Arrived on site customer stated that they are having an issue with t&p valve leaking and noticed expansion tank was on the hot side and icemaker connection is leaking. Upon inspection found that the expansion tank has failed and it is located on the hot side and the connection at the fridge is leaking. Replaced expansion tank and installed on cold side and made new connection to fridge tested work and everything appears to be in working order and there appears to be no leaks at this time.
