9 Signs Your Well Pump Is Failing

Not every water problem is the pump. A few of these symptoms point at a failing pressure tank or a clogged filter instead — but if you're seeing more than one, or your pump is past the 8–15 year mark, it's worth having a contractor look before it fails completely (which tends to happen without warning, usually on a weekend).

• Sudden, unexplained drop in water pressure — the most common first symptom. Could be the pump losing efficiency, but rule out a clogged aerator or filter first.
• Spitting, sputtering water or air in the lines — often means the pump is struggling to maintain prime, or the well's water level has dropped below the pump intake.
• Pump short-cycling — turning on and off rapidly, sometimes every few seconds. This is very often a waterlogged pressure tank, not the pump — check the tank before assuming the worst.
• Pump running constantly and never satisfying pressure — points at a worn impeller, a leak in the system, or a pump that's now undersized for demand.
• Cloudy, sandy, or gritty water — sand or sediment coming through usually means a submersible pump's intake screen is failing or the well itself has silted up; either way it's abrasive and accelerates pump wear.
• Higher electric bills with no other explanation — a straining motor pulls more current. If nothing else changed, that's a real tell.
• Unusual noise — grinding, humming, or clicking from the well house or pressure tank area (a submersible pump itself will be silent, since it's underwater — noise usually means the control box, motor bearings surfacing as vibration, or the pressure tank).
• Complete loss of water — the unambiguous one. Could still be electrical (a tripped breaker, a bad control box) rather than the pump itself, which is worth a cheap check before assuming a full replacement.
• Pump is 10+ years old and any of the above shows up — age alone isn't a reason to replace, but age plus a symptom usually tips the math toward replacement over another repair.

If you're not sure which of these you're looking at, a licensed well or pump contractor can usually diagnose over a short visit — worth doing before you're in an emergency, no-water situation where you have less leverage on price and timing.
