When a DeWitt water heater leak is on National Grid's list
Water keeps running from the base of a gas water heater in a DeWitt basement. That is not only a plumbing problem: National Grid lists a continuous flow of water from a gas water heater among its gas emergencies, along with a flame that looks abnormal or appliances losing gas. If you smell gas, get everyone out, touch no switches, and report it to National Grid or 911 from outside. With no smell, turn the heater's gas control to off, close the cold valve on top, and keep people away from the scalding drain valve. Then the water side is a licensed plumber's job.
What water heater emergencies involves in DeWitt
What in a DeWitt gas water heater emergency is yours to arrange
About 79 percent of DeWitt households heat with utility gas, among the highest shares in this metro, in housing with a 1963 median. National Grid's rule for those homes is clear on ownership: the customer maintains the gas piping from the outlet of the meter onward, so the line to the water heater is yours to have checked. That splits the job cleanly. National Grid deals with a gas emergency. A licensed plumber makes the tank safe and stops the water. The replacement heater, its venting and its clearances, needs a county permit and is quoted once the leak is under control.
Smell first, then touch
Any smell of gas means out of the house before anything else. No smell means the gas control, then the cold valve.
A drip is not a flow
A few drops from the relief pipe is worth a look in daylight. A steady flow from the tank is the case National Grid lists, and a reason not to wait.
The heater's gas line is yours
Beyond the meter outlet, National Grid puts the piping on the customer. If the plumber finds a problem with the line, that is a separate repair to quote.

National Grid states it is the customer's responsibility to maintain gas lines that begin at the outlet of the gas meter and extend above or below ground on the property, and recommends periodically hiring a professional plumbing or heating contractor or leak survey expert.

DeWitt questions about gas water heaters and National Grid
Should I phone National Grid about a leaking water heater if I cannot smell gas?
If the leak is a continuous flow, it is on National Grid's own list of gas emergencies, so reporting it is reasonable. If it is a slow drip and you have turned the gas control off and closed the cold valve, the tank is safe and the plumbing side can be booked.
Can the plumber just put in a new tank tonight?
Not without a permit. Onondaga County requires a plumbing permit before a new water heater goes in, because wrong connections, venting or clearance can cause shock or fire. Tonight is the safe part; the replacement follows.
