I have a Brita water filter head which has a 3/8 thread that I need to connect to a 15mm feed about 800mm away. I have used in the past a flexible tap connector hose which had a 3/8x15mm fittings but is to short at 300mm long. I cant get anything in that size which is longer so I'm thinking of screwing a 3/8x1/2inch brass bush from screwfix onto the brita head but what flexible hose do I use that is used for drinking water that is around 800mm long.
