Winter plumbing checklist for Tredyffrin and Easttown: frozen pipes and meter pits
Pipes are most at risk when temperatures stay below freezing for about 72 hours or longer. Before that happens, drain outside spigots, check any outdoor meter pit lid, insulate exposed pipes, and know where your main shutoff is. The first sign of a freezing pipe is reduced flow at a faucet.
Key takeaways
The short version
- Risk climbs after about 72 hours below freezing.
- Drain outside spigots and disconnect hoses in the fall.
- Make sure any outdoor meter pit lid is intact.
- Reduced flow at a faucet is the first sign of freezing.
- Never thaw a pipe with an open flame.
Why a long cold snap is the real danger
A single cold night rarely freezes pipes in a heated house. Sustained cold is different. During the late January 2026 cold, the City of Philadelphia warned that pipes are most at risk of freezing or bursting when the temperature does not go above freezing for 72 hours or longer.
In T/E, the pipes that freeze first are the ones exposed to outside air: lines along exterior walls, in crawl spaces and unheated garages, in sunroom additions, near drafty windows, at outdoor spigots, and at meters in outdoor pits.
Where T/E pipes freeze first
Every house has its weak spots, and the age of the house tells you where to look.
Postwar homes
In Strafford Village and similar 1940s and 1950s neighborhoods, pipes often run along exterior walls and through older additions and porches that were enclosed later.
Townhomes and condos
In Chesterbrook, pipes in exterior walls and in units over unheated garages or entries are most exposed, and a burst can affect neighbors.
Older stone homes
Thick walls help, but crawl spaces, old kitchen wings, and sunrooms often have lines with little insulation.
Newer builds
Hose bibs, garage lines, and pipes near cantilevered floors or bump outs are the usual trouble spots.
Fall checklist: before the first hard freeze
- Disconnect garden hoses. A hose left attached traps water in the spigot, even a frost free one.
- Shut off and drain outside faucets. Close the inside valve for each outdoor spigot, then open the spigot outside to let the line drain.
- Drain sprinkler lines as Aqua advises.
- Check the meter pit lid. If your meter sits in an outdoor pit, make sure the lid is not broken or missing.
- Insulate exposed pipes in crawl spaces, garages, and along exterior walls.
- Seal drafts near pipes, including cracked windows and gaps where lines pass through walls.
- Find, label, and test your main shutoff.
- Test the sump pump and its battery backup before winter storms.
Aqua’s winter guidance for customers has long included keeping heat tape and pipe insulation on hand, marking the master valve, checking meter pit lids, and draining outside faucets. Aqua Pennsylvania is the place to report problems with its meter or main.
Meter pits: the winter risk most people miss
On some T/E properties the water meter sits in an outdoor pit instead of the basement. The pit is designed to stay above freezing below ground, but only if the lid is intact. A cracked or missing lid lets cold air reach the meter and its connections directly.
- Find the pit, usually between the street and the house
- Look for cracks, a missing lid, or a lid that does not sit flat
- Keep it clear of mulch, snow piles, and debris so it can be found
- Call Aqua about a damaged lid or meter, and a plumber for pipes on your side
Philadelphia’s January 2026 guidance also recommended keeping the area around a water meter above 40°F where possible.
During a cold snap: what to do each day
Every evening
- Let a faucet on an exterior wall drip overnight if those pipes cannot stay above 40°F or have frozen before
- Open sink cabinet doors on exterior walls so warm air reaches the pipes
- Check water flow and pressure before bed
- Keep garage doors closed if water lines run through the garage
Every morning
- Check flow and pressure again at each floor
- Look for frost, bulges, or damp spots on exposed pipes
- Listen for water running with every fixture closed
- Check the basement and crawl space for water
Philadelphia’s guidance puts it simply: the first sign of freezing is reduced water flow from a faucet.
If a pipe freezes
If you have no water or very low flow, first ask neighbors whether they have water. If the whole street is out, it is likely a utility issue. If only your house is affected, you probably have a frozen pipe.
- Leave the faucet open so water can flow as the ice melts.
- Apply gentle heat with warm air or towels soaked in warm water, working from the faucet back toward the frozen section.
- Never use an open flame or torch, and never leave a space heater unattended.
- If you cannot find or reach the frozen section, call a plumber.
- Once water flows, check for leaks. Ice can split a pipe that only leaks after it thaws.
If a pipe bursts, close the main shutoff immediately, turn off the water heater, open a low faucet to drain the lines, and call. Our emergency plumbing page has the full first five minutes.
Leaving for the holidays
- Keep the heat on, even if you lower it
- Consider closing the main shutoff for longer trips, and turn off the water heater if you do
- Leave cabinet doors open on exterior walls
- Give a neighbor a key and show them the main shutoff
- Consider leak sensors or an automatic shutoff valve
In spring: check for hidden freeze damage
Freeze damage often hides until spring. A frost free spigot that froze with a hose attached can split inside the wall, so the leak only appears the first time the spigot is turned on, often inside the basement rather than outside.
- Turn each spigot on slowly the first time and check the inside wall behind it
- Look for new stains on ceilings and walls near exterior plumbing
- Watch the water bill for an unexplained jump
- Re-test the sump pump before spring storms
Upgrades that make winter easier
A few permanent fixes remove most of the winter risk for good.
- Frost free spigots, properly sloped so they drain, in place of old standard hose bibs
- Quarter turn shutoffs for each outdoor line, so draining them takes seconds
- Insulation or heat cable on the few pipes that always run cold
- Leak sensors and an automatic shutoff valve for homes that sit empty during trips
- A replaced main shutoff if yours is an old gate valve that will not close
Our plumbing installation page covers these upgrades.
When to call
Low flow during a freeze, or a pipe that already burst?
Frozen is not burst yet, and catching it early matters. Call (610) 788-0042 any hour.
Frequently asked questions
Winter plumbing questions for T/E homes
Answers by John, Tredyffrin Easttown Plumber.
When are pipes most likely to freeze?
When temperatures stay below freezing for about 72 hours or longer, according to the City of Philadelphia’s January 2026 guidance. Pipes on exterior walls and in unheated spaces freeze first.
Should I let my faucets drip in a cold snap?
For pipes that cannot stay above 40°F or have frozen before, letting a faucet drip overnight during an extended freeze helps keep water moving.
What is the first sign of a frozen pipe?
Reduced water flow from a faucet. Check flow before bed and when you wake up during a long cold spell.
How do I protect an outdoor meter pit?
Make sure the lid is intact and sits flat, and keep the pit clear. Report a damaged lid or meter to Aqua.
Can I thaw a frozen pipe with a hair dryer?
Gentle warm air is a common method, working from the open faucet back toward the frozen section. Never use an open flame, and call a plumber if you cannot reach the frozen section.
Why does my outdoor spigot leak inside the house in spring?
It likely froze with a hose attached and split inside the wall. Replace it with a properly installed frost free spigot and keep hoses disconnected in winter.
Should I shut off my water when I go away in winter?
For longer trips, closing the main shutoff limits damage if a pipe bursts. Keep the heat on, turn off the water heater if you close the main, and leave cabinet doors open on exterior walls.
Does homeowners insurance cover frozen pipes?
It depends on your policy and the circumstances, such as whether the home was heated. Check your policy, document damage with photos right away, and call your insurer early.
