Hello, I have a new 2 zone pinnacle boiler installed, the problem is
that when you take a shower or have zone one on zone 2 heats up. I have
had check valve replaced, and it worked for a few days then the pipes
started heating up again without heat on zone 2 on?
Any suggestions?

Thanks

You need to describe the equipment. How do you get domestic hot water? How
many zones total? Do you have just circulators, or combination of
circulators and zone valves? Pictures would help
