I'm changing downstairs manifolds in central heating to a new ones, old manifolds can only take four radiators and i wan't to fit a fifth, also old one's constantly leak. My question is, while i'm doing this job can i replace all 8mm pipe with 15mm, do manifolds take 15mm pipe or are they made for microbore only. Chris
yes they do come in 15mm, in fact they come in all manner of sizes, many a good deal larger than 15mm. a more important question is whether it will suit the rest of your system.
