I have read the suggestion to insulate the pipes just like with hot water pipes. However, I am concerned that while this may reduce the sweating, there still will be some condensation, but now the condensation will be trapped against the pipe.
Should I be worrying about this? If so, what should I do to minimize the potential for mildew and mold in this trapped moisture?
Second, I find that the condensation only occurs on the first few feet of pipe in from the grounde. Is it possible that conduction causes the water in the first few feet of pipe to stay cold all the time leading to heavy condensation while beyond that the water for the most part has warmed up (except when the water is actively running) so that there is much less active condensation?
