Connecting 15mm mains water feed to 22mm bath tap

[spongobongo]

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.

yes just use a 22/15 reducer

cheers. Thought it would best to check rather than sit red-faced in my bathroom.

Better still use a 15mm flexi with a 3/4" tap connector. You can get them with a built in service valve for about £3.50.

or go one better with an end feed 15mm to ¾" tap connector... don't forget the service valve of course

cheers gigz and leakydave. In the end I used a 15mm flexi with a 3/4" tap connector. It worked a treat.

I won't bore you with the trials and tribulations of my bathroom re-fit over the weekend, suffice it to say that getting a 170cm bath out of a 165cm gap involved lots of chiselling, swearing and brute force.

if the bath was plastic it would be easier to cut it in half... if steel... lots of effort required...

It was steel, as is the replacement. However, I had the forethought to install a 165cm bath this time. It took ages but well worth the effort.
