A kitchen faucet with low hot water pressure can be a frustrating and inconvenient problem. There are several reasons why this issue might occur. Understanding the underlying causes can help you determine the best solution for improving the water pressure in your kitchen.

Reasons Why My Kitchen Faucet Hot Water Pressure Low:

1. Sediment Buildup

Over time, sediment and mineral deposits can build up in your pipes. That’s causing a reduction in hot water pressure. The buildup can be especially problematic in older homes or those with hard water. To fix this issue, try flushing your hot water tank by turning off the power, closing the incoming water supply valve, and opening the hot water faucet. Then, attach a hose to the drain valve on the tank and flush out the sediment until the water runs clear.

2. Corroded Pipes

If your home has older or galvanized pipes, they may have corroded over time, causing a decrease in hot water pressure. This issue can be particularly pronounced in homes with hard water. Replacing the corroded pipes with newer, more efficient ones may be necessary to improve the hot water pressure.

3. Clogged Faucet Aerator

The faucet aerator is a small device located at the end of the faucet that helps to reduce the flow of water while maintaining the pressure. Over time, sediment and mineral deposits can build up in the aerator, leading to a decrease in hot water pressure. To fix this problem, unscrew the aerator from the faucet, clean it with vinegar or a descaling solution, and then reattach it.

4. Water Heater Issues

If your hot water heater is malfunctioning, it could be causing the low hot water pressure in your kitchen faucet. A faulty heating element, a malfunctioning thermostat, or a leaking tank can all cause issues with your hot water heater. If you suspect a problem with your hot water heater, it’s best to call a professional plumber.

5. Incorrectly Installed Plumbing

Sometimes, the hot water pressure in your kitchen faucet may be low due to incorrectly installed plumbing. This issue can be especially pronounced if your home was renovated or added onto in the past. A professional plumber can assess your plumbing system and make recommendations for improvements to help increase hot water pressure.

Why is my hot water pressure low only in my kitchen?

If you’ve flushed the hot water line and the low pressure issue persists only at your kitchen faucet, the problem may be a clog in the hot water line leading to your sink. In such cases, it’s best to seek the services of a professional plumbing technician to address the issue.

Why is my hot water pressure low but cold fine?

If you’re experiencing low hot water pressure, while the cold water flows normally, there may be sediment and limescale buildup in the pipes or faucet. Alternatively, it could be caused by a partially closed or restricted shutoff valve.

How do you clear a clogged hot water pipe?


Low hot water pressure in your kitchen faucet can be caused by a variety of issues. Including sediment buildup, corroded pipes, a clogged faucet aerator, water heater problems, or incorrectly installed plumbing. By identifying the cause of the problem, you can take steps to fix it and improve your hot water pressure. If you’re not sure where to start, consult with a professional plumber for the best solution for your home.
