Turning on a shower or faucet and finding that the water pressure has suddenly dropped can indicate several different problems.
Some causes of low water pressure are limited to a single fixture. Others can affect the entire property and may involve the home’s plumbing, water service or municipal supply.
Determining how widespread the problem is can help narrow down the possibilities.
Is the Low Pressure at One Fixture?
Start by determining whether the pressure problem affects one faucet or shower, several fixtures or the entire home.
If only one fixture is affected, the problem may be localized to that fixture or its supply.
If every fixture has noticeably weaker pressure, the cause may be further upstream in the plumbing system.
Check Whether Both Hot and Cold Water Are Affected
Another useful observation is whether the pressure problem occurs with both hot and cold water.
A problem isolated to hot water may point toward a different part of the plumbing system than pressure loss affecting all water entering the home.
You do not need to diagnose the exact cause yourself. These observations simply provide useful information when arranging service.
Could a Water Line Leak Reduce Pressure?
A significant leak in the water service can be one possible cause of reduced pressure.
If low pressure is accompanied by unexplained wet ground, unusual water consumption or other signs of an underground leak, the water service should be considered.
Stillwater provides water main services in Kamloops when a pressure problem is traced to a damaged private water line.
Could the Problem Be With the Municipal Supply?
Yes.
If neighbours are experiencing the same sudden pressure loss, the problem may not originate within your property.
Checking for municipal notices can help determine whether a larger water-system issue is underway.
Other Plumbing Problems Can Affect Pressure
Not every pressure issue is caused by a broken water main.
Valves, piping restrictions, fixture problems and other plumbing conditions can affect water flow or pressure. This is why replacing or repairing a water service should not be the first assumption based solely on low pressure.
When Low Water Pressure Needs Investigation
A persistent or significant pressure change throughout the property deserves attention, particularly when it appears suddenly or is accompanied by other symptoms.

Frequently Asked Questions
Possible causes range from plumbing-system problems to a damaged water service or an issue with the municipal supply. Diagnosis depends on the circumstances.
Not necessarily. A leak is one possible cause, but several plumbing and supply issues can affect pressure.
A problem limited to one fixture is more likely to involve that fixture or its immediate plumbing than the main water service.
If the change happened suddenly throughout your home, knowing whether nearby properties are experiencing the same issue can help identify whether the problem may be broader than your property.
