I have a prochem peak gtx with 5,300 hours on it. There seems to be a small water leak possibly coming from under the heat exchanger box and I can't pin point where exactly it's coming from. My question is could one of the heat exchangers have a small pin hole in it this causing the leak? It certainly hasn't frozen as it is always kept in a warm space. The machine performs really well and this leak doesn't affect water pressure.
