Hi. I've just replaced a stud wall which held the shower over a bath and refitted the existing shower bar valve on new brackets with new compression fittings on the existing pvc pipes. I've just noticed that there is a leak when the shower is running from behind the hot water inlet. It must be the compression fitting but I have read contradictory things about how to fix it: to tighten more or not; put ptfe/other on the olive or not, etc. Where should I start in trying to stop the leak?
Thanks for any help.
