How we chose these

Same scoring engine as the main Oakland plumbing ranking, with an additional filter step: we look for Sewer & Main Line signals in each provider's business categories, service tags, and recent review text.

When the Sewer & Main Line filter would surface fewer than five providers, we fall back to showing top-rated plumbing pros generally - they are far more likely to handle sewer & main line work than an unrated provider would be.
