Overview
• Installation and repair of electric showers—which involves secure mounting, safe electrical connections and precise plumbing to ensure reliable performance.
• Skill level: 3 / 5 (basic electrical and plumbing understanding is required, though complex rewiring may need professional help).
• Typical duration: 1 day for straightforward installations or repairs, though full upgrades may take longer.
Safety First
• Always isolate the electrical supply at the consumer unit before commencing any work.
• Confirm that the circuit is RCD protected to reduce the risk of electric shock.
• Check water supply isolation; ensure valves are shut off or fitted with modern stop valves.
• Follow manufacturer’s wiring diagrams and installation guidelines strictly.
Tools & Materials
Item | Purpose |
|---|---|
Electric shower unit | Main appliance needing secure installation and reliable repair. |
Screwdriver set & drill | Fixing brackets, securing the unit and removing old fixtures. |
Multimeter | Test electrical connections and ensure safe voltage supply. |
Sealant & insulation tape | Ensure watertight seals around the unit and connections. |
Step-by-Step
1. Isolate power and water supplies – ensure the relevant circuit is off and the water valves are closed.
2. Remove the existing shower unit (if repairing) – carefully detach mounting brackets and disconnect wiring.
3. Prepare the mounting area – check the wall condition and install any new fixings or backplates as required.
4. Mount the new or repaired unit – secure it firmly and ensure correct alignment for drainage.
5. Connect the wiring – follow the manufacturer's diagram closely; double-check connections with a multimeter.
6. Restore power and water – test the shower for correct water temperature and pressure, and ensure that no leaks are present.
7. Final inspection – check mounting security and tidy up exposed wiring; ensure full functionality before use.
Completion Checks
• The shower operates correctly, with steady water temperature and pressure.
• All electrical connections are secure and verified with a multimeter.
• No water leakage is detected at the unit or connections.
• The unit is mounted firmly and meets relevant building regulations.
When to Call a Pro Instead
If the installation or repair work involves extensive electrical modifications, additional plumbing, or falls under strict building regulation compliance, it is advisable to consult a qualified electrician or plumbing specialist.
