Hi, i have a flexi pipe (15mm compresion) going to a chrome pipe for a shower , then a sevice valve not chrome going to the chrome pipe then shower , i am getting a leak from the flexi to the chrome . I have nipped it up as far as i can without striping the flats on the nut and i still get a small amount seeping out from the nut when under pressure , i am going to replace the set up could anyone recomend what i should go for ie do i need a special flexi if i am going to chrome . Thanks
