Hi guys,


Long story relatively short, my wife bought a tap that was meant to have three inputs - Hot, Cold softened, Cold hard.


Instead, the tap has a filter input that it takes off the cold feed.

Off the cold feed it goes into a filter

The output off the filter is a thin, in diameter, flexible plastic pipe.


The connection for the thin flexible pipe to the tap is a bit odd.

- there is a Threaded Brass Pipe that is both the fixing for the tap to the worktop, and the pipe taking the filtered water

- a brass Adapter Nut (I) screws into the Threaded Brass Pipe, on the other end of the Adapter Nut a 12mm plastic Speedfit screws in

- the Speedfit then connects to the flexible thin diameter pipe.


What I am trying to do is take the Speedfit and filter out of the equation.

Instead,

- screw a 12mm flexipipe (a standard tap tail) into the Adapter Nut (I)

- the other end of flexipipe connects to the Cold Hard with a 1/2" connector.


I am concerned that the Adapter Nut is not designed to take mains pressure, as the filter and thin diameter flexible pipe would reduce this.


Is there anything I can do to make that adapter nut a better connection to withstand mains pressure? At present there is just a hard fibre washer between the brass Threaded Pipe and brass Adapter Nut.
