Problem Guide
Low Water Pressure? Find Out What Is Restricting the Flow
Low pressure can be isolated to one fixture or affect an entire building. The cause may be a valve, pressure regulator, piping restriction, leak, water supply or well-system issue.
What This Problem Can Mean
Pressure complaints should be diagnosed by determining whether the problem is local to one fixture, one branch or the entire property. That distinction helps narrow down the actual cause and avoid unnecessary replacement work.
Warning Signs
Weak flow at several fixtures
Pressure drops sharply when two fixtures run
One fixture has much lower flow than others
Pressure changed suddenly
Well pump cycles unusually or pressure fluctuates
Visible leak or unexplained water use accompanies low pressure
Possible Causes
Partially closed or failed valve
Pressure-reducing valve problem
Corroded or restricted piping
Fixture or aerator restriction
Hidden leak
Well pump, pressure tank or supply-system issue
What To Do Now
Note whether the problem affects one fixture or the whole building
Check whether the issue is constant or only during high use
Look for obvious leaks
Schedule diagnosis if the pressure change is persistent or sudden
What Not To Do
Do not randomly adjust a pressure regulator without measuring system pressure
Do not increase pressure above safe plumbing limits
Do not ignore sudden low pressure with signs of a leak
Do not replace fixtures before confirming the source of a whole-building problem
