Quick answer
The expansion tank (vessel) absorbs the increase in water volume as the system heats, keeping pressure stable and protecting the boiler. If your boiler expansion tank is failing in Port Coquitlam, a licensed technician must diagnose and replace it — this is not a DIY job. This isn't usually an immediate emergency, but it should be diagnosed by a licensed technician to restore reliable heat and prevent further damage.
What the expansion tank does
The expansion tank (vessel) absorbs the increase in water volume as the system heats, keeping pressure stable and protecting the boiler.
Signs your expansion tank may be failing
- Pressure climbs high when hot and drops when cold
- Water discharging from the relief-valve pipe
- Frequent need to re-pressurize
Important safety note
A technician checks the tank's air charge and either recharges or replaces it. Persistent pressure swings usually trace back to this part. Please don't attempt to repair or replace boiler parts yourself — book a licensed technician.
Repair or replace?
Often the expansion tank can simply be replaced. On an older boiler, if multiple parts are failing or the repair cost is high, a new high-efficiency boiler may be the better long-term value — and may qualify for BC rebates and financing. We give you honest options for your Port Coquitlam home.

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.
