I've just bought a bath with Italian fittings.( Pause for laughter) I've put a pic at
No matter how tight (within reason) I tighten these fittings together, they leak. Would rubber washers or thicker washers or what make these fittings water tight?
Is there a sealant that would do the job, on its own or in conjunction with washers or something else?
The problem seems to be that the waste/ overflow fitting is chrome but it's proprietary to the bath so I don't have any choice about using it.
