Low water pressure in sink faucet Clogged
In most cases, a slow running tap will occur because of a low flow rate or low water pressure. For instance, if your flow rate falls below 10 litres per minute, it's going to be frustratingly slow to run.
Almost anytime you run into low flow in a faucet it's caused by clogging somewhere between the shutoffs and the aerator. Sometimes it's calcium buildup and sometimes with a multi-turn shutoff valve it's the rubber washers in the valve that deteriorate and occasionally break apart.
If you only get a trickle, the hose and/or angle stop is clogged. Replace the faucet supply and aim the new one into the bucket, if it's still clogged then your angle stop is bad. If you get full pressure, the faucet is clogged and needs to be replaced.
If you've cleaned the aerator and the water flow is still weak, there may be a clog in the pipes. As time goes by, mineral deposits build up in your pipes. This will slow water flow and, eventually, may even cause your pipes to burst. Now is a good time to call in a professional plumber.
A clogged aerator is one of the leading causes of low water pressure in the kitchen sink. It's a relatively easy fix, too. The aerator is in place to break up a solid stream of water into multiple thin streams. Air is the splitting factor, hence the name.
The short answer is low water pressure in your home arises due to a number of causes. Some include a shut or blocked water meter valve, mineral buildup clogs pipes, corroded pipes, or even a crack in the main city supply pipe to your home.
Clogged pipes: If pipes become clogged, these blockages can disrupt water flow through your pipes. With the flow disrupted, water pressure will also go down. Pipes need to be cleaned out or replaced to address the issue. Corroded plumbing: Clogs can be fixed by cleaning out or replacing small piping sections.
The most common cause of this is when the tap's O-ring becomes worn over time. This makes the tap harder to turn due to extra friction and for those without strong hands, a stiff tap can become impossible to use.
The O-ring, washer, and valve seat are the most likely causes of a dripping faucet. Remove these parts carefully and check if they are worn or have excessive water sediment buildup. Worn pieces need to be replaced with exact matches. Dirty parts need to be thoroughly cleaned.
In most cases, the easiest way to increase a faucet's flow rate is by replacing the aerator. Try looking for a higher gpm model to allow for more gallons per minute. If you live in a low water pressure area, an aerator designed to restrict water flow might be reducing the flow too much.
Flush cold water.
Run all cold-water faucets on the property beginning with the faucet closest to the water line. Let all run at the highest flow (or fully open) until water is clear and temperature is constant. Then turn off all faucets in reverse order.

Clogged aerators and clogged cartridges are two of the most common causes of low water pressure in a sink. The aerator is the tip of the faucet that the water comes out of, while the cartridge is found underneath the sink handle and enables you to stop and start the flow of water.
Flushing the Pipes. Attach a hose to one of the faucets or an outdoor tap, ensuring the other end is positioned in a drain or outside where water can flow freely. Open the faucet and let water flow through the pipes for a few minutes. This helps flush out loose sediment and debris, improving water flow.
If the aerator is clogged, it can restrict the flow of water and cause the faucet to run slow. To clean the aerator, you can remove it from the faucet and soak it in vinegar for a few hours. Then, rinse it off and reattach it to the faucet.
One of the most common causes of low pressure to a kitchen or bathroom sink faucet is debris or mineral buildup in the aerator. The aerator is the tiny screen that you see at the end of your faucet.
One of the common reasons for a sudden drop in water pressure is the clogging of pipes. Over time, pipes can become clogged with mineral buildup, rust, or debris that block water flow.
And if you still can't pinpoint the problem, a trustworthy plumber can help diagnose and fix water pressure issues.
There are many reasons why your taps may lose water pressure. It might be the fault of a blockage, corrosion, or a lack of pressure at source. In order to fix the problem, you'll need to first identify precisely what the cause is.
