While feeling a soft spot or warm spot in your floor might indicate a leak, it doesnât necessarily indicate where the leak is located. Water has the ability to travel quite a distance before making an obvious sign. Locating a leak under a slab is a two step process. 1. Locate your houseâs pipes. 2. Use an electronic leak detector to pinpoint the location of the leak.
The FDA RACC (Reference Amounts Customarily Consumed per eating occasion) for fruit juices normally used as ingredients (such as lemon or lime juices) is 5 ml per occasion, so about  15 ml per day.
Most recommendations range between 1 to 4 tablespoons per day, diluted in water or juice. I wouldn't really recommend more than that myself, for internal use. If you are trying to lose weight, try drinking 1 tablespoon in a large glass of water 3 times per day. Many people find it easier to drink if you squeeze a little lemon in the glass, too.
