What is a reason to contact the inspector during installation?

Contacting the inspector during installation is crucial, especially when encountering significant issues such as hitting bedrock while trench digging. This situation is critical because bedrock can impede proper installation of the septic system, requiring adjustments to the system design or installation process. Notifying the inspector allows for immediate guidance on how to proceed, ensuring that the installation adheres to local regulations and maintains the system's integrity and functionality. The inspector may need to assess the situation on-site and provide direction on how to handle the bedrock in a way that complies with health and safety standards.

While relocating pipes or being ready to finish the installation are important milestones in the process, they do not necessarily require an inspector's immediate involvement. Likewise, not finding tools is typically a logistical issue that would not directly impact compliance or safety regulations, thus not warranting inspector intervention. It is the unforeseen challenges like encountering bedrock that necessitate contacting the inspector to ensure a compliant and effective installation.
