Kitchen area tank uses hot water from a/c water recovery. When breaker for tank is turned on, hot water comes thru cold line. Never had this happen before until last year. I changed thermostat on tank, but it's still a problem.

One thing that can cause this problem is the old single handle Moen faucets that used the old 1225 cartridge. If you have a Moen faucet in the vicinity that either pulls straight up or straight out, you may have one of these faucets. Replace the brass cartridge with the new plastic one. Problem solved.
