Rear entry supplies

Note: The final separation between pipe centres needs to be about 153 mm but absolute accuracy is not essential as the inlet elbows

are adjustable between 146 mm and 160 mm

(fig.23).

Using a spirit level, mark the route of incoming hot and cold water supply pipes at a distance of 153 mm centres.

Remove the plaster and brickwork to the required depth to conceal the supply pipework.

Note: It is advisable that pipework installed in solid walls be provided with enough free play inside a cavity to allow entry into the inlet elbows for tightening, before securing the valve to the finished wall surface.

Install the hot and cold pipework — the hot pipe must enter from the left. Make sure the finished pipework projects from the front face of the tiled surface of the wall by 9.5 mm (fig.24).

Allow for two circular recesses measuring 32 mm diameter by 14 mm depth, to accept the rear entry pipe trims (fig.23).

Flush pipework to clear the system of all debris and check for leaks.

Important: The inlet elbows contain check valves that may be damaged if debris is not flushed through prior to fitting.

Where this is not possible refer to the ‘flushing procedure’ on page 20.

Make good the wall and complete the tiling. Check that the rear entry pipe trims are sealed in with either silicon sealant or grout (fig.24).

Note: Failure to fit the rear entry pipe trims could result in the entry of water into the wall cavity.

Offer the valve, together with the inlet elbows, to the pipework making sure the inlet elbow grub screws are slack allowing the inlet elbows to be rotated to the correct position and move freely in and out of the valve housing (fig.8).

Check that the valve is central between the two pipes, then mark two diagonal fixing holes

(figs.25 and 26).
