A Season-by-Season Well Maintenance Checklist for Kentucky
South-central Kentucky's weather swings from icy winters to heavy spring rain to dry late-summer stretches — each season puts different stress on a well system.
Spring: watch for the effects of heavy rain
Check for any turbidity or cloudiness after the season's first heavy storms — see our article on karst and cloudy water if you notice this
Walk the area around the wellhead for new depressions, standing water, or ground movement after wet weeks
Confirm the well cap and casing seal are intact — spring is when a compromised seal matters most, given how much rain moves through karst terrain quickly
Summer: demand and drawdown season
Irrigation, lawn watering, and general household use all peak in summer — this is when a marginal well yield or an undersized pump shows its limits first
If pressure drops noticeably during heavy-use periods (watering the lawn while someone showers, for instance), that's worth a look before it becomes a full outage
Extended dry spells can lower the water table enough to affect wells that are already running close to their yield limit — if you notice new sputtering or air in the lines during a drought, don't ignore it
Fall: the best time for a proactive checkup
Fall is a good window for a full well inspection — flow rate, tank pressure, and pump amperage — before winter, when a failure is more disruptive and repairs are colder, slower work
Address anything marginal now rather than waiting for a winter emergency
Winter: freeze protection is the priority
Insulate exposed supply lines, especially anywhere a line runs through an unheated crawlspace, garage, or along an exterior wall
Well houses without heat should have some form of freeze protection (heat tape, a small heater, or adequate insulation) — a frozen well house is one of the most common winter emergency calls
If a hard freeze is forecast and you have a known weak point (a line that's frozen before), address it proactively rather than waiting to see if it happens again
Year-round basics
Get a bacteriological water test annually, and after any major flooding or nearby ground disturbance
Keep the area immediately around the wellhead clear of standing water, debris, and anything that could compromise the seal
Know your pump's approximate age — most submersible pumps last roughly 8-15 years depending on usage and water conditions, and knowing where you are in that range helps you plan rather than react
