Temperature Control Thermostatic

This indicates how many water outlets you can pair with your shower valves. Choosing valves with more outlets will give you flexibility over the number of products you can add to your shower. 

Each outlet from your shower valve will divert water to the section of your shower that needs it, so each extra outlet allows you to add another product. For example: with 1 outlet you could have just a fixed shower head. 2 outlets will allow you to have a fixed shower head and shower handset. 3 will allow both of these with the addition of a body jet.

Minimum Water PressureMore information 0.5

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.
