Skaneateles Lake water, and what it does to a tank
Two local things decide a heater job at a city address. The first is the water: Skaneateles Lake arrives at 127 milligrams per liter total hardness, about 7.4 grains per gallon, which is enough to lay sediment in the bottom of a tank over years and to scale an element, and not enough to make treatment equipment a health purchase. The second is the permit, because Onondaga County requires one before a new heater is installed and attaches a photographic checklist to it, which makes the highest volume job in the trade a documented job here.
What water heaters involves
Repair the tank you have, or replace it
Start by ruling out the things that are not the tank. Rusty hot water in the days after a main break is usually sediment drawn in from the street, and the sensible move is to clear it from a cold tap rather than by running the hot, which pulls it into the heater where it settles and stays. A tank that rumbles but still heats generally wants flushing. Where the heater genuinely has reached the end, the city's lead notice is the reason to care about the thermostat setting: lead dissolves more easily into hot water, and the county checklist asks for 120 degrees in any case.
Ask whether the quote priced a permit or skipped one
Plumbing Control requires a plumbing permit before a new water heater goes in, because incorrect connections, venting or clearance can cause shock or fire and a small error on a gas heater can cause a poisonous leak. A heater swapped in without one is an unpermitted alteration on your property.
Check the service for a pressure reducing valve
The county checklist requires a thermal expansion tank wherever a pressure reducing valve is present, and a photograph of the water service to show it. That is the line item a cheap quote leaves out, and it is often the whole difference between two numbers that otherwise look identical.
Use the cold tap for drinking in an older city house
The Water Department's own notice tells residents to use cold water only for drinking, cooking and baby formula, to flush the pipes before drinking, and to clean the aerators regularly. Boiling does not remove lead. That advice holds whatever heater you end up with.
Hardness, the checklist and the city lead notice
The City of Syracuse 2024 Annual Drinking Water Quality Report gives total hardness of Skaneateles Lake water as 127 milligrams per liter, with an average pH of 7.89 in a range of 7.63 to 8.38, and sodium at 12.8 milligrams per liter. Skaneateles Lake is described as a very high quality source requiring minimal treatment: chlorine for disinfection, fluoride, and orthophosphate for corrosion control.

The City of Syracuse Water Department's public notice on lead tells residents to use cold water only for drinking, cooking and making baby formula because lead dissolves more easily into hot water, that boiling water does not remove lead, to flush the pipes before drinking by running a tap or doing laundry or dishes, to regularly remove and clean the faucet screen or aerator where sediment and lead particles collect, and to use a filter independently tested and listed for lead removal and never run hot water through it. The notice also states that homes built before 1986 are more likely to have plumbing containing lead.

The City of Syracuse Water Department application aid states that for a domestic water service in the city the plumbing permit number is pulled by the licensed plumber from Onondaga County Plumbing Control on 315-435-6614, and that a licensed plumber is required to get the permit and perform the work in the City of Syracuse. The same document warns that services may take four to six weeks to be installed after the permit is completed, so plan accordingly.

Onondaga County Plumbing Control states that a plumbing permit is required prior to the installation of a new water heater, noting that improper installation through incorrect connections, venting or clearance could result in electrical shock or fire and that a small error installing a gas water heater could cause a poisonous leak or explosion. A permit is also required before installing a new plumbing system or an upgraded or changed system, even where the homeowner is doing the work.

The Onondaga County Residential Water Heater Permit Checklist, revised June 2026, must be completed and submitted with the water heater permit application. It requires a full port valve on the cold water inlet, a temperature and pressure relief valve with the discharge tube piped to within 6 inches of the floor and not reduced in size and with no exposed threaded end, a drain valve on the tank, metal hot and cold lines at least 18 inches long on a gas fired tank, the flue or exhaust fitted and supported with three sheet metal screws and sealed, the temperature set to 120 degrees Fahrenheit, and a drain pan where applicable. Photographs of each item are required, including one showing a placard with the date, the plumber's name, the homeowner and the job address.

The Onondaga County water heater checklist requires a thermal expansion tank, properly installed and secured, whenever a pressure reducing valve or a reduced pressure zone device is present on the water service, and requires a photograph of the water service to show it. The checklist also requires a vacuum relief valve on bottom fed tanks or as the manufacturer instructs.

Rumbling, or actually finished?

What Syracuse homeowners ask before buying a tank
Do I really need a permit to swap a water heater in the city?
Yes. Onondaga County Plumbing Control requires a plumbing permit prior to installing a new water heater and publishes a residential checklist that is completed and submitted with the application. Inside the city line the permit number is still pulled from county Plumbing Control on 315-435-6614. Only a holder of a Certificate of Competency may obtain a contractor permit, so the contractor who takes the job is the one who applies, and obtaining a permit on behalf of another party is an offense in its own right.
How long should a tank last on Syracuse water?
Nobody can put a number on your tank honestly, but the direction of travel is published. City water measures 127 milligrams per liter of hardness, roughly 7.4 grains per gallon, which sits at the gentler end of this metro and is still enough to build sediment and scale an element. An annual flush and an anode rod check change the answer more than the brand does, and they cost a fraction of a replacement. A tank that rumbles and still heats is a flush before it is a purchase.

No hot water, not enough of it, or water on the cellar floor. Each one means something different.
