In response to Re: State & Local Codes; thermal expansion
The lack of a expansion tank would not cause the failure of the previous tank. The temperature/pressure relief valve would have relieved the temperature build up before failure occurred. If you replaced the water heater because of a relief valve discharge without checking for a bad tank, then that is your problem. But in any case, the municipality will not accept responsibility. They even mark blueprints that they approve that the installing contractor will be responsible for any errors they make in approving the plans. And if you are like a lot of customers, if someone had told you that you needed an additional item that you had not needed previously, you might have refused believing that they were just trying to increase their income.

: After hooking up to public water, my hot water heater had to be replaced due to water in the catch pan. When it was replaced, the new unit released water from the relief valve. The hot water company REP said we were on a sealed water system (check valve/pressure reducing valve) since hooking up to public water. My local plumbing code doesn't mention the need for a thermal expansion tank on a sealed system. The state code does. The local plumbing inspection office says the plumber who hooked me up to public water should have told me about the possible need for a thermal expansion tank. The plumbing inspection office inspector passed the hook up to public water w/o mentioning the possible need for a thermal expansion tank. I had gotten four proposals/bids from plumbers for hook up and none included a thermal expansion tank. The local plumbing inspection office says they are going to require thermal expansion tanks in new homes. My question is: Is the local inspection plumbing office responsible for the damage to my hot water heater (replacement cost) because they knew of the possible problems of hooking up to a sealed system but didn't tell me? If so, I'd like to file a claim with the local government for the cost of the new hot water unit and the cost to install it. Any advice would be appreciated.
