Bypass though the boiler feed valves .. Manual or auto . Anything else connected to boiler like for hot water ?

It will turn off because the water rising in the system increases the pressure, which turn the pressuretrol off. Good thing, too.Br. Jamie, osb

If you have a tankless water heater coil in the boiler it may have sprung a leak or the manual feed valve is leaking by or if you have an automatic water feeder that could be leaking by0
