can anyone link me to the regs concerning condensate pipes. particullary to the part where it says you can increase the pipework to 32mm and not have it lagged. i've read it in threads on this forum but cannot find where it says you can do this in the regs.
edit :that wasnt too clear, it's regarding the running of condensate in an external situation.

It's mentioned in MI's. Boiler specific. Must read current MI's when installing a familiar boiler, they are periodically changed with reference to these issues.
that's why i asked paul. Was thinking of fitting an ecotec plus 831 (M.I state max 3 meters in 22mm od dia plastic pipe otherwise it's only a pumped option) but the equivalent bosch M.I seem to give way more options. considering the ecotec plus has a syphoning trap i can't see the problem myself as long as there is a good fall on the 32mm.
i'll phone vaillant in the morning and see what they have to say.
