Plumbing & Drain FAQs

Book online through our Booking page or call 647-784-8448 for same-day or after-hours dispatch across Toronto, Etobicoke, North York, Scarborough, York, Mississauga, and Burlington.

Tell us what's happening (backup, leak, no hot water, sewage, etc.), your postal code, and whether anything is actively flowing or contained.

Photos help — even one phone snap of the fixture or the source area lets the dispatch tech roll the right truck.

Yes — same-day and after-hours dispatch is standard across Toronto and the GTA. Active leaks, sewage backup, no-water-in-winter, gas smell, and basement flooding are real emergencies and we prioritize them.

After-hours premium typically runs $80–$200 over standard daytime dispatch in 2026; the call-out fee, surcharge, and hourly are quoted separately so you can compare apples to apples.

Diagnostic / minimum service-call: $120–$220 (often credited toward the repair). Master plumber hourly: $150–$220/hr; apprentice-supervised crew: $110–$165/hr.

Common scopes: faucet repair $180–$320, toilet replacement $450–$900, drain snake $189–$650, hydro jet $400–$1,400, hot water tank swap $2,200–$4,200, backwater valve install $2,800–$4,800 ($1,250 City rebate), sump pump install $1,400–$6,500 ($1,750 City rebate), sewer line repair $2,500–$25,000+.

City of Toronto plumbing permit fees: $190–$850 depending on scope. We pull permits as part of any permit-required job.

Tornado Plumbing & Drains has been serving Toronto and the GTA since 2016 with 1,200+ completed jobs, 180+ five-star Google reviews, and 400+ HomeStars reviews (Best of 2019–2025).

Yes — every job we complete is backed by a 25-year workmanship warranty. The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.

Manufacturer warranties on parts (water heaters, valves, fixtures, pumps) are separate and pass through to the homeowner per the manufacturer terms.

We diagnose first — pipe condition, pressure, access, fixture function — and explain what we found in plain language with practical options and a written quote before any work starts.

After approval, we complete the work, verify the result (flow, drainage, operation, leak-free), photograph the install for the documentation file, and clean the area before we leave.

Active emergencies in Toronto and the immediate GTA: typically 60–90 minutes from dispatch to arrival. Major-storm event days can run longer; we triage by severity (active sewage > active burst > contained > non-active).

Non-emergency scheduling is usually within 24–48 hours. Book online for the fastest path.

It depends on what's clogging it. Hot water + dish soap clears early kitchen-grease films. Plunger handles toilets; manual snake clears hair and soap scum in shower drains. Avoid chemical drain cleaners — they damage older Toronto pipe (cast iron, ABS) and rarely fix the root cause.

When DIY doesn't hold or the line is older than ~30 years, we inspect-first with a camera, then match the cleaning method to actual pipe condition (snake $189–$650, jet $400–$1,400, descaling $900–$2,400).

Snake is right for soft, isolated clogs (paper, hair, fresh grease). Jet is right for set grease, mineral scale, root mats, and recurring slowdowns where snaking has been done multiple times without lasting results.

If you've been snaked within the past 12 months on the same line and it's slow again, jetting is what actually fixes it. Severely deteriorated cast iron should be camera-inspected first — high-pressure jetting can fail fragile pipe walls.

Recurring slowdown at the same fixture within 6–12 months is no longer a clog — it's a line-condition issue. Most common causes in Toronto: root intrusion through clay-lateral joints (~38% of our inspections), grease coating in kitchen lines (~11%), bellies/sags (~14%), cracked clay (~22%).

A camera inspection ($250–$650) is the only objective way to confirm what's wrong and choose the right repair scope.

Keep people and pets out of the affected area — sewage is Category-3 black water under the IICRC S500 industry standard. Stop running ANY water in the home (no flushing, no sinks, no laundry). Photograph everything for insurance. Call us — 647-784-8448.

After the immediate emergency: most Ontario insurers now require an installed backwater valve and/or sump pump for sewer-backup claims to pay. The City of Toronto Basement Flooding Protection Subsidy covers up to $6,650 of that prevention work (valve $1,250 + sump $1,750 + weeping-tile disconnect $3,400).

Almost certainly because your home is on Toronto's combined-sewer system (about 25% of the city, concentrated in older central, east, and west neighbourhoods). The combined system carries both sanitary and storm water; intense rain surcharges it and pushes back through the path of least resistance — your basement floor drain.

It's a system-level problem, not your line. The fix is a backwater valve on the sanitary lateral ($2,800–$4,800 install, $1,250 City rebate, prevents ~95% of sanitary back-flow).

Acoustic listening, thermal imaging, tracer-gas (helium/hydrogen), and pressure testing — usually a combination on the same visit. Most Toronto hidden leaks are located in 30–90 minutes without tearing up drywall.

Catching a hidden leak early often means a $400 spot repair instead of $8,000+ in mould remediation. Slab leaks waste 30+ litres per hour undetected; the water bill often shows it before any visible damage.

Spot repair (~$1,800–$4,500) makes sense for a single-section failure on otherwise sound copper or HDPE. Full replacement ($4,500–$14,000 trenchless or open-cut) makes sense for galvanized lines (corrodes throughout), lead service lines, or 50+ year copper at end-of-life.

Lead service replacement: the City of Toronto pays for the public-side replacement when the homeowner replaces the private side concurrently — a meaningful saving. Free water-lead testing through Toronto Public Health.

Possibly, if your home was built before 1955 (some up to 1965). Toronto Public Health offers free water-lead testing for any homeowner. The City also maintains an online Lead Service Map by address.

Health Canada drinking-water guideline for lead: 0.005 mg/L max. The City of Toronto's Priority Lead Water Service Replacement Program covers public-side replacement at no cost when scheduled with the homeowner-side install.

If it won't fully close, leaks at the stem, shows visible corrosion, or is older than ~20 years. Older gate valves seize within 15–25 years and are useless when you actually need them. Replacement with a quarter-turn ball valve runs $280–$650 in Toronto — the cheapest insurance any homeowner can buy.

Average burst-pipe damage when the main can't be shut off in 5 minutes: $8,000–$25,000 in finishes. We test the shutoff free on every diagnostic visit.

Yes. Standard 3-piece rough-in includes the drain, waste, and vent (DWV), supply rough, and ejector basin and pump if gravity to the main stack isn't possible. Toronto plumbing permit and inspection are mandatory.

Cost: $3,500–$6,500 if builder rough-in stubs are present, $5,500–$9,500 if a new ejector pit is required, $7,500–$14,000 for full slab break-in. We pull every required permit and meet the inspector.

Recurring backups (more than once in 12 months), buying or selling a property (pre-purchase due diligence), post-major-backup confirmation that cleaning will hold, planned renovation that touches underground plumbing, or insurance documentation of cause-of-loss.

Cost in Toronto: $250–$650 typical; $500–$900 with sonde locate. Includes recorded video, written PACP-coded report, photo stills with footage time-codes — usable for insurers, lawyers, and future plumbers.

From our 1,200+ Toronto inspections: root intrusion ~38% (clay-lateral joints), cracked clay laterals ~22%, bellies/sags ~14% (standing water), grease coating ~11% (kitchen lines), offset joints ~6%, scaling ~5%.

Clay laterals (pre-1970) are root-prone. Cast iron (1950s–80s) rots from the bottom (channel rot) and develops tubercular scale. ABS (1980+) is more durable but pulls at joints when soil settles.

Yes. Spot repair ($2,500–$5,500), trenchless lining/CIPP ($6,000–$14,000), full replacement ($8,000–$25,000+ depending on length, depth, and method). Camera footage with PACP coding decides the right scope.

Trenchless preserves driveway, lawn, and hardscape on most Toronto properties. Open-cut is required when the line is severely collapsed, shallow, or shared with a neighbour. Toronto plumbing permit and Ontario One Call locate are mandatory before any sewer work.

CIPP lining cures a resin liner inside the existing pipe (preserves diameter, ~$200–$330/ft, works in 4″+ host pipe). Pipe bursting pulls a new HDPE pipe through the old, fracturing the old outward (can upsize, ~$280–$420/ft, works in any host material).

Lining is faster and least disruptive when the host pipe is intact-ish. Bursting is the right call for severely deteriorated pipe or when upsizing from 4″ to 6″ for capacity.

The Basement Flooding Protection Subsidy was expanded May 1, 2026 to provide up to $6,650 per property: $1,250 backwater valve + $1,750 sump pump system + $3,400 weeping-tile disconnect. Eligible work must be completed on or after November 12, 2025 by a licensed contractor with permit and passed inspection.

Homeowner pays for the install, then submits the documentation package (invoice, photos, model/serial numbers, permit number, signed inspection card) to the City for reimbursement. Tornado provides the package as standard.

$2,800–$4,800 gross for a mainline normally-open valve installed in a typical finished basement (saw-cut, dig, install, restore, permit, inspection). The City rebate covers $1,250, bringing typical net to $1,550–$3,550.

Mainline (full-port) valves protect every drain in the home — preferred over single-fixture branch valves. City data shows installed backwater valves prevent ~95% of sanitary back-flow events during combined-sewer surcharge.

Yes for any home with a finished basement. Major storms in southern Ontario routinely take out the power grid for hours — exactly when the primary pump can't run. Average Toronto basement flood claim: ~$43,000 (Insurance Bureau of Canada). Battery backup retrofit: $1,200–$2,400.

Most Ontario insurers reduce the water-damage premium $80–$200/yr after documented prevention install — payback in 5–8 years. AGM batteries last 3–5 years; lithium 8–10 years.

$2,200–$3,200 for a 40-gal atmospheric-vent gas tank (most common). $2,800–$4,200 for 50–60-gal power-vent. $1,800–$2,800 for electric. $4,500–$6,500 for tankless conversion including venting and gas-line upgrade where required.

Gas work requires a TSSA-licensed gas-fitter (G2 minimum). Modern installs include expansion tank, drip pan if above finished space, and full-port shutoffs as code-required upgrades.

Tankless lasts 18–22 years (vs 10–15 for tank), saves 25–35% energy for low-to-moderate use households, and never runs out — but costs $2,000–$3,500 more upfront and may require a 3/4″ gas-line upgrade in older homes.

Tank costs less ($2,200–$4,200), installs in 3–4 hours, and recovers well for high-simultaneous-demand households. Both require TSSA-licensed install in Ontario.

Yes — Toronto water hardness is 120–140 mg/L CaCO₃ (moderately hard), and manufacturer warranty terms (Rinnai, Navien, Noritz, Rheem) require documented annual descaling to keep heat-exchanger coverage in force.

Cost: $220–$380 with isolation valves; $400–$650 if valves need to be installed during the visit. Skipping years means heavier scale, 15–25% efficiency drop, and potential heat-exchanger failure outside warranty ($1,200–$2,400 to replace).

Yes — full commercial scope: drain cleaning, hydro jetting, grease trap install + service, backflow testing under the City's Cross-Connection Control Program, tenant fit-out rough-in, and scheduled maintenance contracts.

Off-hours dispatch (10 PM–6 AM) is standard for restaurants. Compliance documentation (date, scope, technician license, hauler manifest for grease) is provided for every visit — required under Toronto Sewer Use Bylaw (Ch. 681) and Toronto Public Health food-premises inspections.

Toronto City schedule: typically 30 days for high-volume kitchens (150+ covers/day, deep-fry, heavy grease), 60–90 days for moderate, longer for low-volume cafes. Sewer Use Bylaw caps grease/oil discharge at 100 mg/L; missing or undersized cleaning gets restaurants over the limit and triggers fines.

Cost: $280–$480 per under-counter pump-out; $450–$900 per exterior interceptor pump. Quarterly contracts reduce per-visit cost 20–35% vs ad-hoc.

Yes — Toronto's Cross-Connection Control Program requires annual testing of all installed backflow preventers (RPZ for high-hazard, DCVA for low-hazard, PVB for irrigation) by a certified tester (CSA B64.10 standard).

Cost: $180–$320 single device, $140–$250 per device on multi-device same visit. Failed devices require repair or replacement and re-test before compliance can be filed. Missed annual tests trigger City compliance notices.
