Leaking Hot Water Tank Repair in Coquitlam
A hot water tank rarely leaks all at once. It usually starts as a small drip you don't notice until there's already water pooling on the floor. If you've spotted rust, moisture, or a puddle near your tank anywhere in Coquitlam or the Tri-Cities, you're in the right place.
KC's Plumbing, Heating & Drain Services has repaired and replaced hot water tanks in this area since 1993. We can tell you fast whether your tank needs a simple fix or a full replacement, and we carry the parts and tanks to handle either one the same day.
Water actively pooling right now? Call
(604) 873-3753 before it gets worse. Otherwise, here's how to tell what you're dealing with.
How to Tell If Your Hot Water Tank Is Actually Leaking
Start with the tank itself. Rust on or around the top, or water stains on the floor nearby, both mean it's starting to leak. Next, check the pressure relief valve, the small valve on top of the tank that releases pressure from excess heat. If it's stiff or hard to open, it needs replacing, and depending on the tank's condition, that can mean the whole unit.
A leaking tank can burst without warning and damage the floor, walls, or anything stored nearby, so it's worth catching early rather than waiting to see if it gets worse.

Hot Water Tank Repair vs. Replacement in Coquitlam
Repair is often the right call. If the tank has been flushed regularly, kept dry, and the gas or electrical connections are in good shape, you may only need a new pressure relief valve or anode rod. That holds whether you have a gas or electric water heater.
Here's the rule of thumb we use: if repair costs are creeping up toward half the price of a new tank, replacement makes more sense. We'll walk you through the tank's age, its expected lifespan, and what the repair versus replacement actually costs before you decide anything.
One more thing worth knowing: current BC building code requires larger ventilation piping on most replacement installs now, and the city requires a licensed gas fitter to connect both the gas and electrical. That's not optional, so factor it into any DIY plan.

Frequently Asked Questions
How do I know if my hot water tank is actually leaking?
Look for rust around the top of the tank, water stains or pooling on the floor nearby, or a pressure relief valve that's stiff or hard to operate. Any of those signs mean it's time to have it checked.
Should I repair or replace a leaking hot water tank?
It depends on the tank's age and condition. If repair costs are approaching half the price of a new tank, replacement is usually the better value. We'll give you a straight answer after a quick inspection.
How much does it cost to fix a leaking hot water tank?
It varies with what's actually wrong, whether it's a valve, an anode rod, or the whole tank. We provide a free, no-obligation quote once we've seen the tank in person, since guessing a number without that isn't useful to you.
Do you offer emergency service for a leaking tank?
Yes. We're on call 24/7 for plumbing and heating emergencies throughout Coquitlam and the Tri-Cities.
Can I replace a hot water tank myself?
You can, if you're familiar with local ventilation code, gas fittings, and electrical connections. Current BC code requires larger ventilation piping on most installs, and the city requires a licensed gas fitter to sign off on the gas and electrical work.
