Cold mains supply round the house
David WE Roberts :
Any benefit in running a 22mm 'backbone' with 15mm spurs to endpoints?
Theoretically this seems to give a higher overall capacity but I don't
know if this is necessary for normal use for basins, toilets. etc.
Doesn't that mean that you'd have to run off more before you can get a
glass of *cold* water?
