Please call a plumber. Most sewer backups are service line related, which are not the responsibility of Southgate. If a plumber determines the backup is caused by a blockage in the main line, contact Southgate immediately.
If the property is not draining wastewater to the sewer system and wastewater continues to back-up into the structure or large quantities of wastewater (more than that produced by the property itself) continues to back-up into the structure, contact Southgate immediately at 303-779-0261.
