Plumbing Questions, Answered

Most GTA plumbers charge between $100 and $200 per hour, plus materials. A typical service call runs $150 to $350 depending on the job. ProFlow provides free written estimates before any work starts, so you always know the cost upfront.

Yes. Ontario law requires anyone performing plumbing work to hold a valid licence regulated by the Technical Standards and Safety Authority (TSSA). Unlicensed work can void your home insurance and create safety hazards. Every ProFlow technician is fully licensed and insured.

Your main shut-off valve is usually near the water meter, often in the basement where the water line enters your home. Turn the valve clockwise (or perpendicular to the pipe for a ball valve) to stop all water flow. Knowing this location before an emergency can save thousands in water damage.

We recommend a professional plumbing inspection every 2 years for most homes, or annually for homes older than 30 years. An inspection catches small problems — like slow leaks or corroding pipes — before they turn into expensive emergencies. Contact ProFlow to schedule yours.

Hard water contains high levels of calcium and magnesium, which leave white deposits on fixtures and reduce the lifespan of water heaters. Much of the GTA has moderately hard water. A water softener system can protect your plumbing and improve water quality — ask ProFlow about installation options.

A sudden spike in your water bill usually points to a hidden leak — often a running toilet, a dripping faucet, or a leaking pipe behind a wall. A single running toilet can waste over 750 litres of water per day. ProFlow can perform a leak detection inspection to find the source.

Homeowners can perform minor repairs like replacing a faucet washer or tightening a connection, but anything involving drain or vent modifications, water supply rerouting, or gas lines requires a licensed plumber and a permit under the Ontario Building Code.

Check for a valid Ontario plumbing licence, proof of liability insurance (at least $2 million), WSIB coverage, and online reviews. A reputable plumber provides written quotes, explains the work clearly, and never pressures you into unnecessary repairs. ProFlow meets all these standards.

Most home insurance policies cover sudden, accidental water damage like a burst pipe, but not gradual issues like slow leaks or wear-and-tear. Maintenance-related problems — such as a corroded pipe that's been leaking for months — are typically excluded. ProFlow provides detailed documentation to support insurance claims when covered events occur.

Professional drain cleaning in the GTA typically costs $150 to $450 depending on the location and severity. A simple kitchen or bathroom drain clearing starts around $150, while main sewer line cleaning starts at $250. ProFlow provides a fixed quote before starting any work.

Recurring clogs usually indicate a deeper problem — tree root intrusion, a bellied (sagging) pipe, or heavy grease buildup inside the line. A plunger or store-bought snake only clears the surface blockage. A camera inspection reveals the root cause so we can fix it permanently.

No. Chemical drain cleaners generate heat and corrosive reactions that damage pipes over time, especially older copper, cast iron, and ABS systems. They also pose health risks and harm the environment. Professional mechanical cleaning is safer and more effective long-term.

We recommend professional drain cleaning every 18 to 24 months as preventive maintenance. Homes with mature trees near sewer lines, older plumbing, or a history of clogs may benefit from annual service. Regular cleaning prevents emergency backups.

Hydro jetting uses high-pressure water (up to 4,000 PSI) to scour the inside of drain pipes clean. It removes grease, mineral scale, tree roots, and debris more thoroughly than snaking alone. It's the gold standard for drain cleaning and is safe for most pipe types when done by a professional.

Kitchen sinks clog primarily from grease, food particles, and soap scum building up inside the drainpipe over time. Running hot water and dish soap after each use helps, but once a clog starts forming, it needs professional cleaning to fully clear the buildup.

Once roots find a crack or joint in your sewer line, they'll keep coming back. Options include periodic root cutting (every 12 to 18 months), chemical root barriers, or a permanent fix like trenchless pipe lining that seals the line against future intrusion. Contact ProFlow to discuss the best approach for your property.

Sewer odours usually come from a dried-out P-trap (the U-shaped pipe under your sink), a cracked drain line, or a blocked vent stack on your roof. Running water in unused drains once a month keeps the trap filled. If the smell persists, call ProFlow — it could indicate a more serious venting issue.

A drain snake physically breaks through a clog, creating a narrow channel for water to flow. Hydro jetting cleans the entire interior of the pipe wall, removing all buildup. Snaking is faster for simple blockages; hydro jetting is more thorough for recurring problems or heavy buildup.

A traditional tank water heater lasts 8 to 12 years, while a tankless unit can last 15 to 20 years with proper maintenance. If your tank is over 10 years old and showing signs like rusty water, strange noises, or reduced hot water, it's time to plan a replacement before it fails completely.

Tank heaters cost less upfront ($1,500 to $2,200 installed) and work well for predictable demand. Tankless units cost more ($3,500 to $6,500 installed) but deliver endless hot water, save up to 30% on energy, and last nearly twice as long. The best choice depends on your household size and hot water usage patterns.

A household of 1 to 2 people typically needs a 40-gallon tank or a 140,000 BTU tankless unit. Families of 3 to 4 need a 50 to 60-gallon tank or a 180,000 BTU tankless unit. Larger households may need a 75-gallon tank or a 199,000 BTU unit. ProFlow sizes your system based on actual peak demand during a free in-home assessment.

Rusty hot water usually means the anode rod inside your tank has corroded and the tank itself is starting to rust. This is a sign the unit is nearing end-of-life. A plumber can replace the anode rod to extend the tank's life, but if the tank body is corroded, replacement is the safer option.

A standard 50-gallon tank water heater replacement in the GTA runs $1,500 to $2,200, including removal of the old unit, installation, and permits. Tankless installations start around $3,500. ProFlow provides detailed written quotes with no hidden fees — contact us for a free estimate.

If your water heater is under 6 years old and the repair costs less than half of a replacement, repair usually makes sense. For units over 8 years old, or those needing repeated repairs, replacement is more cost-effective. ProFlow will give you an honest recommendation based on your unit's age and condition.

Yes. Flushing the tank to remove sediment, checking the anode rod, and testing the pressure relief valve once a year can extend your water heater's life by 3 to 5 years. Most homeowners skip this, which is why tanks often fail early. ProFlow offers annual maintenance plans starting at $99.

Warning signs include lukewarm water that used to be hot, rusty or metallic-tasting water, rumbling or popping noises from the tank, visible leaking around the base, and rising energy bills. If you notice any of these, schedule an inspection before the unit fails completely.

Yes. Enbridge Gas offers rebates of up to $1,000 for qualifying high-efficiency water heaters, including tankless models. Some GTA municipalities also run additional incentive programs. ProFlow helps you identify available rebates and provides the documentation you need to apply.

A plumbing emergency is any situation that could cause immediate property damage or health risks: burst pipes, active flooding, sewer backups, gas leaks, or a complete loss of water. If water is spreading or you smell gas, call ProFlow's 24/7 emergency line immediately at (416) 555-1234.

ProFlow's average emergency response time across the GTA is 45 minutes. In most areas, we arrive within 30 to 60 minutes. Active flooding and gas leaks receive our highest priority dispatch. Our trucks are fully stocked to resolve most emergencies in a single visit.

Yes — shutting off the water is the single most important thing you can do during a plumbing emergency. Locate your main shut-off valve (usually near the water meter in your basement) and turn it clockwise. This stops water flow to your entire home and limits damage while you wait for help.

ProFlow's emergency service call starts at $250, which includes the first hour of labour. We don't add surcharges for nights, weekends, or holidays. You'll receive a clear quote for any additional work before we proceed, so there are never surprise charges.

Shut off the main water valve immediately, then call ProFlow at (416) 555-1234. Open faucets to drain remaining water from the lines. If the burst is near electrical panels, shut off power to that area. Move valuables away from the water. Our emergency team arrives in 45 minutes on average.

Most home insurance policies cover sudden, accidental water damage like a burst pipe. ProFlow documents all emergency work with detailed photos, reports, and itemized invoices that insurance companies require. We can also communicate directly with your adjuster.

Licensed plumbers in Ontario are qualified to work on gas piping. If you smell gas (a rotten egg odour), leave your home immediately, don't use electrical switches, and call from outside. Then call ProFlow — we carry electronic gas leak detectors to locate and repair gas line issues safely.

Water expands by about 9% when it freezes, generating enormous pressure inside pipes. Pipes in unheated areas — exterior walls, crawl spaces, garages, and uninsulated basements — are most vulnerable. GTA winters regularly produce the sustained freezing temperatures needed to burst copper and PVC pipes.

A basic bathroom refresh (new fixtures, paint, and hardware) takes 1 to 2 weeks. A mid-range renovation with new tile, vanity, and tub surround takes 3 to 4 weeks. A full gut-and-rebuild with layout changes takes 6 to 8 weeks. ProFlow handles the plumbing scope on a schedule coordinated with your general contractor.

Yes, if the renovation involves moving or adding plumbing fixtures, altering drain or vent piping, or changing water supply lines. The City of Toronto requires a plumbing permit under the Ontario Building Code for these changes. ProFlow handles the full permit process — application, inspection scheduling, and sign-off.

According to the Appraisal Institute of Canada, a well-executed bathroom renovation typically recoups 60 to 70 percent of its cost at resale. A mid-range renovation ($15,000 to $25,000) tends to deliver the best return. Luxury finishes add enjoyment but recover a smaller percentage.

A basic refresh runs $5,000 to $12,000. A mid-range renovation with new tile, vanity, and fixtures costs $15,000 to $35,000. A full luxury renovation with layout changes can exceed $50,000. The plumbing portion alone typically runs $1,500 to $8,000 depending on scope.

Absolutely. Relocating drains, water supply lines, and venting for a new layout is one of our specialties. Moving a toilet requires relocating the 3-inch drain line, which is the most complex part. ProFlow handles all the permitting and inspections required for plumbing relocations.

WaterSense-certified toilets and low-flow showerheads save water without sacrificing performance, and they qualify for some municipal rebates. A quality single-handle faucet with ceramic disc cartridges will last 10+ years. Avoid the cheapest fixtures — mid-range brands like Moen, Delta, and Kohler offer the best balance of quality and cost.

All at once is usually more cost-effective because trades only need to mobilize once, and the plumbing rough-in happens before finishes go in. Phased renovations are possible but typically cost 15 to 20 percent more overall due to repeated setup and potential rework. ProFlow can help you plan either approach.

Yes, ProFlow regularly partners with GTA general contractors on bathroom and kitchen renovations. We coordinate our rough-in and fixture installation schedules with their timelines to minimize delays and ensure seamless integration with other trades.

Walk-in showers are trending for their modern look and accessibility, and they use less water. However, having at least one bathtub in your home is important for resale value, especially for families with young children. A tub-to-shower conversion in a secondary bathroom is a popular compromise.

A complete tankless water heater installation in the GTA runs $3,500 to $6,500, including the unit, labour, and all materials. The main cost variables are the BTU rating, venting length, and whether your gas line needs an upgrade. ProFlow provides a detailed written quote after a free in-home assessment.

Tankless water heaters typically last 15 to 20 years — nearly double the lifespan of a traditional tank. With annual descaling and filter cleaning, some units last even longer. Most manufacturers offer 10 to 15-year warranties on the heat exchanger, the most critical component.

Yes. Tankless units only heat water when you need it, eliminating the standby energy loss of keeping a tank hot 24/7. Most homeowners see 20 to 30 percent savings on the water-heating portion of their gas bill. The savings add up to $150 to $300 per year for a typical GTA household.

A properly sized tankless unit delivers endless hot water — it never runs out. However, there's a limit to how many fixtures it can supply simultaneously. A 199,000 BTU unit can typically handle 3 to 4 fixtures running at once, which covers most households. ProFlow sizes your unit based on your actual peak demand.

Often yes. Tankless units require more gas flow than traditional tanks — typically a 3/4-inch gas line instead of 1/2-inch. If your existing line can't deliver enough gas, we'll upgrade it as part of the installation. This is factored into our quoted price.

Annual descaling with food-grade white vinegar is the most important maintenance task — it removes mineral buildup from the heat exchanger. You should also clean the inlet water filter every 6 months and check the condensate drain for blockages. ProFlow offers annual maintenance plans.

Navien, Rinnai, and Noritz are the top three brands for Canadian installations. Navien offers excellent value with built-in recirculation pumps. Rinnai is known for durability and has the widest service network. Noritz provides commercial-grade reliability. ProFlow installs and services all three.

If your home has a basement and sits on clay soil or near a high water table — which describes much of the GTA — a sump pump is strongly recommended. It's your primary defence against basement flooding during spring thaw and heavy rain events. ProFlow offers free basement assessments to evaluate your risk.

Test your sump pump every 3 months by pouring a bucket of water into the pit until the float triggers the pump. It should activate quickly, pump the water out, and shut off automatically. Test monthly during spring and fall, and always before a forecasted heavy rainstorm.

A basic sump pump replacement costs $800 to $1,200. A new pit excavation with pump installation runs $1,500 to $2,000. Adding a battery backup system costs an additional $600 to $1,000. A complete system with primary pump and battery backup runs $2,500 to $3,000. ProFlow provides free written estimates.

We strongly recommend it. Power outages often coincide with heavy storms — exactly when you need your pump most. A battery backup keeps your sump pump running for 8 to 12 hours without power. For homes with finished basements or valuable items stored below grade, it's essential protection.

A quality submersible sump pump lasts 7 to 10 years with proper maintenance. Pedestal pumps can last longer since the motor stays dry above the water line. We recommend replacing your pump proactively before it fails — a $1,000 pump replacement is far cheaper than a $20,000 flood cleanup.

A continuously running sump pump usually indicates a stuck float switch, a check valve failure (water flowing back into the pit), or an undersized pump that can't keep up with groundwater flow. All three are fixable — contact ProFlow for a diagnosis before the motor burns out.

Sump pumps discharge through a pipe that routes water away from your foundation, typically to a storm drain, dry well, or a graded area of your yard at least 3 metres from the house. Per Ontario building code, sump pumps must not discharge into the sanitary sewer. ProFlow ensures every installation meets local municipal requirements.

Warning signs include discoloured water (brown or rusty), low water pressure, visible corrosion on exposed pipes, recurring leaks, and damp spots on walls or ceilings. Homes built before 1990 with galvanized or polybutylene pipes should be inspected proactively — these materials are prone to failure.

Trenchless technology lets us repair underground pipes without digging up your yard, driveway, or basement floor. We insert a resin-coated liner into the existing pipe, which hardens to form a new pipe inside the old one. It's faster, less disruptive, and often more cost-effective than traditional excavation.

A partial repipe (one bathroom or the main water line) runs $2,000 to $5,000. A full home repipe with PEX costs $8,000 to $15,000 depending on the size of the home and number of fixtures. ProFlow provides a detailed assessment and written quote before any work begins.

Both are approved under the Ontario Building Code. Copper is the traditional standard — durable and long-lasting but more expensive and rigid. PEX is flexible, freeze-resistant, quieter, and 30 to 40 percent cheaper to install. Most GTA homeowners choose PEX for cost savings without sacrificing quality.

Copper water supply pipes typically last 50 to 70 years. However, aggressive water chemistry, poor installation, or soil conditions can cause premature failure through pinhole leaks. If you're seeing green corrosion on exposed copper pipes, schedule an inspection with ProFlow to assess their condition.

Pinhole leaks develop when aggressive water chemistry slowly corrodes the pipe wall from the inside out. Contributing factors include low pH water, high chlorine levels, and dissolved oxygen. They're common in GTA homes with original copper plumbing from the 1970s and 1980s.

Absolutely. A pinhole leak dripping at just one drop per second wastes over 11,000 litres of water per year and can cause extensive mould growth, wood rot, and structural damage behind walls. If you notice unexplained damp spots, musty smells, or rising water bills, call ProFlow for leak detection.

Shut off the main water valve immediately, then call ProFlow at (416) 555-1234 for emergency service. Open faucets to drain remaining water. If the burst is near electrical panels, shut off power to that area. Move belongings away from the water. Our emergency team arrives in 45 minutes on average.

Insulate exposed pipes in unheated areas like garages, crawl spaces, and exterior walls with foam pipe sleeves. During extreme cold, open cabinet doors under sinks on exterior walls and let a thin stream of water trickle from faucets. Keep your home thermostat at 15°C or higher, even when away.

Fall is the best time for a pre-winter inspection — it catches vulnerable pipes before the first freeze. We also recommend inspecting after buying a new home, before starting renovations, and whenever you notice signs like low water pressure, discoloured water, or unexplained dampness.

Yes. Before the first freeze, disconnect garden hoses, shut off the interior valve that feeds each outdoor faucet (called a hose bib), and open the outdoor tap to drain remaining water. This prevents the pipe from freezing and bursting inside your wall, which can cause significant hidden damage.

For trips longer than a few days, shut off the main water valve, set your water heater to vacation mode, and have someone check your home periodically. In winter, keep the thermostat at 15°C minimum to prevent frozen pipes. Consider installing a water leak detector with smartphone alerts for extra peace of mind.

Spring is the ideal time to test your sump pump, check outdoor faucets for freeze damage, inspect exposed pipes for leaks, and schedule a drain cleaning if you have mature trees near your sewer line. Clear debris from your floor drains and run water in unused fixtures to refill P-traps.

Yes. Heavy rainfall can overwhelm storm drains and cause water to back up through basement floor drains, especially in older homes with combined sewer systems. A properly installed sump pump and a backwater valve are your best defences. Contact ProFlow to assess your home's flood risk.

Falling leaves and debris can clog exterior drains and roof gutters, which can lead to foundation water issues. Clear your eavestrough downspouts, check that sump pump discharge lines aren't blocked, and consider scheduling a drain cleaning before winter to remove any summer buildup.
