Hi all I've got a Hipolito 502 which leaks at the point where the lower vapouriser screws into the fount.I have found that the chrome threaded piece which receives the vapouriser and lead washer is not bedding down - thread is gone I fear. Is there any practical solution or has the fount had its day? Obviously if the vapouriser can't be secured into the fount the whole lamp is U/S.... Siatbury
