Water pressure plays a major role in the comfort and functionality of your home’s plumbing system. Whether you’re taking a shower, running the dishwasher, or watering the lawn, consistent and balanced water pressure ensures everything works as intended. But many homeowners don’t realize that water pressure problems both low and high, can create long-term plumbing issues if left unaddressed.
In Kelowna, where elevation changes vary wildly from Upper Mission down to the Okanagan lake, pressure issues are incredibly common. Here’s what you need to know about identifying pressure problems, what causes them, and how to adjust your system for safe, efficient water flow.
When Water Pressure Is Too Low: Causes and Solutions
Low water pressure is one of the most common plumbing frustrations. It can turn a relaxing shower into a slow drizzle and make basic tasks like washing dishes or filling a pot take far longer than they should.
Common Causes of Low Pressure
- Mineral Scale: Okanagan water is moderately hard, leading to calcium buildup inside pipes and fixtures.
- Leaks in your plumbing system
- Faulty pressure-reducing valve (PRV)
- Municipal supply issues (common during peak summer irrigation months).
- Corroded or aging pipes
- Partially closed shutoff valves
Low water pressure often develops gradually, especially in older homes where pipes accumulate mineral scale over time. It can also appear suddenly if a major leak or valve issue occurs.
What You Can Do
Start by checking simple fixes:
- Ensure faucets and shutoff valves are fully open.
- Remove aerators and showerheads to clean out hard water sediment. Read this guide to learn more about protecting your plumbing from hard water damage.
- Check for visible leaks around fixtures or appliances.
If the issue affects the entire home, your PRV may need adjustment or replacement. A professional plumber can test pressure levels, diagnose the source of the drop, and restore optimal flow.
When Water Pressure Is Too High: Hidden Damage You Might Not See
While low pressure is annoying, high water pressure can be far more destructive. Excessive pressure puts continuous strain on pipes, fixtures, and appliances, often causing problems that remain hidden until serious damage occurs.
Why does this happen in Kelowna? Because our region is hilly, municipal water systems use gravity to move water. Homes located at the bottom of hills (like in Glenmore, Lower Mission, or near the lake) often receive water at much higher pressures—sometimes exceeding 100 psi—compared to homes at higher elevations.
Signs of High Water Pressure
- Banging or noisy pipes (“water hammer”)
- Rapidly failing faucets or appliances
- Leaking supply lines
- Toilet fill valve issues
- Unusually high water bills
Most homes should maintain water pressure between 40 and 60 psi. Readings above 80 psi are considered unsafe and can BC violate plumbing codes.
Risks of High Pressure
- Burst washing machine hoses
- Premature water heater failure
- Shorter lifespan for dishwashers and refrigerators
- Increased risk of pipe leaks or ruptures
Unlike low pressure, high water pressure often requires immediate attention to prevent damage.
How to Address It
A pressure-reducing valve (PRV) is the primary control for regulating incoming pressure. If your home’s water pressure suddenly spikes or fluctuates:
- Have a professional inspect or replace the PRV.
- Install expansion tanks for water heaters to absorb pressure changes.
- Monitor pressure regularly with a gauge.
How to Measure, Regulate, and Maintain Safe Pressure Levels
Understanding your pressure levels is the first step to protecting your plumbing. Fortunately, testing water pressure is simple and affordable.
Measuring Water Pressure
Attach a water pressure gauge to an outdoor hose bib or laundry faucet. Turn on the water and observe the reading. If the pressure is outside the 40–60 psi range, it’s time to take action.
Adjusting Water Pressure
- For low pressure: A plumber may clean lines, replace restrictive fixtures, or adjust the PRV to increase flow.
- For high pressure: The PRV can be tightened or replaced, and additional components like expansion tanks may be recommended.
Preventive Maintenance Tips
- Flush water heaters annually to reduce mineral buildup.
- Replace old, corroded pipes.
- Inspect supply lines for wear or bulging.
- Schedule a plumbing inspection every 1–2 years.
Proper water pressure not only improves everyday comfort—it protects your home from leaks, appliance damage, and costly repairs.

Frequently Asked Questions About Home Water Pressure
What is the ideal water pressure for a Kelowna home?
Most homes operate best with water pressure between 40 and 60 psi. Anything above 80 psi is considered unsafe and may violate plumbing codes, while pressure below 40 psi can affect daily water use.
What causes low water pressure?
Low water pressure can result from hard water mineral buildup in pipes, leaks, partially closed valves, corroded plumbing, sediment-filled fixtures, a failing pressure-reducing valve (PRV), or municipal supply issues.
Why is high water pressure dangerous?
Excessive water pressure puts stress on pipes, fixtures, and appliances. Over time, this can lead to leaks, burst hoses, damaged water heaters, and shortened appliance lifespan.
How can I tell if my water pressure is too high?
Common signs include banging pipes, dripping faucets, frequent appliance issues, toilet fill valve problems, and sudden spikes in water bills. A pressure gauge can confirm your exact psi level.
How do I measure my home’s water pressure?
Attach a water pressure gauge to an outdoor hose bib or laundry faucet, turn on the water, and check the reading. It only takes a few minutes and provides an accurate measurement.
Can I adjust my water pressure myself?
Minor adjustments to a pressure-reducing valve are possible for experienced homeowners, but incorrect adjustments can cause damage. It’s often best to have a professional inspect and set pressure levels safely.
When should I call a plumber about water pressure issues?
Call a professional if your pressure is consistently too high or low, you hear water hammer, notice leaks, or your PRV appears damaged. Sudden drops or spikes also require immediate attention.
