Location of Pipes

Your plumbing placement may be the cause of hot water emanating from a cold tap.

Pipes’ Proximity

Plumbing frequently has to squeeze into small spaces. Consequently, it is typical for the hot and cold water lines to travel in parallel and near one another before ending at the faucet. The cold-water line, however, may be impacted by the hot water pipe’s heat if they are too close together.

Heat Transfer for Ventilation Ducts

Your ventilation ducts’ metal surfaces may feel warm to the touch as a result of your forced-air heating system. If your cold-water pipe is near or in contact with the ducting, some of that heat may seep into it.

Buildup or Corrosion in Pipes

These conditions can happen to pipes over time and change the temperature of the water that comes out of your taps. The reason why warm water is flowing from your cold tap may be due to outdated or damaged pipes. In this instance, fixing the problem could require replacing the impacted pipes.

Problems with the Water Heater
