Pretty self-explanatory subject title really.
I'm refitting my bathroom this weekend. The cold feed will be from the mains which is on 15mm copper. Obviously the bath tap requires 22mm pipe. Is it okay to fit a reducing coupling on a 22mm tail from the bath tap to the 15mm mains? I've got pretty decent mains pressure.
The alternative is to reduce the existing 28mm feed from the cold water tank in the loft to 22mm. But I'd rather not.
