Leaking water heater?
The location of the leak plays a major role on whether your tank is repairable or must be replaced.
If your tank is leaking from a pipe attached to the very top or the side of the water heater that runs down to the wall or floor and to the outside also known as the temperature pressure relief valve and overflow pipe, you may not need to do anything.
If the water is coming out of the pipe itself, this means the tank is under extreme pressure or it may be way too hot inside and has released the water for safety. This may be due to 2 problems, incoming pressure too high or tank is overheating. If the leak is coming from a connection outside the tank, it should be able to be repaired.
If the leak is coming from the bottom of the tank or seems to be coming out from underneath it, this means the internal tank has cracked and needs to be replaced.
No hot water?
When you take a shower, bath, or simply use a faucet and notice there is no hot water, this can mean a few different things. Check to make sure no one else in the household used up all the hot water. If this is not the case, your pilot light may simply be out. The pilot on a water heater stays on continuously and helps with turning on the burner when the thermostat in the water heater senses that the water in the tank is not at the set temperature. There is a lot more mechanics that go into this, but for simplicity’s sake this is how it typically works. If your pilot light is out, the first thing you should do is re-light the pilot
