There are many points in the house from where you can find the leaks. These are easily detectable and can also be solved. However, these places are not always visible as they occur at hidden place so can slowly and steadily cause major damage.
You should keep a check on it by checking your dishwasher, washing machines, toilets and other water related appliances once a month as there may be some leaking in one of it. The different signs which show leaks are:
1.Toilets running uselessly.
2.Dank odour in the floor.
3.Increase in water bills without any reason.
You can also find them by closing all the water appliances and then checking the water meter. If there is and increase then there is a leak and you have to find it and get it finished.
