Well pump, pressure tank and booster

Read the water source, pump, pressure tank, switch, dynamic pressure, flow and water quality as one system.

VERT / GREEN

Record pressure, pump cycling, flow and water quality before changing equipment.

JAUNE / YELLOW

Short cycling, unstable pressure or low flow can have several causes: tank, pump, well, filter or piping.

ROUGE / RED

Dry-running pump, contaminated water, wet wiring or abnormal pressure: stop and obtain diagnosis.

Interactive triage

This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.

Pump starts very frequently
Check precharge, tank, pressure switch and leaks before replacing the pump. Pressure drops during use
Measure dynamic pressure and available flow. Water becomes cloudy/contaminated
Address potability/source first before optimizing pressure. Pressure/flow log
Log values to detect changes over time.

Useful tools and data

Pressure gauge
Measured flow
Well records

What the professional checks

Test pump/switch/tank
Assess well yield
Coordinate treatment and pressure
