Who to call first depends on your role
If you rent
Report the problem to your landlord or property manager first, in writing if you can. Your lease decides who arranges and pays for repairs.
If you own a unit
Check whether the pipe serves only your unit. Lines inside shared walls are often an association matter. Read your declaration.
If you manage or own the building
Document the complaint, shut off the affected branch and bring in a plumber who will describe the problem in writing.
We are not a substitute for your lease or a lawyer. Whatever the arrangement, shutting off water to stop damage is usually a safe first move, and it should be reported to whoever manages the building.

Sewer and water rules in Horsham
Horsham Water and Sewer Authority's published rules make the customer responsible for the building lateral and the Authority for the service lateral out to the right-of-way. In a multi-unit property, the building owner holds that responsibility, not an individual tenant.
If a whole building has a backup, the Authority will check its street main at no charge when you call (215) 672-8011. The Authority also says most basic homeowner policies do not cover sewer backups, so owners and managers should read their own coverage. Tenants may want renter's insurance that covers belongings.
A simple shutoff routine
- 1
Find the fixture valve
Toilets and sinks have small valves on the wall or floor. Turn clockwise to stop the water at that fixture.
- 2
Find the unit shutoff
Many apartments have a shutoff in a utility closet or near the water heater. Ask the manager where it is before you need it.
- 3
Report it
Tell your landlord or manager what you shut off and why, and keep photos.
