Answer: Do I Need a Pressure Reducing Valve for My Water Heater in Vancouver?
A pressure reducing valve (PRV) is installed on the main water supply to reduce the incoming municipal water pressure to a safe level for your plumbing system. In some areas of Greater Vancouver, municipal water pressure can exceed 80-100 PSI, which is higher than the recommended 50-65 PSI for residential plumbing. High water pressure stresses your water heater's T&P valve, increases water heater noise (water hammer), shortens the life of washing machine and dishwasher fill valves, and can cause leaks in pipe fittings. If your home's water pressure is above 80 PSI, a PRV is recommended. If your home already has a PRV, check that it is not set too low — below 40 PSI causes poor water flow and can make tankless water heaters malfunction.
When to Call a Professional for Help
While understanding the answer to this question is helpful, some situations require professional expertise. If you are uncertain about any step, if the problem recurs, or if you notice any signs of gas odour, carbon monoxide, or electrical hazards, contact CANRO Heating & Cooling immediately. Our licensed technicians across Greater Vancouver can provide expert diagnosis and repair. We recommend professional service for any issue that involves gas, electrical components, or safety-critical systems.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
