just replaced bathroom,when taking the old bath out we noticed that the cold water pipe was soaking all along the entire pipe,we let it dry out as the floor was also wet,we put it down to the old bath leaking,anyway the new suite as been fitted for over a month so i decided to check under the bath, and again all along the cold water pipe is droplets,which i assume is condensation the 15mm pipe is clipped to the party wall and outside wall,i have some 15mm foam lagging but it will only go over 3/4 of the pipe,does anyone have any suggestions.
