Editing Installation Guide: Thermostatic Shower Systems

== UK Showers Installation & Water Pressure Compatibility ==

Installing a premium shower system in a UK home requires understanding the local plumbing plumbing standard and domestic water pressure framework. Below is the technical compliance checklist for our modern and traditional shower sets.

=== 1. Water Pressure Systems Compatibility ===
Before mounting your rainfall shower head or thermostatic valve, verify your property's water system to ensure optimal flow rates:
* 🔴 '''Gravity-Fed Systems (Low Pressure, approx. 0.1 - 0.2 Bar):''' If you have a cold water tank in the loft and a hot water cylinder in the airing cupboard, you may experience low pressure. We strongly recommend installing a '''negative/positive head shower pump (1.5 Bar to 3.0 Bar)''' to achieve the luxury rainfall experience.
* 🟢 '''Combination Boilers (Combi, High Pressure, approx. 1.0 - 1.5 Bar):''' Delivers mains-fed hot and cold water on demand. Highly compatible with all our modern thermostatic shower valves. No pump required.
* 🟢 '''Unvented Mains Pressure Systems (High Pressure):''' Megaflo or similar unvented cylinders. Provides excellent high-pressure performance across all outlets. Perfect match for our twin-head rainfall systems.

=== 2. Plumbing & Pipework Connections ===
* '''Standard Pipe Centres:''' All our exposed traditional and modern thermostatic shower mixers come with standard '''150mm pipe centres''' (adjustable from 135mm to 165mm via the included offset S-eccentric union connectors).
* '''Inlet Thread Sizes:''' The valve body connections are standard '''3/4" BSP'''. The package includes robust G3/4" to G1/2" adapters to connect directly into standard standard UK 15mm copper or PEX speedfit pipework.
* '''Hot & Cold Alignment:''' By UK standard convention, the '''Hot water supply must connect to the LEFT inlet''', and the Cold water supply to the RIGHT inlet. Reverse connection will cause the thermostatic cartridge to malfunction.

=== 3. Concealed (Built-in) vs Exposed Shower Installation ===

| '''Exposed Valve''' (Traditional / Modern Sets)
| Pipework comes out of the finished tiled wall. Easy to retrofit.
| Valve is fully accessible from the front for easy cartridge cleaning.
|-
| '''Concealed Valve''' (Minimalist Hidden Style)
| Requires building a stud wall or chasing out a brick wall (minimum 75mm depth clearance).
| Ensure an integrated plaster guard is used during installation to protect the solid brass body.

=== 🛠️ Step-by-Step Fitting Overview ===
# '''Flush the Pipework:''' Prior to fixing the shower valve, always flush the hot and cold supply pipes to clear any debris, solder flux, or swarf. Debris is the #1 cause of thermostatic cartridge blockage.
# '''Fixing the Valve:''' Use a professional shower fixing kit (wall-mount bracket) to secure the pipework inside or on the wall. This prevents the valve from wobbling when users adjust the temperature lever.
# '''Sealing & Tiling:''' Apply premium silicone around the pipe inlets before screwing on the decorative wall plates (shrouds).
# '''Testing Cartridge Accuracy:''' Once installed, turn on the water and let it run. Our thermostatic cartridges are factory-preset to a safe '''38°C anti-scald stop'''. You can calibrate this manually by removing the temperature control knob if your Combi boiler output is exceptionally high.
