Thanks Richard,
The alarm is a good Idea.
Was a pan required in 84?
If you have a slab and the water heater is located in the middle of the unit. How would you install a drain to the exterior if it had to be brought up to code. You would have to cut a troth.
I would say yes to that as would any remodel job.
Tim thanks for your reply but it's not a "remodel" but a "replacement".
In the last ten years I only know one person that said they got a permit for replacement, and they could have been pulling my leg on that.
I don't know of anyone getting a permit when they replace there Heating and Air either. These are reputable company's doing these replacements and you would think there business is on the line.
I think in reality that the AHJ doesn't push for and turns a blind eye to-wards "replacements".
