That’s why thousands of homeowners across Mississauga, Oakville, Hamilton, Milton, Niagara, and Cambridge have trusted BOS Plumbing & Drains to install and maintain their drainage systems. Here’s what makes us the best plumbers near you for drain line installation:
Your home’s plumbing system is made up of two networks: the supply lines that bring fresh water in, and the drain lines that carry wastewater out. Drain line installation is the process of running new drain pipes that connect your home’s fixtures, sinks, showers, bathtubs, toilets, washing machines, dishwashers, and floor drains to your main stack and ultimately to the municipal sewer system.
It’s a fundamentally different service from drain repair. Where drain repair addresses problems with existing pipes, cracks, blockages, a drain pipe clogged by years of buildupdrain line installation creates entirely new drainage pathways from scratch. Whether you’re building new, renovating, or expanding your home, new drain lines are the foundation your plumbing is built on.
A proper drain line installation comes down to three non-negotiable factors:
Get all three right as BOS Plumbing & Drains does on every installation and your drain lines will perform reliably for 30 to 50 years. Get one wrong, and you’ll be calling a plumber for drain repair long before you should have to.
Not sure whether your home needs new drain lines installed, or whether you’re dealing with a drain repair situation? Here’s how to tell:
You likely need Drain Line Installation if:
You likely need Drain Repair or Drain Cleaning if:
If you’re experiencing any of the drain issues above slow drains, recurring drain clogs, a drain pipe clogged beyond what a plunger can fixBOS also offers professional drain cleaning near me services. This includes snaking a drain and hydro-jetting to clear blockages fast.
In fact, if a simple clog has turned into a recurring problem, it often signals a deeper issue with your drain pipe that requires professional diagnosis. Our plumbers will assess whether you need drain cleaning, drain repair, or a full new drain line installation and give you an honest, no-pressure recommendation.
New Home Construction: Every new home needs a complete drainage system built from the ground up. This means planning the layout of all fixtures, routing drain pipes through walls, floors, and foundations, calculating the correct slope throughout the entire system, and making the final connection to the municipal sewer. BOS works with builders, general contractors, and homeowners on new construction residential plumbing installations across Mississauga, Oakville, Hamilton, Milton, Niagara, and Cambridge delivering code-compliant systems that pass inspection for the first time.
Basement Finishing: Finishing your basement almost always requires new drain line installation. Whether you’re adding a bathroom, laundry room, wet bar, or utility sink, your new fixtures need proper drain pipes connected to your home’s main plumbing system. Basement installations are technically more complex than above-grade work because fixtures often sit below the main sewer line, requiring additional solutions like sewage ejector pumps. BOS has extensive experience with basement drainage across the GTA.
Kitchen & Bathroom Renovations: Moving a sink, adding a kitchen island, relocating a shower, or reconfiguring a bathroom requires new drain pipe routing. Even minor fixture relocation demands significant changes to what’s hidden inside your walls and under your floors. Our licensed plumbers handle all aspects of renovation drain installation from the initial planning through to final inspection sign-off.
Adding New Bathrooms or Fixtures: Every new bathroom/powder room, ensuite, in-law suite needs its own dedicated drain lines properly connected to your home’s drain-waste-vent (DWV) system. Same applies to any new drain for a sink, outdoor kitchen, or utility fixture you’re adding.
New Appliances Requiring Drainage: Dishwashers, washing machines, water softeners, and ice makers all require dedicated drain pipe connections. Improper connections or connections that are simply too small cause backflow, flooding, and drainage problems that affect your entire house plumbing system.
French Drain Installation: If your property has surface water drainage issues, water pooling near your foundation, a soggy lawn, or chronic basement moisture a French drain line may be the solution. A French drain is a gravel-filled trench containing a perforated pipe that redirects surface water and groundwater away from your home’s foundation. BOS designs and installs French drain systems as part of our complete exterior drainage service across our entire service area.
Replacing Old or Damaged Drain Pipes: Homes built before the 1980s often have original clay, cast iron, or early ABS drain lines that are long past their useful life. Rather than continuing to call for drain repair on a system that’s fundamentally failing, replacement with new PVC drain lines is often more cost-effective in the long run. BOS handles complete drain system replacement with minimal disruption.
BOS Plumbing & Drains is your trusted residential plumbing specialist for drain line installation across Mississauga, Oakville, Hamilton, Milton, Niagara, Cambridge, and the wider GTA. We work with homeowners, builders, and contractors on projects of every size and complexity from a single new drain for a sink to a full-home drainage system installation.
Every residential installation is completed to Ontario Building Code standards, fully permitted, and ready for municipal inspection. Whether you’re a first-time homeowner tackling your first renovation or a builder who needs a reliable plumbing service near me to partner across multiple projects, BOS delivers consistent, professional results.
Basements present unique drainage challenges compared to above-grade work. Being below grade means fixtures often can’t rely on gravity alone to drain into the main sewer, requiring careful engineering and sometimes additional equipment like sewage ejector pumps.
BOS installs basement drain lines for:
A correctly installed basement drain system prevents backflow, controls humidity, and protects your finished investment from water damage. Our team has installed hundreds of basement drain systems across Mississauga, Oakville, Hamilton, and the GTAwe know every configuration and every challenge this type of work presents.
Bathrooms and kitchens place the highest daily demands on your home’s drain pipes. BOS installs drain lines for:
Bathroom Drain Installation
Kitchen Drain Installation
Kitchen drain pipes handle grease, food particles, and high water volumes every single day. Getting the installation right from day one with the correct slope, proper venting, and the right pipe diameter prevents the chronic drain clog and slow-drain problems that plague poorly installed kitchen drainage systems.
Dishwasher Drain Line Dishwashers require properly configured drain lines with correct air gaps to prevent backflow and contamination of your clean dishwater. We install dishwasher drain connections to code and test them fully before completion.
Washing Machine Drain Line
Your washer uses a lot of water, 15 to 20 gallons for each cycle in less than one minute. The drain pipe must be the right size and properly vented to accommodate the flow without overflowing in the laundry room. BOS uses standpipes of the right height and diameter in washer drain lines to prevent drain overflow and damage to your house plumbing.
Water Softener Drain Line
Water softeners discharge waste water during regeneration. We use water softener drains of the proper size and gradient to accommodate these flush cycles without interfering with your drainage system.
Sump Pump Discharge Line
Sump pumps are only as good as their discharge line. BOS sump pump discharge lines carry water away from your foundation to a city drain, approved drainage ditch or other approved drainage. We always follow local building code, because if the discharge line brings water back towards your foundation, it defeats the purpose of installing the pump.
When you need to run drain pipes under driveways, patios, landscaping and other surfaces, digging means destroying what’s on top of the pipes. We can avoid all that with trenchless drain line installation; we replace drain pipes without a lot of digging using today’s no-dig technology.
Trenchless installation is ideal for:

Here’s what goes wrong with DIY drain installations:
Absolutely, drain line installation needs to be done by licensed plumbers. You need to know construction rules, how to install things correctly, and how these systems actually drain. Trying to install a drain line yourself can often lead to issues like code violations, inspections that don’t pass, leaks or drainage problems and you end up spending more than just hiring a professional in the first place.
The timeline for drain line installation depends on the project’s scope and complexity.

Larger projects like those with many light fixtures or places that are hard to gain access to, might take us a few days to complete.

Absolutely. In fact, renovations are one of the most common times for drain line installation. Whether you’re modernizing your kitchen, putting in a new bathroom, or finishing your basement, we work with your renovation timeline to make sure drain lines are installed exactly when needed.
In most cases, yes. You’ll usually need a plumbing permit from your local municipality for drain line installation. These permits make sure that the work follows building codes, so everything is checked for safety and to be sure it’s up to standard. As licensed plumbers, we take care of getting all the necessary permits and setting up inspections as part of our service.
