UVC and MHRV drains - where to run

[jamiehamy]

Hi all, 

 

The location of the UVC and MHRV units in the house is not particularly near to any soil pipes. It can be done but a bit of a faff. It would be much easier to have a straight run right outside. 

 

Is this acceptable? 

 

Thanks, J

UVC blow off can go outside but needs to be downwards and into a drain of sorts. MVHR is just condensate so assuming it doesn't freeze it can do the same
