Pressure Problems

Clogged aerator screens can impede flow.  Problems with the mixer valve cartridge may be a problem with single handle fixtures.  Also check for crimped water supply lines.

If only hot water has reduced pressure, the problem is likely at the water heater.  check to make sure the shut off valve is completely open.

• Clogged filter media on in-home water filtration systems will reduce water pressure.
• If you live in an older home, mineral buildup inside pipes impedes water.
• Water line leaks can cause lower pressure.

• Check the master shut off valve.  If it was shut off for repairs or other reasons, it might not have been fully re-opened.
• The pressure reducing valve may have failed in the closed position.

• The pressure reducing valve may have failed in the open position.
• Operational changes may be bringing water in from a different elevation than normal.
