Essential Plumbing Checks When Buying a Home

Buying a home is one of the most significant investments you’ll make, and ensuring the property’s plumbing is in good condition is a critical step in the process. A thorough plumbing inspection can save you from unexpected repairs and expenses down the road. Here’s a detailed guide to what to look for when inspecting a home’s plumbing system before finalizing your purchase.

Locate and Test the Main Water Shut-Off Valve

The main water shut-off valve controls the water supply to the entire house. Locate it, typically in the basement, crawl space, or near the water meter, and ensure it’s functional. A stuck or broken valve can complicate emergencies and lead to unnecessary damage. Turn the valve on and off to confirm it’s working correctly and isn’t seized. If you’re unsure how to test it, consider having a plumber inspect it for you.

Inspect Visible Pipes for Damage

Check exposed pipes in the basement, utility room, or crawl space for signs of rust, corrosion, or leaks. Look for discoloration or moisture around pipe joints, as these can indicate existing or potential issues. Additionally, listen for unusual sounds, such as banging or clanging, when water flows through the pipes, as this may suggest loose fittings or water hammer issues.

Assess Water Pressure

Low or inconsistent water pressure can indicate underlying plumbing problems. Test the water pressure at various faucets throughout the home. Ideally, water pressure should range between 40-60 psi. Pressure that’s too high can stress pipes and fixtures, while low pressure may point to blockages or leaks. High pressure may require the installation of a pressure-reducing valve, and low pressure could indicate issues with the municipal supply or internal plumbing.

Check for Signs of Leaks

Examine under sinks, around toilets, and behind appliances like dishwashers and washing machines. Look for water stains, warped cabinetry, or mold, which can indicate past or present leaks. Don’t forget to check ceilings and walls for water damage. If you notice a musty smell or peeling paint, these could be signs of hidden leaks requiring immediate attention.

Inspect the Water Heater

A functional water heater is essential for any home. Check the unit for rust, leaks, or unusual noises. Verify its age and capacity—most water heaters last 8-12 years. Also, ensure the temperature is set to a safe level (typically 49°C or 120°F). Additionally, ask whether the water heater has been flushed annually to remove sediment buildup. Check the anode rod—a component that prevents tank corrosion—and ensure it’s not worn out.

Evaluate Drains and Toilets

Run water through all sinks, tubs, and showers to check for slow draining, gurgling sounds, or odors, which can signal blockages. Flush each toilet to ensure they empty and refill correctly. Check for rocking or leaks at the base of toilets. Be attentive to water pooling around the drains, as this may indicate improper installation or pipe slope issues.

Inspect the Sewer and Septic Systems

If the home is connected to a sewer system, locate the sewer clean-out and ask about any history of backups. For homes with a septic system, request maintenance records and verify the last time it was pumped. A professional inspection of these systems is highly recommended. Inquire whether the sewer line has been inspected for tree root intrusion or other blockages that can lead to costly repairs.

Examine Outdoor Plumbing

Don’t overlook outdoor faucets, irrigation systems, and drainage. Test outdoor spigots for water flow and leaks. If the home has a sprinkler system, ensure it’s operational and free of damage. Proper drainage around the property is also crucial to prevent water pooling near the foundation. Check downspouts and gutters to ensure they direct water away from the home.

Consider the Age of the Plumbing System

Older homes may have outdated plumbing materials, such as galvanized steel or polybutylene, which are prone to corrosion and failure. Consult with a plumber to assess the longevity and safety of the system. Replacing old pipes can be a significant expense. If the home has copper piping, ensure it’s in good condition and free from signs of pinhole leaks or corrosion.

Check for Compliance with Local Codes

Ensure the plumbing system complies with local building codes. Non-compliance can lead to fines or necessitate costly upgrades. A professional plumber or home inspector can verify this for you. Verify that any renovations or additions made to the home have proper permits and meet current standards.

Test for Water Quality

Poor water quality can affect your health and appliances. Consider testing the water for contaminants, hardness, and pH levels. If issues are found, a water filtration or softening system may be needed. Additionally, check for unusual odors or discoloration in the water, which may indicate problems with the water source or internal plumbing.

Conclusion

A detailed plumbing inspection can provide peace of mind and help you make an informed decision when buying a home. By addressing potential issues early, you’ll be better prepared to negotiate repairs or budget for future upgrades. For expert advice or assistance, consult a licensed plumber who can guide you through the process.
