Atwood uses an aluminum tank so a welder that can do aluminum can weld crack
Otherwise a new tank can be purchased (comes with new insulation, new T&P Releif Valve and 'seal rings'gaskets' needed to attach tank to drawn pan (old rings have to be cut off on combustion/exhaust ports)
OR buy a complete whole new Atwood water heater
(6 gallon fits 6 gallon opening/10 gallon fits 10 gallon opening)
**Suburban doesn't fit either W/O changing size of opening
If current model is prior 2003 then a new Electric/Combo will need 120VAC/12VDC wiring
If current model is prior 2003 and gas only...new gas only is direct swap
If current model is 2004-present---easy direct swap
