wickes 40mm waste pipe... 43mm
Just wondering about something,
Parents are fitting a bath back into the bathroom that was changed into a shower room a few years ago, he needed some waste pipe, so nipped to the local wickes, and bought a 3 meter length of 40mm white waste pipe, He then proceeds to cut it to the size he needs, pokes it through the hole in the wall, and tries to connect it up to the trap supplied with the bath, pipe is too big, So he tries the other end, fitting it into the boss in the soil pipe, too big, then he notices printed on the side of the pipe is says it's 43mm. Reciept says he bought 40mm pipe, label on the display says 40mm pipe, didn't even know 43mm waste pipe existed, Of course as he's cut it he cant have a refund or exchange, and they wont accept it's their fault it dosent fit the bath's trap, they told him he should buy wickes brand fittings and it will all fit then, He went to Q&Q and got some real 40mm pipe instead, but i was wondering where this 43mm waste pipe comes from, some new standard or something, I am wondering if it's conduit pipe, as it's a hard plastic and not flexiable at all like the 40mm pipe, but he says he picked it up in the plumbing section, |

These have more "slop" and a big fat conical sealing washer which fits various pipe sizes. Apart from the nominal 1 1/4 and 1 1/2 inch ("sink" and "bath" waste pipe) which goes into "compression" type fittings with rubber seals, there are also solvent weld pipes. Personally I would have said you have a strong case for a refund given the clear mismatch between the labelling/receipt and the product. |

Forget about metric sizes for waste pipes; it's confusing. There are only two sizes of waste pipe: inch-and-a-half and inch-and-a-quarter. That's it. Forget about compression fittings; they're for ******s. They confuse the picture further by being slightly different diameter to solvent weld. More confusion comes in (with mm) when manufacturers specify the outside diameter instead of the inside and vice versa.
In summary: Forget the sheds. Only ever go to a plumber's merchant and get either inch+half or inch+quarter solvent weld only and you won't go wrong. |

Ahhhaaa, that could well be it, the 43mm pipe seems to be a different type of plastic to the 40mm one, it's more like electrical conduit pipe, so it could well be solvent weld pipe after all, I personally buy pipes from a builders merchant close to me, but my parents seem to not want the 'hassle' so pay over the odds at the sheds, plus he bought it on a sunday afternoon as he wanted the job finished. |

The solvent weld stuff seems to be harder and more shiny than the push fit stuff in my experience. I prefer solvent weld personally, once it is installed, then it is there forever! -- Toby... remove pants to reply |

It will fit solvent fittings and "universal" (i.e. compression) fittings. Sounds like the trap was a push fit one. That's smaller and a slightly softer plastic. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

This means that push fit (O ring) and glueable pipe fittings are non- interchangeable. However the compression fittings fit everything but are more expensive. They are dismantleable for if you get a blockage which is good. |

Well they *have* insofar that push-fit and solvent weld pipes are a different size to prevent the wrong combinations of pipe and fittings from being used.

43mm is normally the solvent weld type and 40mm is normally push fit simple

It's because 40mm is the inside pipe dimension and 43 is the outside dimension
40mm= hole size 43mm= overall pipe size Its the same when you buy 32mm waste pipe it will say 36mm on the pipe but inside dimension will be 32mm |
