Pressure is the same whether hot or cold.
The issue of low hot water pressure while the cold water pressure remains fine could be caused by a clog or blockage in the hot water pipes, a malfunctioning hot water heater, or a problem with the hot water valve.
Hot or cold?
water pressure
Low hot water pressure compared to cold water pressure can be caused by various factors such as a clogged hot water pipe, a faulty hot water heater, or a malfunctioning pressure regulator. It is important to investigate and address the specific issue to restore balanced water pressure throughout your plumbing system.

The low hot water pressure in your kitchen sink could be due to a clog or blockage in the hot water line, a faulty hot water valve, or a problem with the hot water heater. The cold water pressure remaining fine suggests that the issue is specific to the hot water system. It may be necessary to check and repair the hot water line or heater to restore proper pressure.
The low hot water pressure in your shower may be due to a blockage or buildup in the hot water pipe or valve. This can restrict the flow of hot water, causing lower pressure compared to the cold water. It is recommended to check and clean the hot water pipes or consult a plumber for further assistance.
The issue of low hot water pressure while cold water pressure remains normal could be caused by a blockage in the hot water line, a faulty hot water valve, a malfunctioning water heater, or sediment buildup in the hot water tank. It is recommended to check these potential causes to identify and resolve the issue.
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.

If your hot water pressure is lower than the cold water pressure, it could indicate a problem with the hot water heater, such as sediment buildup in the tank or a faulty pressure relief valve. It may also be due to a blockage or leak in the hot water pipes. It is recommended to have a plumber inspect and address the issue to ensure proper functioning of your hot water system.
When a hot can is placed in cold water, the air inside the can cools down and contracts, creating a lower pressure inside the can. The higher pressure outside the can then crushes it.
