
4. low corrosive resistance, 唔耐用....
Ah
