A private well rarely announces its problems. Pressure drifts, a pump runs a little longer than it used to, or a faucet looks cloudy after a rainy week, and the homeowner may not notice until something becomes a bigger job. A simple yearly calendar gives a Missouri household a predictable routine for looking at the system, writing down what was seen, and deciding when outside help is needed. This guide is an independent reference, not a service provider, and it describes general checks rather than specific repairs.
Why a Calendar Helps
Missouri weather swings quite a bit from season to season. Heavy spring rain, hot and humid summers, occasional ice storms, and dry stretches in late summer each put different stress on a well, its pump, and the ground around it. A calendar ties each check to a season so that the same items are looked at under similar conditions. Over time, that consistency makes changes easier to spot.
Spring Checks
Spring is a good time to look at the outside of the well and the land around it. Walk the area around the wellhead and note whether the ground slopes toward the casing, whether any puddles collect there, and whether mowing or equipment has disturbed the cap or vent.
- Confirm the well cap and vent screen are in place and not cracked, loose, or missing insects screening.
- Check that surface water from downspouts, driveways, and low spots drains away from the well.
- Look for new soil settling, bare patches, or erosion close to the casing.
- Run a few faucets and note the sound and steadiness of the flow.
Summer Checks
Summer is when water use rises. Lawn watering, pools, and guests can all shift the way the pump cycles, and a hot season can also bring changes in taste or clarity that are easy to miss.
- Note how often the pressure tank and pump appear to cycle during a normal day and during heavy use.
- Watch for any sputtering, air at the faucets, or a noticeable drop in flow during watering.
- Look at a clear glass of water from the kitchen tap in good light for cloudiness or sediment.
- Keep a short note of any changes in smell or taste, along with the date and the weather.
Fall Checks
Fall offers a calm window to review the system before cold weather arrives. Leaves, yard debris, and seasonal rain can all affect the area around the well, and the pump house or enclosure, if one exists, should be ready for colder nights.
- Clear leaves and debris from around the wellhead and the pump house, if there is one.
- Check that any enclosure door closes fully and that no gaps let in animals or drafts.
- Review the pressure switch and gauge readings against your notes from earlier in the year.
- Confirm that any outdoor hose bibs connected to the system are shut off and drained as intended.
Winter Checks
Winter brings freezing risk. Missouri cold snaps can be short but sharp, and a pump house or exposed plumbing that is not protected may fail quickly. A winter check is mostly about looking and listening, not opening equipment.
- Check that any heat source in the pump house is working safely, or that insulation is in good condition.
- Listen for the pump running longer than usual, which can point to a leak or to a supply that is struggling.
- Note any frost near exposed pipes or the pressure tank.
Records to Keep
A calendar is only useful if the notes are kept. A single notebook or a shared digital file works well. Record the date, the season, what was checked, what was seen, and any unusual weather that week. Keep copies of past water test results, the well completion record if you have one, and receipts for any service visits. When a question comes up years later, these records can show whether a change is new or has been happening gradually.
When to Call a Professional
Many checks on this calendar are simple looks and notes. Some issues need someone with proper training and tools. Call a qualified local professional if the pump runs constantly, if pressure drops suddenly, if the water changes color or smells noticeably different, if you see standing water or damage at the wellhead, or if the pump house has any electrical concern. Do not open electrical boxes or pressure tanks yourself if you are not trained to do so. For questions about the safety or quality of the water itself, a state-certified laboratory can run the tests you need, and your notes from this calendar will help them and you interpret the results.
A well is a long-lived system that rewards steady attention. A small, repeated routine across Missouri seasons is often the simplest way to notice trouble early and to make a good decision when a problem does appear.
