Water pressure problems can manifest as either too high or too low water pressure. Low water pressure could indicate a blockage or leak somewhere in the system, while high water pressure can lead to leaks and damage to your appliances. It’s crucial to check water pressure during the inspection to ensure it is within the acceptable range.


Tips for Writing Detailed Inspection Reports

Writing detailed inspection reports is a crucial aspect of the plumbing inspection process. It allows property owners to understand the current state of their plumbing system, prioritize necessary repairs, and maintain their system appropriately. Here are some tips for writing detailed and effective inspection reports.\

Record Findings Accurately

Accurate documentation of your findings during the inspection is paramount. Describe the issues you’ve discovered in a clear, concise manner. Mention the location of the problem and provide as much detail as possible about the nature and extent of it. For instance, instead of just noting “leak in the bathroom,” you could write “minor leak under the sink in the upstairs bathroom, likely due to a worn seal.”

Include Photographs

Photographs provide a visual reference that supports your written findings. They illustrate the exact location and severity of a problem, making it easier for others to understand. Take clear photos before, during, and after any repair work for a complete record.

Prioritize Repairs

Not all plumbing issues require immediate attention. Prioritize the problems found based on their severity and potential to cause further damage. This helps the property owner plan and budget for repairs. For example, a leaking pipe that could cause water damage to the building structure should be prioritized over a dripping faucet.

Recommend Maintenance

A good inspection report should note current problems and include maintenance recommendations to prevent future issues. This could involve suggesting regular drain cleaning to avoid clogs or advising on replacing old pipes that are more likely to leak. Your expertise in this area provides valuable guidance and can help prolong the life of the plumbing system.
