Water Supply Pressure Dashboard

The default band is 2–5 bar typical building supply (above ~5.5 bar many codes require a pressure-reducing valve). Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

Yes — sustained high pressure (above roughly 5–5.5 bar) is hard on plumbing: it stresses pipe joints and fixture seals, accelerates water-heater wear, makes taps and toilets more prone to leaks and 'water hammer', and increases water waste. Many plumbing codes require a pressure-reducing valve above a threshold for exactly this reason. The cheap, common failure it causes is a burst braided supply hose under a sink or behind a washer — a major flood source. If this dashboard shows you consistently high, fit and set a PRV to the 3–4 bar range.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
