you find water on the floor near the water heater, it means that water is seeping from the tank. The water could be coming from a loose valve or from a leaky pipe. If you don't see any leaky pipes, you can try tightening the valve. If this valve is loose, water might leak out of the heater. Otherwise, the leak might be caused by a faulty valve, an obstructed vent or a defective heating element. the water isn't hot enough, the first thing to do is check the thermostat. If the thermostat is set correctly, try to remember when you last flushed out the tank. Mineral build up inside the tank can keep the water from heating up properly. If your tank doesn't need flushing, you might want to check the heater's dip tube. If the dip tube is broken, the water won't heat up properly. You can check the dip tube by removing the cold water supply line and taking the dip tube out of the tank. For more detail visit http://dubaielectronicsrepair.ae/ And contact# 0509173445
