If you have a sink in your home where the hot water pressure is low but cold is fine, it can indicate an issue with your water heater. Typically, if your hot water heater is having issues that cause low water pressure when the hot water is running, it won't affect only one faucet in the house.

What would cause only the hot water pressure to be low?

If your cold water pressure seems fine but the pressure of your hot water is not, the shut off valve on your water heater might not be fully open. If that valve is partially closed, it will restrict the flow of hot water, leading to low pressure for the hot water only.
