How I changed the sacrificial anode rod in my 7 year old natural gas fired RHEEM Professional Classic Plus Series 40 gallon hot water heater. #plumbing #waterheater #homeappliances

Alright today on Repairs101 I’m going to change the sacrificial anode rod in this gas fired hot water heater.

A sacrificial anode is made of zinc, magnesium or aluminum alloys that attract iron and limestone and things like that in water via electrolysis and sacrifice itself via corrosion.
Read the instructions on the tank.
Turn off the burner, then shut off the gas supply.
Then shut off the water supply and open a tap to depressurize the system.
Grab a good size bucket and drain off about two to four gallons. Don’t worry; when the pressure relief valve opens it will flow quickly.
I tried to break the torque by hand but you can see I moved the whole tank.
“Oh dear. OK. That’s no good.”
Though my impact gun had it out in a few seconds. But I did need a rare earth magnet to be able to grab onto the fitting and pull the rod out.
You can see after seven and a half years, this one is well corroded.
I put a little PTFE thread sealant tape on the threads before dropping the rod in, spinning it down and giving it about a ninety degree torque turn.
Again: read the instructions on the side of the tank.
Open the fuel supply.
Press and hold the PILOT button on the gas cock valve.
Press the piezo igniter until you have a flame.
Hold the PILOT button for 45 seconds.
Turn the gas cock knob to ON.
And so all that’s left is to turn the water back on and purge the air out of the system.

what size socket did you use?

[@repairs101]

1 & 1/16" - 6 point chrome socket - there wasn't enough clearance for an impact socket so I turned the power on my impact gun down a bit.

@@repairs101 ok, thanks for the info, i dont think my air hose can reach far enough so i might have to use my corded electric impact.

That rod sacrificed itself for the survival of the hot water tank. I hope it was given an honorable burial.

At the shipyard guys collect up all the bits of old anodes to melt down and sell as ingots, or to cast new anodes.

Why do you need to heat hot water, I have never needed a hot water heater😅

[@repairs101]

You make a fine point. I'll talk to the headline writers downtown at our Department of Redundancy Department on Monday morning.
