💡 The Core Principle The most expensive plumbing repairs in BC homes are almost always preventable. Not by major intervention — by consistent, simple habits applied on a regular schedule. The 10 tips below take a combined total of roughly 30 minutes a month to maintain. The water damage, emergency callouts, and pipe replacements they prevent can cost $5,000 to $50,000 to fix. |
Whether you own a new build in Langley or a 1970s character home in Vancouver, your plumbing system needs consistent attention. These 10 habits are the difference between homeowners who spend on emergency repairs and those who don’t.
1. Never Pour Grease Down Your Drains
1 | Never Pour Grease Down Your Drains Cooking grease, fats, and oils solidify as they cool inside drain lines. A single pour seems harmless — but over months and years, grease accumulates in layers on pipe walls, progressively narrowing the bore until flow restricts completely. In BC’s Lower Mainland, grease-blocked kitchen drains are one of the most common causes of residential sewer backups. The fix? Pour cooled grease into a container and dispose of it in the bin. Run hot water and dish soap after washing greasy pots — not instead of proper disposal. For existing grease buildup, professional hydro jetting removes it completely — chemical cleaners do not. |
2. Use Drain Screens in Every Shower and Bathtub
2 | Use Drain Screens in All Shower and Bath Drains Hair is the leading cause of shower and bath drain blockages. A single shower produces enough hair to begin restricting a drain within weeks — particularly in households with long hair or multiple occupants. Drain screens catch hair at the surface before it enters the pipe system, where it combines with soap scum and body oils to form stubborn, adherent blockages that require mechanical clearing. Stainless steel drain screens cost $5–$15 and last years. Clean them weekly — it takes 10 seconds. This single habit eliminates the majority of shower drain blockages entirely. For existing blocked shower drains, our guide on how to unclog a shower drain covers the full process. |
3. Flush Your Water Heater Annually
3 | Flush Your Water Heater Annually Sediment — primarily calcium and magnesium mineral scale — accumulates at the base of your hot water tank every year. In communities with harder water like Abbotsford, Chilliwack, and parts of the Fraser Valley, accumulation is faster. Sediment forces the heating element to work harder, raises energy bills, reduces hot water volume, accelerates corrosion, and shortens tank lifespan. Annual flushing removes sediment before it causes damage: connect a garden hose to the drain valve, open it, and let water run until clear. Also test the TPR valve. If your tank is over 10 years old and showing signs of age, review our guide on when to change your water heater. For replacement, Gator Plumbing handles hot water tank repair and replacement across Metro Vancouver. |
4. Test Your Sump Pump Before the Rainy Season
4 | Test Your Sump Pump Before Every Rainy Season BC’s Lower Mainland receives 1,150–1,500mm of annual rainfall, most of it between October and March. Your sump pump is the primary defence against basement flooding during that period — and if it fails during a major storm, the result is water damage, mould, and emergency extraction costs. Test it every September before the season begins: pour water into the pit until the float rises, confirm the pump activates and discharges correctly, check that the outlet is clear and draining away from the foundation, and replace the battery backup if fitted. A sump pump test takes five minutes. A basement flood takes weeks and thousands of dollars to remediate. If flooding does occur, Gator Plumbing provides 24/7 flood pump-out service. |
5. Know Exactly Where Your Main Shut-Off Valve Is
5 | Know Where Your Main Shut-Off Valve Is In a burst pipe situation, every second of delay adds to the water damage. The main water shut-off valve stops all water flow to the home — but only if you can find it and operate it quickly. In Metro Vancouver and Surrey homes, the main shut-off is typically located where the water service enters the building: at the front foundation wall, in the utility room, or in the crawl space. Find it now, confirm every adult in the household knows its location, and test it once a year by turning it fully off and back on. A valve that hasn’t been operated in years may seize — if yours is stiff or non-functional, have it replaced before you need it urgently. Gator Plumbing handles valve replacement and plumbing repairs across the Lower Mainland. |
6. Check Under Every Sink Monthly for Leaks
6 | Check Under Sinks Monthly for Hidden Leaks Supply line leaks under sinks are among the most common — and most ignored — residential plumbing problems. A slow drip from a compression fitting or a weeping P-trap connection can saturate a cabinet floor and subfloor for months before visible damage appears. Once mould growth has established in a saturated cabinet, remediation costs far exceed the original repair. Once a month, open the cabinet under every sink, look at the floor for moisture or staining, and feel the supply line connections for dampness. Check under the dishwasher, washing machine, and refrigerator ice maker connection too. If you find moisture, call a licensed plumber before it compounds. |
7. Insulate Exposed Pipes Before Winter
7 | Insulate Exposed Pipes Before the First Frost Pipes in uninsulated crawl spaces, garages, exterior wall cavities, and unheated outbuildings are vulnerable to freezing when temperatures drop. In Metro Vancouver, hard freezes are infrequent but do occur — and a single freeze-thaw cycle can crack a supply line that then leaks silently inside a wall. Foam pipe insulation from any hardware store costs $1–$3 per metre and takes an afternoon to install. Wrap all exposed supply lines in unheated spaces before November. Disconnect and drain outdoor hose bibs and shut off their interior valves. Keep cabinet doors under exterior wall sinks open during cold snaps. If a pipe does freeze, our guide on how to thaw a frozen water pipe covers safe thawing methods. |
8. Schedule Perimeter Drain Cleaning Every 3–5 Years
8 | Flush Perimeter Drains Every 3–5 Years The perimeter drain system running around your foundation diverts groundwater during BC’s heavy rainy seasons. Over years, these drains accumulate silt, fine debris, and root infiltration — particularly in older homes with clay tile or Orangeburg pipe. A partially blocked perimeter drain is invisible from the surface until it fails during a major rainfall event and water enters the basement. Professional drain cleaning and camera inspection of the perimeter system every 3–5 years catches blockages and deterioration before they cause flooding. Gator’s professional drain cleaning service covers perimeter lines across Vancouver, Surrey, Burnaby, and Langley. |
9. Stop Using Chemical Drain Cleaners
9 | Stop Using Chemical Drain Cleaners — They Damage Your Pipes Chemical drain cleaners — products like Drano and Liquid-Plumr — use sodium hydroxide (lye) or sulfuric acid to dissolve organic blockages. They work on soft blockages near the drain opening. What they also do: generate significant heat during the chemical reaction, which softens and warps PVC drain lines; corrode older metal pipes, fittings, and rubber seals over repeated use; damage porcelain fixture surfaces; and leave residue that is toxic to municipal sewer systems and septic fields. For a slow drain, use a drain snake or hydro jetting. For recurring blockages, book a camera inspection to identify the underlying cause. Chemical cleaners mask symptoms while accelerating pipe deterioration. |
⚠️ Why Chemical Cleaners Are Worse for Old Pipes In pre-1985 BC homes with cast iron drain stacks, galvanized steel supply lines, or clay tile perimeter drains, repeated chemical cleaner use causes accelerated corrosion at joints and fittings. These pipes already have reduced structural integrity — chemical exposure speeds up the failure timeline significantly. If your home was built before 1985, chemical drain cleaners are particularly harmful. See our full guide on maintaining plumbing in older BC homes. |
10. Get a Camera Inspection Every 3–5 Years for Homes 20+ Years Old
10 | Schedule a Camera Inspection Every 3–5 Years For any home over 20 years old, a professional sewer camera inspection every 3 to 5 years is the single most effective preventive maintenance action available. The camera travels through your drain lines and sewer lateral — revealing root intrusion, pipe bellies, joint separation, corrosion, and Orangeburg collapse that no surface symptom will warn you about until the system fails. Each inspection includes HD footage on USB and a written defect report, giving you documented proof of your system’s condition for insurance, resale, and repair planning. For older homes, our in-depth guide on how plumbing cameras see through water explains exactly what the inspection reveals. Book a camera inspection across Vancouver, Surrey, Burnaby, Coquitlam, and the Lower Mainland. |

Start With One Habit — Add the Rest Over Time
None of the 10 habits above require specialist knowledge or significant time investment. The ones with the highest impact — stopping chemical cleaner use, fitting drain screens, and knowing your shut-off valve — cost nothing at all. The scheduled tasks — water heater flushing, sump pump testing, and perimeter drain cleaning — take an afternoon each year. The professional services — drain cleaning, hydro jetting, and camera inspections — cost a fraction of what emergency repairs and water damage restoration cost when these systems fail undetected.

Frequently Asked Questions
Q: Why should I stop using chemical drain cleaners?
A: Chemical drain cleaners use caustic acids or lye that generate heat during the reaction. This heat softens and warps PVC drain lines, corrodes metal pipe fittings and rubber seals over repeated use, and damages older cast iron and galvanized steel pipes already weakened by age. They mask symptoms while accelerating pipe deterioration. A drain snake, hydro jetting, or professional drain cleaning are safe and effective alternatives.
Q: How often should I flush my water heater in BC?
A: Once a year is the standard recommendation. In BC communities with harder water — including Chilliwack, Abbotsford, and parts of the Fraser Valley — flushing every 6 to 8 months is beneficial. Annual flushing removes sediment buildup, extends tank lifespan, maintains heating efficiency, and gives you the opportunity to test the TPR valve and check for early signs of corrosion.
Q: When should a BC homeowner schedule a perimeter drain inspection?
A: Every 3 to 5 years for homes with modern PVC perimeter drains. Every 2 years for homes built before 1985 with clay tile, concrete tile, or Orangeburg pipe. Always before the fall rainy season begins — October is the latest sensible timing for Metro Vancouver and the Lower Mainland. Any basement dampness during heavy rain is an immediate trigger for inspection regardless of the last scheduled date.
Q: What is the most important plumbing maintenance task for a BC homeowner?
A: Knowing where your main shut-off valve is and confirming it operates correctly. In any plumbing emergency — burst pipe, failed supply line, major leak — the main shut-off stops the damage immediately. Homeowners who cannot find or operate their main shut-off in an emergency experience significantly more water damage than those who can. This costs nothing and takes five minutes to establish.
Q: How do I know if my perimeter drains need cleaning?
A: The most common signs are basement dampness or water seepage during heavy rain, soft or saturated soil along the foundation perimeter, and slow-draining window wells. However, many failing perimeter drain systems show no surface symptoms until they fail during a significant rainfall event. For homes over 20 years old, a scheduled professional inspection is more reliable than waiting for visible symptoms.
