The most common cause of low shower pressure is a blocked showerhead, as a result of limescale build-up. These blockages obstruct the water flow, leading to reduced pressure over time. Most showers are fitted with a filter, protecting the pipework from debris, but this can become partially blocked by scale. It’s also worth checking for any kinks or damage in your shower hose.
If the water pressure seems fine when running the bathroom taps but your shower has low pressure, shower height could be an issue. Water pressure decreases with height, so as a general rule, there should always be at least one metre between the showerhead and water source or pump.
Homes with cold water storage tanks tend to have lower pressure, relying on gravity drawing down the water rather than the mains water pressure. Installing a water pump can help increase water pressure in older properties and gravity-fed systems.
