Solvent weld is solvent weld, right?
Can I use the pot of MK "egaweld" I have for electrical conduits to also
weld the Marley waste pipe I've just bought? Or are they in fact different things? Cheers, Pete |

At least with the 40mm stuff I've just been looking at, push-fit and solvent-weld cannot be used together. The OD of push-fit is near enough 40mm, while that of solvent-weld is 43. The solvent-weld won't even come close to fitting into a push-fit fitting, and the pushfit would be too loose in a solvent-weld one (not to mention not welding properly). My understanding is that compression has enough give to work with either. Pete |

I don't know enough to know whether they're close enough. Pete I have a tub of Floplast solvent glue that may be used with either uPVC or ABS. It's quite likely that the egaweld would work, but personally I'd get something that positively states ABS just to be sure. Cheers Tim |

A lot of the (cheaper) solvent weld fittings are ABS, and they are interchangeable with uPVC fittings. However, I always try to find PVC parts (sometimes, you'll find mixed stock in the same bin in the sheds). PVC certainly does solvent weld better. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

True; ABS and PVC solvents are different. The last time I looked at the manufacturer's literature for the 'universal' solvent, it said it wasn't suitable for pressure applications. I'd buy the right stuff for the pipe system being used. |

Hi, That doesn't seem to concur with this: http://www.floplast.co.uk/pages.asp?...5341&catid=282 http://www.floplast.co.uk/pages.asp?...1915&catid=282 The former states that Floplast uPVC 110 systems should be jointed with SC125 or SC250 (I have this - it's the one Screwfix sells) The second link states to use exactly the same solvents on ABS. I was worried when this thread started as I'd been using SC250 on both ABS and uPVC - but the links state this is fine. Perhaps there's something funky about SC250 but it smells remarkably similar to the conduit weld I have. In both cases, there is not a chance in hell of any of the joints coming apart - I've tried on a test sample. Cheers Tim |

writes I've just checked the two types from Wickes and allowing for some variation in numbers my checks confirm that there are two different sizes for different fittings thus: Push-fit - 41mm - BS EN1451 B Solvent weld - 43mm - BS EN1566 B - Mupvc The difference in numbers suggests that there are different types of solvent-weld pipe and probably different types of solvent which need to be matched to their particular type. Both ABS and MuPVC use the same solvent system. ABS waste is thin walled, scratches easily and is the cheaper, low grade product but it is adequate for domestic use. MuPVC waste is thicker walled, less easy to scratch and can sustain higher temperatures in use. It is specifically required for prolonged discharge of hot water where ABS would soften and start to flop about but is not generally required for a domestic situation. Its higher temperature resistance makes it suitable for use as a flue for compatible boilers such as the Keston range. Both ABS and MuPVC wastes were specified under BS 5255 but have now been given different EN spec numbers which is sensible considering their different properties. The sheds used to stock MuPVC exclusively so all my stuff is done in that but on returning to buy some additional supplies at the B&Q I have noticed that the stock seems to have switched the lower cost ABS with a few odd fittings of MuPVC being sold from ABS part bins. If I want MuPVC now it will be easier to go to a specialist drainage merchant where I know I will get the right stuff. -- fred BBC3, ITV2/3/4, channels going to the DOGs |

Cheers, Pete Some (like underground soil pipes) are ABS, some (smaller waste pipes and conduits) are PVC. One solvent cement is OK on both, the other is more dodgy on the wrong one. Of course I can't remember which way round. However I havn't come across Marley solvent weld; it used to be push fit. |
