Shutting down a leaking tank in Marcellus
Water is pooling around a Marcellus water heater. Use the heater's own control, gas or electric, to shut it down, but skip the breaker if the panel is wet. Next, the valve on the cold pipe feeding the top of the tank. The water inside stays hot for hours, so nobody opens the drain valve.

What water heater emergencies involves in Marcellus


Older Marcellus village houses and the rental rule
Village homes are old, a 1952 median, so that cold valve may be stiff; if it will not turn, close the main. Where the house is rented, New York's maintenance code puts water of at least 110 degrees at every tap on the landlord, and a new tank waits for a county permit.
What older Marcellus housing means at the tank
ACS 2020 to 2024 estimates put 487 of the Village of Marcellus's 1,004 occupied units, 48.5 percent, as renter occupied, with a village median year built of 1952 and 38.4 percent of units built in 1939 or earlier. The Town of Marcellus is 21.6 percent renter occupied with 31.8 percent built before 1940.

Section 505.4 of the 2020 Property Maintenance Code of New York State requires water heating facilities to be properly installed, maintained and capable of supplying water at every required sink, lavatory, bathtub, shower and laundry facility at not less than 110 degrees Fahrenheit, and requires an approved combination temperature and pressure relief valve and discharge pipe to be properly installed and maintained.

Marcellus water heater question
The cold valve above the tank is stuck. What do I close instead?
The main valve where the service comes in. If that will not close either, OCWA can shut the supply at the road.
