Quick Answer: Glenmore’s water system is gravity-fed from elevated reservoirs above the valley floor. Homes at lower elevations can experience static pressure well above 80 PSI, the maximum recommended for residential plumbing. This excess pressure silently destroys water heaters, faucets, and appliances over time. A functioning Pressure Reducing Valve (PRV) is your home’s only defense against these gravity-fed surges.
If you live in Glenmore and find yourself replacing water heaters every seven years or fixing leaky toilets every few months, the culprit may not be “bad luck”—it’s likely your water pressure. High water pressure is a “silent killer” because it rarely causes immediate floods; instead, it applies constant, excessive force to every seal, joint, and gasket in your home.

Why Glenmore is a High-Pressure Zone
The Glenmore-Ellison Improvement District (GEID)—which is currently integrating into the City of Kelowna water utility—distributes water using a complex network of elevated storage reservoirs. Because water flows by gravity from these heights (like the Rojem Reservoir) to the valley floor, the pressure increases naturally. For homes in lower elevations near Sonora Park or Harvey Avenue, the raw pressure at the property line can easily exceed 100 PSI—well above the BC Plumbing Code maximum of 80 PSI.
The Broadview Incident: A Real-World Warning
The risk in Glenmore isn’t theoretical; it is a structural reality documented by local events. On June 13, 2025, a failure at the Broadview Pressure Relief Valve Station sent a sudden, substantial surge of high water pressure to approximately 300 homes in the Clifton-Glenmore area. According to reports from Castanet, this incident caused “exploding” hot water tanks, flooded basements, and widespread plumbing damage. Crucially, the City of Kelowna noted that homes with effective in-home safeguards, such as a functioning Pressure Reducing Valve (PRV), were largely protected from the surge.
What is “Safe” Water Pressure?
The BC Plumbing Code, based on the National Plumbing Code of Canada, sets the acceptable range for residential water pressure at 35 to 80 PSI.
- 80 to 100 PSI: Above code maximum; plumbing components experience elevated stress, and seal wear accelerates noticeably.
- Above 100 PSI: Significantly elevated risk; this range is what blows washing machine hoses, destroys water heater safety valves, and cracks toilet fill assemblies.
Signs Your Pressure Reducing Valve (PRV) Has Failed
A PRV typically has a service life of 8 to 15 years. Because they usually fail in the “open” position, they allow the full force of the street main into your home without warning. Watch for these red flags:
- Water Hammer: A loud banging or thumping sound when a tap is shut off quickly.
- Premature Appliance Failure: Water heaters failing before the 10-year mark.
- Running Toilets: Fill valves that leak or run constantly even after repair.
- Forceful Showers: Water that feels aggressively strong or splashes excessively.
The Crucial Partner: The Expansion Tank
Whenever a PRV is installed, it creates a “closed system” where water cannot flow back toward the street. When your water heater runs, the water expands; without a thermal expansion tank to absorb this extra volume, the pressure inside your heater can spike dangerously. The BC Plumbing Code requires an expansion tank in these closed systems to prevent tank failure.
How to Protect Your Home From High Water Pressure
Water pressure that consistently exceeds 80 PSI is a sign your PRV needs professional attention, and it’s not always obvious without the right equipment. A licensed plumber can test your pressure quickly and accurately, and recommend the right solution for your home.

Frequently Asked Questions
Glenmore is topographically varied. Because the water system is gravity-fed from elevated reservoirs, homes at lower elevations (closer to the valley floor) receive higher static pressure than homes on the hillside.
A Pressure Reducing Valve (PRV) is a mechanical device that steps down high municipal water pressure to a safe level for your home. They generally last 8 to 15 years before the internal components fail.
While it rarely causes immediate injury, it is a leading cause of catastrophic property damage. It can burst washing machine hoses and cause water heaters to fail, leading to significant flooding.
This is “water hammer.” It occurs when high-pressure water stops suddenly, sending a shockwave through your pipes. It is often a sign of a failed PRV.
Yes, if you have a PRV installed, it creates a closed system. The code requires an expansion tank to handle the thermal expansion from your water heater, preventing pressure spikes.
