A new well pump installation from Legacy Water Well includes everything from pump sizing to final startup testing. Whether you are putting a pump in a newly drilled well, replacing an outdated system on a property you just purchased, or building a new home on acreage, we make sure the pump matches the well and the household demand.

Every installation includes:

• Well assessment — We measure static water level, well depth, well diameter, and recovery rate to size the pump correctly.
• Pump and motor selection — Sized to your well's specific characteristics. A 250-foot Trinity Aquifer well feeding a 3-bathroom home needs a completely different pump than a 100-foot Paluxy formation well on a small ranch.
• Complete assembly — Pump, motor, stainless steel drop pipe or PVC (depending on depth), torque arrestor, check valve, safety rope, and submersible wire.
• Electrical hookup — Control box, pressure switch, and wiring from the wellhead to the pressure tank.
• Pressure tank setup — Proper pre-charge and pressure switch calibration so the system cycles correctly from day one.
• Startup and flow testing — We verify GPM output, amp draw, and pressure cycling before we leave.

North Texas well owners draw from two primary aquifers, and each one requires different pump sizing considerations:

Trinity Aquifer — The most common aquifer in Parker, Wise, Hood, and western Tarrant counties. Wells typically range from 200 to 600 feet deep with moderate to good production rates. Most homes on Trinity wells need a 1/2 HP to 1 HP submersible pump set 20–40 feet above the pump intake to account for drawdown.

Paluxy Formation — Shallower wells, often 80–200 feet, found in parts of Hood, Somervell, and Erath counties. These wells sometimes have lower yield, which means pump sizing has to account for slower recovery. Oversizing the pump on a low-yield Paluxy well is one of the most common mistakes we see — it pulls water faster than the well can produce, leading to pump damage and dry cycling.

This is why a proper well assessment matters before we ever order a pump. The cheapest pump is not always the right pump, and the biggest pump is almost never the right pump. We size it to the well, not to a catalog.

We install premium Grundfos and Franklin Electric pumps, but here is the truth: a $2,000 pump installed wrong will fail faster than a $1,200 pump installed right. The most common installation mistakes we see when called out to fix another company's work:

• Pump set too deep — Sitting in sediment, pulling sand, burning out the motor.
• Pump set too shallow — Not enough submergence, running dry during peak demand or drought.
• Wrong wire gauge — Voltage drop over a long run causes the motor to overheat and fail prematurely.
• No torque arrestor — On startup, the motor torque can twist the drop pipe and damage the well casing.
• Pressure tank undersized or not pre-charged — Leads to short-cycling, which kills pumps.

Every Legacy Water Well installation follows manufacturer specifications and industry best practices. We do it right so you do not have to call us back in two years.
