powerdesal Posted June 20, 2012 Share Posted June 20, 2012 I have a relatively inaccessible water drain line which is leaking at a saddle fitting. I can't get access to replace it but could do a pipe wrap repair.Does anyone know if epoxy impregnated water activated pipe repair kits are available in France ( They must be, but where?). I have searched the Castorama site without success.I assume 'bande époxy réparation des tuyaux' is the correct terminology. Link to comment Share on other sites More sharing options...
sid Posted June 20, 2012 Share Posted June 20, 2012 How about this...? http://www.castorama.fr/store/Ruban-adhesif-anti-fuites-PRDm123058.htmlI've used something similar, the equivalent of self-amalgamating tape to seal the connections on my satellite LNB. I know it's not the same pressure but the instructions say it's for leaks. Link to comment Share on other sites More sharing options...
powerdesal Posted June 20, 2012 Author Share Posted June 20, 2012 Thanks Sid, I didn't see it on the Casto site. I am just about to go to Brico in St Lo to see if they have something similar. Casto at Caen is the nearest but it's only 20 mins to St Lo as opposed to 1 hour to Caen. Link to comment Share on other sites More sharing options...

powerdesal Posted June 21, 2012 Author Share Posted June 21, 2012 Denso tape - that brings back a few memories, haven't used it for years, messy to apply if I remember correctly.Anyway, my repair efforts have come to naught and I now have to 'bite the bullet' and rip out a load of pipework and replace it - what fun !!!!!!

markthespark Posted June 21, 2012 Share Posted June 21, 2012 Denso Tape......it brings back a few memories for me too, good job someone invented self amalgamating tape, which Sid has found here in France (well done Sid)......It's ideal for making electrical junction boxes etc., pretty much waterproof too.Mark Link to comment Share on other sites More sharing options...
Théière Posted June 21, 2012 Share Posted June 21, 2012 Mark the latest stuff is silicon tape, very waterproof. Lots of suppliers via Amazon etc, never without it in my tool kit now.I only mentioned Denso for a laugh, as with the silicon tape you won't need to buy a new shirt + trousers [+o(] Link to comment Share on other sites More sharing options...

sid Posted June 21, 2012 Share Posted June 21, 2012 Duly noted, Teapot, thanks. It still is only a temporary repair though (for a leak) and I think the OP would have had to face a more complicated or difficult job eventually anyway. Link to comment Share on other sites More sharing options...
powerdesal Posted June 21, 2012 Author Share Posted June 21, 2012 Job done, loads of piping removed and now replaced - I hate plumbing !!!! Link to comment Share on other sites More sharing options...

The leak was in a 2" rising main and it was just a tiny drip from a badly soldered fitting. 3 times it was bound up with the tape but water drips still came out of the end of the tape despite full stretching etc. The company responded by sending more tape but we noticed it bonds to itself without stretching and if over stretched didn't seem to work all that well bond wise. I have used it since on smaller diameter pipes 22mm etc and also cleaned the oxide off the pipes first and had more success. Link to comment Share on other sites More sharing options...
sid Posted June 22, 2012 Share Posted June 22, 2012 For a pipe at mains pressure I would still want to do a "proper"repair. Powerdesal's was on a drain (saddle fitting), so on reflection a tapewound repair would probably be OK, and especially if this stuff is as good as it sounds. For self-amalgamating tape you have to stretch it to activate the adhesive; you're saying that this silicone stuff works without stretching, which would make it easier to use too.

powerdesal Posted June 22, 2012 Author Share Posted June 22, 2012 The pipe with the leaking saddle was in a corner, with about 2cm clearance for almost a quarter of the diameter. I found that I couldn't get any tape around the edge of the saddle so I cut out the whole section at a convenient place above and below the leak.The replacement section was about 1 1/2 m long with a swept tee, 90 deg bend, 2 x saddle fittings (including the leaking one) and passing through a 150mm thick concrete floor.--------It was not a fun job.
