The DIY Plumbing Inspection Checklist

1. Check For Pipe Leaks

Start by inspecting exposed pipes under sinks and in basements or crawlspaces for any signs of pipe leaks. Leaks can often go unnoticed until they cause damage, so be sure to look for:

  • Water stains or dampness around joints
  • Cracked or corroded pipes
  • Puddles or drips

If you notice any of these signs, you must call a professional plumber to repair the leak before it worsens and causes further damage to your home.

2. Test Water Pressure

Low water pressure can indicate a pipe blockage or a bigger plumbing issue. Check water pressure in multiple areas of the house:

  • Open taps in the kitchen and bathroom.
  • Use a water pressure gauge if you have one or simply test the flow from taps and showers.

Low or inconsistent water pressure might indicate a pipe blockage or sediment buildup may affect your water heater. A professional plumbing inspection can help pinpoint the problem.

3. Inspect All Drains For Clogs

Slow-draining sinks, bathtubs, and showers are often the first signs of clogged drains. Here’s how to inspect your drains:

  • Check for slow draining or standing water.
  • Examine the pipes underneath for leaks.
  • Remove any visible debris from the drain openings.

If a drain is sluggish or clogged, use a plunger or drain cleaner to clear it. If the problem persists, you may need a professional drain inspection to address a deeper blockage.

4. Examine Your Water Heater

The water heater is a vital part of your plumbing system, and regular inspections can ensure it’s running efficiently. Look for the following:

  • Check for signs of leaks around the base or tank.
  • Examine the water heater’s pressure relief valve for signs of malfunction.
  • Look for rust, corrosion, or puddles around the unit.
  • Inspect the temperature setting and ensure it’s at the recommended 120°F to avoid scalding.

If you notice any unusual noises, leaks, or rust around the water heater, it’s time to schedule a professional water heater inspection to prevent further damage.

5. Look For Signs Of Water Damage

Water damage often starts small but can quickly escalate into costly repairs. Check around your plumbing fixtures for:

  • Stains, discolouration, or bubbling paint on walls or ceilings.
  • Dampness or mould growth around pipes, sinks, and tubs.
  • Wet spots on carpets, particularly near pipes.

Small leaks can cause significant water damage, leading to mould growth or structural issues. Early detection can save you from expensive repairs down the line.

6. Check The Shut-Off Valves

Your home’s plumbing system includes shut-off valves that control the water supply to various fixtures. Test these valves by turning them on and off to ensure they function correctly. If any valve is complex to turn or leaks, it may need replacement.

7. Inspect Sinks And Taps

Inspect the taps in your kitchen, bathrooms, and laundry room for leaks, water flow issues, and mineral buildup:

  • Look for leaks around the tap base.
  • Check for signs of corrosion or mineral buildup on tap aerators.
  • Ensure the tap is handled and operated smoothly.

If there’s any sign of a pipe leak or excessive buildup, clean the aerators or call a plumber for a more thorough inspection.

8. Test The Garbage Disposal

If your home has a garbage disposal, ensure it operates properly. Check for:

  • Strange noises or unpleasant smells.
  • Leaks or cracks around the unit.
  • Clogs or obstructions.

If your disposal isn’t working correctly, it could cause blockages and even affect your drainage system. For issues beyond basic troubleshooting, consider scheduling a professional plumbing inspection.

9. Inspect Outdoor Plumbing

Don’t forget to check your outdoor plumbing, especially if you have outdoor fixtures, irrigation systems, or hose bibs:

  • Check fixtures for leaks or cracks, particularly in winter when freezing occurs.
  • Inspect irrigation lines for any signs of damage or leaks.

Ensure all outdoor plumbing is in good working order to avoid leaks that could go unnoticed until they cause damage to your home or lawn.

10. Look For Blocked Vents

Proper ventilation is critical to your plumbing system, especially regarding sewer gases. Walk around your home and ensure all vent pipes are clear of debris and blockages. Blocked vents can cause drainage problems or slow drainage in toilets and sinks.

11. Check For Sump Pump Functionality

If your home has a sump pump, it’s essential to check it periodically:

  • Test the pump by pouring water into the pit and ensuring the pump turns on and drains the water efficiently.
  • Inspect the discharge pipe for any clogs or leaks.

A properly functioning sump pump prevents flooding in your basement or crawlspace. If it’s not working correctly, you may need a drain inspection and possible repair.
