Who do I call for a sewer backup in York, PA?
If only your home is backing up, call a drain cleaning pro: the blockage is almost always in your own drain or sewer lateral, the pipe that runs from your house to the street. If neighbors on your street are backing up too, the public main may be blocked, so call the sewer provider listed on your bill first. Living in the city itself? See drain cleaning in York, PA for who owns the line since Pennsylvania American Water took over.
Inside the City of York, the wastewater system has been owned and run by Pennsylvania American Water since 2022. Most suburban townships and boroughs run their own sewer lines, so the right number is the one printed on your sewer bill.
Why do drains back up so often in York County?
Four local conditions stack up against York County drains. Most competitors never mention them, but they decide which fix actually lasts.
A combined sewer in York City
York’s treatment plant and collection system are a combined system: sewage and rainwater share the same pipes. In a heavy storm, the mains fill fast and water can push back up basement floor drains. Pennsylvania American Water bought the system in 2022 and planned about $17.5 million in upgrades over five years.
Old pipes under old houses
About 1 in 5 homes in York County (20.4%) was built before 1940. Those homes usually have clay tile laterals and cast-iron drains. Clay joints let tree roots in, and cast iron scales up inside until a normal flush won’t pass.
Limestone ground that shifts
Parts of York County sit on limestone and dolomite, which can dissolve and form sinkholes. Settling soil can crack or sag a sewer lateral, and a leaking lateral can speed up soil loss. A soggy or sunken strip in the yard is worth a camera inspection.
The Codorus Creek floods
During Hurricane Agnes in 1972, about 1.1 million gallons a minute spilled over the Indian Rock Dam and flooded the city, causing roughly $10 million in damage in York alone. Heavy summer and fall storms still overload low-lying sewers.
Storm season peaks in summer
The region averages about 44 inches of rain a year, and July and September are the wettest months. That is when combined-sewer backups and floor-drain flooding calls peak.
Grease, wipes and holiday loads
Kitchen grease and “flushable” wipes are the most common causes of main-line clogs everywhere, and York County is no exception. Thanksgiving to New Year’s is the busiest stretch for kitchen-line backups.
Is it my main sewer line or just one drain?
Check how many fixtures are affected. One slow drain is a local clog. Several drains at once, or water coming up the lowest drain in the house, means the main line.
| What you see | Most likely cause | Urgency |
|---|---|---|
| Sewage or water rising through the basement floor drain | Main line blocked, or a storm overloading the sewer | 🔴 Call now |
| Toilet bubbles or water rises in the tub when the washer drains | Main line partly blocked | 🔴 Call now |
| Several drains slow at the same time | Roots, grease or a sag in the main line | 🟠 Same day |
| Sewer smell in the basement that comes and goes | Dry floor-drain trap, or a partial main clog | 🟠 Same day |
| Wet, sunken or extra-green strip in the yard | Broken lateral; in limestone areas, possible soil loss | 🟠 Same day |
| One slow sink, tub or shower | Hair, soap or grease in that branch line | 🟢 Can wait until morning |
| Same drain clogs every few months | Roots in clay joints or scale in cast iron | 🟢 Book a camera inspection |
Who is responsible for the sewer line in York County?
The public main under the street belongs to the sewer provider. The lateral from your house toward the main is usually the property owner’s to clean and repair in Pennsylvania, but where the owner’s part ends (house, curb or main) is set by each local ordinance. Ask the provider on your bill.
| Where you live | Who runs the sewer | Who to call first |
|---|---|---|
| City of York | Pennsylvania American Water (owner since 2022, combined system) | A drain pro if it’s only your home; Pennsylvania American Water if the street is affected |
| Spring Garden, Springettsbury, West Manchester, Manchester and York townships; North York and West York boroughs | Your township or borough collects sewage; it is treated at the York plant | A drain pro, or your township/borough if neighbors are affected |
| Hanover, Red Lion, Dallastown, Shrewsbury, Dover and other boroughs | Local borough or township authority | The number on your sewer bill if the main is suspected |
| Rural homes on septic | You own the whole system | A septic company if the tank is full; a drain pro if the line to the tank is blocked |
Snake, hydro jetting or camera: which does a York County home need?
| Method | Best for | Watch out for | Ask the pro |
|---|---|---|---|
| Drain snake / cable machine | Hair, soap, paper and most single clogs; cutting through roots | Roots grow back if the pipe is cracked | How far did the cable go, and what came back on it? |
| Hydro jetting | Grease, scale and root regrowth in sound pipe | Can worsen cracked clay, Orangeburg or thin cast iron | Will you camera the line before jetting? |
| Sewer camera inspection | Repeat clogs, older laterals, home purchases, sunken yards | Doesn’t clear anything on its own | Can I see the video and the footage of any defects? |
| Spot repair or trenchless lining | Broken, offset or root-filled sections found on camera | Not every line qualifies for lining | What did the camera show, and where? |
How much does drain cleaning cost in York County?
There is no honest flat price, because the job changes with the pipe. The pro confirms the price on the call or on site before any work starts. These are the factors that move it:
| Factor | Why it matters |
|---|---|
| Access | A clean, reachable outdoor or basement cleanout is faster than pulling a toilet or working through a roof vent. |
| Line length and depth | Longer laterals to the street take more cable and time. |
| What’s in the pipe | Roots and scale take longer than a soft paper clog. |
| Camera inspection | Adds time but shows whether the line is damaged. |
| Time of the visit | Night, weekend and holiday visits often cost more than weekday daytime. |

York County Drain Cleaning FAQ
Will Drano or another chemical cleaner clear a main sewer line?
No. Chemical cleaners are made for small hair or soap clogs near the drain opening. They cannot cut tree roots or reach a blockage 40 to 80 feet out in the lateral, and in older York County homes the heat can damage cast iron and PVC joints. If several drains are backing up, stop using water and call for a cable or jetting clean.
Does homeowners insurance cover a sewer backup in Pennsylvania?
Usually not on a standard policy. Sewer and drain backup is normally a separate endorsement (rider) you add to your homeowners policy, and flood insurance is a different policy again. Check your declarations page for “water backup” or “sewer backup” coverage before storm season.
Can the city or sewer authority be responsible for a backup in my house?
Sometimes. If the blockage was in the public main and the sewer operator knew or should have known about it, they may be liable. Claim windows can be short. Photograph everything, report it to the provider on your sewer bill the same day, and call your insurer. This is general information, not legal advice.
How often should a sewer line be cleaned in an older York home?
There is no single schedule. Homes with known root intrusion in clay or cast-iron laterals often need maintenance cleaning every 12 to 24 months, while newer PVC lines may go years without trouble. A camera inspection after the first cleaning shows which group your home is in.
Is hydro jetting safe for old clay or cast-iron pipes?
Usually, if the pipe is structurally sound. Jetting can make cracked clay, collapsed Orangeburg or badly scaled cast iron worse, so a good tech runs a camera first and chooses cable cleaning for fragile sections.
What if my drain backs up at night or on a weekend?
Stop using water, keep kids and pets away from any sewage, and call (888) 703-1520. We try to connect you with the next available local pro. After-hours availability varies and weekday daytime calls connect fastest, so say first if sewage is actively coming up.
