pipes sweating?

Answer 1

Pipes sweat due to humidity in surrounding air, and water in pipes cold. toilets will do the same thing. Go to store & buy insulation & put on pipes. (hot & cold ) Will help prevent sweating & keep hot water from cooling off as quick

Answer 2

Pipe sweating is caused by uninsulated water pipes being in a place that is warmer than the water inside the pipes. The cold water in the pipe and the warm air around the pipe, causes the pipe to sweat. The more humid the warm air is around the pipe, the more it sweats. The same thing happens if you have uninsulated hot water pipes passing through an unheated area in the winter, They lose heat, right out through the pipe, causing sweating. It all has to do with heat transfer .

Answer 3

You don't specify which pipes you are referring to! Are they water, sewer, vent, A/C drains, A/C refrigerant pipes? Depending on the type of pipe, their location, type of weather, area of country you reside in, are all factors that should be considered. As you see from the answers given by the others here, they assume you are talking about water pipes, and start giving facts, before they even know the facts, pertinent to your case. Any answer, before knowing what you are asking, is best taken with a grain of salt.
