Frozen and Burst Water Pipes in a Syracuse Winter
Almost always because the freeze is on your side of the curb stop, and depth is usually the reason. Onondaga County sets minimum cover for a domestic water service at 54 inches and OCWA's customer rules require the same four feet six inches, so a line laid shallow, or shallowed later by an excavation, a regraded driveway or a new patio, is the one that freezes while the street carries on. Inside the house the same thing happens in the places the state code says supply pipe should not be: outside walls, attics and crawl spaces.

What to establish first when the water stops in a cold snap
Do the neighbors have water?
One knockA street wide loss points at the main. The city records about 200 breaks a year and 47 percent of them fall in the four months from December through March.
Does one fixture still run?
Two minutesPartial flow points at a run inside the house, usually in an exterior wall, an attic or a crawl space. Nothing anywhere points upstream, at the service line.
Find the first indoor valve
Before it thawsA frozen pipe that has split releases water when it thaws. OCWA requires a shutoff inside the building wall no more than 12 inches from it, and that is the valve to close.
Call the purveyor, not a plumber, if it is the street
Costs nothingThe City of Syracuse emergency line is answered around the clock on 315-448-8360; OCWA answers after hours and weekends on 315-475-7601.
If it is your line, the fix is depth
The county's own guidanceSection 5.5 cautions that insulation board over a shallow line carrying little flow is not effective in Onondaga County, because such a line has no self heating effect.
The trench stays open until it is inspected
County ruleEmergency work may proceed with the permit obtained on the first business day after, but nothing may be covered, backfilled or concealed before Plumbing Control has inspected it.
Onondaga County Requirements for Implementation section 5.5 and Plumbing Control permit conditions; OCWA Customer Rules sections 4.5, 4.6 and 4.7; City of Syracuse open data and Water Department; NOAA 1991 to 2020 normals for Syracuse Hancock International Airport.
First decide whether this is your house or the street
Two checks separate a plumbing problem from a water main problem, and both are unpaid. Ask a neighbor whether they have water, and try more than one fixture in your own house. A street wide loss, or water that comes back brown for everyone at once, is the main. That is a seasonal event here rather than a rare one: grouping the 3,042 breaks in the City of Syracuse open data set for 2004 to 2019 by month gives 424 in January, 420 in February, 305 in December and 281 in March, against 167 in September and 161 in October, so the four months from December through March carry 1,430 breaks, roughly 47 percent of the total, in a third of the year. The City publishes an emergency line answered around the clock on 315-448-8360, and OCWA has an after hours and weekend emergency answering service on 315-475-7601. Making that call before you call anyone else is what stops a homeowner paying to investigate a fault that was never theirs.
Depth is why one house freezes and the one next door does not
Section 5.5 of the Onondaga County requirements sets minimum cover for a building domestic water service with normal flow at 54 inches, and puts fire service lines, yard piping and lines with little or no flow deeper still at 66 to 72 inches, adding that designers and contractors should allow extra cover for local conditions such as wind exposure and large paved areas. OCWA's customer rules land independently on the same figure, requiring all customer service pipes to have a minimum ground cover of four feet six inches. That number exists because of what winter does here. The NOAA 1991 to 2020 normals for Syracuse Hancock International Airport give 132.5 days a year with a minimum at or below 32 degrees Fahrenheit, 57.3 days at or below 20, 7.7 days at or below zero, and 46.8 days on which the maximum never rises above freezing, with a winter mean minimum of 19.2 degrees and normal annual snowfall of 127.8 inches. Frost is driven into bare, plowed, wind exposed ground far more than into ground under undisturbed snow, which is why a line under a scraped driveway behaves differently from the same line under a lawn. A house that froze once and has not been made deeper will freeze again in the next comparable winter.
Insulating a shallow line does not work here, and the county wrote that down
This is the single most useful sentence in the county code for anyone weighing two proposals against each other. Section 5.5 of the Requirements for Implementation cautions designers that the use of insulation board over shallow lines carrying little flow is not effective in Onondaga County, because lines with little or no flow have no self heating effect and insulation does not prevent freezing. Insulation slows heat loss; it does not add heat, and a pipe with no flow has none of its own to keep. The same section requires water services to enter building walls horizontally at a depth sufficient to avoid freezing, and on shallow foundations or slab on grade construction to rise above the floor immediately on entering the building footprint. Inside the house, section 305.4 of the Plumbing Code of New York State is just as direct: water, soil and waste pipes shall not be installed outside a building, in attics or crawl spaces, concealed in outside walls, or in any other place subject to freezing temperatures unless adequate provision is made to protect them by insulation or heat or both, and exterior supply piping shall be installed not less than 6 inches below the frost line and not less than 12 inches below grade. So if a quote for a repeatedly freezing service proposes wrapping it rather than lowering it or rerouting it, the county's own guidance says that will not hold.
The valve to find before the thaw, because that is when it floods
A frozen pipe is often not the emergency. The emergency arrives when it thaws and a split section starts delivering water into a wall or a ceiling, and at that moment the only thing that helps is a valve you can reach in the dark. OCWA requires the customer to install two shutoff valves at the customer's own expense, the first inside the building wall and no more than 12 inches from it, the second next to and on the outlet side of the meter, both of an approved make and type. That inside valve is yours to operate. The curb stop is not: section 4.4 of the same rules reserves it exclusively to an employee of the authority and section 9.1 lists tampering with authority equipment as grounds for discontinuing service, so the answer to a burst pipe is never a long wrench and a guess at the lid in the sidewalk. If the water is running and the valve will not close, that is the call to make to the purveyor, since OCWA will shut a service off at the road for a customer getting ready to make a repair.
Nobody is filling the trench tonight, and that is the rule working
When a service line has failed under frozen ground, the work is an excavation and it runs on the county's clock rather than the weather's. Plumbing Control requires a permit before any work except an emergency, requires an emergency permit to be obtained on the first business day following, and states that work cannot be covered, backfilled or concealed before an inspection has been done, with section 3.1.B of the county requirements saying the same thing for emergency repairs of water services. So a contractor who closes a hole on a Saturday night has made the work uninspectable, and it has to be opened again. The other half of the rule is who may be standing in the trench at all: homeowners are prohibited from doing any type of plumbing work outside the house, and only a holder of a county Certificate of Competency may obtain the permit for it. A winter service line failure is therefore a permit, an open excavation, an inspection and then backfill, in that order, and any offer that skips a step is offering a code violation rather than speed.
If the house is going to sit empty and unheated
The cheapest repair is the one that never happens, and for a seasonal property or a house between occupants the decision is about the meter. OCWA advises that a property left with the heat on can simply have the water shut off at the road or the valve closed at the meter, with the minimum basic system fee still billed every three months, but that where there will be no heat in the dwelling the meter should be removed because it might freeze. There is no quarterly fee once it is out and a 70 dollar charge to put it back. That is worth setting against who pays when a meter does freeze: OCWA maintains meters at its own expense for ordinary wear and tear, but damage due to freezing, hot water or other causes is repaired or replaced at the customer's expense. One more piece of timing, for anyone whose line is limping rather than broken: section 4.7 of the customer rules says the authority is not required to install any service connections between November 15 and April 15 except by special arrangement, in which case the customer pays the excess over normal costs. A service that is failing in October is a far easier job in October.
