Hot Water Tank is Leaking Water | Repair and Replace


Hi, I’m Vance and welcome to Repair and Replace. If you find water underneath your water heater, it doesn’t always mean that
the tank needs to be replaced. It might just be a simple fix. In this episode, I’ll show you where to look
to narrow down the leak. The temperature and pressure
relief valve is one of the most important safety devices in your
water heater. If the tank heats up and the pressure
gets too high, the valve will open and release water,
preventing the tank from exploding. After the valve discharges, it should close
all the way. There shouldn’t be any water dripping out. First check the drain tube. If you can feel water dripping then
it’s possible that the spring is corroded and the valve is not closing properly. Additionally, check to see if there’s any
water leaking around the threads. If there is a slow continuous leak then it’s
best to replace the relief valve. You can see how to do this in the
video linked in the description. Now if the relief valve opens
intermittently or even daily, then its most likely an due to
normal water pressure expansion. This can be fixed by installing a
diaphragm-type expansion tank on the cold water supply line. In these cases its best to call a technician. The drain valve is used during regular maintenance
to drain and flush the tank. This valve is often made out of plastic, which
can crack overtime. It’s recommended to install a brass drain valve
as these are the most reliable. First check to see if there is any water inside
the outlet. Now check around the valve to see if there
is any water coming out of the threads. If you see any water, then replace the drain
valve. You can see how to do this in the video linked
below. Water can also leak out of the cold supply
inlet and the hot water outlet pipes. First check the threaded connections into
the tank. Now check each connection between the pipes. If there is any water then it should be fixed. This is often best handled by a technician. If you didn’t find water coming out of any
other connection, then it could be the inner tank. Remove the door cover. If the insulation is wet, then it’s possible
that the inner tank has rusted out. At this point it might be best to get a new
tank installed. Hopefully this has helped you narrow down
the leak in your water heater. If you liked this and want to see more tutorials and informational videos, then subscribe to
