Most of us don’t think about our home’s plumbing until something goes wrong. A sudden leak, a clogged drain, or an ice-cold shower can instantly disrupt our lives and lead to costly, stressful repairs. But what if you could get ahead of these problems?
Just like a regular check-up at the doctor, a routine professional plumbing inspection is one of the most powerful preventative measures you can take for your home. It’s about shifting from a reactive “fix-it-when-it-breaks” mindset to a proactive one that saves you money, conserves water, and gives you invaluable peace of mind.
But what exactly should a thorough inspection cover? To help you understand the value of this service, we’ve put together this comprehensive plumbing inspection checklist for Los Angeles homeowners. This is what a true professional should be looking at to ensure your system is in top shape.
The Ultimate Plumbing Inspection Checklist
A comprehensive inspection goes far beyond just looking for drips. A licensed plumber uses their expertise to assess the health of your entire plumbing system, from where the water enters your home to where it leaves. Here’s what a detailed inspection should always include:
1. A Thorough Leak and Corrosion Check
This is the foundation of any good inspection. Undetected leaks are a leading cause of catastrophic water damage and toxic mold growth.
- Visible Pipe Inspection: The plumber should visually inspect all exposed pipes in your home—under sinks, in the basement or crawl space, and in the utility room—for any signs of moisture, rust, or corrosion. Greenish-blue stains on copper pipes or rust spots on galvanized steel are early warnings of degradation.
- Fixture and Appliance Check: They will examine all fixtures, including faucets, showerheads, and toilets, for drips and leaks. This also includes checking the supply lines and hoses connected to your washing machine, dishwasher, and refrigerator icemaker for cracks or bulges, as these are common failure points.
- Water Meter Test: To check for hidden leaks behind walls or under floors, a plumber can perform a water meter test. By turning off all water-using appliances and watching the meter, they can determine if water is still flowing somewhere in the system—a clear sign of a hidden leak.
2. Comprehensive Water Heater Assessment
Your water heater is a complex and vital appliance. A proper inspection is crucial for safety, efficiency, and longevity.
- Safety Valve Test: The Temperature and Pressure (T&P) relief valve is a critical safety component designed to release pressure if the tank overheats. A plumber will test this valve to ensure it functions correctly, preventing a potential explosion risk.
- Anode Rod Check: The “sacrificial” anode rod protects your tank from rusting from the inside out. A plumber should check its condition, as a depleted rod means your tank is no longer protected and is at high risk of failure.
- Sediment and Leak Inspection: They will look for signs of sediment buildup, which reduces efficiency, and carefully inspect the tank and its connections for any signs of leaks or corrosion. A leaking tank is an emergency that signals imminent failure.
3. Drain and Sewer Line Evaluation
Slow or clogged drains are more than just an annoyance; they can be a symptom of a serious blockage in your main sewer line.
- Drain Flow Test: The plumber will test every drain in your home—sinks, tubs, and showers—to ensure they are draining quickly and freely. Sluggish or gurgling drains are a sign of a developing clog.
- Video Camera Inspection (Recommended): For a truly comprehensive plumbing inspection checklist in Los Angeles, a video camera inspection is invaluable. A plumber can feed a flexible, waterproof camera down your main sewer line to get a real-time look at its condition. This allows them to identify tree root intrusion, cracks, collapsed sections, or severe blockages before they cause a disastrous sewer backup.
4. Water Pressure Analysis
Water pressure is a delicate balance. Too low, and it’s a nuisance; too high, and it can destroy your entire plumbing system.
- Pressure Test: Using a pressure gauge, the plumber will test the water pressure at an outdoor spigot. Ideal pressure for a residential home in Los Angeles is typically between 50 and 70 PSI.
- Pressure Regulator Check: If pressure is too high (above 80 PSI), it puts immense stress on your pipes, joints, and appliances, leading to leaks and premature failures. The plumber will check if you have a water pressure regulator and ensure it is functioning correctly. If you don’t have one, they should recommend installing one to protect your plumbing system.
5. Shut-Off Valve and Outdoor Fixture Check
In an emergency, you need to be able to shut off your water supply quickly. Valves that are “frozen” in place can turn a small problem into a major disaster.
- Main Shut-Off Valve Test: The plumber will locate and test your home’s main water shut-off valve to ensure it operates smoothly and isn’t seized from corrosion.
- Individual Valve Test: They will also test the individual shut-off valves (stop valves) for each toilet and sink to confirm they are functional.
- Outdoor Faucet Inspection: Hose bibs (outdoor spigots) will be checked for leaks and proper function to prevent water waste and potential damage.
