Water Heater Leak Repair in Richmond
Fast, licensed water heater leak diagnosis and repair in Richmond — T&P valves, drain valves, tank corrosion, inlet/outlet connections and tankless components. Gas-certified, insured, serving BC since 1999.
Quick answer
If your water heater is leaking in Richmond, switch off its gas or power supply and shut the cold water feed, then call a licensed technician. Most tank leaks come from a corroded tank bottom, T&P valve, drain valve or inlet/outlet connections — the first three are repairable or signal replacement; tankless leaks often involve O-rings, condensate lines or freeze damage. We offer 24/7 water heater leak repair across Richmond and Greater Vancouver.
A leaking water heater is one of the most common — and most disruptive — plumbing faults. Even a slow drip can rust out the cabinet, damage flooring, and promote mould growth. The good news is that most water heater leaks in Richmond are straightforward to diagnose and fix once the source is correctly identified.
Richmond's high water table and low elevation mean water heater leaks in basements demand fast attention to prevent flooding and mould growth.
Is a leaking water heater an emergency?
Treat a significant water heater leak as urgent. Water pooling around a gas-fired unit or near electrical connections is a genuine hazard, and a continuous leak can flood a basement or finished room within hours. If water is running or pooling, switch off the unit and close its cold-water feed valve, then call for emergency service. We respond 24/7 across Richmond.
Common causes of water heater leaks
Corroded tank (internal rust)
The most common cause in tank-style water heaters over 8–10 years old. Rust inside the tank eventually breaks through the inner lining, causing a pool of water at the base. This usually means the water heater needs replacement — we help you choose the right unit and install it the same day.
Temperature & Pressure (T&P) valve discharge
If the water heater is overheating or over-pressurizing, the T&P valve opens to relieve pressure, dumping hot water from its discharge tube. A constantly dripping or running T&P valve signals a problem with the thermostat, pressure, or the valve itself.
Drain valve leak
The plastic or brass drain valve at the bottom of the tank can loosen, crack, or fail over time, causing a slow drip. We can replace the valve quickly without draining the whole tank.
Inlet/outlet connection leak
The hot and cold water connections on top of the water heater use brass or galvanized nipples and flex lines that corrode, especially in hard-water areas. A drip here can look like a tank leak but is usually a simple fitting fix.
Internal tank weld failure
On some older or budget water heaters the welded seam along the tank side or bottom can split under pressure, producing a sudden, heavy leak. This is an immediate replacement situation.
Tankless: flow sensor or O-ring leak
On tankless water heaters, the flow sensor and water connections use O-rings that dry out and crack over time, creating small but persistent drips. A rebuild kit or sensor replacement usually solves it.
Tankless: condensate pipe blockage
High-efficiency tankless units produce acidic condensation. If the condensate drain line clogs, water backs up and leaks from the bottom of the unit. Clearing the line and flushing the heat exchanger resolves the issue.
Tankless: frozen or burst heat exchanger
In an unheated garage or crawlspace during a cold snap, the water inside a tankless unit's heat exchanger can freeze, expand and rupture the coil. This is an emergency and typically requires a new heat exchanger or complete unit replacement.
What to do right now if your water heater is leaking
- Switch off the gas or electricity at the breaker if water is near the unit
- Close the cold-water shut-off valve above the water heater to stop the flow
- Place towels, a pan or bucket to contain the water and protect floors
- Note where the water is coming from — tank bottom, valve, or connections — it helps us diagnose faster

How much does water heater leak repair cost in Richmond?
Minor water heater leak repairs — a T&P valve, drain valve, or supply connection — are a diagnostic visit plus a relatively inexpensive part swap. Where the tank itself is rusted through or has a failed weld, replacement is the only safe option; we present a no-pressure installation quote (often rebate-eligible) alongside any possible repair so you can choose what is right for your Richmond home.

Preventing future water heater leaks
Annual flushing removes sediment that traps heat and accelerates tank corrosion, and inspecting the anode rod lets you replace it before internal rust develops. For tankless units, annual descaling protects the heat exchanger from mineral scale that can cause flow restrictions and leaks. We offer affordable maintenance plans across Richmond.
This is not a DIY repair
Combi boilers are gas-fired appliances regulated under the BC Safety Standards Act. Opening the unit, touching the gas valve, or working on the flue without a valid BC gas-fitter licence is both unsafe and illegal. Diagnosing the fault is helpful — fixing it should always be left to a certified technician.
