Southern California is home to countless historic and mid-century commercial buildings, many of which have stood the test of time. But while the design and appeal of these structures often remain, their plumbing systems can tell a different story. Aging infrastructure combined with decades of wear and tear can lead to a host of plumbing issues that affect operations, safety, and even compliance.
In this article, we explore the most common plumbing problems in older SoCal commercial properties and how proactive maintenance and upgrades can prevent costly disruptions.
Seven Common Issues
1. Corroded Pipes
One of the most widespread issues in aging commercial buildings is pipe corrosion. Many structures built before the 1970s used galvanized steel or cast-iron pipes, which are prone to rust and deterioration over time. This can result in:
- Reduced water pressure.
- Discolored water.
- Leaks and eventual pipe failure.
In areas with hard water common in parts of SoCal corrosion happens even faster due to mineral buildup. Pipe replacement or lining may be necessary for long-term reliability.
2. Sewer Line Damage
Old sewer lines made of clay, cast iron, or Orangeburg (a bituminous fiber pipe) are especially vulnerable to root intrusion and collapse. Signs of sewer line trouble include:
- Frequent drain clogs.
- Sewage odors in or around the building.
- Backups or standing water outside.
Trenchless sewer repair options, such as pipe bursting or relining, can offer less disruptive solutions for commercial properties.
3. Outdated Fixtures and Water Waste
Leaky toilets, inefficient faucets, and old water heaters not only affect performance but can also waste thousands of gallons of water annually. For commercial buildings under strict utility budgets or sustainability mandates, outdated fixtures are a liability. Upgrading to low-flow and sensor-based systems can significantly reduce water usage and costs.
4. Hidden Leaks and Water Damage
In older buildings, plumbing leaks may go unnoticed behind walls or under floors until mold, mildew, or structural damage appears. Over time, even small leaks can compromise drywall, flooring, and insulation. Regular plumbing inspections using moisture sensors or thermal imaging can help detect hidden issues early.
5. Clogged or Damaged Drains
Years of grease, soap scum, food debris, and sediment can lead to frequent drain clogs, particularly in commercial kitchens or restrooms. In older pipes with rough interior surfaces, buildup is more common. Hydro-jetting is an effective method for thoroughly cleaning out drain lines and restoring proper flow.
6. Inefficient or Overloaded Water Heaters
Old commercial water heaters often struggle to meet the demands of modern-day usage. Whether it is a restaurant, office, or apartment building, an underperforming water heater can cause complaints and delays. Sediment buildup at the bottom of tanks can also reduce heating efficiency and shorten equipment life.
7. Non-Compliant or Unsafe Plumbing Installations
Plumbing codes evolve over time. Older buildings may not meet current health and safety standards, especially if modifications were made without proper permits. Issues such as missing backflow preventers or non-compliant drain slopes can create health hazards or lead to fines. A professional plumbing audit ensures your system complies with current regulations.
Older commercial buildings across Southern California carry a unique appeal but their plumbing systems require special attention. Whether it is corroded pipes, outdated fixtures, or hidden leaks, early detection and timely upgrades are key to preventing major disruptions and costly repairs.
If you are a property manager or own an older commercial property, regular plumbing inspections are essential. Partner with a licensed plumbing professional familiar with SoCal infrastructure to extend the life of your building and ensure reliable, efficient operation.
