Water Pressure Repair in British Columbia
Weak flow, unusually strong pressure or sudden changes throughout your property can point to a plumbing problem. Proflow diagnoses water pressure issues and repairs the underlying cause for homes and businesses across British Columbia.

Water Pressure Problems Can Show Up in Different Ways
Low Water Pressure
Faucets or showers may feel unusually weak, take longer to deliver water or lose flow when another fixture is used.
High Water Pressure
Excessive pressure can place additional stress on plumbing fixtures, valves, connections and supply piping.
Pressure Changes
Pressure that suddenly rises, drops or changes while several fixtures are operating deserves further investigation.
The Fixture Isn’t Always the Problem.
Water pressure is affected by more than the faucet or shower where you first notice the problem.
A pressure issue can originate from valves, pressure-control equipment, supply piping, restrictions, leaks or other parts of the plumbing system. The pattern of the problem helps narrow down where to investigate.
Proflow can test the pressure, assess the affected plumbing and determine whether the issue is localized to one fixture or affecting a larger part of the property.
Why Has Your Water Pressure Changed?
Similar symptoms can have very different causes. Testing the plumbing helps avoid replacing parts without understanding the actual problem.
Pressure Regulator
A pressure-reducing valve or other pressure-control component may require adjustment, service or replacement.
Partially Closed Valve
A valve that is not fully open can restrict water entering or moving through part of the plumbing system.
Pipe Restriction
Aging or deteriorating piping can sometimes restrict flow and contribute to reduced water delivery.
Plumbing Leak
A leak can affect how water is delivered through the system, particularly when the problem is significant or concealed.
Fixture-Specific Issue
If only one faucet or shower is affected, the problem may be localized rather than property-wide.
Supply-Side Change
Changes affecting the incoming water supply can also influence the pressure available within the property.

What Does a Pressure-Reducing Valve Do?
A pressure-reducing valve, often called a PRV, is used in plumbing systems to control incoming water pressure before it is distributed through the property.
When pressure-control equipment is not operating as intended, the property may experience pressure that is too high, too low or inconsistent.

Pressure Reducing Valves →One Fixture or the Whole Property?
Where the pressure problem appears can provide an important clue about where to start looking.
Only One Fixture
When the issue affects one faucet, shower or fixture, the restriction or fault may be localized near that plumbing fixture.
Multiple Fixtures
If pressure is weak or abnormal throughout the property, the incoming supply, regulator, valves or distribution piping may need to be assessed.
Pressure Changes Accompanied by Water?
If a pressure change is accompanied by unexplained moisture, dripping or water appearing where it shouldn’t, the plumbing should also be checked for leakage.
What May Need to Be Checked?
The exact assessment depends on the symptoms and plumbing configuration of the property.
Common Water Pressure Questions
Pressure symptoms can look simple at the fixture while the underlying cause is elsewhere in the plumbing system.
Why is my water pressure suddenly low?
Low pressure can have several causes, including a localized fixture problem, a valve or regulator issue, a restriction, a leak or a change affecting the incoming water supply. Testing helps determine where the problem begins.
Why is the water pressure low at only one faucet?
When other fixtures have normal pressure, the problem may be localized to that fixture, its supply or nearby plumbing rather than affecting the entire property.
Can high water pressure damage plumbing?
Excessive pressure can place additional stress on valves, fixtures, connections and other plumbing components. If the pressure appears unusually high, it should be assessed.
Can a pressure regulator cause low water pressure?
A pressure-reducing valve affects the pressure supplied to the property’s plumbing. If it is not operating correctly, pressure problems may occur and the valve may need assessment.
Can a plumbing leak affect water pressure?
A significant leak can affect water delivery within a plumbing system. If pressure changes are accompanied by unexplained water or moisture, leak investigation may also be required.
