Well Pump & Pressure Tank Dashboard

The default band is 40–60 psi typical cut-in/cut-out band for a residential well pressure switch. 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.

Almost always a waterlogged pressure tank. The tank stores water under an air cushion so the pump can rest between draws; when the air bladder ruptures or the pre-charge bleeds away, there's no cushion, so the pump cycles on and off rapidly with every small demand — quickly overheating and wearing out the motor and switch. Check the tank pre-charge with a tyre gauge on its Schrader valve (system drained, no water pressure): it should sit ~2 psi below the pump's cut-in. Re-charge it, or replace the tank if the bladder is torn. Short-cycling is the single most common well-pump killer.

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.
