Whether you manage an apartment complex in Arcadia or oversee multiple properties across Southern California, this information will help you make informed decisions about your building’s sewer system maintenance.
Preparing for the Sewer Inspection
Proper preparation is the cornerstone of a successful sewer inspection for multi-unit buildings. At Western Rooter & Plumbing, we’ve learned that thorough planning helps avoid delays and ensures comprehensive results. Let’s walk through the essential preparation steps that property owners need to consider.
Gathering necessary documentation
Before scheduling your sewer inspection, you’ll need to compile several important documents. A complete documentation package helps ensure a smooth inspection process and compliance with local regulations. Here’s what you’ll need:
- Valid permits for any existing modifications
- Property insurance documentation
- Previous sewer inspection reports (if available)
- Building plans showing sewer line locations
- Backwater valve documentation
- Worker’s compensation insurance (if applicable)
The California Department of Housing and Community Development requires specific permits for various property modifications. Keep in mind that preliminary plan check meetings typically cost $238.00 per hour, with a one-hour minimum.
Notifying tenants and property management
Property owners must provide adequate notice to tenants before conducting a sewer inspection. California law requires a minimum 24-hour notice to tenants before entering their units. When scheduling the inspection, consider:
Your notification should clearly explain the purpose of the inspection, expected duration, and any preparations tenants need to make. It’s essential to coordinate with property management to ensure all affected units are properly notified and accessible on inspection day.
Clearing access points to sewer lines
Proper access to sewer lines is crucial for a thorough inspection. Sewer lines typically start 24 inches outside the foundation and should be installed at a minimum of 12 inches below grade. Before the inspection, ensure that:
The main cleanout should be located immediately outside the building, within 24 inches of the structure. For buildings from the 1950s and 1960s, cleanouts might not be readily visible, and roof access might be necessary. In such cases, we’ll need to bring additional equipment and crew members for safe access.
It’s important to verify electrical requirements in advance. Some inspection equipment requires access to power sources, so coordinate with property management to ensure availability. If needed, we can bring our own generator, but this should be arranged beforehand to avoid delays.
Choosing the Right Inspection Method
At Western Rooter & Plumbing, we understand that selecting the right inspection method is critical for accurately assessing your multi-unit building’s sewer system. With decades of experience serving the Greater Los Angeles area, we’ve mastered various inspection techniques to provide comprehensive solutions for our clients.
Camera inspection technology
Video inspection technology has revolutionized how we examine sewer systems in multi-unit buildings. Using high-quality digital cameras attached to flexible push rods, we can thoroughly inspect your pipes’ interior without any invasive procedures. Our camera systems reveal:
- Immediate structural problems
- Linear footage of pipes
- Branch connection locations
- Pipe diameter and material types
- Transitional changes in diameter
For complex systems, we employ different camera technologies based on your building’s specific needs. Our advanced lateral launch cameras can navigate through main lines and branch into secondary pipes, providing comprehensive coverage of your entire system. When dealing with particularly challenging layouts, our solo robotic crawlers can independently navigate and inspect designated areas while streaming live footage.
Smoke testing
Smoke testing is an efficient method for identifying leaks and unauthorized connections in your sewer system. This non-toxic procedure helps locate potential problems before they become major issues. The process involves introducing harmless smoke into the sewer system, which then reveals:
- Broken pipes or manholes
- Uncapped lines
- Storm drain cross-connections
- Foundation drain connections
- Roof drain tie-ins
Each smoke test typically takes 15-30 minutes per section, making it an efficient way to inspect larger properties. While residents don’t need to be present during testing, we recommend proper ventilation if smoke enters any units. Rest assured, the smoke we use is odorless, colorless, and completely safe.
Dye testing
For properties requiring detailed analysis of water flow patterns, dye testing provides invaluable insights. This method is particularly useful for verifying proper connections between storm water and sanitary systems. As your local plumbing experts in Arcadia and surrounding counties, we follow strict protocols for dye testing:
We use Norlab, Inc. liquid powder tracing dye, which is specifically approved for residential and commercial applications. The standard ratio is one ounce of dye per 250 gallons of water, adjusted based on water turbidity. This method helps us identify illicit connections and verify proper system operation.
When conducting dye tests, we carefully monitor downstream manholes to track the dye’s movement through your system. This allows us to accurately map connection points and identify any potential cross-contamination between storm and sanitary systems. For multi-unit buildings in our service area, this information is particularly valuable for maintaining compliance with local regulations.
Conducting the Sewer Inspection
When conducting sewer inspections in multi-unit buildings, having a systematic approach is essential for accurate results. At Western Rooter & Plumbing, we’ve developed a comprehensive process that ensures no detail goes unnoticed during our inspections across Los Angeles County.
Mapping the sewer system
The first crucial step in our inspection process involves creating a detailed map of your building’s sewer system. Using advanced LiDAR technology, we capture precise measurements and create comprehensive 3D point clouds of your entire system. This technology allows us to:
- Document exact pipe locations and depths
- Identify connection points between units
- Map drainage patterns and slopes
- Locate all access points and cleanouts
- Determine pipe materials and sizes
Our mobile scanning equipment lets us walk through your property while capturing every detail, ensuring nothing is missed. This detailed mapping becomes invaluable for future maintenance and helps us identify potential problem areas before they become serious issues.
Identifying common issues in multi-unit buildings
Multi-unit buildings present unique challenges when it comes to sewer systems. The interconnected nature of these systems means that problems in one unit can quickly affect others. During our inspections, we pay special attention to these critical areas:
