Every site I maintain gets a 15-minute monthly walk: cycle and tag isolation valves (QR label + date/turns), check PRVs/backflows, test sump alarms, crack mixing valves, and peek roof drains. Last Tuesday at a 9‑story office garage, a sticky sump float showed up on the test and we swapped it before the first rain — no flood, no overtime. Anyone have a dead-simple PM log or app you hand to facility managers that they keep up with?
I stopped chasing apps and turned my camera into the log: during the 15‑minute walk I snap the PRV gauge and the QR valve tag, then dictate in the photo caption “L3 PRV 74→62 psi, 5 turns” so search gives me a clean timeline later. A quick video of the sump alarm test also flags sticky floats before first rain without me writing a thing.
And swapped your ‘QR label + date/turns’ for cheap NFC stickers that launch a prefilled Google Form — tap the valve, it time-stamps, autofills location, I punch PRV psi, sump test, and turns, and it drops in one Sheet. Keeps the 15‑minute walk tight; @paul_eva11’s camera trick works, but this makes trending effortless. Only caveat: basement dead zones, so I cache the form or use a Shortcut that logs to a local note and syncs later.
