i was mixing some salt in a rubbermaid tub with an overpowered pump which turned up and sprayed 10g of water all over the living room. my landlord phoned me at work to tell me the residents below were having water come thru their roof. (i was 2nd level). har har! I thought my tank broke so I can burning home to find that...I didn't tell them it was saltwater
so needless to say, 2nd floors don't hold water that well
