A well pump running constantly in Florida usually means a waterlogged pressure tank, a leak, or a failing pump — it wastes power and wears out the pump, so it's worth fixing promptly.
Handle it soon — these get more expensive with time.
Common causes:
• A waterlogged or failed pressure tank
• A leak in the system dropping pressure
• A worn pump that can't build pressure
• A stuck or misadjusted pressure switch
• Letting a constantly running pump burn itself out
• Assuming it's the pump when it's the pressure tank
• Ignoring a plumbing leak driving the cycling
• A contractor who isn't a state-registered septic or licensed well contractor — this is licensed work in Florida, so verify the credential and any permit
Why does my well pump run constantly?
Most often the pressure tank has lost its air charge (waterlogged), so the pump never gets the signal to stop, or there's a leak bleeding pressure, or the pump is worn and can't build pressure. A constantly running or rapidly cycling pump wears out fast and wastes energy, so diagnose it before the pump fails.
Is a constantly running well pump a problem?
Yes — beyond the wasted electricity, constant running or short-cycling shortens the pump's life, turning a cheaper repair (often the pressure tank or switch) into a full pump replacement if ignored. A licensed well pro can tell whether it's the tank, a leak, or the pump and fix the actual cause.
Well pump replacement: $500–$2,500 (typical ~$1,300)
A shallow-well jet pump is cheapest; a deep submersible pump pulled from a deep well costs more.

Florida licenses this trade at the STATE level (FL DOH (septic, FS 381 / FAC 64E-6) / Water Management District (well, FS 373)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
