Check Out These 5 Reasons for Low Water Faucet Pressure

Water slowly trickling from a faucet is an annoyance, especially if it sees frequent use, like a kitchen or bathroom faucet. Low water faucet pressure can make daily chores difficult and frustrating. But it also indicates that something is wrong with the plumbing. Several factors can cause a faucet’s water pressure to go down. 

Fortunately, low water faucet pressure is a fairly common problem, and most times, the cause is easy and quick to fix. However, in some instances, it can indicate a more severe issue that requires the service of a professional plumber. 

When the low water pressure problem is localized, it is simple to remedy it by focusing on that fixture and the connected pipes. Here are a few common reasons why a faucet may have low water pressure:

Clogged aerator screen

The aerator is the first to check when a faucet has low water pressure. Most faucets have aerators at the base or inserted inside the spout. Sediments, mineral deposits, or small debris can clog the aerator over time, which results in low water pressure. 

To restore water flow due to a clogged aerator, use pliers to remove the aerator from the faucet, scrub it with an old toothbrush and rinse in water. If the aerator is severely clogged, soak it overnight in vinegar, wash it, and reattach it to the faucet.

Damaged or blocked cartridge

If the aerator is not clogged, the issue may lie with the cartridge. It is a device that controls the water flow and is connected to the faucet handle, and prevents leaks and other faults. The cartridge may require cleaning or replacement when it gets clogged due to debris, corrosion, and sediments or becomes damaged. Remove the cartridge and soak it overnight in warm water and vinegar. Clean and wash the cartridge before reattaching. If the cartridge needs replacement, it is best to call a professional plumber.

Shut-off valve

If the water pressure becomes low after utility work or repairs, consider checking the shut-off valve. A fully or partially closed shut-off valve can result in low water pressure. Ensure that this valve located on the water meter side is fully open. When open, ball valves should face the pipe direction. Twist the gate valve counterclockwise to open.

Pipe size

When the pipe supplying water to the faucet is too big, it can cause low water pressure. Consider replacing the pipe portion closest to the faucet with a smaller pipe to increase the water pressure. Ensure to only use the pipes designed for cold or hot water lines, depending on which one needs replacement.

Broken faucet

If the faucets are too old, they can break and wear out and require repair or replacement. When the valves fail to open completely, or the internal parts break, malfunction, or go bad, the faucet may supply water at low pressure. Call a licensed plumber to inspect the faucet and suggest whether repairs can suffice or whether it is best to replace the fixture. 

Resolve all water pressure issues

It is best to hire professionals from a reliable plumbing company when unable to diagnose or fix the reason behind low water faucet pressure. Also, call an expert if all faucets in the house are experiencing the problem. Experienced plumbers can determine the root cause and address it to restore the water pressure.
