    Default Pressure Loss

    We are running our second year on a BHR side by side extractor and vacuum. We are working on getting our stuff setup for the year and we cannot get the vacuum gauge on the extractor to reach more than 20- even with all the mainline valves closed. Where should we be looking for pressure leaks? Any routine maintenance that i missed after year one? Last year we were pulling 27 inches.

    Have you tried a different gauge?

    Is there a vacuum regulator that may have been knocked out of adjustment? Can you hear any vacuum leaks?

    I have a valve on the woods side of the vacuum gauge on top of the pump. Shut the valve and if the gauge spikes to 28 or so, no problem with the vacuum pump.
