Minimum Water Pressure

Your water pressure depends on your home's water system. It’s important to consider water pressure when buying a new tap or shower. Buying a product with a minimum water pressure that’s too high for your home will result in poor performance.

- With a combi boiler you can usually expect between 1 and 2 bar

- With a gravity system (cold water tank in attic) you may have as little as 0.1 or 0.2 bar upstairs, and perhaps 0.5 bar downstairs

- With a high pressure unvented system (hot water cylinder, no cold water tank) you will generally have between 1 and 3 bar

You can install an item with a low minimum pressure rating on a high pressure system, but avoid installing an item with a high minimum rating on a low pressure system! Read our guide to water pressure to learn more.
