我知道water powered backup sump pump的好处,只要有水就会工作.可是我觉得从水管
连一根管子到sump pump,会不会污染饮用水呀?比如sump pump发生故障,水倒流之类的.
一般的battery operated的在连续工作的情况下(比如大雨),能坚持多长时间? | g*****9

briefly, battery back up will work just fine. If out for long time, you will
be better off using a water powered version (you will waste a little clean
water).
It is best to make sure your house is sloped correctly, so you will not have
too much water to pump out to begin with.
的.

不好.我知道有valve防止回流,但是万一有点问题,岂不是喝了阴沟水?
