We need to replace our anode rod for the water heater. There is no part # on the anode rod. We Googled 2017 Redwood 38GK model and it said the part number was 232767. When we search for this part number online we get a wide variety of rods with different lengths that differ from the one we have. How do we actually determine which one to buy. We have looked at the local hardware stores and can't find anything, so it appears we'll need to order it online. Can you help guide us with this?
