Running the cold pipe below the hot

[Fallout]

Hi I usually try to run the hot pipe above the cold pipe to stop any heat transfer. How bad of a sin is having the cold running above the hot though?

Insulate them?

I wondered if most people did this too? Is only for a run of say 2 meters. Have the hot below the cold as it meant I didn't have to cross the pipes

Wherever possible you want to keep potable water cool to prevent bacterial contamination, part of the building regs.

How much of a sin - is down to your conscience.

I think you should be put in the stocks for a week and have rotten eggs thrown at you.

Requirement of the Water Regs too.

Ages since I did regs but 100mm space I seem to recall
