Plumbing Inspection in Ottawa — Sewer Camera & Home Checks

A general home inspector looks at the whole house in a few hours. Plumbing gets a visual check: running taps, flushing toilets, looking at the water heater label. That is useful, but it cannot show what is happening inside the drain lines buried under the basement slab or running out to the street.

The sewer lateral, the pipe that carries waste from the house to the municipal sewer, is often the most expensive plumbing component to repair and the least visible. A camera inspection is the practical way to see it. Buyers who skip it may find out about a damaged lateral only after the first backup.

A waterproof camera on a flexible cable is pushed through a cleanout or drain opening. The plumber watches a live feed and can usually estimate the distance to any defect. Common findings include tree roots entering through joints, cracked or broken pipe, offset joints where sections have shifted, sags or bellies that hold water, grease and scale buildup, and sections that have collapsed.

Not every defect needs immediate repair. A small amount of scale may only need monitoring, while a collapsed section usually needs repair. The value of the camera is that you decide based on what is actually there rather than guessing.

In Ottawa, responsibility for the sewer lateral is generally split between the property owner and the City, with the boundary typically at the property line. The details matter if a defect is found near the street, so check the City of Ottawa's sewer information or contact 3-1-1 to confirm responsibility for your address.

A camera inspection that records the distance to a defect helps answer that question. If the problem appears to be on the City's side, report it before arranging private repair work.

The best time for a plumbing inspection is during the conditional period of an offer. Talk to your real estate agent about including an inspection condition and allowing enough time to book a plumber. Ask the seller's permission for access to cleanouts and the basement.

If the inspection finds a significant problem, you have options: ask for a price adjustment, request repairs before closing, or walk away under the condition. A written finding is more persuasive in those conversations than a verbal concern.

Many older Ottawa homes have a mix of pipe materials. Copper supply lines are common and usually durable. Galvanized steel supply pipe can corrode inside and reduce water pressure over time. Cast-iron drain stacks can crack or rust through, and clay sewer laterals are vulnerable to roots at the joints.

Some homes built before the mid-1950s may have a lead water service pipe. An inspection can note suspected lead, but confirmation and testing should follow City of Ottawa and Health Canada guidance. Do not rely on a visual inspection alone to decide whether your drinking water is safe.

Multiple drains slowing at the same time, gurgling from a floor drain when the washing machine empties, a toilet that bubbles when a tub drains, sewer odours in the basement, and backups after heavy rain are all signs the main line deserves a look.

Trees planted near the sewer path are another reason, especially willows, maples and poplars, whose roots seek out moisture. If your drain has been cleared more than once in a year, a camera inspection is usually cheaper than repeated clears.

A leak investigation starts with simple checks. With every fixture off, the water meter should not move. If it does, water is going somewhere. The plumber then works through toilets, which commonly leak silently through the flapper, then valves, visible pipe and appliance connections.

Hidden leaks behind walls or under floors may need further investigation. Ask what will be opened, who restores the surface afterward and whether the estimate covers it. A good inspection narrows the search before anything is cut.

The water heater label shows its age, and most tank heaters have a typical lifespan of around 10 to 12 years. The inspection looks for rust at the base, leaking fittings, a missing or improperly piped relief valve discharge line and signs of sediment problems such as rumbling.

If the water heater is rented, the inspection can note its condition, but the rental company is responsible for its repair. Confirm the terms of your rental agreement before arranging any work on a rented tank.

Many Ottawa homes, especially those that have experienced basement flooding, have or should have a backwater valve. An inspection can check whether one is present, whether it is accessible and whether the flap moves freely. A valve that is buried, seized or full of debris may not protect the home when it matters.

The City of Ottawa's Residential Protective Plumbing Program has helped eligible homeowners pay for backwater valves and sump pumps. Program terms and amounts change, so check the City's current information before planning work.

Rental properties benefit from scheduled inspections between tenants or once a year. Checking shut-off valves, toilet internals, water heater condition and drain flow catches small issues before they become urgent tenant calls.

Written reports give landlords a record of the plumbing's condition, which helps when planning budgets and responding to maintenance requests. Ontario's rental rules require landlords to keep plumbing in good repair, so a documented inspection supports that responsibility.

Moving a fixture, adding a bathroom or changing drain layout usually requires a building permit in Ottawa, and new plumbing may need to be tested and inspected by the City before it is covered. Testing new drain work, for example with water or air tests, shows the system holds without leaking.

A pre-renovation plumbing inspection identifies which existing pipes to replace while the walls are open, so you are not closing up tired pipework behind new finishes. Ask your contractor and the City which inspections your project requires.

Ask what the inspection includes, whether a camera is used, how the drain will be accessed, whether you receive photos, video or a written summary, and how long the visit will take. Ask whether the price changes if the line is blocked and needs clearing before the camera can pass.

Most importantly, ask whether repair recommendations are quoted separately. You should be free to get a second opinion before committing to any major repair found during an inspection.
