Boxing in a pipe that suffers from condensation

Insulate it. Boxing it? Nah.. won't work.

Isulating & boxing it in would work together. So long as where the pipe enters & exits is sound.

The pipe will be close to freezing as it goes through the house. Its not a case of humidity, its a case of temperature difference on this one.

Yes exactly - water vapour condensing on a cold surface. I tried to suggest (perhaps incompetantly) that minimising the water vapour (humidity) will reduce the condensation. I didn't mean it will eradicate it.

Insulating the pipe should help.

Had condensation from a cold water mains pipe in our downstairs toilet a few years ago and once I insulated it and boxed it in it was fine.

EDIT - Used the same insulation that iamcornholio mentioned in their post.

I know what you are saying but it wouldn't solve the problem.

I get it under my sink in my kitchen unit. No water there. The house is as dry as you like but it happens to be the incoming mains & the coldest place in the house. Now me fitting an extractor in the kitchen to remove the water vapour would work but the most benefit would come from the extractor dropping the air temperature so its closer to the pipe temperature so less condensation would occur.

Hence to say it gets a bit of lagging, that is it. I like my house warm....

I agree but we don't know that as its a utility room in an old barn that the air isn't wringing wet most of the time anyway. Personally I'd be looking to reroute the waste pipe if at all possible.

No ... not unless the pipe leaks

The insualtion will act as a barrier so that no air will hit the cold pipe, and therefore no air will condense on the cold pipe and give up the moisture otherwise held in suspension. Air will not condense on the insualtion

The simplist solution is to insulate the pipe and then box it in as proposed. Job done

Yes, or the proper stuff from somewhere like wickes

I think the pipe is a waste pipe so would be larger then 22mm.

Buy some of this stuff:

Wrap it round the pipe, hold in place with sellotape or maybe plastic ties.
