Water Pressure Basics for Mixers & Showers (Spec-Friendly)
A clear overview of water pressure, flow, and why they matter when selecting mixers, shower systems, and valves—ideal for early-stage specification.

Choosing the right mixers and shower systems starts with understanding pressure and flow. Two homes can have the same ‘pressure’ reading but very different real-world shower performance.
Pressure vs flow
- Pressure is the force pushing water through the line
- Flow is how much water actually comes out (L/min)
Why it matters
- Some valves need stable pressure to maintain temperature
- Long pipe runs and multiple outlets reduce effective flow
- Filter, heater, and regulator choices impact performance
Project tip
When specifying, confirm minimum operating pressure for the selected valve and expected flow at the site’s real conditions.
