Prepare pipework and install electricity supply

To prepare the pipework and install the electricity supply for your electric shower head, follow these steps:

Firstly, ensure you have the necessary tools, including a drill, screwdrivers, a pipe cutter, and a spirit level. It is also important to have the electric shower unit and any additional fixtures and fittings needed. Before beginning any work, prioritise safety by turning off the electrical supply at the mains and double-checking with a voltage tester.

Next, you will need to run a single 15mm pipe from the cold water supply near the storage tank to the wall where the shower will be installed. Hold the shower unit in position and mark where the inlet pipe and power supply cable are located. Before drilling into the wall, use a pipe and cable detector to check for any hidden pipes or cables. Drill the holes for the pipe and cable at the marked locations, ensuring the cable hole is the appropriate size based on the length of the run and the kilowatt rating of the shower unit.

Now, fit an isolating valve and the correct connector for the unit into the pipe. Run the electric cable from the shower unit position to a ceiling-mounted double-pole pull-cord switch, ensuring it is not fitted in Zone 1 or 2 as per IEE wiring regulations. Attach the electric cable from the isolating switch to the power unit, and secure a pipe from the cold water main supply to the shower unit. This will be how the water passes through the main valve.

Finally, attach a non-return valve or stop tap to the pipe to isolate the shower's water supply from the rest of the building. Ensure that the pipe is securely connected to the shower unit using a compression fitting to prevent leaks.

Secure the shower unit and shower head to the wall

Fitting an electric shower is a feasible DIY project, but it is important to follow safety guidelines and manufacturer instructions. Before installing the shower, ensure you have the required tools, including a drill, screwdrivers, a pipe cutter, and a spirit level. You will also need to acquire the electric shower unit and any additional fixtures needed.

To secure the shower unit and shower head to the wall, first, prepare the pipework and install an electricity supply. This involves running a single 15mm pipe from the cold water supply near the storage tank to the wall where the shower will be installed. Hold the shower unit in position and mark where the inlet pipe and power supply cable are located. It is crucial to use a pipe and cable detector to check for hidden pipes or cables before drilling into the wall.

Next, drill a hole in the wall for the electric cable. The size of the cable required depends on the length of the run and the kilowatt rating of the shower unit. Run the cable from the shower unit position to a ceiling-mounted double-pole pull-cord switch, ensuring it is not fitted in Zone 1 or 2 per IEE wiring regulations.

Now, you can secure the shower unit to the wall. Hold the back unit against the wall, covering the electric cables and the water pipe. Loosely connect the shower unit to the water supply pipe to ensure a proper fit and cover any holes. Some electric showers may come with a template to trace and cut out the required space. Once you have marked the designated screw holes, remove the shower unit and set it aside. Drill the marked holes for the screws and any additional holes for the electrical and water pipes to access the back of the shower unit.

Finally, hang the electric shower unit on the mounting bracket and secure it in place according to the manufacturer's instructions. Ensure that any gaps between the unit and the wall are sealed with waterproof sealant to prevent water ingress.

Before turning on the water supply and testing for leaks, follow the manufacturer's guidelines to connect the electrical wiring to the shower unit, which may include connecting live, neutral, and earth wires.
