Quick answer
On a combi boiler, the diverter valve switches the unit between central heating and on-demand hot water. If your boiler diverter valve is failing in New Westminster, 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 diverter valve does
On a combi boiler, the diverter valve switches the unit between central heating and on-demand hot water.
Signs your diverter valve may be failing
- Hot water works but no heating (or vice-versa)
- Radiators warm only when a tap runs
- Lukewarm hot water
Important safety note
A stuck diverter valve is an internal component diagnosed and replaced by a technician, who then tests both heating and hot-water modes. Please don't attempt to repair or replace boiler parts yourself — book a licensed technician.
Repair or replace?
Often the diverter valve 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 New Westminster 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.
