You will almost certainly need a large socket and a 24" breaker bar. Loosen only a turn, then drain the tank. You first turn OFF the power to tank, then attach a hose pipe to the bottom fitting, lead it outside or to any drain, turn on the valve by it, open the relief valve so air can enter the H/W tank. Let the whole tank empty -takes about 30 -40 minutes. While this is happening pull the anode out and get a new one fitted in. -( About $25 in most Plumbing stores.) Next, when empty turn ON the inlet valve and let cold water run through the tank and out the hose, now you will see the sludge coming out. Let this run 5-7 minutes or until water is coming through clean. Now you are done . Let it fill, then turn on power.
