Mlcp for me 25mm main runs and 16mm to the rads
16mm Is about the same as speedfit the non lay flat stuff so easily thread 25mm you can thread through but recommend two people one to hold the coil and the other to thread etc

We recommend City Plumbing Supplies, BES, and Plumbing Superstore for all plumbing supplies.
