Question by porcelainity: Electric hot water heater–should I replace or repair?
I have an 8 year old Marathon 80 gal. tank and it works perfectly. But on the hot water to in-house pipes (which comes out of the top of the heater and are PEX tubing), there is a 5 inch copper attachment or extension that water flows through ( what could it be-overflow?) that has corroded badly and the corrosion has dripped down and discolored the hot water tubing. Should I replace the part and tubing, or simply get a whole new heater?
