Mr Coeur de Lion Posted October 16, 2007 Share Posted October 16, 2007 Had a minor leaky joint for months and have been trying everything to stop it. It's on a wall tap, the screw adaptor that connects the tap to the pipework in the wall. I bought some pate that goes on the thread, but didn't get any filasse (sp) or hemp as I believe it is called in English. Do I need this too or will the pate be enough?

Mr Coeur de Lion Posted October 16, 2007 Author Share Posted October 16, 2007 PTFE is failing miserably. These are new joints yet they won't bloody well seal! The cold side is fine, it's the hot just won't seal. I am getting frustrated with it. Even the plumber failed (he was the first to have a go at it). If I culd just get it to seal, this will be the first time in 2 years that we haven't had any leaking plumbing! So near, yet so far,,,, Link to comment Share on other sites More sharing options...
Gluestick Posted October 16, 2007 Share Posted October 16, 2007 That takes me back! Bosswhite and hemp.If the threads are so very badly cut that a good daffy of PTFE wont seal it, then Houston, we have a problem!Isn't there a square face that abuts another square face and will take a fibre washer?If all else fails, afraid it's either a new tap or new fitting; or both.In desperation I would probably file off most of the chrome plating and fill the threads with soft solder. Then PTFE.If it still leaks after that, then afraid it's off to your friendly local brico or plomberie for new taps...........Can empathise BTW: at first we were going to call our house La Petite Barracque de fuites!Brico Depot list hemp in their catalogue, incidently. Whether they have it or not is an entirely different matter. Link to comment Share on other sites More sharing options...
Chancer Posted October 16, 2007 Share Posted October 16, 2007 I have often used one or more fibre washers inside the joint in this situation.Failing that drain the pipe, dry the joint and use a thick epoxy resin, wait 24 hours before repressurising.

Gyn_Paul Posted October 17, 2007 Share Posted October 17, 2007 The usual threaded tap + wall-mounted female 'plate' (found in old coldwater kitchens and - more typically - outside taps), is a 1/2" taperfit surely?In which case Plumber's Mate or Boss White or their french equivalents+ hemp should make a proper water-tight seal. Whether you can persuadethe tap to screw up tight and finish at the right angle for you isanother matter entirely !If it still leaks, then you have a hairline crack in the brass. Bin itand start again. You will drip your way through the replacement cost inabout a year otherwise.The quality of brasswork (esp. from the cheaper plumbing outlets) isnot what it was 20 years ago, it seems to me. For example, a showermixer for spray or jets I bought recently from one of the multiples(NOT, as it happens Brico Depot this time) as part of a shower cabinetpackage, dripped constantly from one of its hose connections despitetrying every combination of fibre and rubber washers - with and withoutadded PTFE. It was only when I gave up and dismantled the whole thingfrom the shower, then took it apart, did I discover that it wasn't thehose connection which was the source of the leak, but a tiny crack inthe body which opened up when the 3 bar or so pressure was applied toit. 2 minutes with the soldering kit put it right, but, really,that should never have got past quality control. p Link to comment Share on other sites More sharing options...
Mr Coeur de Lion Posted October 19, 2007 Author Share Posted October 19, 2007 Finally solved the problem (I think).Got the filasse from Brico, but struggeled putting it on. Became very hairy!Thought I'd give the PTFE one more chance before searching the net for instructions on putting the hair on. So ended up tapering it. 2 layers at the front, going back to 3 layers in the middle and 4 at the end. So far, so dry. Link to comment Share on other sites More sharing options...
