External condensate

[Mgrant]

If having to have the condensate discharge externally, Is 32mm 1.25inc or 1.5 inch 40mm waste pipe best? The instruction say a minimum of 32mm.

 

[Chalked]

Always . The bigger the better!

 

[ShaunCorbs]

bigger always best but depending on length of run i wouldn't want to go really over 3m unless frost protection is present

 

[plumben]

i always use 40mm/1.5" even if its just a short external run

 

[Mgrant]

Its only a 300mm run. Is that because with a bigger pipe there is less chance of freezing?

 

[townfanjon]

Nah , 32 mm defo ok

 

[townfanjon]

Sorry yes, personally I have never seen any bigger

Social housing down here now want 32mm lagged with weatherproof armaflex, it's a nightmare.

Just extra hassle and a bit overkill IMO, expensive as well!

what armaflex just a tad more than normal (thick) round here about £10 + the dreaded for a 3m length

 

[Mgrant]

So 1.25 inch is sufficient then

it will be 1.5 would be better

 

[gassafe]

it will be 1.5 would be better

1 1/4 for me... Gotta stop somewhere... 2" would be even better I suppose

Seen one in 15mm speedfit yesterday I normally use 32mm with black lagging.

location also to be taken in to consideration 3m on a flank wall 10m up will be more likley to freeze than a metre in the corner next to the kitchen door
