External condensate pipe size

[landlordray]

Hello,

I have a rental property and had a new combi boiler fitted 2 years ago.
No problems at all with the boiler, my only niggle is that the external condensate pipe is 32mm and fully covered with black insulation.

This pipe runs almost 3 metres across the outside wall of the kitchen and then a further 2 metres round a corner to the drain.
As the property was tenanted at the time I ( and the tenant ) had just accepted this.

This is really unsightly and now that the tenants have left and I am looking to re-let the property, I would like to have this changed, as I feel this is putting people off when they come to view the property as this hits you in the eye as soon as you approach the front door.

Could the 32mm ( black insulated ) pipe be replaced by a 40mm ( or larger ) none insulated white PVC pipe which would look more cosmetically acceptable?

thanks

Could the pipe not be run mostly internally instead?

32mm is minimum. What part of the country are you?

Hi, no the pipe runs from the boiler vertically about 2 feet, then outside.
There is no facility to run the pipe internally due to kitchen cupboards etc.

The OP is suggesting a LARGER one not a smaller one, Simon. But he wants to run it uninsulated.

Just saying 32mm is minimum so the world is his mollusc when it comes to something bigger.

I always run mine in 40mm uninsulated.

Yes that's it exactly

so 40 mm un-insulated would be OK ?

What is actually considered good practice then? 32mm uninsulated is okay?
OP - in what part of the country is this house and is it urban, rural (exposed or coastal), or suburban?

MI's state 32. I use 40. Always have more 40 bits than 32. For your standard winter 40 uninsulated would be no problem.

2010 110mm was freezing solid. Dripping tap left without repair.
