10 Plumbing Inspection Tips for Your Renovation Checklist

Renovating your home is an exciting yet daunting process, especially when it involves plumbing. Whether you're renovating a kitchen, bathroom, or entire home, ensuring that your plumbing system is in good working order is critical to preventing future problems and costly repairs. A thorough plumbing inspection can identify hidden issues, ensuring that your renovation runs smoothly and efficiently. Here are ten essential plumbing inspection tips to add to your renovation checklist.

Check for Leaks

Leaks are one of the most common plumbing problems that can go unnoticed during renovations. Even minor leaks can lead to significant water damage, mold growth, and increased water bills. Before starting your renovation, inspect the entire plumbing system for leaks, particularly in areas that are hard to reach, such as behind walls or under floors.

How to Check for Leaks:

• Turn off all water appliances: Shut off water sources like faucets, dishwashers, and washing machines, and check the water meter. If the meter continues to run, there's likely a hidden leak.
• Look for damp spots: Examine walls, ceilings, and floors for any signs of moisture or water stains.
• Test pipe joints: Check the joints and connections in exposed pipes for any signs of leakage, especially around fittings, valves, and seals.

Inspect Pipe Material and Age

The age and material of your pipes are crucial factors in determining whether they are in good condition or if they need replacing. Older homes may still have lead, galvanized steel, or polybutylene pipes, all of which are prone to corrosion, leaks, and health concerns.

What to Look For:

• Lead pipes: If your home still has lead pipes, they should be replaced immediately as lead exposure can cause serious health problems.
• Galvanized steel pipes: These pipes are prone to rust and corrosion and may need to be replaced if they are more than 50 years old.
• Polybutylene pipes: These are plastic pipes that were commonly used in homes built from the 1970s to the 1990s. They are known to break down over time and are no longer recommended for use.

If you're unsure about the materials used in your plumbing system, consult a professional plumber to conduct a comprehensive inspection.

Examine Water Pressure

Water pressure is an important factor in ensuring that your plumbing system operates efficiently. Low water pressure can indicate an underlying issue, such as a clogged pipe, a leak, or sediment build-up in the pipes.

How to Check Water Pressure:

• Test faucets: Turn on the faucets in your kitchen, bathrooms, and laundry rooms and observe the water flow. A slow or weak stream may indicate low pressure.
• Use a pressure gauge: You can purchase a water pressure gauge to check the pressure at any faucet or outdoor spigot. Ideal water pressure ranges from 40 to 60 psi (pounds per square inch). Anything below this could require an adjustment.
• Check for high pressure: Conversely, excessively high water pressure (above 80 psi) can put strain on pipes and cause leaks. You can install a pressure regulator to manage this if needed.

Test for Proper Drainage

Poor drainage can be a significant problem during renovations, especially in areas like bathrooms and kitchens. If your drains are slow or clogged, it may indicate blockages or damage in your plumbing system.

How to Test Drainage:

• Check drains: Turn on the water in all sinks, bathtubs, and showers, and watch for any slow drainage or standing water.
• Look for gurgling sounds: Gurgling noises from drains may indicate air trapped in the pipes or a partial blockage.
• Flush toilets: Test all toilets in the home to ensure they flush properly and drain quickly without any issues.

If you notice any drainage issues, consult a plumber to clear blockages or inspect for damaged pipes.

Inspect Ventilation Systems

Proper ventilation is essential for your plumbing system to function properly. Without adequate venting, water and wastewater may struggle to flow smoothly through the pipes, leading to slow drainage, foul odors, and gurgling noises.

How to Check Ventilation:

• Inspect vent pipes: Ensure that vent pipes are unobstructed and free of debris. These pipes allow air to enter the plumbing system and ensure that water flows smoothly through the pipes.
• Check for odors: Foul odors in drains may indicate that ventilation is not working properly or that wastewater is stagnating in the pipes.

If you suspect a venting problem, it's important to have it addressed before proceeding with your renovation.

Evaluate the Condition of Sewer Lines

Sewer line issues can be difficult to detect, but they can cause major problems during your renovation if not addressed early on. A blocked or damaged sewer line can lead to sewage backups, unpleasant odors, and health risks.

How to Inspect Sewer Lines:

• Look for signs of leaks: Check around the base of toilets, floor drains, and other sewer connection points for any signs of leaks or water stains.
• Check the yard: If your home has a septic tank or external sewer line, look for areas of your yard where the ground is unusually wet or where there's an odor, which may indicate a sewer leak.
• Consider a professional inspection: If you're concerned about the condition of your sewer lines, a plumber can use a camera inspection to examine the interior of your pipes and identify any blockages, cracks, or other issues.

Ensure Proper Hot Water Functionality

If you're planning a renovation that involves a kitchen or bathroom remodel, it's essential to verify that your hot water system is in good working condition. This is especially true if you are replacing or installing new fixtures like showers or dishwashers.

How to Inspect Your Water Heater:

• Check the age of your water heater: Most water heaters last between 8 and 12 years. If your unit is nearing the end of its life, consider replacing it before you begin your renovation.
• Test water temperature: Run the hot water in various taps to ensure that it heats up quickly and maintains a consistent temperature.
• Inspect for leaks: Check around the base of the water heater for any signs of leaks or pooling water, which may indicate a problem with the unit or connections.

If your water heater is outdated or malfunctioning, it's a good idea to replace it before your renovation progresses.

Check for Mold or Mildew

Mold and mildew are common issues in areas with high humidity, such as bathrooms, kitchens, and basements. If left untreated, mold can damage your plumbing system and negatively affect your health.

How to Inspect for Mold:

• Look for visible mold: Check around plumbing fixtures, under sinks, and in damp areas of your home for visible signs of mold or mildew.
• Check for musty odors: A musty smell is often a sign of hidden mold. Inspect areas that may have had water exposure but are not easily visible, such as behind walls or under floors.
• Check ventilation: Poor ventilation is a major factor in the growth of mold. Ensure that exhaust fans are working and that there's adequate airflow in areas prone to moisture.

If you find mold, it's important to address it quickly by cleaning the area and repairing any water damage.

Check for Proper Insulation

Proper insulation around your pipes is essential, especially in regions that experience freezing temperatures. Frozen pipes can crack or burst, leading to water damage and expensive repairs. Inspect your pipes to ensure that they are properly insulated, especially in unheated areas like attics, basements, and crawl spaces.

How to Inspect Insulation:

• Look for exposed pipes: Check for any pipes that are not insulated or are poorly insulated. Focus on pipes in unheated or cold areas.
• Inspect insulation material: Ensure that the insulation is intact and in good condition. If you see any signs of wear or damage, replace the insulation immediately.
• Check for freezing risk: During colder months, keep an eye on the temperature in areas where pipes are located to prevent them from freezing.

If you're unsure about how to properly insulate your pipes, consult a professional plumber to ensure that your plumbing system is prepared for the colder months.

Hire a Professional Plumber for a Comprehensive Inspection

While DIY inspections can help you catch common plumbing issues, hiring a professional plumber is the best way to ensure that your plumbing system is in good condition before you start your renovation. A licensed plumber can perform a thorough inspection, including checking for hidden leaks, testing water pressure, and using advanced tools like cameras to examine sewer lines and pipes.

Why Hire a Professional?

• Expert knowledge: Plumbers have the expertise to identify hidden issues that may be overlooked by the untrained eye.
• Specialized tools: Professional plumbers have access to advanced tools and technology that can detect issues inside your pipes and sewer lines.
• Peace of mind: Knowing that your plumbing system has been thoroughly inspected will give you confidence as you proceed with your renovation.
