High water pressure may seem like a good thing, but in reality, it is one of the most damaging conditions for a home’s plumbing system. Many homes in Vancouver, North Vancouver, Burnaby, and Coquitlam experience excessively high incoming water pressure, especially in older neighborhoods. When the pressure is too high, it puts constant stress on pipes, fittings, fixtures, water heaters, and shut‑off valves—leading to leaks, worn‑out components, and even sudden pipe bursts.
One of the strongest indicators of high water pressure is aggressive or forceful water flow from faucets and showerheads. If water sprays with unusual intensity or feels difficult to control, the pressure entering the home is likely above the recommended level. High water pressure also causes water hammer—loud banging or knocking noises in pipes when a faucet or appliance suddenly shuts off. These shocks can loosen joints, damage valves, and weaken soldered connections.
A failing PRV (Pressure Reducing Valve) is the most common reason for pressure issues. The PRV reduces the municipal water pressure—often over 120 PSI—to a safe household level of around 50–70 PSI. When the PRV becomes worn, clogged, or stuck, the pressure fluctuates or rises beyond safe levels. Many homeowners first notice the problem when toilets start running continuously, fill valves fail repeatedly, or shower cartridges wear out far sooner than expected.
High pressure is especially harmful to hot water systems. In a traditional hot water tank, excessive pressure causes the T&P relief valve to open frequently, releasing water as a safety measure. Many homeowners mistakenly believe the tank is failing, when in reality the true problem is uncontrolled pressure. In tankless systems, high pressure can cause internal sensors, flow switches, and heat exchangers to wear prematurely.
Appliance hoses—such as those for washing machines, dishwashers, and ice makers—are particularly vulnerable. High pressure can cause these hoses to bulge, leak, or burst, potentially flooding the home. Under‑sink braided hoses and the supply line to the toilet are also common failure points.
Signs of high water pressure include:
- Water hammer or loud pipe noises
- Extremely strong water flow from fixtures
- Toilets running frequently or fill valves failing
- Constant dripping from the T&P valve on the hot water tank
- Hearing pipes vibrate when water is running
- Premature failure of faucet cartridges and shower valves
PRVs typically last 7–12 years. Once they begin to fail, pressure problems become increasingly noticeable. Replacing the PRV restores safe and consistent pressure throughout the home and helps prevent leaks, fixture damage, and unexpected plumbing failures. Proper PRV installation and pressure adjustment also protect expensive appliances and extend the lifespan of the entire plumbing system.
