我Google了一下,水管的热水确实不应该食用。 4 reasons why you shouldn’t drink hot tap water Here are four reasons why you should not drink hot water from the faucet or use it for cooking. The heated water may cause the plumbing to release harmful substances such as lead and nickel [2]. Cold water is fresher. Hot water stays in the plumbing system for a longer period of time to get heated. Longer stagnation time in the system may cause higher bacterial levels.[3] Hot water is exposed to more pollution sources since it passes through additional tanks or heating systems.[3] The level of microorganisms is higher in hot water plumbing. In multiple studies carried out by Lee [1], [4], it was found that the temperature appears to have an important impact on bacterial activity and also corrosion rate in the pipes (tested on PEX, copper, stainless steel, carbon steel and galvanized pipes).
哦,好的吧,祝你家喝的开心
他是来挖坑的。
现在还有含铅水管么?
国内应该没有了 美国很多老房子还是含铅水管
也许真的是喝热水,喝得脑子坏了
老一点的房子热水管怎么焊接的?
如果大building的集中供水的,更不能喝。里面时常有死老鼠。
我为什么知道的?以前我一直喜欢去超市打水,我后来发现墨西哥人和印度人很多,有次我跟墨西哥人聊天,他说他们以前常弄water heater, filter,或者有朋友在水塔或污水处理厂工作,这些累活都是他们干,不管来自哪里,管子里出来的都别喝
你应该问水厂干脏活的墨西哥人 而且你家里的热水来自water heater,你别告诉我,你每年没有放water heater的污水?
深井冰
你家的热水是你家的热水器出来的,和水厂无关
看情况有点了
水龙头的冷水随便喝吧。
不懂就问 镁离子对人体无害吗
可是漱口呢? 我习惯用温水漱口。
这样的水管最好换掉,含铅的水管不管凉水热水都对身体不好。
这么说来,凉水也脏啊😨
需要每年放水么?怎么放?
底部有个阀门叫做 drain valve ,维护得好的人,每年都会放次水,还有加热棒,每隔两三年也要看看
智力暴露贴
我记得我刚来美国时,师兄师姐就告诉我,不要接热水来烧水喝,里面有杂质。
啥,第一次听说,怎么放? 就是请人来clean heater吗?
