Northampton Plumbing: Slow Drains, Wet Ceilings and Who Handles the Sewer
Northampton is about 7.6 miles from Bethlehem, in Northampton County.
Along Laubach Avenue stand the borough administration office at number 1401 and Northampton Area High School at number 1619, and plumbing questions in town tend to start with the office. This page covers the borough of Northampton, ZIP 18067, in Northampton County. It is not Northampton Township in Bucks County.
A sink that will not drain, a stain spreading across a ceiling and a basement floor drain that bubbles are the usual first calls. Tell the dispatcher what you see and your street, and a network plumber who covers the borough takes the job.

Slow drains and backups in Northampton: what the symptom points to
Where the water backs up tells you how far down the line the trouble sits. The plumber starts from your description, so give it precisely.
- A single sink or tub that drains slowly: the clog is in that fixture or its short branch.
- The lowest drain in the house gurgles when upstairs fixtures run: air is being pushed ahead of a blockage in the main.
- A floor drain that rises: the main line is blocked or full, and nothing should be flushed until it is cleared.
- A fixture that clogs again soon after being cleaned: have the plumber put a camera in the line.
Cable, jetting and camera work are compared on the drain clearing guide. Stop using water if sewage is rising.

Toilet and faucet trouble in Northampton
A toilet that hisses after a flush or a faucet that weeps at the base wastes water and rarely fixes itself. Name the fixture and describe its symptom when you call. The faucet repair guide shows how a plumber narrows down the part.
If the fixture is in a rental, report it to the owner in writing and keep a copy.

Slab floors and basements in Northampton
We found no sourced figure for the age of homes or the foundation type in the borough, so we make no claim about either. If a floor feels warm in one spot, or you hear water with every tap off, mention it to the plumber. The slab leak overview explains how a plumber finds a leak under concrete.
Public sewer and water in Northampton
Inside the borough, the sources we read point to public service: the borough owns the sewer, and the Northampton Borough Municipal Authority supplies water. We found no count of houses on private systems, so we claim no share.
If your house is outside the borough, the arrangement may differ. Cementon, for instance, is in Whitehall Township, where sewer service comes from the Coplay-Whitehall Sewer Authority. Tell the dispatcher your street and whether the house uses public sewer and public water, so the right plumber is sent.
Water damage after a leak or backup in Northampton

Northampton homeowner questions
Is a Northampton house on public sewer and water, or on its own system?
Within town limits, the sources we read show a borough-owned sewer and a water system run by the Northampton Borough Municipal Authority. We found no count of houses on private systems. Outside the borough, for example in Cementon, the arrangement can differ, so tell the dispatcher what your house uses.
Does Northampton require a permit for plumbing work?
The borough code calls for a certificate of approval for plumbing work, administered through the Office of Code Enforcement, but it is an older codification and may have been updated. We found nothing specific on water heaters or laterals, so ask the code office and ask your plumber who files.
