expat paul Posted November 29, 2008 Share Posted November 29, 2008 Hi,I've just had a help plea from a friend, who is in the process of fitting a new kitchen in his flat. His problem is fitting the 40mm pvc waste pipe from the sink to the existing system which is a metal 42mm OD pipe.My only thought is to heat up a 40mm joint (manchon) to get it soft and force it over the metal pipe. Anybody got any other ideas ?thanks Link to comment Share on other sites More sharing options...
powerdesal Posted November 29, 2008 Share Posted November 29, 2008 Some plumbing expert will probably be along soon but I would have thought that cross slotting the plastic, thinning it with sand paper, softening it and pushing it into the metal pipe, then do a wrap joint with fibreglass / resin would work.

tj Posted November 29, 2008 Share Posted November 29, 2008 HiThe pipe from the sink should be inside, not outside the metal waste pipe. You say the OD of the metal pipe is 42, so the 40 PVC should'nt be far out, he can try thinning the PVC, belt sander, grinding wheel etc. Link to comment Share on other sites More sharing options...
Le Plombier Posted November 29, 2008 Share Posted November 29, 2008 Does the steel pipe have a thread, if so a female iron to copper connector and run the waste in 42 copper instead of pvc, male iron to copper if a socket is present on the pipeThe 42 copper will fit the standard plastic trap outletYou would have to be able to solder as joints in copper would need solder fittingsIf it's not threaded you can use a 42 metal connector and a 42 galvanised barrel nipple, the connector is a two peice clamp designed for jointing pipes where there is no threadWith a solution such as this you will get proper watertight jointsYou would need to go to a professional plumbing and heating merchant as I doubt these fittings would be available in a bricoLe Plombier Link to comment Share on other sites More sharing options...
jondeau Posted November 30, 2008 Share Posted November 30, 2008 It is quite possible that a 40mm universal compression coupling will fit the 42mm pipe.These plastic compression fittings have a fair bit of tolerance in the body and rubber olives. I have fitted them to both copper and iron pipes. I have no idea if they are available in France though.Screwfix lists a limited range of them on their website.

Le Plombier Posted November 30, 2008 Share Posted November 30, 2008 I have found a cheap solution for you Look on Cedeo.fr websiteSearch for Raccor Flex Seal , Code 1701803It is a rubber connector with two jubilee clips, the reference is for the 32/40dia one but they do 42/50dia as wellThe joint is suitable for your application and will take a pressure of 0.5 barCost about 12/15 eurosCedeo are a national plumbing and heating outlet, they should have a branch near youLe Plombier Link to comment Share on other sites More sharing options...
