A clogged manhole is a problem that affects a property’s entire sewer system—and is often the root cause of recurring clogs that never seem to be resolved once and for all. The Canalizador de Lisboa provides manhole cleaning services in Lisbon using professional equipment and experienced technicians.

What is a visitor box?

A manhole is an inspection chamber that collects various sewer branches before they connect to the public sewer system. It is usually located outside the property—on the sidewalk, in the yard, or in the basement. When it becomes clogged, all of the building’s sewers are affected.

Signs of a Clogged Sink Drain

  • Simultaneous clogs at various locations throughout the property
  • Backflow of wastewater in floor drains and toilets
  • A strong, foul odor coming from outside or the basement
  • Water accumulating near the outdoor utility box
  • Recurring clogs that cannot be resolved by internal drain cleaning
