Plumbing for offices, plazas and retail units

A plaza unit with one broken washroom loses customers by lunch. An office with a running flush valve wastes water all night with nobody there to hear it.

  • Commercial flush valves, sensor faucets and wall-hung fixtures
  • Small commercial water heaters and mixing valves
  • Shared plaza drains traced to the unit that caused the backup
  • Rough-ins and fixture moves for tenant fit-outs
  • Licensed plumbers (details on request)
  • Written job sheet
  • Pressure-tested repairs
  • Homes and businesses

01Fixtures that take a beating

Public and staff washrooms see far more use than a home bathroom, and the parts are different:

  • Flushometer diaphragms and vacuum breakers that stick and run
  • Sensor faucets and flush valves with failing solenoids or batteries
  • Wall-hung toilets and urinals loosening on their carriers
  • Mop sinks and floor drains with dried-out traps letting sewer gas in
  • Mixing valves on hand sinks drifting too hot or too cold
Quick facts
Frequent callsRunning flushometers, blocked urinals, leaking wall carriers, cold staff sinks
Plaza quirkSeveral units often share one sanitary run to the street
Fit-out noteNew fixtures and moves generally need a building permit; check before the walls close

02Shared drains in strip plazas

Many Scarborough plazas were built with one sanitary line running behind the units. When it backs up, the lowest or last unit floods, even if the cause is a restaurant three doors up. We camera from the shared cleanout, find where the blockage sits and which branch is feeding it, then clear it. That information helps a landlord deal fairly with tenants and decide whether a grease interceptor or a scheduled cleaning is needed.

03Fit-outs and changes

A new tenant often wants a staff kitchen, an extra washroom or a sink moved. We look at where the drains and vents run before quoting the work, flag any permit needs and coordinate with the general contractor so the plumbing is roughed in and inspected before drywall goes up.
