KITCHEN DRAINS
Grease clogs are the number one preventable plumbing problem our crews clear in Metro Vancouver kitchens. The pattern is always the same: months of bacon fat, butter and cooking oil rinsed down the sink, then one evening the basin fills on its own, the dishwasher backs up into it, and a normal dinner becomes a night of buckets and panic. What most homeowners do not realize is that the clog was building the entire time, one invisible layer at a time, with zero symptoms until the pipe was more than half blocked.
This guide covers why grease behaves so badly in our cool coastal pipes, what a professional clearing actually costs in 2026, the habits that stop buildup before it starts, and the warning signs that tell you a clog is weeks away rather than days. Prevention is genuinely cheap here: the entire toolkit costs less than a single emergency service call, and every habit takes under a minute.
If your sink is backing up right now, stop running water, skip the caustic chemicals, and call us at 604-615-2212. We clear kitchen lines across Vancouver, Burnaby, New Westminster and Surrey six days a week, and after-hours service is available with the $150 flat surcharge disclosed before dispatch.
THE SCIENCE
Why Grease and Kitchen Drains Are a Worse Match in BC Than Almost Anywhere
The rule that matters: fats, oils and grease, what the industry calls FOG, are liquids in the pan and solids in the pipe. Animal fats liquefy around 40 to 50 degrees Celsius and solidify again as they cool. By the time that burger grease travels five metres through your drain line, it has dropped to the temperature of the soil and concrete around it, and it coats the pipe wall as a waxy film. Every rinse adds a layer, and the layers never leave on their own.
Coastal BC makes it worse, not better. Our groundwater and pipe surroundings sit cool year-round, so grease sets faster and further upstream than in hot-climate cities. There is no summer heat soaking into your slab to soften anything. A kitchen line in a slab-on-grade home in Surrey or a crawlspace home in Coquitlam is a cold pipe in cold ground, twelve months a year.
Pipe material decides how fast the film becomes a clog. Modern ABS and PVC drains are smooth, so grease layers build slowly and evenly. But huge parts of Vancouver, New Westminster and North Vancouver still run cast-iron drains from the 1950s through the 1970s, and cast iron that has decades of corrosion has a rough, pitted interior that grips grease like sandpaper. In those homes, grease and rust build on each other: the grease captures debris, the debris slows flow, and the slowed flow deposits more grease. A line that drains "fine" at 40 percent blocked can fail to drain at all within weeks of Thanksgiving.
Downstream, the story scales up. Metro Vancouver utilities spend millions every year clearing FOG blockages from sewers, and "wipe before you rinse" campaigns exist because the consequence of a blocked main is a basement full of someone else's sewage. What you send down the kitchen drain does not vanish; it either makes it to the treatment plant or it stops somewhere it should not, and the nearest wall it sticks to might be your own.
The cooling zone
Liquid fat hits solid within the first metres of your drain line. That is why grease clogs form in the kitchen branch and building drain, not at the city main, and why they are yours to clear.
The silent half
Drain flow stays normal until roughly half the diameter is gone, then falls off a cliff. "It drained fine yesterday" is exactly how grease clogs behave, and it is why they always feel sudden.
The rough pipe multiplier
Old cast-iron drains in Vancouver and New Westminster homes grip grease far faster than smooth plastic. If your 1960s house has never had the drains scoped, assume there is a grease shelf already.
The holiday spike
October through December is grease clog season in BC: turkeys, roasts and deep-fry weekends concentrate a year of fat into eight weeks. Plumbers know the calendar before the phones ring.
2026 PRICING
What a Grease Clog Actually Costs to Clear in Metro Vancouver
The DIY route first, honestly: a cup plunger costs $15 and occasionally clears a soft blockage at the trap. A 6-metre hand snake costs $40 and sometimes punches through grease, leaving the buildup behind to re-close within weeks. Caustic drain cleaners, $10 to $20 a bottle, generate heat and foam but barely dent a true grease plug, and in old pipe they can attack already-thin cast iron. We regularly follow a chemical bottle with a machine cable because the chemical never reached the clog; it just sat in the fixture.
Professional clearing is priced by method and access. Here is what Metro Vancouver homeowners paid in 2026.
| Service | 2026 cost (CAD) | When you need it |
|---|---|---|
| Kitchen branch drain cleaning (machine cable) | $189-$450 | Sink backed up, dishwasher reflux, first-time clog |
| Hydro-jetting (kitchen line) | $450-$900 | Recurring clogs, heavy grease, restored full diameter |
| Drain camera inspection | $250-$400 | Verifying pipe condition after clearing, or pre-purchase |
| Enzyme foam maintenance treatment | $150-$250 | Annual or semi-annual prevention on busy kitchens |
| After-hours emergency dispatch | +$150 flat | Disclosed before we roll, weekends and nights |
| Sewer line repair or replacement (worst case) | $5,000-$30,000 | Collapsed or root-bound pipe that grease finished off |
Two notes on that bottom row. Grease rarely breaks a pipe by itself, but it is a wonderful accomplice: it feeds tree roots at joint gaps, hides bellies and cracks from casual clearing, and adds weight to a line already failing. When a jetted line still will not hold, a camera tells you why, and our guides to sewer camera inspection costs and trenchless sewer repair costs walk through what happens next. For the everyday version of this pricing, the emergency plumber cost guide for Surrey breaks down how after-hours billing works across the region.
Pro tip: if your kitchen has needed the drain cleared twice in one year, stop paying for cables and buy one jetting. Hydro-jetting scrubs the pipe back to full diameter with high-pressure water and cuts grease off the wall instead of poking a hole through it. It costs two to three times a cable visit and removes the reason you keep calling.
PREVENTION
Seven Habits That Prevent Grease Clogs in a BC Kitchen
None of this is complicated, and all of it is cheaper than one service call. Pick the habits that fit your kitchen and make them automatic before the holidays arrive.
1. Can it, cool it, green bin it
Keep a tin can or jar by the stove. Pour fats and oils in while warm, let them solidify, then scrape into your green bin. Metro Vancouver's organics program takes small amounts of solid fat and grease-soaked paper towels; liquid grease in any quantity never belongs in a drain.
2. Wipe before you rinse
A dry paper towel removes 90 percent of the fat on a pan before it ever meets water. Wipe greasy pans, plates and the bacon tray into the green bin first. This single habit prevents most residential grease clogs we clear.
3. Run a sink strainer
A $10 to $20 stainless basket strainer stops food scraps from riding grease into the trap. Empty it into the green bin every dish session. Bits of rice and pasta swell in water and act as aggregate in a grease dam.
4. Respect the cold-water rule (for disposals only)
If you use a disposal, run cold water before, during and after: cold keeps any fat solid so the grinder can break it into pieces rather than smear it as liquid along the pipe wall. Hot water with a disposal liquifies grease and coats everything downstream.
5. Treat the line monthly
Biological and enzyme treatments, $15 to $35 a bottle, digest the fat film slowly and safely. Pour them in at bedtime so they sit for hours. They maintain a clean line; they do not rescue a blocked one.
6. Book a pre-holiday clean-out
If your kitchen has a history, schedule a professional cleaning or jetting in early November before the turkey fat arrives. Our drain cleaning before winter guide covers the full seasonal checklist for BC homes.
7. Teach the house rules to everyone
The best habits die at a holiday dinner when a helpful guest tips the roasting pan into the sink. Put a note by the tap in December. It costs nothing and saves the night.
A word on the most common question we get: no, dish soap does not save you. Soap emulsifies grease so it travels further before separating, which means the layer forms deeper in the system instead of at the trap. It is a cleaning tool for dishes, not a drain treatment.
GARBAGE DISPOSALS
Your Garbage Disposal Is Not a Grease Disposal
Garbage disposals occupy a strange place in Metro Vancouver homes. Plenty of houses have them; almost no one should be using them the way they do. A disposal grinds food into smaller pieces, but it does not digest anything. Fat goes through ground up or liquefied, and it re-solidifies in exactly the same place it would have without the machine. The unit buys you smaller particles, not chemistry.
The region's preference is the green bin, not the drain. Metro Vancouver's waste strategy asks households to compost food scraps precisely because solids in the sewer cost treatment money and cause blockages, and many strata corporations in Vancouver and Burnaby towers have banned disposals outright to protect aging risers that were never designed for ground-up solids from forty units at once. If you live in a condo with a disposal, your kitchen branch may be shared with neighbours whose habits you cannot control, which is the strongest argument for your own prevention habits being airtight.
If you keep yours, run it with cold water as described above, feed scraps gradually rather than in batches, and never send it grease, oils, bones, coffee grounds, eggshells, pasta, rice or stringy celery. Coffee grounds are the sneaky one: they do not rot the way food does, they settle and pack into grease layers like sand in mortar. Every plumber in the region has pulled a "coffee and grease conglomerate" from a kitchen line that the owner swore was only used for lettuce.
EARLY WARNING
Warning Signs Your Kitchen Line Is Building a Grease Plug
Grease announces itself politely for weeks and then rudely in one evening. Catch it at the polite stage and a $189 clearing or even a $150 enzyme treatment handles it. Wait for the rude stage and you are into jetting, cameras and possibly worse.
Slow emptying that improves then returns. The basin takes 30 seconds to drain on Monday, fine by Thursday, slow again the next week. That oscillation is a grease shelf alternately softening and re-hardening with water temperature. It is the single most reliable early sign.
Gurgling from the vent. Air trapped behind a partial blockage burps back up through the sink or the dishwasher connection. Gurgling means the flow path is already restricted enough to matter.
Dishwasher backup into the sink. The dishwasher discharges into the kitchen drain upstream of the trap. If its water pulses up into your basin, the line downstream is partially plugged right now.
Fruit flies and drain odour. A grease film is an all-you-can-eat buffet for organic growth. Persistent small flies around a clean kitchen usually mean the drain, not the fruit bowl.
Multiple fixtures at once. When the kitchen sink, laundry and a basement floor drain all slow together, the blockage has moved past the kitchen branch into the building drain, which changes the job from branch clearing to mainline work. That is the moment to scope rather than snake blindly, because in older New Westminster and Vancouver homes the building drain is also where roots and broken cast iron live.
One simple weekly test costs nothing: fill the kitchen basin half full and pull the plug while watching the second basin and the dishwasher air gap. Water should spiral down in seconds with no rise anywhere else. If any fixture reacts, the line is telling you it is half full of something.
HOLIDAY SEASON
Thanksgiving to New Year: How to Survive Grease Clog Season
Ask any plumber in the Lower Mainland about the week after Canadian Thanksgiving and you will get a tired smile. October's turkey, November's roasts and December's deep-fry experiments concentrate an entire year of fat into ten weeks, and the emergency calls line up accordingly. One large bird yields a cup or more of pan fat; a deep-fryer holds three to five litres of oil. Where that fat goes decides your January.
Big-decimal rules for holiday cooking: strain and reuse fryer oil where practical, then cool and containerize it for a recycling depot or, in small amounts, the green bin after solidifying with absorbent. Designate one "grease captain" at family dinners so pans are not automatically headed for the sink while the cook is carving. Keep the strainer in place even when guests are stacking dishes. And run a hot tap flush of plain water for a minute after heavy cooking sessions, not to fix anything, just to keep the trap flushed while fats are still suspended in soapy dishwater.
If your kitchen has any history of slow drains, book preventive cleaning in the first week of November. A scheduled $189 to $450 visit in daylight hours beats a $600-plus after-hours emergency on December 27 with a house full of guests. That is not a sales line; it is the calendar talking. Our crews protect kitchens across Coquitlam, North Vancouver and the whole region through the season, and the pre-booked visits are always the calmest jobs of the year.
Condo kitchens deserve a special word before the season starts. In a strata building, your kitchen branch may share a riser with the units above, and one household's holiday grease can slow an entire stack's drainage by spring. If your building has a history of slow kitchen lines, raise it with council before the holidays: a coordinated jetting of the shared lines costs each owner a fraction of what repeated emergency visits cost, and buildings that schedule it every second year rarely see a backup at all. Prevention scales down to one sink and up to forty; the chemistry is identical.
WHEN IT HAPPENS
The Sink Backed Up Anyway: What to Do First
1. Stop adding water. No more taps, and stop the dishwasher mid-cycle if it is running. Everything you add has nowhere to go but up.
2. Try one honest plunge. Block the overflow or second basin with a wet towel, form a real seal, and give ten firm strokes. Grease clogs sit too deep for a plunger most of the time, but it costs two minutes to know.
3. Do not pour chemicals. Caustic cleaners sitting on top of a blockage generate heat and fumes, attack older pipe, and create a hazard for whoever clears the line next. If a tech is coming, the line needs to be chemical-free.
4. Call and describe the pattern. "Kitchen slow for weeks, now full blockage, dishwasher backs up" tells us almost everything: grease in the branch, likely past the trap. Machine cable with a grease cutter head is the first tool, hydro-jetting if the history says the buildup is heavy, camera verification if the result is not a clean, fast, gurgle-free drain when we finish.
5. Ask for the prevention add-on. On any clearing visit we can leave the line treated with an enzyme foam and set you up with the monthly routine. The point of the visit is that it is the last one. Call 604-615-2212 to book a technician or use the emergency page for after-hours dispatch; our plumbing services cover the full range from this clog to whole-line replacement.
FAQ
Grease Clogs and Kitchen Drains in BC: FAQ
Professional kitchen drain cleaning with a machine cable runs $189 to $450 in Metro Vancouver. Hydro-jetting, which scrubs grease off the pipe wall and restores full diameter, costs $450 to $900. After-hours calls add a $150 flat surcharge, disclosed before dispatch. Recurring clogs usually justify jetting over repeated cabling.
Rarely, and it makes things worse long term. Boiling water melts the nearest grease, which travels a few metres into cooler pipe and re-solidifies deeper in your drain line, moving the problem past the trap where tools reach easily. In cast-iron pipe, thermal shock can also crack old corroded sections.
No. Hot soapy water only emulsifies the fat so it travels further before separating, and BC's cold ground re-solidifies it inside your building drain or the city main. The habit creates the same clog in a harder-to-reach spot. Cool it, can it, and green bin it instead.
They are poor tools for grease specifically. Caustic products generate heat and can damage older cast-iron and even soft-metal traps, and they rarely reach a grease plug sitting metres down the line. If a plumber follows after a chemical attempt, the line must be flushed as a hazard before machine work.
Pour fats and oils into a tin can or jar, let them cool and solidify, then scrape the solid into your green bin; grease-soaked paper towels also go in the organics stream. Larger volumes of fryer oil belong at a drop-off depot in a sealed container. Nothing liquid ever goes down a drain.
Yes, for maintenance. Biological treatments use bacteria and enzymes that digest the fat film lining the pipe, and a $15 to $35 monthly bottle keeps a healthy line healthy. They cannot break through an established blockage, so use them after a cleaning, not instead of one.
Repeat clogs mean the cause was never removed: each machine cable pokes a hole through grease but leaves the shelf, which re-closes in weeks. In homes with cast-iron drains, corrosion plus grease compounds it. Hydro-jetting ($450 to $900) plus a camera inspection ($250 to $400) fixes the pattern instead of renting you two good weeks.
