A friend's 16 year-old gas water heater started to leak a few days ago. The water has corroded through the outside shell. Fortunately it's a slow leak.
The water heater stands on the floor and has no pipe connected to the pressure relief valve. There is no pan under it.
Would the hvac contractor want to add a pipe from the pressure relief valve to the outside? The water heater is in the middle of a finished basement and the overflow pipe would have to go through two walls in living space to get to the outside. It would be pretty ugly. Can the pipe drain into a sewer pipe in the laundry room?
Is there any extra-cost features worthy of considering over a no-frills hot water heater?
