On June 6, 2020 a hot water pipe was spraying under a kitchen. The California Court of Appeal did not award the claim. On May 14, 2026 it said a jury could find the release was sudden. October 13, 2026.

The polybutylene settlement is closed. The pipe is still in the wall.

Cox v. Shell paid to replumb more than 300,000 homes. The claim window closed in 2009. A repair of one fitting leaves the rest of that system in the house. October 13, 2026.

CSLB fines for unlicensed work start at $1,500.

The new floor took effect July 1, 2026. Hiring an unlicensed person for licensed plumbing work can be discipline for the shop. Home improvement contracts picked up two rules on January 1. October 13, 2026.
