Step-by-Step Guide

When it comes to bathroom faucets, the water flow can be restricted in one of two ways – via a single flow restrictor or an aerator flow restrictor. This time, let’s walk you through how to remove a single flow restrictor since it is the most frequently found water limiter in bathrooms.

Step 1: Turn Off the Water Supply

Alright, before you start descaling your bathroom sink, you gotta turn off the water supply. Look under the sink for the valve and turn it clockwise till it stops. This shuts off the water supply to the faucet.

Step 2: Remove the Faucet Aerator

Take off the faucet aerator by turning it counterclockwise with pliers. Remember to be careful while removing it, or you might end up damaging the aerator or the faucet!

Step 3: Locate the Flow Restrictor

So, you’ve taken down the aerator. Now it’s the flow restrictor’s turn to play. It’s a tiny piece of plastic or metal that resides within your faucet, looking all authoritative and stuff, controlling the water flow and conserving the precious drops.

Step 4: Remove the Flow Restrictor

You need to flex your muscles a little and grab a pair of pliers. Now, grip the restrictor firmly and twist it gently but counterclockwise. If the little guy won’t budge, no worries. Just find a small flathead screwdriver to help nudge it lose. But hey, be careful not to scratch the faucet while you’re at it!

Step 5: Reassemble the Faucet

So now that you’ve successfully extracted the flow restrictor from your bathroom faucet, it’s time to put it back together again! No need to panic. Just take your trusty pliers and secure the aerator into place.

Once that’s done, it’s time to turn the water supply back on and test out your newly modified faucet. Quick tip, though, be mindful that removing the restrictor might lead to higher water bills and have an environmental impact.
