Condensation

[JoeyB]

I have installed a new blue plastic water supply to my house. It connects to copper with push fit connections.
The copper pipes are wet ,also the blue plastic pipe.
I dont think they leak ,just condensation.
How can I prevent this

Try lagging the pies to keep them warm, this will prevent condensation.

And the pipes as well.
Perhaps this is in your utility room with the washing machine or lots of other condensation?
