I had extensive water damage in the back of my kitchen cabinets and lower wall. It seems that there has been a leak in the kitchen for a while. I have lived in my house for four years and went to get something out a lower cabinet that I hardly use. I noticed black mildew and as I took out more of my kitchen items saw it was completely corroded and black and there was black in the back of the wall and a big dent in the middle of the cabinet that was caving in. The land lord had been out once before when I had low water pressure and fixed it and left it at that I called the landlord when I saw the damage and he said he would come the next day after work . He is saying I let the pipes leak and therefore it's my fault although everything directly under the sink was always dry. This true?
