First, Find Where the Water Is Coming From
Bradford White builds durable tanks, but no water heater lasts forever, and a leak almost always has a specific source. Before you assume the worst, dry everything off and watch where water reappears. Most leaks fall into one of four spots: the temperature & pressure (T&P) relief valve on the side or top, the cold-water inlet and hot-water outlet connections up top, the drain valve at the bottom, or the tank itself.
Look up first. Water runs downhill, so a puddle on the floor often originates from a fitting near the top. Check the threaded nipples and flex connectors where the supply lines meet the tank. If those are dry, run your hand along the T&P valve and its discharge pipe. A persistent drip there usually points to thermal expansion or a worn valve, not a dead tank.
If the connections and valves are dry but water keeps pooling under the heater, the leak is likely inside the steel tank, where the glass lining has failed and the steel has corroded through. That is not repairable, and the unit needs replacement.
Common Bradford White Leak Causes
Loose or failed T&P valve. This safety valve opens if temperature or pressure climbs too high. In Greater Vancouver, high incoming water pressure (sometimes above 80 psi) can make it weep. A weeping T&P valve can mean the valve is worn out, or it can be a warning that pressure or temperature is genuinely too high, which needs investigation, not just a new valve.
Drain valve drips. The plastic or brass drain valve at the base can loosen or fail to reseat after a flush. Sometimes a simple snug-up or a cap fixes it.
Corroded supply connections. Where copper or galvanized fittings meet the tank's steel nipples, dissimilar-metal corrosion can create slow leaks over the years.
Internal tank failure. Bradford White tanks use a sacrificial anode rod to slow corrosion. Once that rod is consumed and the glass lining cracks, the tank rusts from the inside out. A leak from the body of the tank is the end of the road for that unit.
What You Can Check Safely Yourself
You can do a few low-risk checks before help arrives. Confirm the drain valve is fully closed and snug. Look at the supply-line nuts and gently verify they are not obviously loose, but do not overtighten and crack a fitting. Place dry paper towel under each suspect spot and check it in an hour, which tells you the true source.
If the leak is active and significant, shut off the cold-water supply valve on the pipe entering the top of the heater. For a gas Bradford White model, turn the gas control knob to OFF or PILOT. Leave the work involving the gas valve, burner, and any internal access to a licensed gas fitter. Water and gas appliances do not mix with guesswork, and BC requires gas work to be done by certified technicians.
Repair or Replace, and Who Handles It
A leak at a valve, fitting, or the drain is usually a straightforward repair. A leak from the tank body means replacement, especially on a unit past roughly 10 to 12 years. Many Bradford White residential tanks carry a 6-year tank warranty, with longer-warranty models available, so check the rating-plate serial for the build date before paying for a new one.
Water heaters in Greater Vancouver are serviced by our parent company, CanroHeat. Repair costs typically range from a modest valve or fitting fix to a full tank replacement at the higher end, and a same-day swap is often possible when a tank has failed. We will not quote blind, so call 604-359-1081 for an exact quote after we see the unit.
If you ever smell gas near the heater, do not flip switches or light anything. Leave the home, then call FortisBC at 1-800-663-9911 or 911, and then call us at 604-359-1081.
