Well Pump and Water System Service
Pressure tanks, switches, short cycling, dry-run protection.
About this serviceGreater Austin
Leander is a city that arrived on top of ranchland, and a lot of properties here sit somewhere in the transition: a well that still works, a city connection that just went in, or a house at the end of a line that was sized before the neighbourhood beyond it existed. Each of those situations has its own plumbing problems, and none of them are covered by ordinary advice.

When a city line reaches a property that has always had its own water, the connection itself is straightforward and everything around it is where the mistakes happen.
The two supplies must be physically separated. Not valved apart, separated. A crossover, including one left in place as a temporary convenience during the switch, can push untreated groundwater into the public main. This is the part that matters most and it is the part most often left half done.
Decide what happens to the well before the changeover, not after. Keeping it for irrigation and livestock is legitimate and usually worthwhile, and it needs a completely independent pipework system with no shared fittings, plus backflow protection on anything that touches the city side. Abandoning it means proper decommissioning: a well left open is a direct route into the aquifer for surface contamination, and plugging it correctly is a regulated job rather than a matter of putting a lid on it.
Your house plumbing was tuned to a well and now is not. Well systems typically run at a lower and more variable pressure than a city main. After a switch, fixtures see higher and steadier pressure, and things that had been fine for years start weeping. That is not a coincidence and it is not the new supply being faulty: it is old washers and old stops being asked to do more. A pressure reducing valve at the point of entry is usually part of a well done changeover.
Treatment usually needs revisiting. Equipment sized for well water, iron filters especially, is often unnecessary on treated city supply and can sit in the line doing nothing but restricting flow and needing maintenance. City water instead brings chlorine or chloramine, which is a carbon filter question rather than an iron one.
Keep the well documented. Depth, casing, pump details and the decommissioning paperwork if it was plugged. It matters at resale and it is nearly impossible to reconstruct later.
Plenty of Leander properties are, and the failures are consistent enough to be worth naming.
Short cycling is nearly always the pressure tank. A tank that has lost its air charge has almost no usable volume, so the pump starts and stops repeatedly, which is what destroys pumps. The tank and the pressure switch are cheap. The pump is not, and it is frequently replaced when the tank was the fault.
Pressure that sags in the shower points at the switch settings, a waterlogged tank or a clogged screen far more often than at a failing pump.
Air spitting from taps means the water level has dropped near the pump intake, or a suction-side leak. During a dry spell in the Hill Country the first is common and the pump needs protecting from running dry before anything else.
Sand and grit wear valve seats, fill toilet tanks and shred cartridges. A sediment filter after the pressure tank is the cheapest protection in the system.
Know your recovery rate. A well that supplies a household comfortably may not supply a household plus irrigation plus a full house of guests. Sizing storage rather than upsizing the pump is usually the right answer.
Leander has extended its water network quickly, and a house at the end of a run can genuinely be short of pressure in a way that has nothing to do with its own plumbing.
Establish the number before assuming anything. A gauge on an outside hose bib, read at a quiet hour and again at seven in the evening. If the evening figure collapses, the constraint is outside your property. If both readings are low and steady, it is more likely a restriction inside it.
Elevation costs you pressure. Roughly half a pound for every foot of rise. On the higher ground west of town that is a real subtraction, and it explains why identical houses at different elevations report different showers.
Distinguish pressure from flow. Pressure is the push and flow is the volume delivered. A long service line, an undersized meter or a partially closed valve can leave pressure looking acceptable while flow is poor, and the symptom people describe is always the same: fine on its own, useless when anything else runs.
What can be done on your side. Check the main shut-off and the meter valve are genuinely fully open, which catches more cases than anyone expects. Replace flow-restricted or scaled fixtures. Look at the service line diameter and length across a large lot. Where supply pressure is honestly low, a pressure booster with a small storage tank is a legitimate solution rather than a workaround, and it should be sized against measured figures.
What cannot. A reducing valve cannot raise pressure, and no fitting inside the house improves what arrives at the meter. Being sold a repipe for a supply-side constraint is the failure mode to watch for.
Rock, and plenty of it. Excavation on this side of Williamson County frequently means limestone rather than soil, which changes both the method and the price of anything buried. Boring often beats trenching, and depth should be established before a price is agreed.
Hard water either way. Well or city, mineral content here is high enough to scale heaters and tankless exchangers and to seize mixing cartridges. Test before buying treatment and size against the measured figure.
New stock, so installation faults rather than age faults. Most Leander housing is recent, so when something goes wrong it is more often how it was fitted than how old it is. That is good news: a workmanship defect is a one-time correction.
The phone is answered around the clock. On a pressure complaint the first thing we ask for is two gauge readings at different times of day, because that pair of numbers usually tells us whether the problem is inside your property line or outside it, before anyone is charged for a visit.
Williamson County coverage is dense and same-day is the normal outcome across Leander and out toward the lake, with genuine emergencies moved ahead of scheduled work. Pricing is agreed before anything starts.
FAQ
Yes, and for irrigation and livestock it is usually worth keeping. It needs a fully independent pipework system with no shared fittings, and backflow protection anywhere it could reach the city side. The two supplies must be physically separated, not merely valved apart.
Proper decommissioning and plugging, which is a regulated job rather than fitting a lid. An abandoned open well is a direct path for surface contamination into the aquifer, and the paperwork matters at resale.
Well systems usually run at lower and more variable pressure than a city main. After a changeover, old washers and old stops see higher steady pressure and start weeping. A pressure reducing valve at the point of entry is normally part of doing the switch properly.
Usually not, and left in the line it restricts flow and needs maintenance for no benefit. City supply brings chlorine or chloramine instead, which is a carbon filter question. Have the treatment train reviewed rather than inherited.
Almost always the pressure tank has lost its air charge, so there is no usable volume and the pump cycles. The tank and switch are inexpensive and the pump is not, and pumps get replaced for this far too often.
Either the water level has dropped near the pump intake, which is common in a dry spell, or there is a leak on the suction side. Either way the pump needs protecting from running dry before anything else is investigated.
That pattern points outside your property, to peak demand on a growing system rather than to your own plumbing. Take a gauge reading at a quiet hour and again at seven in the evening, and the gap tells the story.
Pressure is the push, flow is the volume actually delivered. A long service line, an undersized meter or a half-closed valve can leave pressure looking acceptable while flow is poor. The tell is a fixture that is fine alone and useless when anything else runs.
Not if the constraint is on the supply side, and that is the mis-sale to watch for. Nothing inside the house improves what arrives at the meter. Where supply pressure is genuinely low, a correctly sized booster with a small storage tank is the honest answer.
Same-day is normal across the Leander ZIP codes and out toward the lake, with genuine emergencies moved ahead of scheduled work.
