Key Takeaways for Homeowners
- Many Dublin homes rely on gravity-fed systems, which often result in low shower pressure.
- Installing a Stuart Turner booster pump is the most effective solution for whole-house pressure.
- Check for blocked shower heads and aerators before calling a plumber.
- Ensure your main stopcock is fully open.
Gravity-Fed vs Mains Pressure Systems
Most older homes in Dublin operate on a gravity-fed water system, meaning a cold water storage tank in the attic provides the pressure for the hot water cylinder and showers below. This naturally results in lower pressure compared to modern mains-fed or unvented systems.
To achieve a powerful shower, installing a booster pump, such as a Stuart Turner pump, is often required.

Frequently Asked Questions
What is a negative head shower pump?
A negative head pump is required when the shower head is positioned above or at the same level as the cold water storage tank, meaning gravity cannot start the flow of water to activate the pump.
How much does it cost to install a booster pump?
The cost varies depending on the type of pump required (positive or negative head) and the existing pipework, but typically starts from €600 including installation.
