Luckily, there are easy ways that you can adjust your water pressure for each faucet. If you want to increase pressure, you can try cleaning the aerator, rinsing the filter, or flushing the water supply lines.
Check Your Faucet Cartridge
Your faucet cartridge sits deeper in your faucet than your aerator and has a hole through which water passes. These cartridges become clogged or blocked by hard water build up which produces low water pressure in kitchen faucets. Often, they just need to be cleaned.
If the kitchen is the only tap with low pressure, it's time to consider the potential causes of low water pressure in a kitchen sink so you can determine what might be causing it, and fix it. The most common causes of low water pressure in a kitchen sink are a clogged aerator or a clogged cartridge.
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.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter. If your pressure gauge reading was low, make slight adjustments to your regulator.
If the low water pressure seems restricted to a single faucet or showerhead, the problem isn't with your pipes or water supply, but with the fixture itself. If it's a sink, the most common causes are a clogged aerator or clogged cartridge.
Unscrew the nozzle and check for a broken or misaligned washer. Next you'll likely see mineral crumbles and debris collected at the screen. Rinse it all off. If it's hardened on, soak in vinegar for a bit or buy a replacement assembly.
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.
As we mentioned earlier, there could be various reasons why you aren't getting hot water in your kitchen sink. You could be having a blockage in the faucet, an issue with the water heater, or a faulty faucet cartridge. You should examine each part until you find the exact cause of the issue with your kitchen sink.
Touch faucets have a screen below the sink. The debris screens and flow restrictors required for aerators and showerheads can clog, resulting in greatly reduced flow rates.
Clogged Pipes
Even if you don't have a clog just beneath the drain, which you can clear on your own, there could be one deep down in the depths of your pipes that is difficult to get to. These deep clogs can negatively impact water pressure.
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.
Booster pumps increase low water flow in water systems or industrial equipment and transport water from a lake, pond, or storage tank for use in a home or commercial building. A household that doesn't receive enough pressure from the city water supply would need a pump to increase low water pressure.
A quick and easy way to increase water pressure (for homes supplied by a municipal water system) is to adjust the pressure-reducing valve, which can be found on the main water-supply pipe; look for a conical-shaped valve next to the water meter, close to where the main water pipe enters the house.
If you wish to reduce the water pressure to a particular faucet, turn the valves clockwise by a quarter rotation. Make sure to turn the cold and hot water valves equally to create more consistent water pressure.
The water heater is to blame.
If you only notice low pressure while using hot water, it's time to take a look at the water heater itself. Be sure to check for obvious issues such as leaks or corrosion and make sure the tank's shut-off valve is fully open.
