Context: If I understand the plumbing in my garage correctly, the white lever turns off water flow to my front hose bib. Notice the blue sticker behind the level saying "front hose bib valve". Further, the white lever is turned horizontally, so no water should be going to the front hose bib.

Concern: Above the white lever is a orange lever connected to a water pressure meter. When I opened the front hose bib this morning (to ensure there was no water coming out), the pressure meter dropped to 0. But since then, it's slowly rising back up - at last check, it was at 20 psi.
Question: Is the water pressure meter indicating that water is going to the front hose bib despite the white lever indicating the valve should be closed?
