Tankless Water heater Leak - 2021 Bambi 16RB
After 3 months and over 20 days uses, I've got a pinhole leak in a copper water line which looks to be coming from copper holding tank for tankless water heater. Only sprays when water pump on. Airstream maintenance extremely backed up and can't drop off for warranty work until mid May; many trips planned before.
Looks like I can access water pump through my closest if I remove some screws and panels. Will Flex seal tape get me by before warranty repair? Any advice on how to access water pump from the rear; the leak is on right side of unit near back. Unable to reach from front access panel.
