Slow drains, gurgling noises after a flush, and a foul odor drifting up from a floor drain usually point to grease or scale narrowing the pipe somewhere along the line. On older streets, a root pushing into a cracked joint causes the same symptoms. Vancouver's wet winters push a lot of runoff through storm drains and perimeter drains, and the clay or cast iron sewer laterals under many Metro Vancouver homes weren't built for the volume of water and waste moving through them today. Hydro jetting restores full flow capacity by breaking apart what's built up instead of carving a narrow channel through it.
Multi-family buildings and commercial kitchens across the Fraser Valley put grease traps through daily use, and fats, oils, and grease build up faster than most drain snakes can keep pace with. Mr. Rooter Plumbing of Vancouver BC pairs jetting with commercial plumbing service for grease-heavy kitchens, and follows up with trenchless sewer line repair when a section of pipe has already cracked instead of just clogged. A sewer camera inspection before and after the job means you see the water lines and drain tile are actually clear, not just quieter for a week.
