Drain & Waste Line Testing

Drain and waste leaks don't always show up as a dripping pipe — they show up as recurring stains, persistent musty odours, or water damage that doesn't track to a supply line. Our smoke and tracer-gas testing pressurizes the drain system with a harmless visible or chemical indicator that escapes through any failure point and can be located precisely on the surface. We do this for residential drain stacks, commercial waste systems, and below-grade lateral failures throughout Greater Vancouver. The deliverable is a single point of failure, not a list of possible causes.

Clients booking drain & waste line testing often combine it with Pressurized Line Detection or Slab Leak Location — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
