Fixed the problem, when I located the valves.. I found out one of the connections to the 2nd zone valve had been put together in a very Sh..ty manner.. no electric tape, no capping of the wires, no protection at all.. the wires had eroded and broke the connection, just enough to were they would touch intermitently. Hence causing zone 2 to be closed every now and then. When the valve was closed the pump would still be running, heated the water in the line warped the fitting coming out of the pump and popped the outgoing line from the pump.. the pump is still working fine, never had a lack of water..
Now that I have corrected the problem, everything seems to be working fine, I will continue to monitor it.. thank you for your help and advice
