UK Showers Installation & Water Pressure Compatibility[edit]
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[edit]
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[edit]
- 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[edit]
| Shower Type | Wall Preparation | Pipework Maintenance |
|---|---|---|
| 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[edit]
- 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.
