Book this service when
Book this when a fixture or valve has started to weep, pressure has changed, the water bill has crept up with no change in use, or you want hose bibs and exposed lines checked after winter.
Common signs
- A fixture or valve has started to drip or weep and you are not sure how far the corrosion has gone
- Water pressure has changed noticeably — surging, dropping, or banging pipes — and you want the cause traced
- Your water bill has crept up with no change in usage, suggesting a leak you cannot see
- Winter has just ended and you want hose bibs and exposed lines checked before you turn the outdoor water back on

Inspection vs. maintenance, and how often you actually need it
There are two jobs here that people lump together. An inspection is a one-time assessment that tells you the true condition of the plumbing right now, which is what you want before a purchase, a renovation, or an insurance claim. Maintenance is the recurring version that keeps that picture current year over year, which for most GTA homes means once annually and twice for anything heavily used or pre-1970. Where an inspection turns up a drain that is slowing for reasons we cannot see from the fixture, we can extend the visit with a drain camera inspection to confirm what is going on inside the line rather than guess.
Signs it is time to book one
- A fixture or valve has started to drip or weep and you are not sure how far the corrosion has gone
- Water pressure has changed noticeably — surging, dropping, or banging pipes — and you want the cause traced
- Your water bill has crept up with no change in usage, suggesting a leak you cannot see
- Winter has just ended and you want hose bibs and exposed lines checked before you turn the outdoor water back on
- You are about to list your home and want plumbing issues found and documented before a buyer's inspector finds them
- You are finishing a basement and want the supply, drains, and flood-prevention gear confirmed sound before drywall goes up
What's included
- A licensed plumber on site walking the full system, using a pressure gauge and moisture readings rather than a visual glance alone
- Function testing of the equipment that actually fails — running the sump pump on its float and cycling shutoffs and valves to confirm they still operate
- A photo-documented written report that ranks every finding as fix-now, fix-soon, or monitor, so the list is usable instead of a wall of notes
- A 12-month maintenance schedule mapped to what we found, so you know what to budget and when
- An optional sewer camera add-on when a slow or suspect drain warrants seeing inside the line before any decision
- Carry-forward quotes for the recommended repairs, scoped from the report so nothing has to be re-diagnosed
- Any repair work we then perform from that report is backed by our written 25-year workmanship warranty
What we check during a whole-home inspection:
- Main shutoff and visible supply piping condition.
- Pressure test (incoming and at fixtures).
- PRV and expansion tank if installed.
- Fixture leaks, valves, and toilet operation.
- Drain function at every fixture.
- Water heater age, condition, and any visible leaks.
- Sump pump and float operation, basin condition.
- Backwater valve presence and accessibility.
- Visible signs of past leaks, ceiling stains, or water damage.
- Outdoor faucets and freeze protection.
When inspection makes sense
| Situation | Why inspection helps |
|---|---|
| Pre-purchase due diligence | Avoids inheriting problems hidden by surface finish. |
| Older home with mixed-age plumbing | Identifies what is approaching end of life. |
| Insurance request after a claim | Documents condition for the policy. |
| Renovation planning | Catches issues before drywall closes the wall. |
| Annual maintenance plan | Catches small issues before they fail. |
Inspection cost
A standard residential inspection is straightforward to price. Camera inspection on the sewer line, leak detection, or specialty work add to the scope. Pre-purchase inspections often combine plumbing inspection with sewer camera work for the most useful pre-deal information.
What to share when you call
- Why the inspection is being booked.
- Approximate age of the home.
- Any known issues or recent repairs.
- Whether sewer camera is part of the scope.
- Whether you want a written report for insurance or a deal closing.
- Any unfinished basement or attic access available.
Toronto context
Toronto homes — especially heritage properties and pre-1970 builds — accumulate quiet plumbing issues a homeowner never sees: aging shut-offs, hidden pinhole leaks, pressure creep, slow drain branches. An annual plumbing inspection catches them while they're cheap. We document what's flagged so you can budget the work in priority order.
When this is not enough
Inspection and maintenance surface issues — they do not fix them. When the report flags a major item (sewer damage, water heater near end-of-life, lead service line, failed backwater valve, water-pressure problem), the next step is a category-specific repair or replacement scope. The inspection report is built so you can carry it directly into that next step.
What to confirm before approving inspection
- The report should be written and prioritized — not just 'looks good'.
- Any flagged issue should include enough detail to follow up later.
- Pre-purchase reports should be deal-ready.
Useful info on the call: reason, home age, and whether camera or specialty work is part of the scope.
Why Is Plumbing Inspection Important?
A plumbing inspection involves assessing relevant, accessible components of a property's plumbing system and looking for signs of leaks, drainage problems, deterioration, or other concerns. The inspection process can vary depending on the property's age, plumbing layout, usage, and history of plumbing problems.
Toronto has a wide range of residential and commercial properties, from older homes to newer construction and busy commercial buildings. Older plumbing systems may require closer attention because components have experienced years of use, while newer properties may benefit from inspection before renovations, additions, or construction work.
An inspection is particularly useful when a plumbing problem keeps returning. For example, a drain that repeatedly becomes blocked may require more than another temporary clearing. Understanding the pattern can help determine whether additional drain or sewer service is necessary.
What Are the Signs Your Plumbing Needs Maintenance?
Plumbing problems do not always begin with a major leak or complete fixture failure. Slow drainage is one common warning sign. If a sink, bathtub, or shower consistently drains more slowly than it used to, there may be a developing drainage concern.
Recurring clogs are another reason to pay attention. An isolated blockage can happen occasionally, but repeated blockages may indicate an underlying issue. Property owners should also take notice of unexplained moisture, water around plumbing fixtures, persistent plumbing odours, unusual sounds from pipes or drains, and noticeable changes in water flow.
These symptoms do not automatically identify the cause. However, they provide useful information that can help a plumbing professional determine whether an inspection, repair, drain service, or sewer service is appropriate.
How Does Plumbing Maintenance Help Toronto Homes?
Residential plumbing systems experience regular use through kitchens, bathrooms, laundry areas, and other fixtures. Over time, everyday use can expose weaknesses or contribute to recurring drainage and plumbing problems.
Homeowners should pay attention to changes in how their plumbing performs instead of waiting until a fixture stops working completely. A history of leaks, recurring drain problems, sewer concerns, or previous plumbing repairs can also provide useful information when determining whether professional maintenance is needed.
Basements deserve particular attention because plumbing and drainage components may be located in these areas. Dampness, unusual odours, visible water, or recurring drainage problems should be investigated rather than simply cleaned up and forgotten.
Should Plumbing Be Inspected Before Renovations?
Renovations are another situation where Plumbing Inspection & Maintenance in Toronto can be useful. Kitchen, bathroom, and basement renovations can involve existing water supply and drainage systems. Understanding the condition of those systems before construction begins can help property owners plan the work more effectively.
New construction also requires careful plumbing planning. Tornado Plumbing & Drains provides new construction plumbing services in Toronto along with residential and commercial plumbing solutions. Considering plumbing requirements early in a project can help ensure the system is planned according to the property's needs.
Frequently asked questions
How long does an inspection take?
Most residential inspections take 1.5 to 2 hours, plus 30 to 60 minutes for the written report.
Does the inspection include a sewer camera?
It can be added. For pre-purchase due diligence on older Toronto homes, a sewer camera is often the most valuable piece.
Will you fix issues during the inspection?
Inspection is the assessment; we follow up with quotes for the recommended work. Some minor issues can be fixed on the same visit when scoped in advance.
Will my insurance accept the report?
Most insurers accept a licensed plumber's written assessment. Confirm format requirements with your insurer before booking.
How often should plumbing be inspected in Toronto?
There is no single inspection schedule for every property. Inspection needs depend on the property's age, plumbing condition, usage, and history of leaks, drainage problems, or repairs.
What are the common signs that plumbing needs maintenance?
Slow drains, recurring clogs, visible leaks, unexplained moisture, unusual plumbing odours, changes in water flow, and recurring basement plumbing problems can indicate that professional assessment may be appropriate.
Are recurring drain clogs a sign of a larger plumbing problem?
They can be. When the same drain repeatedly becomes blocked or drainage problems affect multiple fixtures, professional assessment can help determine whether there is an underlying drain or sewer issue.

August 2022“Tornado Plumbing and Drains did an excellent job replacing my old drains and correcting some very old plumbing in my old house in only 2 days. Peter was very thorough in evaluating and explaining in detail the problems with the drains and how they would be repaired. He was extremely patient in answering all of my concerns. The team showed up on time, protected the work areas and did an excellent job with the final clean-up. They are assisting me with the rebate for the valve also. The cost for the work was very reasonable and several thousand dollars less than two other companies. I have already recommended Tornado to several friends and recommend them without reservation.”

June 2020“I can’t recommend Tornado plumbing enough. Sergei and his team are literally the best. Sergei always provides the best recommendations and gives you his honest opinion. He doesn’t over sell and gives you the best advice. I had to have my main valve change which was something we had discussed a while ago from another service I had hired him for. The shut off valve was old and had lead component. I knew from past experience that anytime I needed to turn it on or off, it would start leaking. There was also a lead pipe leading underground. I made the decision to change all the lead pipe as opposed to just changing the shut off valve because it would eventually need to be changed regardless. Sergei dug from the front of my house to the water valve in my basement with minimal interruptions to my tenants, and minimal mess. This speaks to his attention to detail. He goes over and beyond my expectations. Thank you Sergei and Tornado Plumbing.”
