Common questions
What should I do first if I see gurgling toilet and slow drains?
Reduce water use.
What should I do first during a plumbing emergency?
Stop the water source if safe, avoid using affected fixtures, protect people from contaminated water, and request help.

When is a sewer smell urgent?
Sewer smell is more urgent when it appears with slow drains, gurgling toilets, visible wastewater, or symptoms across multiple fixtures.
What should I avoid during a drain backup?
Avoid running more water, using chemical cleaners, running laundry or dishwasher cycles, and touching contaminated water.
