Hello, I am not a DIYer and my 83-year-old father is no longer able to solve problems around the house as well as he could previously, so I am coming here for some help with a leak that is causing my kitchen floor to become extremely damp. Although the water is pooling up beneath the faux wood panels all around the kitchen sink, it is not apparent that there is a leak from the faucet or beneath the cabinets where the sink is located. We also have a dishwasher nearby, but the floor is dry there. The water heater is located in the pantry several feet away, but also does not appear to be a problem. We initially suspected that rain was seeping in from outside, but the concrete pad that the house is built on is several inches above ground. The water has been accumulating for several weeks now and makes it difficult to walk into the kitchen area. What are some possible causes of this problem and how do I go about fixing it? My next step will be calling a plumber, which we really can't afford at the moment. Thanks.

the problem I'm having is after having my sewer lines and water lines replaced awhile back, every time the city's sewer truck comes out to clean out the sewer lines, my toilets blow water and air (including nasty sewer gas smell) The city says it's something to do with the back flow valve I had installed and the company that installed my lines and the back flow valve says it's working right. No one seems to know how or why this happens. the only thing they do say is that it isn't their fault. meanwhile I have to mop up the water each time it happens.
