Once the Mira Honesty ERD is installed, users can divert easily between the deluge head and hand shower. The Mira Magni-Flo combines to deliver up to three times more flow, even at low pressure. The Honesty also comes with a ‘fast-fix kit’ for ease of installation, providing added reassurance for installers.

How to fit the Mira Honesty ERD

Start by isolating the water supplies. Then, decide on a suitable position for the shower unit and fittings and determine the direction and route of the water supply pipes.

Step 1

Once the supply pipes are installed slide the plastic pipe guide provided over the pipes and level using a spirit level.

Secure the pipe guide to the wall with tape to hold in position. Leave the guide in place and finish the wall.

Ensure that the recessed supply pipes protrude 25mm from the finished wall surface and are square to the wall.
