Commercial Plumbing in Bethlehem: Kitchen Drains, After-Hours Leaks and Rental Buildings
A plumbing failure in a business or a rental building costs money by the hour. A backed-up kitchen line closes a restaurant. A burst pipe in an apartment building can reach three floors.
Commercial and multifamily calls go to the same dispatch number as residential ones. Work goes to a plumber in our network, and the scope here is small commercial, restaurants and apartment buildings.

Which properties this page covers
The service is built for small commercial properties: restaurants and cafes, shops and offices, and apartment or mixed-use buildings. Larger industrial plants, high-rise systems and cold-storage work are outside what this line takes.
- Restaurants and commercial kitchens: grease, floor drains, hand sinks and water heaters.
- Shops and offices: restrooms, leaks, water heaters and drain clogs.
- Apartment buildings and mixed-use buildings: shared stacks, leaks that reach other units and hot water for several households.
- Landlords and property managers who need a plumber after hours.
Commercial and multifamily calls are answered on the same number as residential service, day or night. Backflow testing and certification is not part of this service.
Confirmed by the dispatch operator, 2026-10-30.
Emergency calls for these properties go to the same line, day or night.
Owners who see the same problem repeat often ask about scheduled maintenance. Whether an agreement is available is a question for the plumber who serves your building, and dispatch will route the call.
Restaurants: grease, floor drains and hot water
Kitchen lines carry grease, food solids and hot water, so they clog and slow down faster than a house drain. The problems repeat unless the cause is dealt with, not just the symptom.
| Problem | Usual cause | What the plumber checks |
|---|---|---|
| Floor drain backs up during service | Grease and solids in the line | Clear the line, then camera it for damage |
| Slow prep sink or hand sink | Partial blockage or a clogged trap | Trap, branch line and venting |
| Water heater cannot keep up | Demand above the unit's capacity | Size, recovery and the booster, if any |
| Grease smell from drains | Buildup in the trap or the line | Trap, drain and cleaning schedule |
Ask the plumber about a cleaning schedule for the drains and the grease trap if your building has one. A recurring problem needs a plan, not a repeat call.

After-hours leaks: who to call first
In a commercial building the first call depends on the building. Tenants usually call the owner or manager. Owners and managers call dispatch.
- Shut off the water to the affected area, or the main, if you can reach it.
- Move stock, records and equipment away from the water if it is safe.
- Notify the owner or manager and any tenants below the leak.
- Call dispatch and say which floor, which unit and what is leaking.
- Photograph the damage for the insurance file.
If water has spread, the flood cleanup page covers the dry-out. A hidden leak in a shared wall may need hidden leak detection.
Leave a note on the door of the affected room so no one switches on equipment that has been wet.
Landlords, tenants and property managers
Rentals make up a large share of the housing here, which means plumbing calls come from tenants, owners and property managers alike. Who pays depends on the lease and on what failed.
The City's owner-occupied housing rate is 50.7 percent. Tenants should report problems to the landlord first, and owners should keep a written record of each call and repair.
Census QuickFacts figure for Bethlehem city (ACS 2019 to 2023), read 2026-10-30.
- Owners: name one contact for after-hours calls and share it with tenants.
- Tenants: report the problem in writing and keep a copy.
- Managers: ask the plumber for a written summary of the cause and the repair.
A written log of each report and repair is the record most owners lean on later.
Drains, heaters and leaks in a larger building
Most commercial calls are versions of the same jobs that homes need, but at a larger scale. A shared drain backs up into the lowest unit. A water heater serves several tenants. A leak in a stack soaks the units below.
- Mainline and floor drain cleaning: see the drain cleaning overview.
- Camera inspection and sewer repair: see the sewer repair page.
- Water heater service for a shared system: see the no hot water guide.
- Slab, pipe and burst-pipe repair in a small commercial building.
In a building with several tenants, ask the plumber to note which units share the line that was cleared or repaired. That note tells the owner whom to contact if the problem returns.
Permits, sewer charges and what this line does not cover
The City of Bethlehem bills sewer service to commercial, industrial, institutional and public customers under a separate rate class, so a business owner should expect a different charge from a household. Ask the City which class your property falls under.
Permits for commercial plumbing are handled by the municipality that serves the address. Confirm with the permit office before work starts. Backflow testing and certification is not part of this service, so ask the municipality for a certified tester.
For work that changes pipes inside a restaurant or an apartment, ask the municipality whether plans or inspections are needed before the work starts, and ask your plumber to say who handles each step.
Keep the written scope, the permit paperwork and the plumber's notes together in one folder for the property.
Commercial plumbing questions answered
Do you take commercial plumbing calls on the same number?
Yes. Commercial and multifamily calls are answered on the same dispatch number as residential service, at any hour. The dispatcher asks about the address, the type of building and what is happening, then hands the job to a plumber in our network.
What kinds of businesses do you cover?
Small commercial: restaurants and cafes, shops, offices and apartment or mixed-use buildings. Industrial plants and large systems are outside the scope of this line. Tell the dispatcher the type of building when you call.
Do you do backflow testing?
No. Backflow testing and certification is not part of this service. Ask the municipality that serves your address for a certified tester.
Who pays for a plumbing repair in a rental building, the landlord or the tenant?
It depends on the lease and on what failed. Tenants should report problems to the landlord in writing. Owners and managers should keep a record of each call and repair. Dispatch can take the call from either.
Can a restaurant get help with a grease-clogged drain at night?
Yes. Dispatch runs every day of the year. Tell the dispatcher it is a kitchen drain and whether the floor drain is backing up, so the plumber who arrives has suitable equipment.
