John wood water heater service call Upon arrival, unit is working but customer had concerns of corrosion on tank. Both inlet and outlet of the tank are very corroded and could develop a leak in the future. The tank is 10 years old and don’t recommend fixing the tank due to age. Quoted new pv 60 and Pv 50 tank for the customer. Tank is a rental and customer is double checking with rental company to ensure the tank is bought out before we install.
