Hot water in cold water line. No water heater

Hi guys. My complex has two main water lines coming in, one for cold water and another for hot. I don't have a water heater. All of units in this building are like this as well. My problem is that the hot water is somehow backwashing into the cold water line. I asked the plumber and he didn't know what could cause it for only my unit to be affected and not the whole building. This wasn't always the case and started randomly. Does anyone have any ideas on what might cause this? Not sure where else to ask. submitted by /u/momobozo [link] [comments]
