Drain Cleaning in Ottawa — Clogged Drains, Sewer Lines & Hydro Jetting

Every fixture in your home drains through a trap — the U-shaped bend that holds water to block sewer gas — into branch lines, then into the main stack and finally the building sewer, or lateral, that runs under your yard to the City main.

The City of Ottawa is generally responsible for the sewer main and, in many cases, part of the lateral under the road allowance. The homeowner is usually responsible for the portion on private property. The City's 311 service can tell you where that line falls for your address.

If only one fixture is slow, the clog is in that fixture's trap or branch line. A plunger or a simple cable often clears it.

If several fixtures are affected — the toilet gurgles when the washer drains, or water appears at the basement floor drain — the blockage is in the main line. Stop using water and call for professional clearing; continued use can push sewage into your basement.

Caustic drain cleaners can generate heat that softens plastic pipe and accelerates corrosion in old metal pipe. They rarely clear a full blockage and leave a dangerous liquid sitting in the line for the plumber who comes next.

An enzyme-based maintenance product is gentler for routine use, but no product replaces mechanical clearing for a real clog. If you've already poured chemicals in, tell your plumber before they start.

Roots are attracted to moisture and nutrients leaking from tiny gaps in pipe joints. Once inside, they grow into a net that catches paper and waste. Clay tile and older cast-iron pipes are most vulnerable.

Cutting roots restores flow, but they'll grow back. A camera inspection tells you how bad the intrusion is and whether maintenance clearing every year or two, a spot repair, or lining or replacing the lateral is the best long-term choice.

Fats, oils and grease go down the drain as a liquid and solidify as they cool, coating the pipe and trapping food particles. The City of Ottawa asks residents not to pour grease down drains for exactly this reason — it causes blockages in private pipes and public sewers alike.

Let grease cool, scrape it into the green bin, and wipe pans before washing. For a kitchen line that already has heavy buildup, hydro jetting removes grease from the full pipe wall.

A backwater valve installed on the main sewer line closes when municipal water flows backwards, protecting your basement. A sump pump with a backup removes groundwater from around the foundation. Together they're the most effective protection against basement flooding.

Valves need periodic inspection to make sure the flap moves freely. If you have one, ask us to check it on your next visit. If you don't, check the City of Ottawa's protective plumbing subsidy before you book the installation.

A standard home inspection usually doesn't include the sewer lateral. Yet replacing a broken lateral can be one of the most expensive repairs a homeowner faces. A sewer camera inspection before you buy — especially for an older home with mature trees — gives you facts to negotiate with.

We provide the video and a plain-language summary of what we found, including the location and depth of any problem.

Use hair catchers in showers, only flush toilet paper — even 'flushable' wipes cause blockages — and run hot water after using the kitchen sink. Pour a bucket of water into rarely used floor drains every few months to keep the trap from drying out.

If you have a history of root problems, scheduled maintenance clearing is cheaper than an emergency call on a holiday weekend.

Shared drain lines in condos and stacked townhomes mean a blockage in one unit can affect neighbours. If water backs up into your sink when a neighbour runs their dishwasher, the shared branch or stack is likely partly blocked.

We coordinate with property management, clear the line from the appropriate access point and, where needed, camera the stack so the condo corporation knows whether there's a building-wide problem to plan for.

When a camera inspection reveals a cracked, offset or collapsed lateral, there are several repair options. A spot repair replaces only the damaged section. Trenchless pipe lining installs a new pipe inside the old one with minimal digging. Full replacement may be best when the line is failing along its length.

We explain each option, its trade-offs and what permits or City coordination it needs, then put the choices in writing so you can decide calmly — not in the middle of a backup.

Stop using water immediately — no flushing, showers or laundry. Keep children and pets away from the water, and don't touch it without gloves; sewage carries bacteria. If water is near electrical outlets or appliances, stay out of the area until power is safely turned off.

Then call our 24/7 line. Take photos for your insurer before cleanup, and keep receipts for any damaged items. Once the line is cleared, we can give you a written description of the cause for your claim.

Homes on septic systems in areas like Greely, Carp, Dunrobin and Osgoode need a different approach. Clearing a blockage between the house and the tank is routine, but a backup can also mean the tank needs pumping or the leaching bed is struggling.

We clear the house drain and tell you whether the problem looks like a pipe blockage or a septic system issue, so you know whether to call a septic pumping company as well.

A sewer smell inside the home usually means a trap has dried out, a vent is blocked, a wax ring under a toilet has failed, or a cleanout cap is loose. Kitchen drain odours more often come from food and grease buildup inside the pipe.

We trace the source with smoke or visual testing, then fix the cause — refilling and priming traps, resealing toilets, clearing vents or cleaning the line — rather than masking the smell.

Restaurants, apartment buildings and offices place heavier demands on drains. Kitchen stacks in residential buildings collect grease from dozens of units, and restaurant lines carry fats even with a working interceptor.

Scheduled hydro jetting keeps these lines flowing. See our commercial plumbing page for maintenance plans, stack cleaning and grease interceptor service across Ottawa.

Recurring backups after clearing, water pooling in the yard above the sewer line, sinkholes, lush patches of grass in dry weather, rodents or insects around floor drains, and cracks in the basement floor near the drain can all indicate a damaged lateral.

Any of these is a reason to book a camera inspection before the next backup.
