The four parts that decide whether you have water

A well system is simpler than it looks. Knowing what each part does makes the difference between describing a symptom and guessing at a cause.

The pump lifts the water. Most deeper wells here use a submersible pump sitting down in the casing, while shallower systems may use a jet pump at the surface. Which one you have changes both the failure pattern and the cost of reaching it.

The pressure tank stores it. The tank holds a cushion of pressurised water so the pump does not start every time someone washes their hands. It contains an air charge above a bladder, and that charge is a maintenance item rather than a fitting.

The pressure switch decides when the pump runs. It starts and stops the pump between two set points, commonly a thirty to fifty or forty to sixty pound range. Switches are inexpensive, they fail with contacts pitted or burnt, and they are a frequent cause of a system that appears dead.

Treatment makes the water usable. Hill Country well water is typically hard, sometimes carries iron or sulphur, and always needs to be tested rather than assumed. Treatment is sized against a test result, not a description.

Know where everything is before it fails. The well head, the pump breaker, the pressure switch and the tank are often scattered across a property, and the first cold morning without water is a bad time to find them. Five minutes now, and a photograph of the switch settings while the system is working, makes the next call much shorter.

Reading the symptoms before assuming the worst

A pump replacement is the expensive outcome, so it is worth ruling out the cheap causes first.

Rapid on and off cycling is nearly always the tank. If the pump starts and stops every few seconds while a tap runs, the tank has usually lost its air charge or the bladder has failed. It is a far smaller job than a pump, and running a well pump in that state is what destroys pumps.

No water at all starts with power, not the pump. Check the breaker and, where fitted, the control box before anything else. A tripped breaker on a well circuit is worth resetting once, and if it trips again, stop and have it looked at rather than holding it in.

Air spitting from taps means the system is drawing air. That can be a dropping water level, a leak on the drop pipe or a failing check valve. It is a real symptom and it needs investigating rather than running the pump through it.

Sudden discolouration or silt is a change worth logging. Water that turns cloudy or carries grit after being clear for years can indicate a well problem or a nearby disturbance, and it is a reason to test rather than to fit a bigger filter.

Gradually weakening pressure over months is different from a failure. That pattern suggests a declining water level or a wearing pump, and it deserves measurement rather than a part swap.

Drought, yield and looking after the system

Yield is the constraint that no equipment choice can get around.

A well can have good pressure and poor yield. Pressure is what the tank and switch deliver; yield is how fast the well refills. In a dry summer a low yield well can run fine for showers and still not sustain irrigation, which is a capacity problem rather than a fault.

Storage is how you manage low yield. A holding tank lets a slow well recover overnight and supply the house at a decent rate during the day. It is the standard answer where drilling deeper is not a sensible option.

Protect the pump from itself. Running a well dry is the fastest way to lose a pump, and low water cutoff protection is inexpensive next to a replacement. If the system has ever run dry, that protection is worth fitting.

Test annually, and after anything unusual. Bacteria and nitrate testing every year, plus a test after flooding, nearby drilling or any change in taste, smell or clarity. Nobody else is doing it for you.

Know the well head and keep it sealed. The casing should be capped, above grade and clear of standing water and irrigation overspray. A compromised well head is a contamination route straight into your supply.

Keep a record of the system's normal behaviour. Cut in and cut out pressures, roughly how long the pump runs to refill the tank, and what the water has always looked like. A well that is changing is much easier to diagnose when there is a baseline to compare against.

How a call plays out

The phone is answered around the clock, holidays included. Tell us whether there is no water at all or weak water, whether the pump is cycling rapidly, and whether the breaker has tripped. If you know whether the pump is submersible or a surface jet pump, say so, because it changes what we bring.

Helotes and northwest Bexar County are on our daily route, with overnight dispatch. We check power, switch and tank before condemning a pump, test water rather than guessing at treatment, and are straight with you about when the honest answer is a driller rather than a plumber.
