Plumber just came out and told us our water heater isn't connected to the vent at all and has been leaking Carbon monoxide since we got it put in, which was 5 months ago. Restaurant Owner says we can only be shut down until it's fixed (and then re-open once it's fixed aka 2 hours from now) The reading is 102.7 near the water heater with the detector. Anything I can do??
