Hello all - we're having a weird experience with our 1950s-era home. We just had a new (high-efficiency) washing machine installed (it replaced a top-loader from the 1990s). The laundry room is on the main floor, in an extremely well-ventilated space, and the copper pipes just started condensing ("sweating") like crazy. From two loads of laundry (with the rinse cycle on cold obviously) the pipes have sweat so much that the water is literally dripping on the floor. And the condensation is distributed throughout the entire line of pipe - it's not localized in any stretch of pipe. This had never happened before - could it be a result of some feature of this new washing machine? Is the cold water drawn more slowly or constantly through the lines in a high efficiency machine? (The ambient temperature is not the problem - it's a constant 68 degrees in the house, including the laundry area). Any suggestions or insights would be great - especially since we've already spent about $3,000 on plumbing repairs and have only been in this house 18 months.
