Choosing a Water Level Controller: A Buyer's Checklist
Use this checklist before you buy any water level controller — ours or anyone’s. A controller is a ten-year purchase; ten minutes of thinking now beats years of workarounds.
1. What are you sensing?
One overhead tank is the simple case. Add an underground sump, a borewell, or multiple tanks and you need a controller designed for source + destination logic: fill the top tank only when the bottom tank has water, and protect the pump from both directions.
2. Wired or wireless sensing?
Short, accessible cable route → wired (cheaper, dead simple). Finished building, long or impossible cable route → wireless. Read our detailed comparison before deciding.
3. Which motor, which phase?
Match the controller to the pump: single-phase for most homes, three-phase for societies and industry. Three-phase adds its own failure modes (phase loss, phase imbalance) — the controller should protect against them, not just switch.
4. What protection is built in?
The minimum worth buying: dry-run protection, overload protection, and voltage protection (high and low). These aren’t features, they’re the difference between a controller and a timer with opinions. Motors die from dry runs and voltage events far more often than from age.
5. Manual override that a human can find
Power cuts, maintenance, odd situations — someone will need to run the pump manually one day. Check that the override is obvious and physical, not buried in a menu.
6. Connectivity: convenience or requirement?
Connected controllers show live levels, log every fill, and alert you to anomalies. For a single home it’s a meaningful convenience; for a society or factory, the audit trail alone justifies it. Either way, the device must do its core job fully offline (see our FAQ).
7. Who installs and who answers later?
A controller is only as good as its commissioning — sensor placement, level calibration and protection thresholds are site-specific. Buy from someone who installs, and who will still answer in year three. This is why Devyami sells through trained local dealers.
8. The spec-sheet sanity check
Before paying, confirm on paper: rated motor capacity (HP), supported sensor types, protection list, warranty period, and IP rating if the controller lives outdoors or in a wet pump room.
