In effect this means that when no gas flow is demanded inside the building, the regulator "shuts off" gas flow at the valve seat in the inlet port. However when we are doing LEAK TESTING we want the appliance OFF, since we want to know that the appliance valve isn 't itself leaking when closed. cit. Therefore if we increase the spring pressure we are allowing more gas to flow (higher pressure and flow rate). I'm not sure, Angela; I've had similar problems on other plumbing components when a component stem, like a valve stem, was broken.
