Water Heater Installation
If you arrived here from my Mobile Home Doctor website you know I have some experience with replacing water heaters. When the water heater in my house recently failed I replaced it. I thought it would be a two hour job; it took seven! I was reminded that instructions for how to install a water heater don't begin to describe the reality of the experience.
The fact is, every house is different so a water heater installation "cookbook" can only go so far. In addition, repair people forget the tools, techniques, and assumptions they bring with them to a job so it is hard for them to remember the many things they do without thinking about it. I had been away from this kind of work for several years so I was forcefully reminded of what I had forgotten.
I think you can learn two valuable things by reading about my experience:
Disclaimer: There are many codes, rules, and regulations related to installation of water heaters, especially gas fired ones. They are different from location to location. You will have to be sure you or your repair person do what is required where you live.
