Customers water heater was old and leaking at bottom. Gave a few options to replace. Replaced heater with Rheem 40 gl gas short. Also installed new TET with bracket and ball valve. While replacing heater found vent coming from heater to be damaged, replaced section all the way to wall to section. vent in its entirety seems to be issued due to back draft from heater when heater was turned on. Suggest to have a HVAC company come to assess vent line and possibly clean or replace. After install checked for leaks and proper function.
