Hi all
Quick question on hot water piping. I currently have a 15mm hot supply to a kitchen sink which follows a tortuous route and therefore takes a long time to deliver hot water and then at a low flow. Whilst doing other work I made provision for an alternative feed, but was wondering what to do about capping off the existing one.
The existing feed is concreted beneath floors of inhabited rooms and it would not be practical to try to find the branch point that feeds the sink. Is there a problem with simply capping off the existing supply at the sink (and leaving a run of "standing" water). Or should I tee the old and new feeds together? Not sure what that would achieve apart from perhaps moving the run of water.
TIA
Phil
