7 Reasons Your Water Pressure Is Low

Cause: A partially closed valve at a fixture or the main shut-off valve into the house can restrict water flow.
Solution: Check and fully open the valves for all affected fixtures, as well as the main shut-off valve, usually located in the basement or near the main line.
6. Water Supply Issues
Cause: Sometimes the problem lies with the municipal water supplier, especially during water shortages or system maintenance.
Solution: Contact your local water supplier to report the issue and check for updates. Consider using high-pressure fixtures if reduced pressure is due to municipal regulations.
7. Clogged or Faulty Fixtures
Cause: Fixtures can collect sediment and debris, especially in faucet aerators and shower cartridges.
Solution: Unscrew the faucet aerator, clean it with soap and water, and replace it. For showers, replacing the cartridge may be necessary.
Frequently Asked Questions
Is low water pressure dangerous?
It can be if it’s caused by a leak, which may lead to water damage or mold growth.
What if my water pressure drops suddenly?
Sudden pressure drops usually indicate a problem with the pressure regulator, main supply pipe clog, or a water supply issue.
Why is only my hot water pressure low?
This may be due to a partially closed hot water valve, a faulty tempering valve, or sediment in the hot water heater. Flushing the heater might help.
By addressing these common causes, you can often restore water pressure in your home. For complex issues, calling a licensed plumber is recommended.
