You need permit for this

If I were you, I will just take couple of pumps over there. In an hr, I can all the waters out to street. And put a floor fan there to blow dry.

Then check his items that damaged. 就是為了心理有個數。

這是天災，你不用賠他。看一下，拍照片。 為了不被他訛詐。

你可以帶給a carmer and a smart switch over. 那樣可以遠程控製。抽完水就走人。幾天後再來看，把東西都拿走。

這一套設備也就三百塊。而且可以隨時用。
