Sounds good Rob, I look forward to hearing it. Mine is booked for this weekend but I'm a little less confident in the company now and may rebook elsewhere. If they'll do it, get them to reduce the pipe from 3" to 2.5" rather than flange it and create a 'wall', as such which will block flow a little more.
yes mate, thats what the chap will be doing...all the flange's are 3" the pipe work will reduce to the 2.5"
i've yet to book mine in yet...need to get a bit more cash together hopefully this time in 3 weeks all will be complete
