How to Fix Low Water Pressure in a Single Faucet · Step 1 of 6
In this video
Before starting any work, prepare the area under the sink. Begin by shutting off the hot and cold water supply valves, typically by turning them clockwise. Place a bucket or container underneath the plumbing to catch any water that will drain from the lines. Open the existing faucet to release any pressure and drain the remaining water. Finally, use an adjustable wrench to disconnect the hot and cold water supply lines from the shutoff valves.
Goal: Shut off water and disconnect supply lines
- If you cannot find or operate the shutoff valves under the sink, you will need to shut off the main water valve for the entire house.
- Keep a towel handy to clean up any spills immediately.

FAQs
How difficult is it for a beginner to fix low water pressure in a single faucet, and how long should I expect it to take?
This project is genuinely beginner-friendly, starting with simple fixes like cleaning the aerator. While the estimated time is 3 hours, most beginners can complete the common solutions (aerator, supply lines) in under an hour. The 3 hours accounts for potential complications like corroded parts or needing to clean/replace the cartridge.
What are the essential safety precautions I need to take before starting this faucet repair project?
Always shut off the water supply to the faucet completely before beginning any work, both hot and cold lines if separate. Use a bucket and towels to manage any residual water and avoid electrical outlets. Wear gloves to protect your hands from grime and potential sharp edges.
The required tools list includes a 'TEKTON Ball End Hex and Star T-Handle Key Set.' Is this truly necessary for a standard faucet repair, or can I get by with simpler tools?
While some faucet handles or set screws might require specific hex or star keys, many common double-handle bathroom faucets only need a Phillips or flathead screwdriver and an adjustable wrench. Inspect your faucet's handle screws to determine if the specialized key set is truly needed before purchasing. Pliers can also be very helpful for aerators or supply line nuts.
I've cleaned the aerator and flushed the supply lines, but the water pressure is still low. What should I do next?
If those steps haven't resolved the issue, the next most likely culprit is a clogged or faulty faucet cartridge. You'll need to carefully disassemble the faucet handle to access, clean, or replace the cartridge. Ensure you turn off the water supply again before attempting this step.
