Before making any verbal or written promises when buying a new house, it is crucial to carry out your due diligence in the form of a professional home inspection. Plumbing home inspection is an essential element, but you should make sure that your plumbing inspection checklist covers the primary components. If you discover that crucial systems are not included in that agreement, see if you can get them included with the help of your inspection company or a dependable plumbing firm.


We frequently neglect the plumbing inspection requirements in our homes. It’s critical to remember that little plumbing problems can develop into more expensive problems. Since we rely on our plumbing systems every day, it’s crucial to have a thorough plumbing checklist. This post will outline an essential plumbing inspection checklist, the possible advantages, and the recommended time frames.

What is a Plumbing Inspection?

A plumbing inspection is a comprehensive look at your plumbing system. In a professional plumbing inspection checklist, the inspector will examine these items and systems:

  • Indoor and outdoor pipes
  • Hose bibs
  • Sinks and bathtubs
  • Faucets and showers
  • Toilets
  • Water heaters

What is the Importance of Plumbing Inspection?

Provides a longer lifespan to your water systems

Early problem detection allows your plumbing systems to function successfully and efficiently. Any additional strain may shorten your plumbing system’s lifespan. Inspections of your plumbing system regularly relieve stress on your system and extend its longevity.

Reduces the utility bills

Your water rates might go up if leaks or fractures go undiscovered. Your overall water usage will be up because of continuous flow. Your plumber will check each system individually throughout your inspection. Money saved. 

Chances of fewer repairs

Plumbing inspections will reduce your repair expenses. Your system as a whole may sustain costly damage from leaks or blockages, and your property may sustain additional harm from mould growth, wood rot, or foundation repairs. By preventing these repairs, early problem detection will help you save money.

Improves air quality

Mould or mildew development can result from plumbing system leaks. Poor air quality in your house may result from mould or mildew growth. Plumbing inspections may improve the air quality in your home by assisting in preventing mould and mildew growth.

Improves water quality

Our plumber may inspect any installed water filtration systems while doing a plumbing inspection. There should be no pollutants or dirt in your water. Because of this, plumbing inspection may enhance your water and air quality.

Reduces plumbing emergencies

The most inconvenient moments are when plumbing crises occur. Plumbing problems can cost your property a lot of money to repair. The structure of your house and your health may be at risk from this. Through the identification of potential major issues and the recommendation of appropriate safety measures or early repairs, routine plumbing inspections can reduce the likelihood of plumbing crises.

Reduces your stress

To prevent tension and concern, plumbing inspections might find issues. Even in situations where clients would prefer to wait for plumbing repairs, we can recommend smart leak detectors and cut-offs to help you keep an eye on potential problems while staying connected to safety precautions. Give yourself peace of mind that your home’s plumbing system is functioning correctly. Regular plumbing inspections may lower expenditures while also lowering stress levels.

Efficient water pressure 

Your water pressure may be reduced by corrosion buildup, roots, or leaks. Your pleasure with your home’s water system may decline due to declining water pressure, which may prompt unneeded purchases. Plumbing fittings in your home may become damaged by high water pressure.

Why Should You Get A Plumbing Inspection?

You might believe that a thorough plumbing inspection is part of the home inspection if you’re purchasing a house. But a conventional house inspection’s plumbing inspection often just looks at three things: if the drains are clear, the toilets are flushing, and the faucets are functioning. There are several other items on the plumbing inspection checklist for a thorough plumbing inspection carried out by a certified plumber. Here are four explanations of why you should get a qualified inspection.

You’re buying a home.

As we just explained, regular house inspections fall short of a complete professional plumbing check. When making a significant investment, especially in an older property, it pays to look out for any issues before signing the contract.

You’re selling your home.

Inspections of the plumbing system may help market a property to potential buyers. You’ll be able to demonstrate without a shadow of a doubt that your property’s plumbing systems, sewage lines, and other plumbing-related components are in excellent condition.

You want to avoid costly plumbing emergencies.

A prudent homeowner doesn’t wait for a system to break down. Regular plumbing inspections can stop minor issues from growing into major ones.

You want to protect your home.

When everything is taken into account, this is most likely the finest justification for having your plumbing systems evaluated. Even a minor leak or clogged drain can create severe, difficult-to-locate, and expensive fix damage. Probably more expensive than a plumbing checkup as well!

Checklist for Plumbing Inspections Before Buying a Home

1. Toilets

Before filling the bowl with water, ensure all toilets flush correctly and completely drain. Ensure the toilet is secured to the floor with bolts and the area surrounding the base is free of leaks.

2. Shower

A plumbing inspection for each shower in the home comprises turning on all the faucets, looking at the shower heads themselves, and checking the drains. If the fixture has a switch that allows you to go from the tub spigot to the showerhead, you must make sure the water pressure varies at each location and the flow of water changes correspondingly. 

3. Faucets and Sinks

It’s also a good idea to test the faucet and drain on every sink in the home. Ensure the inspector opens and closes the drain stop on each faucet to ensure the water drains properly. After turning off the faucets, check to see whether there is any dripping.

4. Kitchen Sink and Garbage Disposal

The build-up in the kitchen sink drain over time can cause partial or complete blockages that need to be fixed by a professional. The plumbing inspector should test the faucet, look for leaks in the pipes under the sink basin, and ensure the kitchen sink drains appropriately. Ask them to activate the waste disposal to make sure it also functions.

5. Water Heater

A crucial appliance to check is your water heater. Tanked water heaters, which are common in houses and typically last ten years, need to be inspected and maintained. Ask the qualified inspection expert when the tank was last flushed, request that the anode rod be inspected for tank rust prevention, and check to see whether the water heater is functioning correctly by testing the hot water supply in the house.

6. Sewer System

You might want to get in touch with a nearby plumbing business to have them do a video camera examination of the sewage pipes, regardless of the kind of sewer system you have. If the home’s plumbing does not connect to a public sewage system, the septic tank system must be inspected to ensure no blockages or seepage might be dangerous and expensive to repair. If feasible, write down when the septic tank was last serviced or emptied.

7. Leak Inspection

Any home can have significant problems from leaks, whether they happen in easily accessible or inaccessible areas. It’s frequently advisable to have a qualified plumber check the house for leaks and run a test with the water metre if this service is not included in the inspection to prevent potentially significant water damage and expensive repairs.

8. Inspect the Pipes

The plumbing system as a whole is connected via pipes. Any damage to these pipes will have an impact on the entire plumbing system, and once pipes are in use, they are challenging to repair or replace.

Check for the following things:

  • Rust shouldn’t develop on pipes.
  • When it comes to plastic pipes, the material should be acceptable.
  • Since lead is dangerous, all lead pipes should be replaced.
  • Turn on each faucet and listen for any loud pipes.
  • These two tests are used to check for leakage:

9. Assess the Sewage System and Septic Tank

The municipal sewer systems in specific older communities are out-of-date, and invasive tree roots can interfere with your plumbing and septic system. Your plumber will examine each of these qualities more closely and provide advice on:

  • Local sewage problems are frequent
  • Cost of sewer line replacement or repair, if necessary
  • Outdated and damaged cast iron pipes or ceramic tile
  • Shifting terrain
  • The septic tank’s location, the state of the pipes leading to it, and the times since the last maintenance were performed
  • Drainage and smell of sewage

10. Identify Slab Leaks

Nowadays, most building firms erect houses on concrete slabs, which are often poured over the basic plumbing setup. If left unchecked, cracks, pressure, and corrosion can eventually result in leaks and significant damage. Your contractor will look out for these indications of a slab leak:

  • Inadequate water pressure
  • Very high water costs
  • Hearing water running without an apparent reason
  • Floor fissures
  • Unidentified water on the ground
  • Patches on the floor that are warm to the touch
  • Under carpet moulds


Until the transaction is finalised, the current owner must report and remedy any plumbing concerns that may occur. Because plumbing system repairs can be expensive, you must be meticulous in your plumbing inspection checklist. Contact a staff member if you need assistance with a qualified plumbing inspection.
