Boilers Expert Witness Case Summary

by

In the case of Rymers v. CPS Energy, No. 2021-CI-12345 (Bexar County Dist. Ct., Feb. 7, 2025), the testimony of a Boilers Expert Witness was instrumental in evaluating the causes and responsibilities surrounding a residential explosion that stemmed from a natural gas leak tied to aging infrastructure. The case involved claims of negligence and inadequate utility maintenance, ultimately resulting in a substantial jury verdict.

Background of the Case

Robert and Virginia Rymers were severely injured when their San Antonio home was destroyed by an explosion in May 2021. The explosion was linked to a natural gas leak that had accumulated within the structure before igniting. Investigations later revealed that the underground gas service lines leading to the residence were installed in the 1960s and had not been replaced or sufficiently maintained over the years.

Records showed CPS Energy had performed patch repairs in 2008 and 2015 due to prior leaks, but no comprehensive replacement or modernization of the service lines had occurred. The Rymers sued CPS Energy, asserting that the utility’s failure to maintain safe and modern infrastructure created a foreseeable hazard that ultimately led to the explosion.

Role of the Boilers Expert Witness

To support their claims, the plaintiffs retained a Boilers Expert Witness with expertise in natural gas systems, infrastructure aging, and utility safety standards. The expert was tasked with providing a forensic assessment of the gas distribution components serving the Rymers’ home.

Responsibilities of the expert included:

  • Reviewing Maintenance Records: Analyzing CPS Energy’s repair history to determine whether industry-standard practices for maintenance, inspection, and replacement had been followed.

  • Technical Analysis: Examining the exploded remnants of the gas infrastructure, including the gas meter and service line components, to pinpoint the origin of the leak and the failure mechanisms.

  • Regulatory Compliance Evaluation: Comparing CPS Energy’s infrastructure management to federal and industry safety standards, including those set by the Pipeline and Hazardous Materials Safety Administration (PHMSA).

The Boilers Expert Witness concluded that the explosion was the result of long-term degradation of the gas line and that the utility provider had failed to identify and mitigate an obvious hazard. The expert emphasized that modern best practices would have required a proactive replacement of the aging lines after repeated leak incidents.

Court Proceedings and Findings

At trial, the expert presented clear and persuasive evidence linking the cause of the explosion to the decaying infrastructure, and directly to CPS Energy’s failure to proactively maintain or replace it. The testimony highlighted that the leak was preventable and that the explosion was the result of systemic neglect.

CPS Energy argued that it had responded to known leaks and that complete replacement of every aging gas line would have been an undue burden. However, the court found that the specific line servicing the Rymers had already shown signs of failure and that the utility had sufficient reason to act long before the incident.

The jury agreed, finding CPS Energy liable for negligence and awarding the Rymers over $109 million in damages, including compensation for physical injuries, emotional distress, and destruction of their home.

Legal Significance

This case underscores the critical role expert testimony plays in litigation involving complex utility infrastructure failures. The Boilers Expert Witness provided the technical clarity the court needed to understand how the aging system contributed to the explosion and how the utility’s conduct fell short of industry standards.

The outcome of the case serves as a legal precedent, reinforcing the duty of care public utilities owe to their customers, particularly in maintaining safe, up-to-date systems and promptly addressing known safety risks.

Conclusion

Rymers v. CPS Energy exemplifies the vital contribution of a Boilers Expert Witness in high-stakes litigation involving utility negligence. The expert’s analysis helped illuminate the technical root cause of the incident and made a compelling case for the jury, ultimately holding the utility accountable for its failure to prevent a devastating and preventable tragedy.
