How to Fix Low Water Pressure in a Single Faucet · Step 6 of 6
In this video
Begin reassembly by screwing the retaining nut back on over the new cartridge. Hand-tighten it, then give it a final snug turn with pliers if needed. Next, screw the chrome dome cap back on. Place the handle back onto the cartridge stem, making sure it is oriented correctly. Insert the set screw back into the side of the handle and tighten it with the hex key. Once everything is reassembled, slowly turn the main water supply back on and check the faucet for any leaks.
Goal: Complete the repair and verify the leak is fixed
- Do not overtighten the retaining nut or the set screw, as this can damage the plastic threads or the cartridge.
- Turn the water on slowly at first to check for leaks before turning it on fully.

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.
