PREVENTIVE PLUMBING
A plumbing maintenance schedule is the least glamorous document in your house and the highest-return one. The arithmetic is blunt: an annual professional tune-up costs $129 to $189, a mid-winter burst pipe in Langley or Maple Ridge costs an emergency call, drywall, carpet and weeks of disruption, and a strata water-damage deductible can run $10,000 to $100,000. Almost every plumbing failure we get called to at 2 a.m. was a $20 part or a ten-minute check six months earlier.
BC's climate makes the calendar genuinely matter. Outflow wind events push Arctic air through the Fraser Valley every winter and freeze pipes that Vancouver's marine climate usually spares. Spring freshet and November rains test sump pumps and drainage. Summer brings Metro Vancouver watering restrictions that change how you use outdoor lines, and fall is the narrow window to winterize everything before the first hard frost. This schedule follows our region's actual rhythm, not a generic checklist written for somewhere it never rains.
Bookmark this page and work through it season by season. Each block lists what to do yourself, what to leave to a licensed plumber, and what it costs in 2026 if you call us: $89 diagnostic credited toward any repair, tune-ups from $129, and a $150 after-hours flat surcharge disclosed before dispatch, day or night, anywhere from Vancouver to Abbotsford.
DECEMBER TO FEBRUARY
Winter Plumbing Maintenance: Survive the Outflow Freezes
Metro Vancouver's cold snaps are short but sharp, and they arrive on outflow winds that funnel cold air down the Fraser Valley through Abbotsford, Langley, Maple Ridge and the North Shore foothills. Pipes fail in predictable places: crawlspaces, garages, attics, and runs along exterior walls, especially where a renovation moved plumbing outside the heated envelope. Water supply lines freeze overnight when cold air reaches them; they burst or split when the water inside expands, and the damage lands the moment they thaw.
Do this before the first forecast of snow or Arctic outflow: insulate exposed supply lines with foam sleeves, a dollar or two per metre at any hardware store; seal the drafts that feed cold air to those pipes with expanding foam or batts; disconnect any hose still on a bibb, because a frozen hose backfills and splits the pipe inside the wall; and know exactly where your main shutoff is. During an outflow event, open the cabinet doors under sinks on exterior walls so house heat reaches the pipes, and let susceptible taps run a pencil-thin stream overnight, which costs pennies of water against thousands in damage.
If you travel in winter, set the heat no lower than 15 degrees, shut the main water valve, and open a low tap to drain pressure. Ask a neighbour to walk the house every few days. A pipe can burst five minutes after you leave or five days; an empty house with the water off turns either event into a dry discovery instead of a flooded one. For the full emergency sequence, read our guide to the first 60 minutes after a burst pipe; it is the one article we ask every customer to read before December.
Winter is also peak hot water season, with longer showers and guests. Watch the tank for rumbling (sediment), rusty tint at hot taps, or water at the base, and act early; the details are in our companion piece on extending water heater lifespan in BC. A tank that dies on December 28 is an after-hours replacement, and after-hours always costs more than Tuesday at 10 a.m.
Give the garage and mechanical room their own five minutes before the first freeze. Water heaters and pressure tanks parked in unheated garages in Surrey and Langley face the same cold as the car beside them, and the pipe nipples at the top of the tank are usually the coldest plumbing in the house. Close the gap under the garage door, wrap exposed runs, and if the space dips well below zero on outflow nights, a small safe garage heater or an insulated tank blanket bought for $30 to $60 does the rest. Condensate lines from high-efficiency furnaces freeze in the same events, so confirm the termination is clear and sloped.
Pro tip: the coldest pipe in your house is usually the one nobody thought about: the kitchen sink on an exterior wall with a drafty sill, the bar fridge line through the garage, or the guest bathroom added over a cantilevered floor. Put your hand on the pipe during the first cold snap. If it is cold to the touch, it is a candidate for insulation tonight.
MARCH TO MAY
Spring Plumbing Maintenance: Test What Winter Stressed
Spring in BC is a stress test in two directions at once: snowmelt raises the water table while April and May rains hammer the drainage. Your plumbing schedule for the season has one star and a supporting cast.
Test the sump pump before the rains, not during. Homes in low-lying parts of Langley, Maple Ridge, Delta and Pitt Meadows depend on sump systems through freshet, and pumps fail in three predictable ways: the float sticks, the impeller jams with grit, or the check valve fails and the pit refills in a loop. The test takes five minutes: pour a bucket of water slowly into the pit, watch the float rise, confirm the pump starts, runs, and shuts off cleanly, then check the exterior discharge line is flowing well away from the foundation and not frozen or crushed. A pump that cycles oddly or hums without moving water needs service immediately; a replacement pump installed before the wet season runs $600 to $1,600, and our sump pump installation cost guide covers the options.
Do the first-turn-on audit of outdoor faucets. In late April, walk every hose bibb: hold your thumb or a gauge over the spout, open the valve and feel for strong pressure, then watch the wall below and inside for dampness in the first minute. A split pipe from a hose left on all winter often shows up exactly here, as a stain, a bulge in drywall, or water in the crawlspace. Repairs caught now are small; caught in July, they have grown a mould colony.
Then the supporting cast: check gutters and downspouts so roof water discharges at least two metres from the foundation; inspect under every sink and behind the toilet for the small weeps that winter's dry air hid; exercise the main shutoff a quarter turn each way so it does not seize; and if the house has an irrigation system, have the backflow preventer tested and certified if required by your municipality, a $100 to $200 service usually due before summer activation.
JUNE TO AUGUST
Summer Plumbing Maintenance: Restrictions, Irrigation and the Easy Repairs
Summer is when Metro Vancouver's water restrictions reshape outdoor use, typically Stage 1 from mid-May with morning-only lawn sprinkling, and it is the season of cheap, dry, comfortable plumbing work. Use it.
Walk the irrigation while it runs. Mist at a broken head, a greener stripe across the lawn, or a hiss under a driveway all point to leaks that dump water and money all season. Compare your metered usage to the same month last year; an unexplained jump in June is almost always an outdoor leak, since indoor habits barely change.
Replace washing machine hoses. Rubber hoses have a five-to-seven-year life, and the failure mode is spectacular: a burst hose on a second-floor laundry floods everything below while you are at work. Braided stainless hoses cost $30 to $80 the pair and fifteen minutes to swap, ours or yours. This is the highest value-per-dollar task on the entire annual schedule.
Run the toilet dye test. Ten drops of food colouring in the tank, wait fifteen minutes without flushing, and any colour in the bowl means the flapper is passing water, which is a silent 20 to 100 litres a day. A $20 to $60 flapper fixes it; do it while the tank is easy to work in and the house is not closed up for winter.
Plan the projects that need dry weather and open windows: repipes, bathroom rough-ins, water heater replacements, anything that shuts water off for hours. Book in summer and you get scheduling flexibility and none of the winter premium urgency; our 2026 plumber cost guide for Vancouver explains how job timing moves pricing.
SEPTEMBER TO NOVEMBER
Fall Plumbing Maintenance: Winterize Before the First Hard Frost
Autumn is the season that decides whether winter is a non-event or a claim. Everything on this list should be finished by Halloween, which is our standing deadline for the Fraser Valley and a safe one anywhere in Metro Vancouver.
Disconnect and drain every hose
Hoses left attached let water sit against the bibb valve, freeze, and split the pipe inside the wall. Drain coiled hoses and store them; shut off and drain any separate isolation valve for exterior lines if your home has one.
Flush the water heater
Drain several litres, or the full tank, before the heavy-use season. Sediment insulates the burner, lengthens heating cycles and quietly shortens tank life. A professional flush with safety checks runs $129 to $189.
Clean the kitchen drain before the holidays
Thanksgiving and December cooking load the line with grease. A pre-season cleaning or enzyme treatment in early November is the cheapest insurance against the year's busiest emergency week.
Clean aerators and showerheads
Soak faucet aerators and showerheads in vinegar overnight to clear flow-restricting scale. Metro Vancouver's soft water makes this a quick job compared with hard-water cities, but debris still accumulates.
Check the pressure and expansion tank
Screw a $20 gauge on a hose bibb: healthy is 40 to 60 psi. Tap the expansion tank near the water heater: hollow sound on top, firm on bottom means it is working. We fold both checks into every tune-up.
Book the pro visit
Autumn is our inspection season because everything can be verified before winter. A $129 to $189 tune-up covers the tank, pressure, valves, drains and a written condition report you can hand to your insurer.
If you want the deep version of the drain-side story, including hydro-jetting and camera work for older homes, our drain cleaning before winter guide pairs with this checklist as the wet-season preparation plan.
EVERY MONTH
The 10-Minute Monthly Plumbing Checklist Every BC Homeowner Can Do
Between seasons, one monthly lap of the house catches problems at their smallest. It requires a flashlight and ten minutes, and it outperforms every gadget on the market.
1. Under every sink, with the flashlight. Look for water stains on the cabinet floor, green corrosion on copper or brass, and damp at the trap joints. Supply lines and trap washers fail slowly; the cabinet tells you weeks in advance.
2. Around the toilet base and behind it. Dark grout, a soft floor, or a ring at the bowl base means the wax ring or the flange is failing. Rock the bowl gently; any movement deserves attention.
3. The meter leak test. With everything off, including the ice maker and any humidifier, watch the meter's small leak indicator for two minutes. Movement means a leak somewhere; systematic shutoffs of the hot tank, irrigation and fixture stops will localize it.
4. Water heater scan. Rust streaks at the base, condensation on a gas tank in a damp Burnaby basement, or corrosion at the pipe nipples are all early flags. Rumbling during recovery is sediment asking for a flush.
5. Washing machine and dishwasher connections. Feel the hoses for bubbles or soft spots, check the drain hose is seated, and look under the machines if you can. Braided hoses should look tight and dry.
6. Read your water bill against last year. Metered homes in Vancouver, Surrey and Coquitlam get a consumption graph on the utility portal. A slow, steady rise with no habit change is the classic signature of a hidden leak, and catching it one month in instead of six is the difference between a repair and a restoration project.
THE PRO VISIT
What Our Annual Plumbing Tune-Up Actually Covers ($129-$189)
The professional visit is the backbone of the schedule. Once a year, a licensed BC Home Service plumber spends sixty to ninety minutes verifying the systems you cannot see from the outside, and the checklist is the same one we use on our own homes.
| Check | What we look for | If it fails |
|---|---|---|
| System pressure test | 40-60 psi at a hose bibb | PRV adjustment or replacement, $450-$800 |
| Water heater flush and inspection | Sediment, anode condition, TPR valve, strapping | Anode replacement $180-$350; see our tank guides |
| Fixture and angle stop exercise | Stops under sinks and toilets turn and hold | Stop replacement, $120-$250 each |
| Toilet fill and flapper test | No phantom running, clean shut-off, no leak at base | Flapper or fill valve, $150-$300 installed |
| Visible leak and corrosion walk | Copper condition, traps, braided lines, meter area | Quoted repairs before they become claims |
| Drain flow survey | Every fixture drains fast, no gurgle, no odour | Cleaning $189-$450, jetting $450-$900 |
| Expansion tank check | Correct pre-charge, no waterlogging | Replacement, $250-$450 |
| Written condition report | Photos, readings, priorities for next year | Yours to keep, useful for insurers and buyers |
Customers in strata buildings should keep the report in their owner file. When a neighbour's insurance claim asks who caused what, a dated inspection showing your suite clean is the strongest document you can hold. To book the visit, use the online booking page or call 604-615-2212; the $89 diagnostic credit applies if any repair follows.

Older BC Homes: Poly-B, Galvanized Steel and Cast Iron on the Same Schedule
A maintenance schedule for a 2018 build in East Cambie is a short document. For the region's older housing stock, three materials change the plan, and knowing which one your home has is worth an hour in the crawlspace.
Poly-B (polybutylene), roughly 1978 to 1995. The grey plastic pipe runs through tens of thousands of homes in Surrey, Langley, Coquitlam and the Fraser Valley. It fails at fittings and under sustained pressure and heat, and BC insurers increasingly decline or surcharge it. If you have poly-B, the maintenance answer is honest: monitor closely, keep pressure at or below 50 psi, and budget for a PEX repipe, $6,000 to $15,000 for most homes. Do not let anyone sell you spot repairs as a strategy.
Galvanized steel, pre-1960s. East Vancouver, New Westminster and North Vancouver character homes often still carry galvanized supply lines. They rust from the inside, shedding iron into drinking water and choking flow; the first symptom is pressure that drops when two fixtures run. The fix is replacement of the remaining galvanized runs with copper or PEX, done in stages if budget requires, and the rusty-water symptom alone is worth a professional look to rule out the water heater's anode as the cause.
Cast-iron drains, pre-1970s. Cast drains last 50 to 100 years but corrode to a rough interior that grabs grease and roots at every joint. On this schedule, cast-iron homes get a professional drain flow check every year and a camera inspection every few years, because a slow drain in cast is a pipe announcing its retirement. Our guides to sewer camera inspections and the region-specific hot water tank pricing in Vancouver cover the two replacements older homes face most.
Buying an older home? Fold a plumbing inspection into conditions, and ask specifically about pipe materials, water pressure, the drain's interior condition and the age of the tank. The $250 to $400 cost of scoping a drain has saved more buyers in New Westminster than any fresh coat of paint ever will.
Condo and townhouse owners run a leaner version of the same schedule. Your in-suite list is identical: sinks, toilets, the water heater if you have your own, the washing machine hoses, and the monthly meter test where metering allows. The building-side items, risers, main shutoffs, sump systems and backflow devices, belong to the strata, so your job is to know who to call and to raise plumbing questions at annual general meetings rather than assume someone else has. A five-minute question in March about when the building last exercised the main valves is cheaper than discovering in November that nobody has touched them since the 1990s.
FAQ
BC Plumbing Maintenance Schedule: FAQ
Once a year by a licensed plumber, $129 to $189 for a full tune-up with pressure, tank, drain and valve checks, plus your own ten-minute monthly walk of sinks, toilets, the meter and the water bill. Homes with poly-B, galvanized pipe or cast-iron drains benefit from annual drain flow checks too.
Inspect under every sink and around each toilet base with a flashlight, run the two-minute meter leak test with all fixtures off, scan the water heater for rust streaks or rumbling, feel washing machine hoses for soft spots, and compare your water bill with the same month last year. Total time: about ten minutes.
Disconnect and drain hoses by Halloween, and shut any isolation valve feeding exterior lines if your home has one, before the first hard frost. Frost-free bibbs still need hoses removed because a connected hose holds water against the valve. First outflow cold snaps often arrive in November in the Fraser Valley.
Keep the heat at 15 degrees or higher, shut the main water valve, open a low tap to relieve pressure, insulate any exposed pipes in the crawlspace or garage, and arrange for a neighbour to walk the house every few days. For short trips during a cold snap, open cabinet doors under exterior-wall sinks so heat circulates.
BC Home Service charges $129 to $189 depending on home size and water heater type, covering pressure testing, a tank flush and inspection, angle stop exercise, drain flow survey, expansion tank check and a written condition report. The $89 diagnostic fee is credited toward any repair that follows within the visit.
Yes. Polybutylene installed from roughly 1978 to 1995 across Surrey, Langley and Coquitlam fails at fittings and under sustained heat and pressure, and many insurers now decline or surcharge it. Keep pressure at or below 50 psi, monitor closely, and budget $6,000 to $15,000 for a PEX repipe rather than repeated spot repairs.
Before the April rains, slowly pour a bucket of water into the pit, confirm the float rises, the pump starts and then shuts off cleanly, and check the exterior discharge line flows freely well away from the foundation. A pump that cycles oddly or hums without moving water needs service now; replacements installed run $600 to $1,600.
